Problems solved by technology

However, during the relative movement of the above-mentioned planetary gasket with the planetary carrier and the planetary wheel, since there is no anti-rotation measure and the wear resistance of the material needs to be improved, the planetary gasket is easy to wear and generates relatively large noise.
When the amount of wear of the planetary gasket reaches a certain level, the planetary wheel is prone to serious partial load, which eventually leads to a greater risk of the power split system - the planetary row assembly

Abstract

The invention provides a planetary spacer, comprising a body, the overall cross section of the body is circular, a through hole is opened in the middle of the body, the overall cross section of the through hole is similar to a circle, and the through hole consists of several sections of circles with different centers from the body Composed of arc segments, the through hole is matched with the corresponding planetary pin shaft, and there are several first grooves distributed along the circumferential direction on the side of the main body that is in contact with the corresponding planetary carrier end surface, and one end of the first groove faces the through hole , the other end of the first groove is facing the outer edge of the body, the first groove and the bosses on the corresponding planet carrier are matched and fitted together one by one, and the body is provided with a Several second grooves distributed along the circumferential direction, one end of the second groove faces the through hole and communicates with the through hole, the other end of the second groove faces the outer edge of the body, and the second groove is used for for storing lubricating oil. The invention has the advantages of simple structure, anti-rotation function and good wear resistance.

Description

technical field [0001] The invention relates to a planetary spacer. Background technique [0002] In the existing hybrid gearbox, the planetary gasket in the power splitting system of the planetary row assembly adopts a traditional common structure, such as an alloy steel sheet that has been treated with nitriding or high-frequency quenching, or is made of Resin spacers that are injection molded from resin materials. However, during the relative movement of the above-mentioned planetary gasket with the planetary carrier and the planetary wheel, since there is no anti-rotation measure and the wear resistance of the material needs to be improved, the planetary gasket is easy to wear and generates relatively large noise. When the amount of wear of the planetary gasket reaches a certain level, the planetary wheel is prone to serious partial load, which eventually leads to a greater risk of the power split system - the planetary row assembly. Contents of the invention [0003...
