SP3 New Warning/Error Message shown if contact analysis is called with wrong center distance
In case that contact analysis is called with a center distance smaller then the minimum allowed center (free of backlash) distance, a confirmation message with a warning is appearing: "Der Achsabstand im Tab 'Kontaktanalyse' ist kleiner als der spielfreie Achsabstand %5.3f (Klemmen). Dies wird zu Fehlern in der Kontaktanalyse führen. Möchten Sie fortfahren?". In case of a center distance exceeding the maximum allowed center distance (a >= (da1/2 + da2/2)) a error message is shown and the calculation is aborted: "Der Achsabstand im Tab 'Kontaktanalyse' ist grösser als der grösstmögliche Achsabstand. Die Zahnräder berühren sich nicht mehr (a >= da1/2 + da2/2)"


SP3 Hardening depth graphic not shown correctly in imperial units
Hardening depth graphic was not shown correctly for imperial units (using measured points from a DAT file). This is fixed, the results were not affected!


SP3 Improvement: line breaks in the modifications tab
A flag has been added to the modifications tab to show long text either truncated or with line breaks. The layout of the modification part of the report was also improved.


SP3 KISSsoft stopped working when opening manufacturing drawing
KISSsoft stopped working when opening manufacturing drawing (under the 2D graphics), when the face width of a gear was set to 0. This is now fixed.


SP3 Not possible to select cutting tools in 4 gear chains
It was not possible to select cutting tools (hobbing cutter, pinion type cutter) from the database in the tab reference profile. The problem was limited only to the 4th gear. This is now fixed.


SP3 Wrong VHJ approximation for bevel gears with shafts
The bevel gear contact analysis with shafts was approximating wrongly the VHJ misalignment. This is fixed.


SP3 Measurement grid report for fillet surface gives error when using very high number of rows
Measurement grid report for fillet gives an error when using a very high number of rows.
This is now fixed, but it's still recommended to use a reasonable number of rows.

SP3 Load bins and damage accumulation curve not shown in the SN curve graphics
Load bins and damage accumulation curve were not shown in the SN curve graphics in cases when:
*Check both cases and document unfavorable case
and/or
*Check both cases and document the more realistic case
were selected in Tab rating-> Details. This is now fixed.


SP3 Operating pitch line in the meshing graphics
Operating pitch line was not shown in the meshing graphics in case that gear 1 was a worm. The issue is fixed now.


SP3 Problem with gear body deformation of first gear in contact analysis
The gear body deformation of the first gear (input as .resu file) was considered in the wrong Y-direction of the contact analysis. This is fixed.


SP3 Problem with H and J misalignment in bevel contact analysis
The bevel gear contact analysis was calculating the gear offset due to H and J misalignment wrongly. This is fixed.


SP3 Factors ZR and ZV according ISO and DIN
According ISO6336 and DIN3990 for factors ZR and ZV the sigHlim-value of the softer material has to be used. Up to now, the lower sigHlim was used. This corresponds in 99.9% of the cases also with the material having the softer surface. This is now changed, the sigHlim-value of the softer material (in terms of HB, HV or HRC) is used.


SP3 Problem with number of load spectrum bins in modification sizing.
Number of bins of load spectrum was not correct if considered in modification sizing. This is fixed.


SP3 Convert tooth thickness allowance deactivated for globoidal worm wheels
Convert tooth thickness allowance from tooth thickness at reference diameter is now deactivated for globoidal worm wheels. This is affecting the Asn convert button in the Tab Tolerances.


SP3 Radius of curvature of a read-in tooth form consisting of splines
Radius of curvature of a read-in spline tooth form consisting of splines was not displayed correctly for external gears. This is now fixed.


SP3 Conversion from Gleason data not working in special cases
In some special cases, when mean circular thickness was an input, the conversion from Gleason data was not correct for bevel gears. This is now fixed.


SP3 AGMA 6015 check for limitations were not correct

In some cases, the MrK and MdK was not calculated correctly from the tooth form (they were set to 0 or a small value). This is now fixed.


