Title:
ROBOT POWER TRANSMISSION MECHANISM FOR TRANSMITTING ROTATIONAL FORCE AND ROBOT DRIVE UNIT
Document Type and Number:
WIPO Patent Application WO/2024/013888
Kind Code:
A1
Abstract:
A robot power transmission mechanism according to the present invention is provided with a strain wave gearing reducer including: a wave generating member including an elliptical cam; an elastic cylindrical member having first teeth; and an annular member having second teeth that mesh with the first teeth. A shaft that transmits the rotational force of an electric motor has a spline shaft part having protrusions formed on the outer circumferential surface thereof. The wave generating member includes insertion holes having a recessed shape corresponding to the shape of the protrusions of the spline shaft part. Between the spline shaft part and the insertion holes, there is a gap having a size sufficient to allow the wave generating member to align through movement made possible by the elasticity of the elastic cylindrical member.
