TRANSMISSION GEAR RETAINER

摘要

A gear retainer (200) is provided that features a thrust washer (54) that is secured in a transverse groove (40) in a transmission mainshaft (3) for rotation therewith and extends outwardly therefrom into a groove defined between a radially outwardly extending second surface (50) and a retainer ring (58) disposed in a slot (47) in an axially extending first surface (46) defining a recess (42) in a floating mainshaft gear (20) encircling mainshaft (3). Gear retainer (200) is operative to limit axial movement of gear (20) and to transmit axial thrust to mainshaft (3) that may have been imparted thereto by a clutching mechanism (24) during the process of clutching gear (20) to mainshaft (3). In another embodiment a gear retainer (300) is provided that includes a spacer (62) between ring (58) and thrust washer (54) that is secured for rotation with gear (20) and is operative to increase contact surface area between ring (58) and thrust washer (54).
