Method for determining tooth deformations, preferably for static transmission error of gears

摘要

A method for determining the deformation of loaded teeth (1, 2) of a gear (A, B) has been realized after checking that the point of contact (E), in which the force transmitted under load is concentrated, moves and distances itself from the contact line (L) due to the deformation of teeth. In particular, for each angular position of the meshing wheels, an iterative process identifies the contact point as a result of the deformation since at each new position of the load, the relative deformation must be recalculated up to convergence because it depends on the position of the load. The method allows in particular the determination of the static transmission error (STE), of modified tooth profiles to minimize the STE and the realization of the relative toothed wheels.
