Planetary balance wheel reduction gear

Abstract

The invention relates to a speed reduction device, and provides a planetary balance wheel reduction gear. The planetary balance wheel reduction gear has the characteristics of large carrying capacity,stable transmission and reliable use. According to the technical scheme, the planetary balance wheel reduction gear comprises a shell, an input shaft, an output shaft, a first-stage transmission mechanism and a second-stage transmission mechanism, wherein the input shaft and the output shaft are rotatably and coaxially disposed at two ends of the shell, and the first-stage transmission mechanismand the second-stage transmission mechanism are arranged in the shell and used for sequentially transmitting power between the input shaft and the output shaft. The planetary balance wheel reduction gear is characterized in that the first-stage transmission mechanism comprises a supporting frame fixed coaxially to the output shaft, a plurality of transmission shafts rotatably positioned in the supporting frame and uniformly arranged on the periphery of the input shaft, a driving gear fixed to the input shaft and a driven gear fixed to the transmission shaft and meshing with the driving gear; and the secondary transmission mechanism includes a plurality of needle rollers uniformly distributed on the inner wall of the shell in the circumferential direction, eccentric bearings fixed to the transmission shafts, a plurality of balance wheels mounted on the eccentric bearings and meshing with the needle rollers.

Description

technical field [0001] The invention relates to a reduction device, in particular to a planetary balance reducer. Background technique [0002] The balance gear reducer is a kind of transmission equipment widely used in all walks of life. Its working principle is that the input shaft first drives the balance wheel through the eccentric bearing, and then obtains a lower output speed through the meshing of the balance wheel and the pin gear. However, with the continuous development of industrial capabilities and the continuous improvement of the technical level, the existing balance wheel reducer has developed to a higher level, and it is difficult to make a breakthrough in the internal structure and working principle, and it is difficult to continue to improve the overall performance. The speed ratio has been unable to meet the user's further use requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings in the abo...
