Abstract
A gear spindle includes a shaft having a first gear cavity at a first end, an oil delivery path for delivering oil to the first gear cavity and an oil return path for carrying oil away from the first gear cavity. A first seal assembly is associated with the first end of the shaft for limiting leakage of oil from the first gear cavity, the first seal assembly including a sealing interface having one side in fluid communication with the first gear cavity and an opposite side in fluid communication with a fluid delivery path. The fluid delivery path may be connected to a source of pressurized air for reducing pressure differential across the sealing interface.
