Furthermore, it is currently possible to consider the load and speed direction of each element separately. For the flank calculation, optionally just positive load elements can be considered. For the root calculation, the alternating bending factor is considered with 0.7.
Finally, the load spectra calculation is also available for beveloid gears.
The calculation of load spectra in KISSsys (module SYS or GPK) can now be performed for several kinematics in one step. The values of the load elements are shown in an additional table.
In the upcoming KISSsoft version 03/2015 which is released at the industrial fair in Hanover in April, additional detailed information about damage calculation of gears, shafts and bearings are available. Keep on being curious and visit us at the HANNOVER MESSE 2015 in hall 25 at booth H18!

Additionally, a new dialog is available which allows the user to define the number of slices for the calculation of load distribution. This allows, among other things, a faster calculation for planetary gears.
Based on the effective gaping in the tooth mesh, the optimal flank modification is now delivered. The flank line modification is considering the bending and torsion components of the shaft deformation.
Finally, the sizing of lengthwise crowning and helix angle modification is currently possible under consideration of the axis misalignments. The modification values are therefore calculated using the exact method ISO 6336-1, Annex E.

In the graphic presentations, the location of the calculated strength cross sections is displayed in the graphic 'Strength'. A new graphic under 'Shaft/3D Display/Deformation (Bending)' also illustrates the bending lines and shaft forces in 3D.
In the upcoming KISSsoft Release 03/2015, these highlights of the shaft calculation have been expanded even further: If you want to get to know them and are interested in the beta version, please send us an e-mail and we will send you a trial license back. We look forward to receiving your feedback!

With the "Efficiency Template", available for KISSsys, the efficiency calculation and thermal analysis in accordance with ISO/TR 14179 are carried out for all types of transmissions and drive trains. In addition, the template now includes a large number of new functionalities, which meet the requirements of the industry.
With the integrated programming language in KISSsys, own modifications of the calculation code can be made. Improvements of the gear design and the required cooler power are therefore much more purposefully and easily definable by the user.
If you are interested in a trial version or in a detailed manual, just contact us – or visit our booth K09 at the CTI Automotive Transmission Symposium in Berlin from the 8th until 11th of December 2014.

Furthermore, CADFEM developed together with KISSsoft in ANSYS the tool "WB/Bolt Assessment under VDI2230" for automated evaluation of bolts, so complex component part geometries can be calculated efficiently. The benefit of this tool is the fast and reliable assessment of large housing structures with many bolts. Consequently, the user is freed from tedious, repetitive tasks and can concentrate on the development of optimal and reliable gear boxes.

The usual flank modifications, such as helix angle modification or negative crowning, are still available to help optimize tooth contact in a 3D model.
Finally, tooth contact can be verified using the graphical contact analysis method, and the models can be exported for various purposes, such as FE analysis, 5-axis milling, or output to a measurement grid.

Unlike when you are working in some other calculation or software programs, you can change the user interface language in the KISSsoft system even when you are right in the middle of the calculation process. In addition, we have built up technically strong representative offices in numerous countries around the globe to guarantee support in the local language (in Mexico, Brazil, the USA, France, Turkey, Russia, People's Republic of China, South Korea, India, etc.).
The ease with which you can change the user interface language and generate reports and graphics in other languages makes it possible to:
- outsource engineering or production – calculation files, reports, results and data exports can be created, opened and edited in any language (no additional translation costs).
- perform benchmarking and integrate components from several companies (as it is typical in the wind turbine manufacturing sector, automobile construction, etc.) across multiple countries and languages.

Instruction 092 „Modifying Reports“ assists the user to design custom report templates. Thereby unit adjustments and font size, settings in graphics as well as tables belong to the comfortable handling that KISSsoft provides.
It is now also possible to extend the configuration of the software. So the result display can be customized individually. With the Instruction 093 ”Define Rules”, the user is able to create custom rules for implementing e.g. internal company standards. The user also can be notified of intermediate values or results which are outside of permissible limits.
Do not hesitate to contact us if you have any questions!

The VDI Guideline 2545, the predecessor of the VDI 2736, has already been implemented in the 80’s in the calculation program of KISSsoft. Nowadays, plastic gears are found in many transmissions, but the VDI guideline 2545 was withdrawn. For this reason, we welcomed it very much to participate in the Guideline VDI 2736.
We are delighted that KISSsoft could bring own insights from everyday practice into this development process.

These graphics can also be animated to illustrate rotation and bending, making even the most complex shaft systems easy to display and to understand.
Furthermore, the shaft calculation was reprogrammed in its calculation core. This not only improves stability considering calculation convergence, but also makes errors easier to identify and resolve.
Wednesday, 04. June 2014
The calculation programs of KISSsoft are based on the implementation of all relevant standards and their drafts (ISO, DIN, AGMA, VDI, Klingelnberg). This allows KISSsoft to be always on the cutting edge of technology and to offer many design and optimization tools, as well as methods which transcend the standards.

Workgroup 6, chaired by Professor Höhn, is intensively engaged in the development of a Technical Report, in which for the first time eight examples of calculations according to ISO 6336 will be documented. This work is very important for KISSsoft, because it can demonstrate that our software correctly implements the ISO 6336 and we get the same results, as they will be published in the standard.
After concluding the new issue of the ISO 1328-1 for cylindrical gear tolerances, Workgroup 2 works now on the Technical Report 10064: Code of inspection practice. The ISO 1328-1 was published in 2013 and is included in the new KISSsoft Release 03/2014. Since the differences compared to 1995 are considerable, both versions of Part 1 are now available in KISSsoft. We assume that it will take still much time until the new tolerance values are generally considered.
Workgroup 7, chaired by Dr. Octrue, is concerned with the geometry and strength of worm wheels. The different flank forms of the ISO TR 10828 are implemented in the 3D worm models of KISSsoft.
We are pleased to have hosted these successful meetings full of inspiration!

