The gear calculation in KISSsoft covers all common gear types such as cylindrical, bevel, hypoid, worm, beveloid, crown, and crossed helical gears.

In the KISSsoft release 2021, new graphics for the crossed helical gear calculation are available. The evaluation graphic for specific sliding is calculated and displayed based on the geometry of a spur replacement cylindrical gear. A visual evaluation of the tooth meshing in 2D is now also possible for axis crossing angles not equal to 90°. For this purpose, parallel sections to the center axis plane of the worm are calculated and shown. This 2D geometry is visualized using the “tooth meshing in slices” function. The option “determine form diameter dFf and dFa from tooth form” is also selectable.

With the help of the fine sizing method in KISSsoft, users can also find the best variants for crossed helical gear stages with preset, definable boundary conditions. If you input the nominal ratio, normal module, pressure angle, helix angle, center distance, and profile shift coefficient, the system calculates and displays all the possible suggestions.

All the variants the system finds are then output in a list, classified by the most varied criteria (accuracy of ratio, contact ratio, safety factors, weight, axial forces etc.). Users can either expand or reduce the scope of the list if they want to display more or fewer individual results for a specific solution.
