Problems solved by technology

[0002] Planetary gear reducer is a new type of mechanical variable speed transmission device, there are 2K-H, 3K, K-H-V and other types. Compared with other types of reducers, planetary gear reducer is widely used in petroleum, chemical industry, machinery, construction, mining and other industries, and in the field of electric formula car transmission, although the planetary gear reducer has an irreplaceable position, the existing planetary gear reducer cannot comprehensively meet the small space required by the electric formula car. Special requirements such as high speed and high power, and an output shaft adapted to the hub of a racing car

Abstract

The invention discloses a planetary carrier, comprising: a planetary carrier body and a spherical cage shell coaxially fixedly connected with the output end of the planetary carrier body, the spherical cage body and the planetary carrier body are integrally formed, the present invention Also provided is a compact planetary gear reducer comprising: an input shaft, a sun gear, a planetary carrier as described above, a planetary carrier cover, a planetary shaft, a planetary gear, an inner ring gear, and the input shaft is used to connect power input equipment , the input shaft transmits the power to the sun gear, and the sun gear transmits the power to the planetary gear that meshes with it. The planetary gear drives the planetary carrier body to rotate, thereby transmitting the power to the cage shell. The body is integrated together, which reduces the number of parts, shortens the transmission route, and realizes the miniaturization design of the planetary gear reducer.

Description

technical field [0001] The invention relates to the technical field of mechanical variable speed transmission, in particular to a compact planetary gear reducer and its planet carrier. Background technique [0002] Planetary gear reducer is a new type of mechanical variable speed transmission device, there are 2K-H, 3K, K-H-V and other types. Compared with other types of reducers, planetary gear reducer is widely used in petroleum, chemical industry, machinery, construction, mining and other industries, and in the field of electric formula car transmission, although the planetary gear reducer has an irreplaceable position, the existing planetary gear reducer cannot comprehensively meet the small space required by the electric formula car. Special requirements such as high speed and high power, and an output shaft adapted to the hub of a racing car. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficien...
