FIELD: machine engineering.
SUBSTANCE: chain drive (1) contains the drive shaft (3). Drive power or drive torque is transmitted to the link chain (2) by means of the elements (4) that perform the functions of the teeth of the sprocket. Elements (4) are inserted directly into the drive shaft (3) into the sockets (6). The sockets (6) have a depth (X) and the elements (4) have a free tooth height (Y) that is measured between the outer circumference (U) of the drive shaft (3) and the engaging line (WL) of the chain link (2). The ratio of the depth (X) to the height (Y) of the free tooth is between 1:1 and 1:2.5 and preferably not more than 1:2.
EFFECT: required stability of the elements that perform the function of the teeth of the sprocket, with their coupling areas in the sockets, a reliable transfer of force from the drive shaft to the link chain.