SP3 Profile shift coefficient conversion of master gears was not working
Profile shift coefficient conversion of master gear was not working. This is fixed.


SP3 Rough sizing was ignoring own input of b/mn, and similar, sizing ratios.
The rough sizing of gears was always setting back the ratios, such as b/mn, to predefined ratios defined in tab 'Sizing' of dialog 'Module Specific Settings' in case of 'Area of use for the gear' is set to 'Own input of b/mn, b/a, b/d1'. This is fixed


SP3 The final machining setting was not stored in calculation file
The final machining setting in tab 'Manufacturing' was not stored in calculation file. This is fixed. There was no impact on the results.


SP3 Static root safety factor sigS/sigF in results window for 4 gears
Static root safety factor sigS/sigF was not shown correctly in the results window for the last gear in a 4-gear chain. This is now fixed.


SP3 Sound pressure level according to Masuda
Sound pressure level according to Masuda: In equation 5 of the paper Teruo Masuda, Prediction Method of Gear Noise Considering the lnfluence of the Tooth Flank Finishing Method, the power W in the term '20 log(W)' was used in HP according equation 1 from Kato. But in eq. 5, W should be used in kW. This is now fixed, the dB values acc. Masudo are now a bit lower.


KISSsoft - General

SP3 Toothed belt PG 14mm Power Grip had wrong data for the power
The toothed belt PG 14mm Power Grip HTD from Gates had some wrong data for the power in the Z091-011.dat file.


SP3 Graphic property font size was not restored
For graphics that have a font size property, the value was not stored after a recalculation.


KISSsoft - Graphics

SP3 Wrong order of line load in load distribution graphic of planetary system contact analysis
The "Normal force distribution on Tooth (Line Load)" graphic for planetary contact analysis was showing the planet load in the wrong order. Because of this, the graphic was showing load on planets where no load was.  This is fixed.


SP3 Lineload and gap graphic was showing wrong curve when 'Always calculate transmittable torque (utilization)' option is used
The lineload and gap graphics have been showing 4 curves instead of the one correct line in case of 'Always calculate transmittable torque (utilization)' option is used. In case of load spectrum the lineload and gap graphic is deactivated. This is fixed.


SP3 Empty graphics in bevel gear contact analysis
Graphics capable of showing evaluation (available for e.g. hertzian stress 3D of bevel gear contact analysis) have been empty. This is fixed.


SP3 Pitch point C added to gear pump graphics
The pitch point C was missing in gear pump graphics. This made the gear pump results a bit unclear and is fixed now.


KISSsoft - KISSdesign

SP3 Delete in calculation view versus shaft view
Deleting elements (for example gears) from the calculation view (clicked on the respective gear element, and pressed the “Delete” button on the keyboard) is deleting the gear** from the model. However, only the reference of the given gear to the calculation should be removed.


SP3 Rough sizing did crash on cancel
Canceling the rough sizing did cause a crash in cases where shaft calculation related data had been changed.


SP3 Merging bug in sketcher
Dropping an axis onto a dot did merge the shafts instead of making them coaxial.


SP3 Fix for center distance transfer from KISSdesign rough sizing to gear calculation
The rough sizing data from KISSdesign was not properly transferred to the gear calculation sub module (for ex. center distance). This is now fixed.


SP3 Fix for recurring message when coming back from shaft calculation to KISSdesign
When coming back from shaft calculation to KISSdesign, a message informing the user that elements could not be added directly in the shaft calculation was always popping up if the model had some connection elements. This is now fixed and should only happen when necessary.


SP3 Fix for planetary animation and bearing representation in 3D view
In the 3D view, the initial planet was not rotating, and the planets connection bearings were not properly represented (creating two normal bearings for inner and outer shafts instead of just one connecting bearing). This is now fixed.


SP3 Fix 3D animation of planetary gear sets
The original planet of a planetary gear set was not rotating around the carrier axis in the 3D view, this is now fixed.


KISSsoft - Proof of strength with local stresses

SP3 FKM method, local stress: The roughness value wasn't set correctly
The roughness value Rz wasn't set correctly, the value was always the same.


