Abstract
An apparatus includes a non-metal high torque sprocket and non-metal bushing. The non-metal 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 disposed on the outer periphery of the body, and a textile reinforcement embedded in the body adjacent the inner surface of the hub section, wherein the body is formed of a castable polymer material. The hub section inner surface is a tapered shape, and is adapted to engage a conventional QD bushing or a taper-lock bushing. The non-metal bushing is engageable by the hub section inner surface of the high torque sprocket. The non-metal bushing may be formed of a castable polymer material, which may optionally include ultra-high molecular weight powder. According to some embodiments, the non-metal bushing is a QD bushing.
