FIELD: machine building.
SUBSTANCE: chain drive includes a drive with the driving (10) and driven sprocket and an endless chain, performed with alternating links of two steps of different size. On the sprocket an additional contour of engagement with a bearing hinge is made. Teeth (11, 12) of the sprocket, contacting with a bearing hinge, are made with different side profiles, corresponding to the geometry of mating hinge of the load-bearing chain link. The bearing hinge is additionally equipped with roller (13), which provides running-in of the side profile of the teeth sprocket in contact with the bearing link. The axis of the bearing hinge are made compatible with a pitch circle in relation to the leading sprocket.
