A rotating machine includes a housing and a first bearing received in the housing. The rotating machine also includes a shaft supported by the first bearing. The shaft defines a central axis that extends in a longitudinal direction. The rotating machine also includes at least one duct radially interior to the outer diameter of the shaft. The duct includes an inlet port and a radial outlet port that are in fluid communication with one another. The inlet port is configured to receive air and the radial outlet port is configured to discharge the air. The rotating machine also includes an air mover longitudinally disposed between the first bearing and the inlet port of the duct. The air mover creates an area of air pressure at the radial outlet port that is less than an air pressure at the inlet port.

A bearing assembly for an electrical generator includes a frame, a bearing liner, a bearing and a non-metallic ring. The frame is configured to connect with a housing of the electrical generator. The bearing liner is connected with the frame. The bearing is received in the bearing liner. The non-metallic ring is interposed between the bearing liner and the bearing.

Electrical generator and a bearing assembly for an electrical generator

A bearing assembly for an electrical generator includes a frame, a bearing liner and a ring. The frame is configured to connect with a housing of an electrical generator. The frame includes a frame opening and is made from a first material. The bearing liner connects with the frame. The bearing liner is made from a second material, which is dissimilar from the first material. At least a portion of the bearing liner passes through the frame opening. The ring surrounds the bearing liner. The ring contacts the frame and the bearing liner and maintains a clearance between the portion of the bearing liner passing through the frame opening and the frame.

Bearing assembly for electrical generator

An electro-mechanical fuse integrated into the enclosure of a bearing assembly of a generator or like component. Under normal operation, the electro-mechanical fuse provides continuity through a bearing sensing circuit. However, ball cage damage causes the fuse to open and, in turn, the bearing sensing circuit indicates bearing wear. Thus, damage to other generator components is greatly reduced because the generator is removed for maintenance in a timely manner.

Bearing enclosure with integrated wear detection

A dynamo electric machine for an aircraft gas turbine engine includes a housing supporting a stator of the dynamo electric machine, a rotor assembly rotatably mounted in the housing and including an elongate hollow rotor shaft, a main shaft for connection at one end to the associated gas turbine engine assembly, said main shaft extending coaxially within said hollow rotor shaft, and a sleeve-like member of electrically insulating material between said rotor shaft and said main shaft, said sleeve-like member providing an electrically insulating driving connection between said main shaft and said rotor shaft whereby said main shaft and said rotor shaft rotate together.
