METHOD AND APPARATUS FOR LOCALIZED GEAR TOOTH ROOT FILLET SHOT PEENING

摘要

A method of manufacturing a gear having root fillets between adjacent teeth that are shot peered to improve compressive strength. A robot moves a shot peening nozzle between adjacent teeth. A servomotor drive indexes the gear in increments corresponding to one or more teeth. The nozzle has a tapered tip that is moved between adjacent tooth faces with clearance relative to the tooth faces.