KISSsoft - Root stress FEM calculation

SP3 3D FEM root stress cannot be calculated when modifications are applied.
The 3D FEM root stress calculation stopped when some modifications were applied. This is fixed.


KISSsoft - Shaft calculation

SP3 Required fatigue safety had no influence in the graphic display of usage

SP3 Distributed mass element in eigenfrequencies calculation.
When a distributed mass element extends over many different geometrical elements, there are cases where the mass is not taken correctly into account.


SP3 Input for load spectrum did not work for bevel gears
The input for the load spectrum of a bevel gear did not work.


SP3 Bearing service life factors report was not shown for connecting bearings
In case of connecting bearings in a shaft calculation, the bearing service life factors report is not shown.


SP3 Bearing factors were shown with wrong unit in bearing service life factors report
Bearing factors X, Y, X0, Y0 were shown with unit N in the bearing service life factors report although indeed non-dimensional.


SP3 Fixed inaccurate formula symbol in the bearing sizing dialog
In the bearing sizing dialog, the bearing rating life was shown as Lh instead of Lnh.


SP3 Added confirm message box to cancel calculations in case a bearing type does not support ISO/TS 16281
In case a model is configured to be calculated using ISO/TS 16281 but some bearing types are not supported in KISSsoft with this calculation method, a confirm message is shown before starting the calculation.


SP3 Exporting general supports to plain journal bearing calculation files was not disabled and failed
As of Release 03-2018, plain journal bearings are a separate element in the shaft calculation. General supports should not be used anymore to model journal
bearings, however exporting them was still listed as an option that however failed on execution. The export of general supports to plain journal bearing calculation files was thus disabled.


KISSsoft - Shaft-hub-connections

SP3 Backlash values in the individual shaft/hub reports
Backlash values in the individual shaft/hub reports didn't make much sense. Instead, the effective jtv and jnv (for the use with gears) values are now shown.


KISSsoft - Splines calculation

SP3 Tolerance fields for Flat Root Side Fit according ANSI B92.1 corrected
Tolerance fields for Flat Root Side Fit according ANSI B92.1 corrected


KISSsys - General

SP3 Windows layout issues in KISSsoft when called from KISSsys
KISSsoft did not show the last windows layout when it was called from KISSsys. Somethimes the W010 element tree was missing or graphic windows where randomly positioned.


SP3 Fix for working pressure angle set in shaft calculation with effective profile shift
In cylindrical gears, when calculating with operating center distance and manufacturing profile shift, the resulting working pressure angle set in the shaft calculation was wrong. This is now fixed.


SP3 Fix for transferred center distance when effective profile shift is set
When the effective profile shift was set in the gear calculation, a wrong center distance was communicated to the system. This is now fixed.


SP3 New button in GEMS interface to calculate the bevel deviations
A new button was added in the GEMS interface template to directly calculate the deviations of the current gear set.


SP3 Fix stepped planetary gear pair churning losses calculation
Stepped planetary gear pair churning losses calculation were not considered properly because there is no real proposition in the ISO TR 14179. We adapted the calculation of standard planetary churning losses to give a more consistent result taking into account carrier rotation.

SP2 The 3D system model of bevel gear had wrong position when saved with H, J, V misalignment
The 3D system model of bevel gear had wrong position when saved with H, J, V misalignment.
This is fixed.


KISSsoft - Bearing calculation

SP2 Pressure angle of FAG thrust angular contact ball bearings
The pressure angle of FAG thrust angular contact ball bearings was 0° instead of 60° in the KISSsoft database.

In the Sub-Window of the 4-gear stage, where double planet stage can be activated, an additional input is available: Now the position of Planet2, if on the right or on the left side of Planet1, can be defined. This affects the 2D and the 3D display.


SP2 Active tip and root diameters in the meshing graphics
The setting for the form diameter calculation (module specific settings) is now considered when calculating/displaying the active tip and root diameters in the meshing graphics (no load condition).


