Abstract: A dynamoelectric machine has at least one sheet metal end shield including a partial spherical bearing seating surface deformed therefrom and a set of keys also integrally deformed from the end shield so as to extend generally radially of the partial spherical bearing seating surface. A self-adjusting bearing includes a bearing surface interposed between a pair of opposite end portions of the bearing and extending generally circumferentially thereabout with the bearing surface being disposed in at least limited self-adjusting engagement with the partial spherical bearing seating surface. A set of keyways in one of the opposite end portions of the bearing extend generally radially thereof to intersect with the bearing surface and receive the keys deformed from the end shield in rotational displacement preventing engagement, respectively.

Abstract: A method of forming a bearing having a body of sintered powder metal. The bearing body includes a plurality of surfaces with interstices in the sintered powder metal defining a plurality of lubricant flow capillary paths through the bearing body communicating with the surfaces thereof, respectively. In this method, at least some of the sintered powder metal of at least one of the surfaces on the bearing body is mechanically worked with respect to the capillary paths communicating with the at least one surface, and the capillary paths communicating with the at least one surface are thereby at least restricted to a preselected degree limiting the porosity thereof generally at the at least one surface.

Abstract: A method of manufacturing a rotatable assembly adapted for use in a prime mover. The rotatable assembly includes a shaft having a peripheral surface along at least a part thereof and at least another component having an opening therethrough. In this method, a plurality of generally annular axially spaced apart ridges is deformed from the shaft, and the ridges are in part extended beyond the peripheral surface of the shaft. The opening of the other component is arranged generally circumferentially about at least some of the ridges in displacement preventing engagement therewith.A method of manufacturing a prime mover is also disclosed.

Abstract: A method is provided for assembling a device in a preselected assembly position onto a rotatable shaft of a prime mover with respect to an opening in an end plate of the prime mover through which the shaft extends so as to preclude contamination of a lubricant in a lubrication system of the prime mover communicated with the opening in the event the prime mover is operated in an environment in which a fluid imcompatible with the lubricant may be presented to at least one of the end plate and an exterior end section of the shaft extending beyond the opening.

Abstract: A rotatable assembly for use in a prime mover. The assembly has a shaft and at least one plurality of generally annular spaced apart ridges is integrally formed with the shaft so as to extend at least in part generally radially outwardly thereof. A thrust bearing device is disposed about the shaft in displacement preventing engagement with at least some of the ridges of the plurality thereof.A prime mover is also disclosed.

Abstract: A prime mover has a rotatable shaft with an exterior end section thereof adapted for driving an apparatus and for subjection to leakage flow from the apparatus of a fluid incompatible with a lubricant of a lubrication system in the prime mover to effect the lubrication of the shaft. An end plate on the prime mover has an opening extending therethrough in radially spaced relation with the shaft and communicating with the lubrication system, and means is provided for preventing the passage of the fluid and the lubricant through the opening.

Abstract: A method of assembling a dynamoelectric machine having a stationary member, a rotatable member, and a pair of means for rotatably supporting the rotatable member within the stationary member. In this method, beams are attached to the stationary member, and opposite end portions of the beams extend from the stationary member. The rotatable means is then mounted with the stationary member and the supporting means with one of the opposite end portions of the beams within means in one of the supporting means for receiving them. The receiving means is at least partially filled with molten metal which solidifies for interconnecting the one opposite end portion of the beams with the one supporting means, and the other of the supporting means is then secured to the other of the opposite end portions of the beams.
