An eccentric shaft assembly includes a first eccentric shaft including an interior surface forming a recess therein, an exterior surface, at least one first fluid inlet extending between the interior surface and the exterior surface, at least one first fluid outlet extending between the interior surface and the exterior surface. The eccentric shaft assembly further includes a second eccentric shaft disposed in the recess of the first eccentric shaft that includes a second bearing surface engaging the first bearing subassembly opposite the first bearing surface and at least one first fan blade for rotating about an axis of rotation to force a fluid to enter the recess through the first fluid inlet(s) and exit the recess through the first fluid outlet(s), to lubricate and/or cool a bearing subassembly disposed between the first eccentric shaft and the second eccentric shaft.

The bearing structure includes an insertion member, which is inserted through a pin hole (insertion hole) of a bearing housing (housing) in a direction intersecting an axial direction of a shaft, has one end side inserted between a pair of radial bearing surfaces of a main body portion and another end side inserted through the insertion hole, and has a through hole passing from one end to another end.

A rolling bearing device includes a rolling bearing partially submerged in lubricating oil stored in an oil pocket provided in a vertically lower portion of a housing to a level corresponding to a part of an annular space, an annular shielding member, and an annular seal component. The shielding member has an oil drain portion for drainage of the lubricating oil in the annular space to the outside of the rolling bearing at a vertical level above an oil level of the lubricating oil stored in the oil pocket when the rotary shaft is stationary. The oil drain portion has an inclined groove having an inclined surface inclined away from the rolling bearing and an opening provided in an outer end portion at a distal end of the inclined surface. The inclined groove is tapered toward a vertical top of the shielding member when viewed in the axial direction.

An oil bath type bearing device which supports a rotating shaft rotating around an axis the bearing device is provided. The oil bath type bearing device includes a plurality of bearing pads which are arranged at intervals in a circumferential direction along an outer peripheral surface of the rotating shaft, an annular carrier ring which supports the plurality of bearing pads from an outer peripheral side and in which an oil supply hole through which a lubricant is supplied is formed, and a casing which covers the carrier ring from the outer peripheral side and holds the lubricant between the rotating shaft and the casing. The oil supply hole penetrate the carrier ring from the outer peripheral side to an inner peripheral side and extends toward a rear side in a rotational direction of the rotating shaft as the oil supply hole goes radially inward with respect to the axis.

A wheel case for a vibrating device for vibrating aggregate material includes a housing configured to contain a quantity of lubricating oil and a wheel positioned in the housing and mounted to a shaft of the vibrating device. The wheel includes: an inwardly facing side; an outwardly facing side; an eccentric weight mounted to the inwardly facing side or the outwardly facing side; and a plurality of bearings positioned in an annular bearing channel configured to permit the wheel to rotate about a spindle of the shaft. The wheel case also includes a dam mounted to the wheel at least partially covering the annular bearing channel, positioned such that the lubricating oil collects in the annular bearing channel during rotation of the wheel, and such that the collected lubricating oil remains in the annular bearing channel when rotation of the wheel ceases.

A bearing housing for a flow machine includes a bearing axis, a bearing chamber, a lubricant chamber and internal cooling fins. The bearing chamber is configured to receive a bearing. The lubricant chamber is configured to receive a lubricant. The lubricant chamber and the bearing chamber are in flow communication via an opening. The lubricant chamber includes a wall portion configured to dissipate heat to the environment, and the wall portion has an inner surface directed towards the lubricant chamber and an outer surface directed towards the environment. The internal cooling fins are arranged at a part of the inner surface.

A bearing chamber configuration that favorably directs the flow of oil/air mixture inside the bearing chamber of a gas turbine engine is disclosed. The bearing chamber includes an annular baffle surrounding a rotatable shaft. The baffle comprises an annular groove facing radially inwardly and a first radially-inner annular surface extending axially from a first side of the annular groove. The first radially-inner annular surface of the baffle cooperating with the shaft to define a first space inside the bearing chamber and adjacent the seal. The first space is circumferentially uniform.

The purpose of the present disclosure is to provide a thrust bearing cooling device which can improve the cooling efficiency of a thrust bearing. A thrust bearing cooling device comprising: a fluid storage tank in which a thrust bearing is installed and a fluid is stored, an outer surface of the fluid storage tank being exposed to external air; and at least one heat exchange fin provided in the fluid storage tank.

A bearing system includes bearing unit and a lubrication system. The bearing unit includes an outer race, a plurality of internal rotating components, and an inner race. The lubrication system includes an injector for delivering a stream of lubrication to the plurality of rotating components to withdraw heat generated and lubricate the bearing unit during operation of the bearing system.
