SUBSTANCE: rotary movement transfer mechanism includes a housing, in which an eccentric drive shaft, a driven shaft and intermediate link located on the drive shaft are installed with possibility of being rotated. The mechanism housing is provided with a central gear with satellites and free-wheel mechanisms with inlet and outlet links. Central gear is rigidly attached to the intermediate link. The inlet link of each free-wheel mechanism is connected to the corresponding satellite, and the outlet link of each free-wheel mechanism is connected to a hinge installed on the mechanism housing. Rotary movement is transferred to the outlet shaft through kinematic connection to the intermediate link.

EFFECT: improving reliability and durability of rotary movement transfer mechanism and increasing the mechanism efficiency.

SUBSTANCE: invention is designed for stepless change of gear ratio in transmissions at high transmitted power. Proposed variable-speed drive contains input and output shafts, vibratory mechanism set into operation by input shaft with pair of vibratory shafts operating at relative 90° phase shift, flywheels, three-shaft gear differential mechanically coupled with output shaft by carrier and pair of vibration equalizers. Driving shafts of vibration equalizers are vibratory shafts, and driven shafts are shaft of differential gears. Variable-speed drive is furnished with flywheel rigidly connected with shafts of differential gears with inertia moment J applied to said shafts. Inertia moment J is related to moment on carrier Mc according to expression Mc<4Jω2(λ/π)u, where ω is speed on input shaft, λ is swing of vibrations of vibratory shaft and u is gear ratio between vibratory shaft and shaft of differential gear.

EFFECT: improved operating characteristics, simplified design and reduced cost of variable-speed drive.
