Title:

SPEED REDUCER OR SPEED INCREASER

Document Type and Number:

WIPO Patent Application WO/2016/140234

Kind Code:

A1

Abstract:

[Problem] To provide a speed reducer or speed increaser for which rotational stiffness can be increased. [Solution] This speed reducer or speed increaser comprises: a housing 1; a first crown gear 11; a support 14 that is disposed outside of the first crown gear 11 in the radial direction and supports the first crown gear 11 so that undulating motion is allowed but rotation is not allowed with respect to the housing 1; a second crown gear 12 that can rotate with respect to the housing 1, has a different number of teeth than the first crown gear 11, and faces the first crown gear 11; and a cam 5 that causes the first crown gear 11 to be inclined with respect to the second crown gear 12 so that the first crown gear 11 meshes with the second crown gear 12 and causes the first crown gear 11 to undulate so that the meshing location is moved.
