Abstract
A sprocket assembly includes a carrier and a plurality of sprockets. The carrier has a central axis. Each of the sprockets has a different number of teeth and is formed with a central through hole. The carrier extends into the central through hole of each of the sprockets such that the sprockets are disposed on an outer periphery of the carrier and are disposed along the central axis. At least one of the sprockets is coupled to the carrier by a weld that is formed via a solid-state welding technique.
