Abstract

Crossed helical gears with steel worms and sintered steel wheels are widely used in motor vehicles and household appliances. Besides the experimental study of a prototype transmission, the simulation using the finite element method (FEM) is another possibility to test gears under load in the design phase and to optimize them. As part of this paper, a piece of software was developed that enables calculation of wear-related variables, such as the Hertzian stress σH, the minimum lubrication film thickness hmin and the glide path sg, for every single point of the contact between worm and worm gear.
