ABSTRACT:
A venting system is disclosed in connection with a high speed electric motor having oil bath lubricated ball bearings. The bracket and cap which enclose the bearing define mating passageways which, in combination upon assembly, lead from inside the inboard bearing seal to the outside atmosphere. The venting passageway maintains a chamber next to the bearing seal at substantially outside atmospheric pressure, so that no lubricant will be sucked out of the bearing structure. However, because the passageway is formed automatically upon assembly of the cap and bracket, no extra steps or awkward assembly of parts is required.
