| 20090046965 | Lubricating device for rolling bearing - A lubricating device for a rolling bearing includes a lubricating oil introduction member ( | 02-19-2009 |
| 20110007991 | SYSTEM AND METHOD FOR ISOLATING A ROLLING-ELEMENT BEARING - Lubrication fluid is discharged through an axial gap between a outer bearing race and a bearing housing from an enclosed volume bounded in part by a forward surface of the outer bearing race that is axially slideable within the bearing housing so as to provide for changing the axial gap. The pressure in the enclosed volume is automatically controlled responsive to an axial force on outer bearing race by an axial position of the outer bearing race that determines a size of the axial gap, so as to provide for increasing the pressure responsive to increasing axial force over at least a portion of an operating range. The lubrication fluid in the axial gap provides for isolating axial vibrations of the outer bearing race relative to the bearing housing. | 01-13-2011 |
| 20120177314 | RETENTION OF BALL BEARING CARTRIDGE FOR TURBOMACHINERY - An assembly for a turbocharger includes a ball bearing cartridge, a center housing with a bore, a turbine end counterbore and a compressor end surface that includes a recess, and a compressor backplate with an axial extension configured to fit into the recess where the counterbore and the backplate define, at least in part, an axial length of a bearing cartridge chamber. Various other devices, assemblies, etc., are also disclosed. | 07-12-2012 |
| 20100202720 | ROLLING BEARING DEVICE - To provide a rolling bearing device designed to accomplish a stabilized retention of the retainer during a high speed rotation, to avoid a direct contact between guide surfaces and to reduce the power loss between retainer guide gaps, the rolling bearing device includes a rolling bearing unit having rolling elements retained by an annular retainer and intervening between raceways of inner and outer rings, and a nozzle member provided proximate to the outer ring. The nozzle member is provided with an annular collar portion inserted in a bearing space delimited between the inner ring and the outer ring and having a nozzle hole. This collar portion has an outer diametric surface in the form of a retainer guide surface, and an inner diametric surface of the retainer is guided by this retainer guide surface. | 08-12-2010 |

| 20100158422 | ROLLER BEARING - An inner ring is formed with an oil hole extending through a part between an inner ring raceway surface and an inner peripheral face thereof, and configured to force out grease, which has been supplied to an area between the inner ring raceway surface and an outer ring raceway surface, to the inner peripheral face in accordance with rolling of cylindrical rollers. The inner peripheral face of the inner ring is formed with a plurality of V-shaped inclined grooves configured to guide the grease, which has been forced out to the inner peripheral face of the inner ring through the oil hole, to opposite end portions of the inner peripheral face in an axial direction of the inner ring. | 06-24-2010 |
| 20090028483 | Double row ball bearing - The large diameter cage has an asymmetric shape, a diameter (discharge diameter) of which close to an opening is larger than a diameter (inflow diameter) close to the small diameter cage, and the small diameter cage has a symmetric shape, in which a diameter (inflow diameter) of which close to an opening is equal to a diameter (discharge diameter) close to the large diameter cage. | 01-29-2009 |
| 20080310781 | Method for Lubricating a Rolling Element Bearing by Means of an Ultra Low Viscosity Volatile Fluid, and Bearing Arrangement - A method for lubricating a rolling element bearing by an ultra low viscosity volatile fluid comprises injecting a liquefied fluid flow into the bearing, lubricating rolling contacts between the rings and the rolling elements of the bearing by the liquefied fluid, providing a flow restriction for the liquefied fluid so as to maintain at least part of the fluid at a pressure which is above the evaporation pressure which is defined by evaporation of the fluid at the temperature or temperatures which prevail(s) in the bearing. | 12-18-2008 |
| 20090129714 | Roller bearing device and method of lubricating roller bearing - A bearing device includes a lubricating device that supplies a lubricant to a first lubricating path when a rotating speed of an inner ring member is detected to be no more than a predetermined speed and supplies the lubricant to the first lubricating path and a second lubricating path when the rotating speed of the inner ring member is detected to be higher than the predetermined speed, the lubricating device including a changeover valve that controls a supply of the lubricant to the first and second lubricating paths according to the rotating speed of the inner ring member. | 05-21-2009 |
| 20090175569 | Bearing apparatus - A bearing apparatus includes: two split outer ring halves which includes outer ring raceway surfaces and are disposed within a supporting hole of the housing, respectively; and a plurality of rollers which are disposed on respective inner surfaces of the both split outer ring halves and supports a shaft. Each of the two split outer ring halves includes an oil hole penetrating the split outer ring half in a radial direction thereof and an oil groove formed on an outer diameter surface of the split outer ring half along a circumferential direction thereof to allow the oiling passage and the oil holes to communicate with each other. Each of the oil holes is disposed at a position located at an angle of within 45° from the joint surface of the split outer ring halves in an opposite direction to a rotating direction of the shaft. | 07-09-2009 |
| 20120155793 | BEARING ARRANGEMENT FOR HIGH-SPEED SHAFTS OF MACHINES - A bearing arrangement for high-speed shafts of machines, such as rotor shafts of turbochargers. The bearing arrangement has a bearing housing that has at least one oil feed line and in the housing at least one bearing is installed. The bearing guides the shaft at least radially. The bearing has a ring with at least one oil bore. The ring forms an annular gap with the bearing housing. The bearing is a single-row rolling contact bearing, in which the shaft is guided directly or via an inner ring, preferably a two-part inner ring, and the ring is an outer ring of the rolling contact bearing. | 06-21-2012 |
| 20120189235 | BEARING RACE FOR A ROLLING-ELEMENT BEARING - A bearing race for a rolling-element bearing, the race comprising: a circumferential channel which defines a raceway, wherein the raceway comprises a base portion and first and second side portions; and an oil scavenge passageway extending through the race from a boundary between the base portion and the first and/or second side portions of the raceway to an external surface of the race. | 07-26-2012 |
