摘要： A high torque sprocket includes a body defining an outer periphery and a hub section defining an inner surface for engaging a bushing. A continuous toothed structure is disposed on the outer periphery of the body, and a textile reinforcement embedded in the body adjacent the inner surface of the hub section. The body is formed of a castable polymer material. In some cases, one or two optional flanges are disposed on side(s) of the body immediately adjacent the continuous toothed structure, in some aspects, a textile reinforcement may be embedded in a surface of the flange(s) immediately adjacent the continuous toothed structure. In some aspects, ultra-high molecular weight polyethylene (UHMWPE) is incorporated into the castable polymer material mixture in an amount suitable to provide increased durability to the sprocket.
