ABSTRACT:
A gear device such as a change gear transmission of the countershaft (21) type in which, mounted for rotation about the countershaft is a larger gear (17) and a smaller gear (29). The transmission housing (11) defines a first lubricant reservoir (R1), having a nominal fill level (L1), which is able to lubricate the smaller gear as it rotates. A partition member (51) is disposed around the larger gear and defines a second lubricant reservoir (R2) through which the larger gear passes as it rotates. The partition member defines fluid passages (71,73) providing restricted communication from the first reservoir to the second reservoir. The fluid passages (71,73) are sized such that as the larger gear rotates, carrying lubricant out of the second reservoir (R2), there is maintained in the second reservoir a second fill level (L2), below the first fill level (L1) such that at least a portion of the teeth of the larger gear (17) pass just below the second fill level as the larger gear rotates. The result is substantially reduced churning losses, without decreasing the ability to lubricate the smaller gears.
