A reduction gear includes a drive and a driven shafts installed in reborings of the body coaxially with respect to each other, at the free end of the drive shaft a support bearing is installed, on the drive shaft with shift in axial direction a screw and a square are fixed in sequence. The outer surface of the screw is connected to the bushing that surrounds sit, its outer surface is rigidly connected to the pole that is rigidly connected to the flywheel, and the outer surface of the square is surrounded with an additional bushing to which a centering disc is fixed, this interacts with the inner surface of the body through the bearings. In the flywheel, eccentrically with respect to the last one, a toothed wheel with inner teeth is installed, this is in engagement with the pinion that is rigidly fixed to the reboring of the body as a ring connected to the flywheel by means of a holder one end of which is connected by means of bearings to the outer surface of the ring of the driven shaft, and the other end in free way goes through the flywheel. In the ring driven shaft is placed, this is made as a crank one, its output end is connected to it through the bearings, and the opposite end, as a crank, is rigidly fixed to the additional bushing.
