Abstract

The invention discloses a two-stage plane movable tooth speed reducer coupled by a hollow movable tooth frame, and relates to the technical field of mechanical transmission. The two-stage plane movable tooth speed reducer coupled by the hollow movable tooth frame comprises an input shaft and an output shaft; a first-stage shock wave device and the input shaft are designed in a split mode; the output torque of the input shaft is transmitted through a rotating arm bearing; the first-stage output and the second-stage input are integrally designed into a first-stage hollow movable tooth frame; a second-stage shock wave device and the first-stage hollow movable tooth frame are designed in a split mode; the output torque of the first-stage hollow movable tooth frame is transmitted through the rotating arm bearing as well; first and second-stage central wheels are fixed; the output shaft serves as the output end of the whole speed reducer; the right end of the input shaft and the left end ofthe output shaft extend into a hole of the first-stage hollow movable tooth frame through matching with a bearing; a first-stage transmission input end is the input shaft, and the first-stage hollow movable tooth frame is the output end; the second-stage transmission input end is the first-stage hollow movable tooth frame; and the second-stage transmission output end is the output shaft. The two-stage plane movable tooth speed reducer is stable in transmission, high in input-output end rigidity, small in self-excitation force and compact in axial structure.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a double-stage planar movable gear reducer coupled with a hollow movable gear frame. Background technique [0002] With the continuous development of research on movable tooth transmission, many transmission structure forms have appeared, which can be roughly divided into two categories: swing movable tooth transmission and mobile movable tooth transmission according to the structural characteristics. Planar movable tooth transmission is a very representative transmission type in mobile movable tooth transmission. It has the advantages of good dynamic balance, wide range of transmission ratio, high transmission precision and high efficiency, and has a compact axial structure compared with other transmission types. , The structure can be subdivided into various forms, and there is no need for a constant speed output mechanism. It has a certain application potentia...
