Embodiment Construction

[0008] The new planetary gear reducer has a large planetary gear (2), the large planetary gear (2) is aligned with the keyway of the large planetary gear (9), and the small planetary gear (6) is aligned with the keyway of the small planetary gear (8). At the shift position of the planetary gear carrier (1), place the fixed key (7) in the fixed key keyway (10) of the gear shaft (3), and the gear shaft (3) passes through the holes on one side of the planetary gear carrier in sequence The center hole of the large planetary gear (2) and the small planetary gear (6), and one end of the gear shaft (3) reaches the hole on the other side of the planetary gear carrier (1), and the outer rings of the two bearings (4) are installed In the hole on one side of the planetary gear carrier (1), the inner rings of the two bearings (4) are connected with one end of the gear shaft (3).

Abstract

The invention discloses a novel planetary gear reducer. A big planetary gear is aligned to a big planetary gear key groove. A small planetary gear is aligned to a small planetary gear key groove and is placed at an opening of a planetary gear frame. A fixed key is arranged in a fixed-key key groove of a gear shaft. The gear shaft passes through central holes of the small and big planetary gears in sequence from a hole at one side of the planetary gear frame, and one end of the gear shaft gets into a hole at the other side of the planetary gear frame. Outer rings of two bearings are arranged in the hole at one side of the planetary gear frame. Inner rings of two bearings are connected with one end of the gear shaft.

Description

technical field [0001] The invention relates to a planetary gear reducer, in particular to a novel planetary gear reducer, which belongs to the technical field of planetary gear reducers. Background technique [0002] At present, in the planetary gear reducer, the two planetary gears installed on the planetary gear carrier are structurally connected double gears. The structure of this integral double gear has poor manufacturing process. The defect that the processing accuracy is difficult to guarantee. Contents of the invention [0003] The purpose of the present invention is to provide a new type of planetary gear reducer to overcome the above-mentioned defects in the existing planetary gear reducer. [0004] The technical solution adopted by the present invention to achieve the above purpose is: a new type of planetary gear reducer, which is aligned with the keyway of the large planetary gear and the large planetary gear, aligned with the keyway of the small planetary g...