SP2 Bevel Gears according AGMA2003, change to static calculation eliminated
In Bevel Gears according AGMA2003, an automatic change to static calculation happens, if load cycles were lower than 1000 cycles.
This is not wrong but may be confusing, and in AGMA2001 for cylindrical gears we do not do it.
This is now eliminated.


SP2 Improvement: Worm Gear according EDIN3996
Worm Gear according EDIN3996 is available, and last printing errors in the document were discussed, corrected and added in KISSsoft.


SP2 Problem in 'Generate cylindrical gear with the read-in pinion type cutter'
Center distance check was wrong when using the tooth form operation 'Generate cylindrical gear with the read-in pinion type cutter'. The problem only occurred for helical gears. This is now fixed.


SP2 Profile modification on the flank of asymmetric gears changed without warning
In some cases for asymmetric tooth forms, the flank of the profile modification was changed from left to right without warning. This occurred in cases when there was an error in the tooth form calculation. This is now fixed.


SP2 Worm gear, Start under load modified
The calculation of the torque to start under load is not part of the standard, but based on a note in the Niemann book.
The indication in Niemann applies for driving worm. We extrapolated the driving gear case until now, but this is not really approved in practice.
We eliminated now this case and indicate that most probably the set is self-blocking.


SP2 Problem with tooth stiffness calculation in case of force close to root fillet and high pressure angle
In case of gears with high pressure angle and load close to the root fillet, the bending lever of the Weber/Banaschek based contact analysis is negative. In such a case the stiffness calculation was wrong because only hertzian, normal and shearing deflection should be considered. This is fixed.


SP2 Measurement data for worms
Radial single-ball measurement MrK (min and max value) for worms was not calculated. Additionally, measurement data  (except MdK and MdR) for worms was not correct in case if the worm had more than 3 teeth. This is now fixed.


SP2 Nominal transmission ratio in rough sizing overwritten
User defined nominal transmission ratio was overwritten (with initial value) in the rough sizing when the calculation was performed. This is now fixed.


SP2 Asymmetric gears calculation
If creating a "fresh" KISSsoft calculation file, and then converting it to asymmetric gear, the calculation was not working. This is now fixed.


SP2 Tab modifications info text
Tab modifications info text for Helix angle modification (parallel - arc minute) and Pressure angle modification (parallel - arc minute) was not correct. This is now fixed.


SP2 Splines DIN 5482 example
Shaft-hub connection  DIN 5482 40x36 e9_H10 example had the wrong profile shift in the DAT file. This is now fixed.


SP2 Fine sizing of Planetary stages
Added a Message, when Planetary stages with all elements (sun, carrier, ring) rotating are used, to better use the ratio definition with the 'z3/z1 option'.


SP2 Profile modification sizing was calculating same face load factor for different loads
The profile modification sizing dialog was calculating always the same face load factor for different load cases. This is fixed.


SP2 Runout in the operating backlash calculation
Own input of the runout error was not possible in the operating backlash calculation. This is fixed now.


SP2 Absolute speed value for bevel gears with carrier speed in the report
In the rpt template for bevel gears, the absolute speed calculated from the teeth ratio was using the virtual cylindrical number of teeth instead of the real bevel number of teeth. This is now fixed.


SP2 Woehler line display for planets
In some cases, the Woehler line for the planets was not drawn correctly. This is now fixed. It was purely a graphical error, so all the results are unchanged and correct.


SP2 Path of contact in the meshing graphics (for worms)
Path of contact in the meshing graphics was not drawn to the base diameter of the worm. This is now fixed.


SP2 Wrong face load factor due to inconsistent shaft calculation
In some cases the face load factor and its respective line load was calculated wrongly because the shaft calculation wasn't consistent after calculating the shaft bending line. This is fixed.


SP2 Estimation of collision between tool shaft and gear for the power skiving checks improved
In addition to checking for collisions between the tool shaft and gear when power skiving, the critical inner offset length, that an inner gear can be manufactured at, is calculated and displayed in the report.


