Problems solved by technology

Previous studies have not considered the influence of cycloidal wheel tooth profile modification on cycloidal wheel contact stress. After the cycloidal wheel is modified, the contact stress of the tooth surface will increase, which will reduce the load-carrying capacity of the RV reducer. The structure of the RV reducer It is Necessary to Consider the Modification of Cycloid Gear Tooth Profile in Optimal Design

Embodiment Construction

[0069] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0070] The RV reducer consists of two parts: an involute cylindrical gear planetary transmission mechanism and a cycloidal pinwheel transmission mechanism. 6. Pin gear housing 7 and supporting flange 8; the multi-objective optimization method of RV reducer based on cycloid tooth profile modification is as follows:

[0071] The volume V of the RV reducer is the cycloid wheel V 1 , pin wheel V 2 and spur gear volume V 3 the sum of

[0072] V=V 1 +V 2 +V 3 (1)

[0073] Among them, the volume of the cycloidal wheel is divided into the volume of the root circle plus the volume of the teeth, the pin wheel is a cylinder, and the volume of the cylindrical gear is approximately regarded as the volume of a cylinder whose diameter is the pitch circle, then
