Abstract

A standard gear 10 has a series of peripheral slots 11 cut across the face of each gear tooth. These slots are filled with a resilient material 12, such as urethane, foam, rubberized filler or the like, bonded in place and/or formed as inserts. The resilient filler 12 is slightly larger than the tooth profile, as shown. This provides a low-cost anti-backlash function when the gears are meshed and relatively quiet running operation.
