Single-wave speed reducer with round-head roller pins

Abstract

The invention discloses a single-wave speed reducer with round-head roller pins. The single-wave speed reducer with the round-head roller pins comprises an input shaft, an installation shell, a speed reduction assembly, an output shell and a roller mechanism, wherein the input shaft is rotationally arranged in the installation shell; the output shell is rotationally arranged on the installation shell; the speed reduction assembly is arranged in the installation shell, one end of the speed reduction assembly is connected with the input shaft, and the other end of the speed reduction assembly is connected with the output shell; the speed reduction assembly comprises a driving disc, an installation groove, speed reduction roller pins and an epicycloid groove, the epicycloid groove is formed in the driving disc, the installation groove is formed in the output shell, and the installation groove and the epicycloid groove are oppositely formed; one end of each speed reduction roller pin is arranged in the installation groove, and the other end of each speed reduction roller pin is arranged in the epicycloid groove; and the roller mechanism comprises a first transmission groove, round-head rollers and a second transmission groove. According to the single-wave speed reducer with the round-head roller pins, the torque can be increased, and jumping is avoided.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a round-head needle roller single-wave reducer. Background technique [0002] In the production process of mechanical equipment, it is necessary to adjust the rotational speed ratio of the two stages through the reducer, so as to reduce the high-speed rotation of the upper-stage equipment, so as to obtain a larger torque. The existing ball head single-wave reducer generally adopts gear meshing mode for transmission, and the deceleration effect is realized through the tooth difference between the gears. With the improvement of automation, in the same production line, it is often necessary to use multiple ball-head single-wave reducers, and the ball-head single-wave reducer with gear meshing, in the transmission process, the gap between the gear and the gear The sliding friction between them will cause great mechanical loss. When the ball-head needle roller single-wave reducer in a certain...

With the improvement of automation, in the same production line, it is often necessary to use multiple ball-head single-wave reducers, and the ball-head single-wave reducer with gear meshing, in the transmission process, the gap between the gear and the gear The sliding friction between them will cause great mechanical loss. When the ball head roller single-wave reducer in a certain link fails, it will easily affect the production efficiency of the entire production line.
