Abstract

The invention discloses a planet speed reducer which comprises an input flange and an annular gear connected with the input flange through screws. An input shaft is arranged in the input flange through an input shaft bearing, and an output shaft is arranged in the annular gear through an annular gear bearing. The input shaft is connected with a first level sun wheel which is matched with a first level planet wheel. The first level planet wheel is connected with a first level planet frame, and the first level planet frame is connected with a second level sun wheel which is matched with a second level planet wheel. The second level planet wheel is connected with the second level planet frame. The second level planet frame is connected with the output shaft, and the first level planet wheel and the second level planet wheel are respectively arranged on a needle roller through a planet wheel bearing in a rotating mode. The first level planet frame and the second level planet frame are respectively provided with folding edges. The planet speed reducer has the advantages that the plant frame is of a double-edge structure, the planet shaft is even in force, and transmission is stable.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a planetary speed reducer. Background technique [0002] In addition to the planetary gears in the planetary reducer can rotate around their own axis of rotation like fixed shaft gears, their axis of rotation also rotates around the axis of other gears (sun gear) with the planet carrier, and the rotation around its own axis It becomes rotation, and the rotation around the axis of other gears is called revolution, just like the planets in the solar system, hence the name. The planet carrier in the existing planetary reducer has a unilateral structure, which easily causes uneven force on the planet shaft and affects the transmission effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a planetary reducer with more stable transmission. [0004] In order to solve the above technical problems, the technical solution adopted in the p...
