Problems solved by technology

[0002] Gears are generally used for acceleration or deceleration. Existing gears generally include sun gears, brackets, ring gears and planetary gears. However, there will be backlash at the meshing position of planetary gears, sun gears and ring gears. Due to the existence of this backlash, There will be a problem that the output member on the combined epicyclic gear mechanism cannot be correctly controlled, or the rotational position of the epicyclic gear mechanism device, resulting in the inability of the output member to be positioned accurately

Abstract

The invention discloses a transmission gear which comprises a sun gear, a ring gear and a frame body, wherein the sun gear is arranged on an input shaft in a sleeving manner; the ring gear is arranged on an output shaft in a sleeving manner; a first planetary gear, a second planetary gear, a third planetary gear and a fourth planetary gear are arranged between the sun gear and the ring gear; and the first planetary gear, the second planetary gear, the third planetary gear and the fourth planetary gear are meshed with the sun gear and the ring gear. According to the transmission gear, the problem that an output part cannot be accurately located is effectively solved, and the transmission gear has the benefits of being easy to transform, long in service life, reduced in cost, and the like.

Description

technical field [0001] The invention relates to a gear, in particular to a gear capable of precise positioning. Background technique [0002] Gears are generally used for acceleration or deceleration. Existing gears generally include sun gears, brackets, ring gears and planetary gears. However, there will be backlash at the meshing position of planetary gears, sun gears and ring gears. Due to the existence of this backlash, There will be a problem that the output member combined with the epicyclic gear mechanism cannot be correctly controlled, or the rotation position of the device provided with the epicyclic gear mechanism, so that the output member cannot be positioned accurately. [0003] Therefore, those skilled in the art are devoting themselves to developing a gear structure capable of precise positioning. Contents of the invention [0004] In view of the above-mentioned defects of the prior art, those skilled in the art are devoting themselves to developing a gear ...
