Patent number: ZL200620045371.2 The patentee: Shanghai Meishan Iron & Steel Co., Ltd. Inventor: Teng Hongyin Feng Chunrong Li Bo The utility model relates to the chain drive on the fixture of the large sprocket, in particular, to prevent the large sprocket in the transfer Torque slip torque sprocket assembly during torque. Mainly to solve friction friction plateau friction factor reduction for a long time technical problems. The technical scheme of the utility model is that: a torque anti-skid sprocket device comprises a sleeve, a friction ring, a large sprocket, an adjusting nut, a large sprocket and a friction ring sequentially sleeved on the sleeve, The utility model is characterized in that a plurality of through holes arranged uniformly in the circumferential direction are arranged on the end face of a large sprocket,
