Abstract
A drive sprocket assembly for driving an endless chain assembly for propelling a machine has a hub portion and flexible cantilever teeth in which each tooth is separately deflectable upon impact by a bushing of the endless chain assembly. The flexibility of each tooth will absorb a portion of the kinetic energy of the impact to reduce noise in the structure. The drive sprocket assembly includes a plurality of segments each having the cantilever teeth. Each segment has a first end portion and a second end portion having an end relief which prevents wear between the segment and the hub as the end portion is deflected by the impact.
