Abstract
An improved sprocket configuration for use in a track-type vehicle drive. The tooth configuration and tooth pocket configuration accommodate packing of the pocket and permit limited displacement of the chain without excessive wear of the chain bushings. The pocket configuration is relatively deep so as to permit a preselected amount of packing in the pocket root to minimize the chain bushing displacement. The improved tooth configuration provides a rounded topping surface avoiding bushing wear as may occur with sharp corner tooth configurations of the prior art.
