Problems solved by technology

The reducer has the following disadvantages: the arc radius of the cycloid arc tooth surface should be larger than the radius of the steel ball to eliminate the meshing gap, and when the arc tooth surface is processed with a spherical tool, only the cycloid of a certain section can be guaranteed to be the theoretical value Therefore, accurate meshing transmission cannot be guaranteed, which affects the accuracy of the transmission; to obtain a closely spaced steel ball gear, the accuracy of the diameter and circumference of the steel balls is very high, and even contact deformation must be taken into account, making it difficult to manufacture; steel balls and pendulums Linear arc gears are in point contact with low load capacity

Abstract

A conical cycloid wheel planet transmission means related to a differential teeth planetary reduction gear, the conical cycloid planet wheel is positioned in the main body and mounted in the bearing at the center of the eccentric shaft, forming a conical cycloid wheel planet engagement pair with the conical internal gears having the same cone angle, and forming a gap eliminating output device with the output components. The transmission gear according to the invention has zero transmission error and zero return difference feature, and greater load-bearing capacity.

Description

Technical field: [0001] The invention relates to a planetary reducer with small tooth difference, which is a precision transmission and power transmission device. Background technique: [0002] On November 21, 1997, Hangzhou Electronic Industry Institute submitted an application for an invention patent to the State Intellectual Property Office with the "Cycloid Ball Planetary Reducer", the application number is 97123214.8, and it was granted the invention patent on January 10, 2001. The device includes a main body, that is, an end cover, a right support fixed on the right end of the main body, that is, a housing, a pre-tensioning member located at the right end of the right support, and the left end of the eccentric shaft equipped with a balance weight is supported by a bearing installed in the through hole at the left end of the main body. , the right end is supported by a bearing installed in the blind hole at the left end of the output member, and the output member is sup...
