Abstract

The invention discloses a two-stage closed type cylindrical sine end surface movable teeth reducer. A high-speed stage comprises an input shaft, a center wheel, three planetary gears distributed in aradial direction, a sun gear and three planetary wheel shafts to form a 2K-H type differential gear train. A low-speed stage comprises a shock wave device, a fixed movable tooth frame, movable teeth,a movable gear and an output shaft. The sun gear and the movable gear are fixedly connected into one component, and rotation of the movable gear is fed back to the sun gear as input movement of a high-speed stage differential gear train, so that two-stage closed type planetary transmission is formed. The left ends of the planetary wheel shafts are fixedly connected with the planetary gears respectively, the right ends of the planetary wheel shafts are connected with corresponding pin holes on the shock wave device to form a rotating pair, the autorotation movement of the shock wave device is implemented through revolving movement of the planetary gears, and then an axial shock wave is generated. For the two-stage closed type cylindrical sine end surface movable teeth reducer, a transmission chain is shortened to the maximum, the transmission efficiency and the reliability are improved, the axial structure is compact, the large reduction ratio and multi-tooth engagement are realized, the rigidity is large, the bearing capacity is strong, and transmission is stable; and compared with a common movable gear, the two-stage closed type cylindrical sine end surface movable teeth reducer has the characteristic of the axial shock wave.

Description

technical field [0001] The invention relates to the field of planetary transmission, in particular to the field of transmission with few tooth differences, and in particular to a two-stage enclosed cylindrical sinusoidal end surface movable tooth reducer. Background technique [0002] With the development of production and the progress of science and technology, higher and higher requirements are put forward for the mechanical transmission system. However, the conventional planetary transmission has been difficult to meet the requirements of the system. Therefore, it has become an increasingly important development trend in the field of mechanical transmission to develop an ideal transmission device suitable for the development requirements of new technologies and new equipment. The planetary gear transmission with movable teeth and few tooth differences is referred to as movable tooth transmission. It is a mechanical transmission used to transmit the rotary motion between t...
