Abstract

The invention discloses an NW type planetary gear reduction device and a transmission system, belonging to the technical field of transmission. The NW type planetary gear reduction device includes: the secondary planetary gear is rotatably arranged between the first planetary gear bracket and the second planetary gear bracket, the secondary planetary gear is composed of a conical part and a cylindrical part; the locking part and the The conical part of the second-stage planetary gear is connected; the first-stage planetary gear is sleeved on the conical part of the second-stage planetary gear, and the first-stage planetary gear is arranged between the locking member and the cylindrical part of the second-stage planetary gear; the sun gear is rotatable The sun gear is arranged between the first planetary gear carrier and the second planetary gear carrier, and the sun gear meshes with the first-stage planetary gear. The NW type planetary gear reduction device and the transmission system of the present invention reduce the manufacturing difficulty, and the relative phase angle of the two planetary gears is adjusted according to the actual meshing situation during the assembly process, and the meshing force of the gears will not be affected by poor assembly precision control.

Description

technical field [0001] The invention relates to the field of transmission technology, in particular to an NW type planetary gear reduction device and a transmission system. Background technique [0002] Planetary gear transmission has the advantages of light weight, small size, high efficiency, power, and large speed range. It is widely used in various transmission systems. The planetary reduction mechanism with a speed ratio between 7 and 21 generally adopts an NW type planetary reduction mechanism or a two-stage The NGW type planetary reduction mechanism series scheme, in which the NW type planetary reduction mechanism has a relatively small volume and weight, has more advantages. few. [0003] NW-type planetary reduction mechanism is used less because of its planetary gear design, processing, manufacturing, and installation have certain restrictions: the planetary gear of NW-type planetary reduction mechanism generally adopts split planetary gears, but in the prior art, ...
