WAVE GENERATOR FOR A HARMONIC DRIVE

摘要

The invention relates to a wave generator for a harmonic drive, which wave generator comprises a wave ring, which is provided with an elliptical outer contour, and a rolling bearing which is attached to the wave ring and has rolling bodies, which wave generator is characterized in that a rolling body raceway for the rolling bodies is formed in the manner of a channel into an outer peripheral surface of the wave ring. The invention also relates to a wave generator for a harmonic drive, which wave generator comprises a wave ring, which is provided with an elliptical outer contour, and a rolling bearing which is attached to the wave ring and has rolling bodies, wherein the rolling bodies are held in each case in rolling body pockets of an annular rolling body cage, which wave generator is characterized in that at least one rolling body pocket is formed in the manner of a rolling body securing pocket which at least partially engages in both axial directions of the wave ring behind the rolling body which is held in said rolling body securing pocket.
