Abstract
A starting motor pinion gear assembly comprises a powdered metal pinion disposed and retained within a castellated drawn metal cup having axially extending tangs which are staked between adjacent pinion teeth. The tangs are staked against a plurality of fillets or projections which extend radially outwardly from the bottom land of the pinion and form a discontinuous web between the pinion teeth adjacent one end of the pinion. Also disposed within the drawn cup is a splined drive collar which engages a mating spline on the output shaft of the starting motor and a torque limiting friction clutch. The pinion gear assembly mounts on the output shaft of the starting motor and momentarily engages a ring gear on the flywheel of an internal combustion engine to effect cranking of the engine.