For many years it has been possible to design custom report templates. In addition, unit adjustments and font size, settings in graphics as well as tables belong to the convenient customization capabilities that KISSsoft provides.
In the Release 03/2013, some interesting new possibilities are available which extend the configuration of the software. So, the result display can be customized individually. Furthermore, the user can create custom rules to implement, for example, internal company standards. The user also can be notified of intermediate values or results which are outside of permissible limits.

The shaft calculation standard DIN 743:2012 contains now the proof in order to avoid incipient cracks on hard surface layers. Furthermore, calculation with load spectra according to the method "Miner extended" and slight modifications of the technological size influence coefficient K1 are available.
The 6th Edition of the FKM guideline implies currently some changes considering the material data and the calculation of the support factor number according to the material-mechanical concept.
Comparisons to the previous edition of the two standards were performed by KISSsoft and are available on request.

The "KISSsys assistants" (for parallel shafts and for single stage planetary gear units) guide the user through the steps involved in modeling a parallel or planetary gear unit.
Since the Release 2013, in the user interface, the most commonly used elements are now available as icons. To generate a model a user can simply drag and drop icons to add elements directly to the diagram window and link them to each other together.
Furthermore, the „Gearbox variant generator“ completes KISSsys with an efficient method for automatically creating numerous variants of gearboxes. The evaluation function enables you to make quick comparisons based on space, cost, efficiency and other criteria.
As we celebrate this year 15 years of KISSsys, we host a competition: The best application will win the KISSsys AWARD 2014!
Submit a KISSsys model and convince our jury. We are looking forward to your participation!

KISSsoft evaluates the wear according to the calculation of Plewe (module ZPK) and in the contact analysis with local numerical values (module ZA32).
Furthermore, the influence of the lubricant is considered in KISSsoft. The KISSsoft calculations were compared with the damage course of the test bench and show a very good agreement. This comparison confirms this practical calculation method.
If you are interested in further information, please contact us at: info@KISSsoft.AG

We recently performed rolling tests of the milled bevel gear and worm gear sets and compared the contact patterns with the predicted results from KISSsoft contact analysis: KISSsoft contact analysis results matched the actual contact pattern.
We are pleased to give a lecture on this topic at the Dresden Machine Elements Colloquium (DMK 2013) in Germany. Find more information about events and fairs on our website.
Wednesday, 09. October 2013
Experience gained from a comparison between various commercial contact analysis programs, carried out in fall 2012, has also left its mark on the calculation.
For example, additional correction factors (including one for Hertzian flattening) have been implemented, providing the user with even more detailed setting options. Of course, appropriate standard values are also set where suitable.

The KISSsoft fine sizing is applied to gear optimizations of all kinds - from static strength to noise optimization. Thereby, the macro geometry is varied in desired areas and the optimal solution according to various criteria is selected from the calculated variants. Plastic helical gears can be directly calculated according to the new draft of the VDI 2736.
After the cylindrical and bevel gears, these fine sizing modules complete the sizing process for all toothings.

At the same time, graphic position and scale can be set by the user on his own. Now toothing data can be easily arranged and placed on the graphic.
The settings are saved in a separate file and thereby adopted for all gears. This approach favors also the definition of company standards.
Have a look at the manufacturing drawing examples in a KISSsoft test license.

A new feature is that the face load factor KHβ can now also be calculated. This therefore reveals the direct influence of the tooth trace modification on the safeties of the classic tooth root and flank load capacities.
Modifications are evaluated in the radar chart, which also provides a very clear comparison, especially within different partial loads.
Wednesday, 26. June 2013
New dimensioning suggestions are now calculated for modifications, especially for planetary gear units (module ZA5). This ensures that tooth trace modifications can be specified accurately, on the basis of the planet carrier torsion and sun gear deformation.
Thursday, 13. June 2013
The already existing "Parallel Shaft Assistant" can now – along with spur and helical gear
stages – also create bevel, worm and crossed helical gear stages. The modeling process itself is also made more intuitive, the user is guided step by step through the entire gear box structure.
New: The "Planetary Gear Stage Assistant" is implemented. The user is guided explicitly step by step through the kinematic structure. From the sun to the planet carrier - no element is left out, the modeling process is accomplished directly with coaxial shafts.
Following the modeling, the rough sizing of the gears can be carried out in KISSsys. This feature is available for cylindrical and bevel, worm and crossed helical gears as well as planetary gear units.
Thursday, 13. June 2013
The VDI 2736 covers plastic gears and is replacing the withdrawn guideline VDI 2545. Newly added are steel worms paired with plastic gears, for which a safety against root shear stress and the flank pressure are calculated. Considering cylindrical gears now also the wear is determined. Part 2 (load capacity of cylindrical gears) and part 3 (load capacity of worm gears) are already published as official drafts. Part 1 (materials and manufacturing) and part 4 (conducting and analyzing of material measurements) should be available at the end of this year or early next year.
We are pleased to have hosted this successful meeting full of impulses!

The basis for the load distribution calculation of cylindrical gears is the shaft deformation. While Part 1 of the ISO Norm 6336 does provide only rough classifications for shaft deflection, the Annex E allows to specify the exact value - manually or in KISSsys. The accurate determination of the load distribution forms the basis for an appropriate tooth correction.
In the advanced training courses of KISSsoft tooth corrections are covered extensively.
