Abstract

The invention relates to mechanical engineering and can be used in mechanisms for communicating rotational motion with variable speed. The aim of the invention is to expand the kinematic capabilities of the transmission by increasing the range of gear ratios. For this, by turning the roller 7, the deformer roller 5 is installed in the axial direction of the flexible wheel 1 and one of the main rigid wheels 3. At the same time, the pawl 9 enters one of the notches of the cam 8 and holds the deformer in a predetermined position. Under the action of the deformer, the flexible wheel 1 engages with a given rigid wheel 3 and one of the gears is engaged. The rotation of the input shaft 10 is transmitted through the coupled main rigid wheels 3 and additional rigid wheels 4, and then through the flexible wheel 1 connected to one of them to the output shaft 2. The number of possible gears of the box is equal to the number of hard wheels 3. 4 Il.
