GearEngineer is a special gear software that calculates the exact and real 3D tooth form geometries of cylindrical and bevel gears. The 3D tooth forms are generated using mathematical simulations of the manufacturing process. Micro geometries, i.e. profile and flank modifications, are also taken into account when generating the 3D data. This makes GearEngineer the ideal starting point for 5-axis milling of gears.
With the new version, the GearEngineer is now 64bit and adapted for WIN 10. At the same time, the internal CAD core has been updated and, in addition to the surface and curve output, provides even more stable 3D solid models for special functionalities such as the circumferential chamfer for cylindrical gears. The definition of the tool basic rack tooth profile for hobs has been supplemented by the new tip form "Full radius" in addition to the tip form "Radius with straight line". This means that cylindrical gears with a full root fillet can be calculated and manufactured.
For cylindrical gears, the VDI 2736 standard for plastic gears was added to the load capacity methods according to DIN 3990, ISO 6336 and ANSI/AGMA 2001. In addition, plastics have also been included in the material database. Another new feature is the possibility to calculate with a "wrong" center distance for cylindrical gear pairs. A corresponding function has been integrated for this purpose when designing the profile shift coefficients.
Furthermore, the module for straight and helical bevel gears has been extended by profile modifications in addition to the already existing flank modifications. Thus, profile crowning and tip relief as well as pressure angle modifications are now available for each flank.
The new "duplex" bevel shape is now supported, which results in a constant tooth root along the facewidth. This enhancement, together with the profile modifications, was added in response to user requests from the differential bevel gear forging sector.
In addition to the output options of CAD data in STEP and IGES format, so-called nominal measurement data, are also possible. An updated version of the Klingelnberg´s KIMoS software format has been integrated here, which allows the measurement of the flank topography on corresponding gear measuring centers or 3D coordinate measuring machines.
AGMA's Motion + Power Technology Expo 2021 takes place September 14-16 at America's Center, St. Louis, MO. Join many of the gear and power transmission vendors and customers face-to-face this fall here.
