ABSTRACT:
A gear mounting for use in a compound change gear transmission (10) having an intermediate wall portion (50), and a shaft support portion (66) axially spaced from the intermediate wall portion (50). Disposed axially between the intermediate wall portion and the shaft support portion is a gear member (48). The intermediate wall portion and shaft support portions define aligned shaft bores (92,96) with the shaft member (98) disposed therein, and including retention means (122) to retain the shaft member within the bores. The shaft member defines lubricant passage means (100) permitting flow of lubrication fluid through the shaft and into a set of bearings (64) which receive the forward end of an adjacent countershaft (60). The outer surface of the shaft member (98) defines an inner race for a set of bearings (120) disposed between the shaft and the gear member (48). The disclosed mounting arrangement substantially simplifies and strengthens the mounting of the gear member (48).
