ABSTRACT:
A multiple substantially identical countershaft (16, 16A), simple change gear transmission (10) having two-piece (20, 20A, 22, 22A) countershafts is provided. The use of two-piece countershafts allows the countershafts to be supported by three bearings (72, 74 and 76) while not requiring greater than normal manufacturing accuracy of the transmission housing (H). A driving connection between the front and rear countershaft portions is utilized which will allow a degree of axial misalignment between the front and rear portions and which when connected assures proper circumferential alignment of the countershaft gears. In the preferred embodiment, proper circumferential alignment of the front (20, 20A) and rear (22, 22A) countershaft portions is assured by providing a splined connection between the countershaft portions wherein the number of spline teeth (37, 66) is evenly divisible into the number of countershaft gear teeth carried by any gear on one of the countershaft portions (22, 22A) and wherein each spline tooth carried by the one countershaft portion has the same circumferential alignment with the countershaft gear teeth carried by said one portion as all of the other spline teeth carried by the one portion.
