Abstract

The invention discloses a planetary reducer which comprises a sun gear connected with an output shaft of a gearbox through a sun gear shaft. The planetary gear carrier is coaxial with the sun gear, the sun gear is contained in the planetary gear carrier, and one end of a sun gear shaft extends out of the planetary gear carrier; the planetary gear assembly is meshed with the sun gear and rotationally connected to the planetary gear carrier; at a high gear, power is output through an internal spline on the sun gear; and at the low gear, the power passes through the planetary gear assembly and then is output through an internal spline on the planetary gear carrier. The method has the advantages of good manufacturability, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission components, and in particular relates to a planetary reducer. Background technique [0002] At present, the planetary gear carrier of the existing planetary reduction mechanism adopts forging or casting process design structure, the forging blank is irregular, the margin is large, the process is long, the manufacturing cost is high, the casting blank has many defects such as trachoma, and the rejection rate is high; at the same time, the planetary reduction mechanism is At the power input end of the transfer case, the input speed is high, the load becomes larger after deceleration, and the planetary gear gasket is prone to ablation and other problems. Contents of the invention [0003] In view of the problems of high manufacturing cost of the planetary gear frame of the existing planetary reduction mechanism, ablation of the planetary gear gasket, and low service life, the purpos...
