ABSTRACT:
An oil passage connection between a shaft and a clutch drum is sealed by intentionally providing an imbalance in the forces acting on splines mounting the clutch drum to the shaft. The sides of at least some of the splines are angled, so that at least some part of any torque applied between the clutch drum and shaft is resolved into radial components. By providing a differing number of splines, or an asymmetrical positioning of the splines, the net force can be designed to force the sides of the shaft and the clutch drum adjacent to the oil passage tightly together. This is most easily accomplished by simply omitting one or more splines from the clutch drum on either side of the oil passage. With such a structure, the same splines on the shaft can be used to mount gears and the like, which normally require symmetrical distribution of forces.
