How It's Done

GEARFOX Software logo

GEARFOX Calculation Software

MS-Graessner's own, internet-based software - GEARFOX - enables the calculation of the entire drivetrain. This begins with the analysis of the customer's needs, includes the definition of the product requirements, the calculation of applications, as well as the gear design and culminates in an iterative gearbox optimization.

KISSsoft Software

The KISSsoft software calculates, designs and optimizes the gearbox components. Among others, the following parameters are taken into account: forces/torques, bending stress, strength, mass, stiffness, tension/pressure, transverse/axial forces and Hertzian stress.

Gleason software logo

Gleason Software

Gleason software optimizes the design of individual components. It covers tooth dimensions, gear tooth load and meshing forces. It also deals with tooth contact analysis, the outline of the contact geometry, as well as an extended calculation method of the tooth contact. The finite element analysis enables the calculation of the contact pattern under load and also provides information about the tooth base bending stress, surface pressure, the Wöhler curve and much more. All designs and simulations are also carried out using special CAD software.
