Problems solved by technology

[0006] Flexural mesh gears have problems in that if the weight of the vibrating body is large, the inertia of the vibrating body increases, so a large starting torque is required, and the responsiveness at the time of changing the rotational speed decreases
However, in the wave plug of Patent Document 1, the metal member occupies one end to the other end in the axial direction, so that sufficient weight reduction cannot be achieved.

Abstract

An object of the present invention is to achieve further weight reduction and lower inertia of a flexural meshing gear device. The flex meshing gear device (1) has: a vibrating body (10); an external gear (21), which is deflected and deformed by the vibrating body; an internal gear (22, 23), which meshes with the external gear; and a vibrating body The bearing (30) is arranged between the vibrating body and the external gear. Moreover, the outer peripheral surface of the vibrating body (10) constitutes the rolling surface on which the rolling body (31) of the vibrating body bearing rolls, and the vibrating body (10) is formed by placing the resin component (j) and the metal component (m) in the axial direction. It is constructed by being connected, and the metal member (m) is arranged on the rolling surface.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2017-183119 filed on September 25, 2017. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The present invention relates to a flexural meshing gear unit. Background technique [0003] In the past, there has been a flexural meshing gear device, which has: a vibrating body; an external gear that is deflected and deformed by the vibrating body; an internal gear that meshes with the external gear; and a vibrating body bearing arranged between the vibrating body and the outer gear. between the gears. [0004] Patent Document 1 discloses a wave gear device having a wave plug of a wave generator. The wave plug includes: an outer hollow body made of metal, the outer hollow body made of metal forms an outer peripheral surface of the wave plug; an inner hollow body made of metal, the inner hollow body made of metal forms an inner peripheral s...
