TEETH GEOMETRY OPTIMIZATION OF THE WAVE TOOTH GEAR LEXspline

B.M. Dnistryan, S.I. Pshenichnyh

The article deals with changing of flexspline tooth geometry of unloaded wave tooth gear and its displacements are considered. Due to incomplete filling of backlashes uneven teeth contact and non-uniform force distribution are appeared in gear pair. Wave tooth gear with the account of the tooth length warps under deformation of a flexspline is considered. Recommendations to reduce the wave tooth gear weight and size taking into account of profiling of flexspline teeth are offered.

Key words: the wave gear, tooth length warps, teeth displacements, gear backlashes, tooth geometry.
