384467000 | Cooling by lubricant | 11 |
20090148088 | Lubricator for Rolling Bearings - The object is to provide a lubricator for rolling bearings which is also capable of cooling the inner ring and which can reduce the resistance of cooling oil when the oil is agitated during high-speed rotation of the bearing. | 06-11-2009 |
20110262068 | AXLE BEARING LUBRICATING AND COOLING SYSTEM - An axle bearing lubricating and cooling system includes a shaft and an axle bearing that has an inner race fixedly mounted around the shaft, an outer race and a plurality of movable members movably set in between the inner race and the outer race, a casing fixedly connected with the outer race of the axle bearing for enabling two distal ends of the shaft to extend out of the casing, casing having a fluid inlet for guiding a cooling fluid from an external cooling fluid source through the gap in between the outer race and inner race of the axle bearing and a fluid outlet located for guiding the cooling fluid out of the casing, and an impeller rotatable with the shaft for forcing the cooling fluid out of the axle bearing toward the fluid outlet. | 10-27-2011 |
20130223779 | ROLLER BEARING - A rolling bearing assembly in which the number of components is reduced, and a high speed operation can be enabled with an increase of the stirring resistance being avoided by a sufficient discharge of lubricant oil and with an increase of temperature within the bearing assembly being suppressed. The rolling bearing assembly includes a pair of raceway rings, which are inner and outer rings, a plurality of rolling elements interposed between the inner and outer rings and a retailer for retaining the rolling elements. Each of the inner and outer rings is provided with an axially extending raceway ring extension portion and an oil supply and drainage mechanism for supplying a lubricant oil, which concurrently serves as a bearing cooling medium, to the bearing assembly and for discharging the lubricant oil to outside of the bearing assembly is provided in the raceway ring extension portion. | 08-29-2013 |
20140334757 | ROLLING BEARING DEVICE - A rolling bearing device which may include: a pair of raceway rings including an inner ring and an outer ring, a plurality of rolling elements interposed between respective raceway surfaces of the inner and outer rings, a retainer to retain the rolling elements; an oil supply and discharge mechanism to supply a lubricant oil, which concurrently serves as a bearing cooling medium, into the inside of the bearing device and to discharge the lubricant oil to the outside of the bearing device; and a ring shaped shake-off collar portion disposed in the vicinity of an end portion of an outer diametric surface of the inner ring so as to protrude radially outwardly, wherein the lubricant oil supplied from the oil supply and discharge mechanism and provided for lubrication within the bearing device is, after being received by the shake-off collar portion, shaken-off in a direction radially outwardly by the effect of a centrifugal force developed as a result of an inner ring rotation. | 11-13-2014 |
20140369635 | TAPERED ROLLER BEARING AND POWER TRANSMISSION DEVICE USING TAPERED ROLLER BEARING - A tapered roller bearing includes: an inner ring; an outer ring provided on an outer peripheral surface of the inner ring via an annular space so as to be disposed on the same center line as the inner ring; a plurality of tapered rollers rollably disposed in the annular space; and a cage retaining the plurality of tapered rollers. The tapered roller bearing is configured such that: liquid lubricant flows through the annular space; and among the inner ring, the outer ring, the tapered rollers, and the cage, at least one rotating component configured to rotate at the time of bearing rotation is provided with a vaporization promotion mechanism configured to decrease a pressure of the lubricant at the time of bearing rotation so that the pressure of the lubricant reaches a saturation vapor pressure at which the lubricant changes from a liquid phase to a vapor phase. | 12-18-2014 |
20150316106 | BEARING RACEWAY HEAT DISTRIBUTION USING HEAT PIPES - A system and method to cool a bearing. The system includes a heat pipe extending through a thickness of an inner ring of the bearing from a first surface to an opposing second surface and a cooling lubricant in fluid communication with the first surface. The method includes exposing the first surface of the roller bearing to lubricant and transferring heat energy through the heat pipes. | 11-05-2015 |
20150377295 | MACHINE ARRANGEMENT - A machine arrangement comprising a crankshaft which is supported by at least one roller bearing including bearing rings and roller elements between the bearing rings, wherein the roller bearing is connected with a device for delivering of a lubricant to the area of rolling contact between the bearing rings and the roller elements. To improve the supply of lubricant to the roller bearing and to supply the right amount of lubricant in dependence of the temperature of the roller bearing, the device for delivering of the lubricant comprises a lubricant reservoir and a flow path from the lubricant reservoir to the area of rolling contact, wherein a valve element is arranged in the flow path for controlling at least one of a flow of lubricant and a pressure of lubricant in dependence of the temperature of at least one of the roller bearing and the valve element. | 12-31-2015 |
20160047422 | BEARING ASSEMBLY WITH LUBRICANT/COOLANT PASSAGES - A bearing assembly for mounting relative to a housing is provided that includes a bearing ring, a plurality of rotational members, and a bearing ring baffle. The bearing ring has a housing surface, an inner radial surface, a first axial end, a second axial end, and a plurality of channels disposed in the first axial end of the ring. The bearing ring baffle has a housing surface, an inner radial surface, a first axial end, a second axial end, and a plurality of fins extending out from the second axial end of the baffle. The fins and channels are configured to mate with one another and to create at least one passage there between, and the passage is con figured for the passage of lubricant there through. | 02-18-2016 |
