Abstract
Driving systems for belted machines have in the past utilized a common material interface to drive the belted machine. For example, rubber belted machines have generally used a rubber drive therewith. The present drive wheel is made of metal and includes a plurality of contacting elements attached to the outer surface of a drum. Each of the contacting elements have a contacting surface have a generally diamond configuration defining a leading point of contact, a trailing point of contact, a major length and a minor length. The plurality of contacting elements are arranged on the drum in a plurality of spaced apart rows which extend circumferentially along and axis and each of the major lengths coincide with the axis. Furthermore, the major length is greater in length than the minor length. The plurality of contacting elements extend from the outer surface a preestablished distance and the interface of the preestablished distance and the contacting surface form a sharp edge 67 or a point 68. Thus, this point 68 or sharp edges 67 of the diamond drive wheel aggressively separates the debris and enables a positive interface or contact between the drive wheel and an inner surface of a belt.
