Problems solved by technology

The second method is to complete the finishing of the installation position of the support bearing in a process after the two support discs are fixedly connected. This method can effectively ensure the machining accuracy of the installation position of the support bearing. In addition, there is also a way to integrate the bearing raceway (ball bearing) into the Two supporting discs, the structure of in

Abstract

The invention discloses a simple supporting mechanism provided with two discs. The simple supporting mechanism comprises an inner gear, the left supporting disc and the right supporting disc, wherein the left supporting disc and the right supporting disc are arranged in a center hole of the inner gear and coaxially and fixedly connected. A left supporting bearing and a right supporting bearing are arranged between the left supporting disc and the center hole of the inner gear ring and between the right supporting disc and the center hole of the inner gear ring respectively. A roller of the left supporting bearing and a roller of the right supporting bearing are directly matched with the inner wall of the center hole of the inner gear. The simple supporting mechanism provided with the two discs can bear a large bending moment and a large axial load, the requirement of a precise speed reducer is met, the machining difficulty is lowered, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of design and processing of an output support mechanism of a planetary reducer with small tooth difference, in particular to a double-disc simply supported output mechanism and a processing method thereof. Background technique [0002] The small tooth difference planetary reducer has a compact structure, stable transmission, and a wide range of single-stage transmission ratios. The characteristics of the multi-tooth contact of the meshing pair make this type of reducer have a large load-carrying capacity. At the same time, the error homogenization effect caused by the multi-tooth contact of the meshing pair It is guaranteed that this type of reducer is more conducive to realizing the effect of precision transmission. Therefore, planetary reducers with small tooth difference are widely used in industrial robot joint drive systems, aerospace, CNC machine tools, national defense weapons and equipment, industrial...
