Title:
DIFFERENTIAL DECELERATOR
Document Type and Number:
Japanese Patent JP2020133694
Kind Code:
A
Abstract:
To provide a differential decelerator capable of improving rotation balance of an input shaft without reducing an outer diameter capable of being substantially used as a hollow hole.SOLUTION: A differential decelerator comprises: an internal gear 4; an input shaft 6 that is arranged coaxially with the internal gear 4 so as to penetrate through the internal gear 4, and has a through hole 51 centered on its own central axis C0 and an eccentric part 22 eccentric with respect to the central axis C0; and an external gear 3 that is externally mounted on the eccentric part 22, and is inscribed in and meshes with the internal gear 4, in which on the eccentric direction side of the eccentric part 22 on an inner peripheral surface 52 of the through hole 51, a thinned part 53 is formed. Since the through hole 51 is coaxial with the central axis C0 of the input shaft 6 and the thinned part 53 is formed, the rotation balance of the input shaft 6 can be improved without reducing an outer diameter that can be substantially used as a hollow hole.SELECTED DRAWING: Figure 1
