An oil level sensor comprises a body having a probe extending away from a nominal body portion. The probe receives a resistance thermal device and extends for a height away from the nominal surface. The probe has an outer dimension. The ratio of the outer dimension to the height is between 0.1 and 0.2. The RTD is connected to lead wires through splices, the lead wires leaving the nominal housing. A fastener tab extends away from the nominal body, and generally perpendicularly to the probe. The lead wires are anchored within a chamber, which is filled with a potting material.

A ball bearing has an outer race and an inner race A plurality of ball members are supported radially between the inner and outer races. A pair of bearing cage halves are placed at axial ends of the balls. The bearing cage halves are formed of a first relatively hard material, and have a plating of a softer material on some surfaces The bearing cage halves have pockets facing the balls and with the soft plating The bearing cage halves are riveted together along a contact surface, not including the soft plating. The rivets extend through an aperture in each of the bearing cage halves, not provided with the soft plating. The rivets have heads extending into a ditch, not provided with the soft plating. A rotor sub-assembly, a generator, and a method of maintaining a generator are also disclosed.

Ball bearing particularly for use in high speed generator

A vane liner for use in a vane pump has a vane liner body defining an inner bore for providing a cam surface in a vane pump. The cam surface has a suction opening formed through the body at one circumferential extent, and a discharge opening through the body at a distinct circumferential extent. A pre-pressurization opening extends through the body at a location upstream of an upstream end of the discharge opening, but spaced by at least 90 degrees from a downstream end of the suction opening. A vane pump incorporating the above-discussed liner is also claimed. Further, a vane pump is also disclosed and claimed having the spacing from the downstream end of the suction opening at least X degrees wherein X equals 360 divided by N, N being the number of vanes in the vane pump.
