KISSsoft - 3D geometry (STEP interface)
SP1 Skin model for single tooth cylindrical gears
For cylindrical gears with only one tooth, the skin model is generated correctly now.
SP1 Cylindrical 3D gears with skin model
In the 3D gear geometry for cylindrical gear, the root was missing when displaying it as a skin model.
KISSsoft - Bearing calculation
SP1 Bearing damage for bearings with 0 speed
For bearings with zero speed, both the lifetime and the damage were documented as infinite (L = 10^6 and damage = 9999.99 respectively). This was wrong, and the damage should NOT be printed as infinite, but rather very small (eg. 1%, depending on the required lifetime).
KISSsoft - Gear calculation
SP1 Improvement: Measurement over 2 pins acc. to AGMA 2002-Cxx
Measurement over 2 pins (free and transverse) acc. to the proposed revision of AGMA 2002-Cxx are added for cylindrical gears.
SP1 Tab reference profile: Inner gears
In the user interface for the tab reference profile, the conversion to diameter for internal gears was wrong, when the option to display internal gears with positive diameters was chosen (definition according to ISO instead of DIN).
SP1 Conversion of addendum coefficient of gear for non-topping hobbing cutter
In the user interface, the conversion of addendum coefficient of gear for a non-topping hobbing cutter was not working properly.
SP1 Tooth thickness at reference line
The input of the tooth thickness at reference line for hobbing cutter was not visible and therefore couldn't be changed.
SP1 Center distance tolerance for gears (own input)
The user input for center distance tolerance of gears (excluding gear pair) was not working properly, when the tolerance was set to "Own input".
SP1 Fine sizing of planetary gear with contact analysis
"With calculation of the transmission error" option in the fine sizing
of planetary gears was not working and giving no results.
Now the problem is fixed.
SP1 Topological modification for internal gear
The topological modification for internal gear was not working correctly
caused by the wrong assignment of the tooth length factor.
The problem is fixed now.
SP1 Wrong equivalent H and J deviation in bevel gear contact analysis.
In cases of bevel gear tip is pointing to the negative y direction on a shaft, the bevel gear contact analysis was calculating a wrong equivalent H and J deviation. This is fixed now.
SP1 Grinding notch effect with internal gears
For internal gears, when grinded, the addendum hGrind of the pinion like grinding tool is now calculated and documented.
This value is now used to calculate more precisely the grinding notch factor Ysg.
SP1 Wrong sign of V deviation in bevel gear calculation
The sign of the V deviation in bevel gear contact analysis and 3D-System was wrong. Additionally the G deviation was renamed into J deviation according to Klingelnberg and the respecting info image was extended.
SP1 Sense of rotation error message for bevel gear contact analysis
The bevel gear contact analysis with shafts showed an error regarding the sense of rotation in case that one of the shafts has a bevel gear with tip pointing to the left (coordinate center point). This is fixed.
SP1 Linear tip and root relief with transition radii
2 additional cases considered: If Factor 2 is 0, then transition radius r is calculated so that LI = 0.8Lca. If Factor 2 is so big, that LI< 0.5LCa, then transition radius r is calculated so that LI = 0.5Lca.
SP1 AGMA 925 calculation for planetary gear
The load distribution factor Kγ was not considered in the AGMA 925 calculation.
Now the problem is fixed.
SP1 Planet Carrier deformation : Wrong distance between node I and II for calculation of double sided carriers
The proportional "Tilting of bolt relative to planet carrier axis" (drp, dtp) at dialog "Define axis alignment" was calculated with the wrong distance between node I and II for double sided carriers using Code_Aster.
SP1 Improvement: Excel-Sheet for Topological Modifications
Topological Modifications are defined in dat-files. We added in the \dat folder an Excel-Sheet 'Topological Crowning.xlsx' to produce the table with the definition of the modification. The sheet includes also an example how to define a negative profile crowning.
SP1 Ramp angle on hobbing cutter with pre-manufacturing
In some cases, the ramp angle was set to 0, when a hobbing cutter and pre-manufacturing was chosen.
KISSsoft - General
SP1 Improvements in KISSsys 3D viewer
Various improvements of the 3D viewer for KISSsys (eg. the placement of the shafts was not correct if the shaft orientation was complex).
SP1 ALL TOPICS mentioned in PATCH G of 2015 ARE ALSO PART OF THIS PATCH, but not mentioned anymore
Please consult on our website the list of topics for Patch G (7) of 2015.
KISSsoft - Graphics
SP1 Improvement on manufacturing drawing
For the manufacturing drawing, there is a new command to keep a fixed scale of a graphic.
With the command fixedscale 1, it's possible to have the
drawing 1:1. The window command afterwards specifies the x,y-values
for the topleft corner of the drawing.
window: 270, 297
KISSsoft - Pin calculation
SP1 Spiral spring pin: Admissible shear stresses for spring pins
The admissible shear stress τbmin values from the standard (f.e. DIN EN ISO 8748) for the spiral spring pin are for the double shear cases.
In single shear case can be used only half of the values from the standard. This was documented in older standards (f.e. DIN 1481:1978).
KISSsoft - Shaft calculation
SP1 Crash due to the eigenfrequency calculation of complex shafts.
Sometimes the eigenfrequency analysis of complex shafts or big shaft systems could result in a crash of the software. This is now fixed.
SP1 Wrong sign while considering gear body deformation in shaft calculation.
The tooth trace modification of the shaft calculation did consider the influence matrix for additional gear body deformation with the wrong sign. This is fixed.
KISSsoft – Gear body FEM calculation
SP1 Unsymmetric gear body influence matrix.
The influence matrix generated for an unsymmetric gear body using FEM calculation had an error.
KISSsoft – Planet carrier FEM calculation
SP1 Planet carrier FEM calculation using step file
There was a problem starting the FEM calculation of a planet carrier, using the geometry from a step file.
KISSsys - General
SP1 Inclusion of housing stiffness without FEM initial offsets.
In the case the imported stiffness matrix did not include any FEM initial offsets, the calculation was returning an error.
SP1 Reading of ABAQUS reduced stiffness matrix with 4 master nodes.
Sometimes there was an error reading an ABAQUS reduced stiffness matrix with 4 master nodes. The matrix was not read and the calculation could not proceed further.
SP1 Gear modification information in the ExportSystemData function.
Added gear modification information in the ExportSystemData function.
