A sprocket is provided, the sprocket having a body with a central opening for engaging a shaft and rotating about an axis. The sprocket has a plurality of teeth disposed around the periphery of the body. The teeth are angularly spaced about the axis such that each tooth is spaced from the adjacent teeth by a first opening. Each tooth has a belt-contacting surface which is convex in shape such that the outer-most periphery of the sprocket is generally circular. The belt-contacting surfaces of the teeth guide the belt around the periphery of the sprocket in order to minimize the ability of the belt to buckle. |
