FIELD: mechanical engineering.
SUBSTANCE: gearing comprises housing, input shaft (1) mounted inside the housing and provided with the wave generator, output shaft, and flexible and solid wheels. The flexible wheel is made of cylinder (11) with radial grooves arranged over its two diametrically opposite generatrices. The grooves receive rolling bodies that define gearing rims. The wave generator is made of assembly of eccentric bushings (2) and (3) set in rolling bearings (4). The solid wheel is made of two spring-loaded to each other flat sectors with the gearing rims at the faces and cooperates with the gearing rims of the flexible wheel.
EFFECT: increased service life.
