Starting mechanism // 2539715

FIELD: machine building.

SUBSTANCE: invention relates to the machine building and can be used in designs of mechanisms, the reduction ratio of which is to be varied in a wide range. The starting mechanism consists of differential transmission and slipping power coupling (2). The differential transmission has one input and two outputs. One output is coupled with the driven shaft and rotates in the same direction with the drive. The second output is coupled with the input of the differential and the drive shaft through the slipping power coupling (2), which partially blocks the differential, that results in decrease of the total ratio from the maximum value, when the motion is transmitted only through elements of the differential transmission, down to a minimum value after acceleration. With increase of loading on the driven shaft, when it is braked, the slipping in the power coupling is increased, the differential elements increase the relative motion with reference to each other, and the rotation of the whole mechanism around the shaft is decelerated, the reduction ratio of the mechanism and torque on the driven shaft are increased, the speed of the driven shaft is decreased.

EFFECT: invention is aimed at simplification of process of acceleration, simplification of the mechanism and energy saving.
