Exciter

The exciter housing as claimed in claim 0, wherein the bearing cover abutment surface includes a plurality of channels, wherein the channels are circumferentially spaced around the through holes.

The exciter housing as claimed in claim 0, wherein each channel extends through the front and back walls such that a channel in one bearing cover abutment surface aligns with a respective channel in the opposing bearing cover abutment surface to provide fluid communication between one bearing cover abutment surface, the passageway, and the opposing bearing cover abutment surface.

The exciter housing as claimed in claim 0, wherein each lug is spaced inwardly from an end of the body.

An end cover for a unitary exciter housing body having a longitudinal passageway defined by a top, bottom, opposing sidewalls, and opposing ends, where each opposing end is smaller than the top, bottom or opposing sidewalls, and where at least one of the opposing ends defines an opening for receiving a gear, the end cover comprising:

• a mounting surface perimeter for coupling to the exciter housing body;
• an arcuate base upstanding from the mounting surface perimeter and having a front wall, a back wall spaced apart from the front wall, and a thermal cooling feature;
• wherein the end cover is configured to cover the opening of the exciter housing body.

The end cover as claimed in claim 0, wherein the thermal cooling feature comprises a plurality of fins upstanding from the arcuate base.

The end cover as claimed in claim 0, wherein the arcuate base defines a cavity on an inner surface thereof.

The end cover as claimed in claim 0, wherein the mounting surface perimeter defines a lubrication aperture configured to receive a removable plug for draining or adding lubricating fluid to the cavity.
