ABSTRACT:
A novel seal member for a known drive system of the type used in General Motors diesel locomotives and the like which is applicable between the outer seal member of the traction motor and an associated pinion and provides a lip seal to reduce escape of lubricant through migration up the armature shaft and a return duct for conducting lubricant from drain openings of an internal labyrinth seal back into the gear case while blocking any interfering lubricant flow generated by gear action from impinging upon the drain openings and being forced out of the gear case.
