摘要： Improved mainshaft gear retainer means for a twin countershaft transmission having floating mainshaft gears positioned close together in groups of two and clutchable to a mainshaft one at a time by positive clutches which each have splines mateable with splines defined by each gear. The improved mainshaft gear retainer means prevents axial movement of two closely positioned gears and includes a snap ring axially interconnecting the gears, a thrust ring interposed between the axially interconnected gears, and a snap ring carried by each axially interconnected gear.

摘要： An improved mainshaft gear retainer assembly (66, 68) for a multiple countershaft (18, 18A) transmission (10) having at least one pair of floating mainshaft gears (44-46, 48-50) positioned axially close together in groups of two and clutchable to a mainshaft (40) one at a time by positive clutches (54, 56, 58) is provided. The improved mainshaft gear retainer assembly prevents axial movement of the two closely positioned gears and reacts the axial forces on a clutched one of the mainshaft gears toward and away from the other mainshaft gear to the mainshaft by means of thrust surfaces (46D--82B,82C--78C, 78D--74B, 74C--70, 94B--82C or 82B--84) which are all rotating, or tending to rotate, at the same speed as the clutched mainshaft gear and the mainshaft. The gear retainer comprises relatively simple components and allows easy assembly and disassembly of the mainshaft gears and gear retainers from the mainshaft. Each of the closely spaced mainshaft gears and certain associated retainer components defines a subassembly (44, 76 and 90) and (46, 82 and 94) which is independently assembled to and removed from the mainhaft assembly (20). The improved retainer assembly components are all received in the circumferential space defined by the root diameter (42A) of the mainshaft splines (42) and the root diameter (44B and 46B) of the gear internal clutch teeth (44A and 46A).
