SU1640487A1 - Sine ball reduction gear - Google Patents

Abstract

The invention relates to mechanical engineering. The purpose of the invention is to increase the load capacity. In a sinus ball reducer, as the drive shaft 11 rotates with the inner bushings 3, the balls 8 interact with the sinusoidal racetracks of the inner 3 and outer 2 sleeves, the carrier 4 and the associated driven shaft 5 rotate. drove 4 in the area between the two extreme rows of slots 9 drove from the side of the driven shaft 5 allows to increase the load capacity of the carrier 4 10 sludge.

Claims (1)

Claim A sinus ball reducer comprising a housing, drive and driven shafts, planetary gears, each of which includes two coaxially mounted bushings with sinusoidal treadmills, the inner of which is connected to the drive shaft, and the outer to the housing, connected to the driven shaft, made in the form of a pipe with longitudinal slots having rounded ends at the ends and balls placed in the slots for interacting with sinusoidal treadmills, characterized in that, in order to increase the load capacity by selecting the shape of the carrier, the carrier portion contained between the planes passing through the centers of curvature of adjacent rounded portions of the slots corresponding to the two extreme rows from the output shaft, is thickened and the corresponding sleeve of the same rows have groove under the thickening.
