Abstract
A sprocket for an inside flank engagement inverted tooth chain includes tooth spaces each defined at least partially by the engaging flank of one tooth, the disengaging flank of another tooth, and a root surface that is located between the engaging flank and the disengaging flank of the tooth space. The engaging flank of each tooth space is defined as a mirror image of the disengaging flank of each tooth space relative to a tooth space centerline such that each tooth space is symmetrically defined about its tooth space centerline. The sprocket teeth include Type A Standard Teeth, Type B Standard Teeth, Type A Relieved Teeth, and Type B Relieved Teeth. The engaging flank of each Type A Relieved Tooth and both the engaging and disengaging flanks of each Type B Relieved Tooth are relieved or negatively offset. The root surface preceding a Type A Relieved Tooth or a Type B Relieved Tooth is raised so as to be located radially outward as compared the root surface preceding a Type A Standard Tooth or a Type B Standard Tooth.
