Problems solved by technology

However, in many applications of planetary gear carriers, although the rotational speed of the planetary gear carrier is low, due to frequent start-stop or braking, the inertial acceleration caused by such frequent start-stop or brake is relatively large, so the planetary gear carrier The existence of the unbalanced weight of the dynamic balance on the gear frame has a great influence on the stability of the operation, and will increase the impact of the transmission gear and reduce the life of the gear

Abstract

The invention relates to the technical field of planetary gear transmission, in particular to a planetary gear carrier. The planetary gear carrier comprises a front planetary carrier body and a rear planetary carrier body. A connecting column connected with the rear planetary carrier body is arranged on the front planetary carrier body. A corresponding groove connected with the connecting column is formed in the rear planetary carrier body. Brazing holes are formed in the surface of the groove. The front planetary carrier body and the rear planetary carrier body are integrally connected through sintering and brazing. A transmission spline is arranged on the front planetary carrier body and is an outer spline. Island-shaped protrusion reinforcing structures are further arranged at the groove of the rear planetary carrier body and located at the two ends, in the circumferential direction, of the rear planetary carrier body. The planetary gear carrier has the advantages of being high in transmission strength, good in transmission stability, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of planetary gear transmission, in particular to a planetary gear carrier. Background technique [0002] The planetary gear carrier is the core part of the planetary gear transmission mechanism. The typical planetary gear carrier in the prior art is generally a planetary gear carrier with internal splines at one end, as Figure 5 shown. The planetary gear carrier with this inner spline structure is limited by the weight and wall thickness of the planetary gear carrier on the inner spline part, and its meshing length with the transmission shaft is short, so its transmission strength is low and the transmission stability is poor. . [0003] Usually, the traditional planetary gear carrier adopts the manufacturing method of integral casting followed by machining and forming. Due to the complex structure and shape of the planetary gear carrier itself, the processing cost is very high. For this reason, there is...
