Problems solved by technology

Among the three major reducers used in robots, the harmonic reducer has the highest precision, but has poor accuracy retention and short life, and is mainly used for small torques such as robot joints; RV reducers have long life, complex structure, and high cost. It is mainly used in the occasion of large speed ratio and high torque; precision planetary reducer has a small single-stage reduction ratio, and requires multi-stage combination to achieve a large speed ratio, so it is large in size and low in accuracy

Abstract

The invention discloses an improved planetary reducer, which comprises a center wheel, a stationary wheel circumferentially arranged along one end of the center wheel, at least one planetary gear mechanism arranged between the stationary wheel and the center wheel, and an output wheel circumferentially arranged at the other end of the center wheel, wherein the planetary gear mechanism comprises aplanetary carrier rotatably arranged on the stationary wheel, a planetary shaft arranged on the planetary carrier, and a planetary gear rotatably arranged on the planetary shaft, and the stationary wheel, the output wheel and the center wheel are coaxially arranged; the axis of the planetary wheel is parallel to the axis of the center wheel, and the planetary gear is meshed with the center wheel,the stationary wheel, and the output wheel; the tooth number of the stationary wheel is different from that of the output wheel. The improved planetary reducer provided by the invention has the advantages of simple structure, low cost and high precision.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to an improved planetary reducer. Background technique [0002] The precision large speed ratio reducer is a mechanical power transmission mechanism, the purpose is to reduce the speed and increase the torque. In recent years, with the development of industrial robots, one of the core components of robots, the slow development of precision high-speed ratio reducers has become a long-standing problem in the development of robots. Among the three major reducers used in robots, the harmonic reducer has the highest precision, but has poor accuracy retention and short life, and is mainly used for small torques such as robot joints; RV reducers have long life, complex structure, and high cost. It is mainly used in the occasion of large speed ratio and high torque; the single-stage reduction ratio of the precision planetary reducer is small, and multi-stage combination is required to ach...