SP2 Modification sizing for bevel gears
Headers in the modification sizing dialogue (tab results) for bevel gears was not shown correctly. This is now fixed.


SP2 Bending of the shaft and flank line modifications in the operating backlash calculation
Option 'Take into account the bending of the shaft and flank line corrections' was not considered correctly in the operating backlash calculation. This was limited to special cases, when load spectrum with more than 1 bin was defined, but 'Don't consider load spectrum' or 'Only take 1 bin into account' was selected in tab Rating. This is fixed now.


SP2 Grinding notch factor calculation for internal gears using form grinding
In special case, the grinding notch for the internal gear was not calculated correctly. This only appeared for the form grinded gear, using VDI 2737 for the form factors calculation. The issue is fixed now.


SP2 Alternating bending factor according ISO6336-3, annex B, for plastic materials
ISO6336-3, annex B, is only applicable to metals. For plastic materials the Mean stress ratio is approximated. We added now a warning message, if plastic gears are calculated.


SP2 Conical expansion of internal gears was considered wrongly
The face load factor calculation according to ISO 6336-1, Annex E, and the contact analysis was considering the conical expansion of the internal gear, due to load, wrongly. This is fixed.


SP2 Generate cylindrical gear with read-in pinion type cutter
In some special cases, the generated cylindrical gear with a read-in pinion type cutter was not correct. This is now fixed.


SP2 Power skiving check result was sometimes not correctly listed in the fine sizing
Sometimes the result of a power skiving check in the gear fine sizing was listed as "not checked" instead of "not possible".


SP2 Uploading load spectrum from file did not set the inconsistent flag
The inconsistent flag was not set when a load spectrum has been read in from a file in tab rating.


SP2 Wrong speed in results table of contact analysis in some cases
The speed documented in the results table of contact analysis was wrong in case of a speed < 1m/s. This is fixed.


SP2 Number of digits increased in tool export rps report
Number of digits increased in tool export rps report from 3 to 8.


SP2 Report of Duty cycles
Improvement: The Duty cycle definition in the report is changed into table format.


SP2 3D model not correct

Supported keys are B (bearing), R (carrier), S (switch), C (coupling), G (cylindrical gear), V (bevel gear).


SP2 Crash in REXS import fixed
The REXS import crashed in case existing elements should be overwritten.


SP2 Improvement: extended drag-and-drop in KISSdesign sketcher
- Possibility to connect planetary stages and gear chains directly in the sketcher by drag-and-drop added
- Merging shaft calculations in sketcher by drag-and-drop one axis on the other added
- Moving one shaft to another shaft calculation by drag-and-drop added


SP2 Improvement: visual feedback for drag-and-drop in trees
Dragging elements in the trees gives a visual feedback if dopping will be possible or not.


SP2 KISSdesign sketcher graphical issues
It was not possible to select connections if they were directly sitting over an axis.


KISSsoft - Shaft calculation

SP2 Bearing rating life for non-rotating but loaded bearings was infinity
For non-rotating but loaded bearings, the corresponding bearing rating life resulted in infinity. This was fixed and for such cases the bearing rating life is now set to 1e10 h.


SP2 Automatically setting critical cross sections sometimes caused misleading results
In some cases, the functionality to automatically set the critical cross sections of a shaft resulted in cross sections with wrong positions.


SP2 Missing low eigenfrequencies
In some very few shaft examples a low (normally below 10Hz) eigenfrequency was missing.


SP2 Drawing for angular contact thrust ball bearings in shaft editor
All angular contact thrust ball bearings in the KISSsoft database have a pressure angle at the order of 60°. The drawing did not reflect this fact.


SP2 For larger groove width diameters, the notch factors for the shaft strength calculation are not considered correctly
In some models that had larger groove width diameters, parts of the surrounding shaft section were also considered as groove instead of just a smooth shaft section.


SP2 Crash in element tree fixed
KISSsoft crashes when removing notch elements of a shaft and adding another cylinder afterwards via context menu. This is fixed.


KISSsoft - Shaft-hub-connections

SP2 Radial bearing stiffness was not properly calculated in some cases
