ABSTRACT:
A check valve provides improved lubrication of a bearing contained within a gear. The check valve is positioned within a bore in the gear, the bore extending radially inwardly from the gear teeth to the bearing. In a preferred embodiment, a ball check valve is contained in a transmission drive gear, the gear containing a pocket bearing. The ball of the check valve is held against the check valve seat by centrifugal force created by the rotation of the drive gear. As the drive gear teeth mesh with those of a countershaft gear, pulses of transmission oil are forced into the bore, intermittently unseating the ball against centrifugal force to provide a continuous supply of oil to the pocket bearing.
