20100027929 | LUBRICATING SYSTEM, BEARING UTILIZING THE SYSTEM, UNIVERSAL JOINT UTILIZING THE SYSTEM, AND PROCESS FOR PRODUCTION THEREOF - It is an object of the present invention to provide a lubricating system that improves the force of retaining a lubricating component of a foam lubricant, minimizes an exudation amount of the lubricating component caused by deformation of the foam lubricant, is excellent in initial lubrication, has a long life, has a low cost, and is excellent in the productivity thereof; a bearing utilizing the lubricating system; a universal joint utilizing the lubricating system; and a process for the production thereof. A lubricating system includes a foam lubricant ( | 02-04-2010 |
20100247013 | Retainer for roller bearing, and rolling bearing - A retainer for a rolling bearing, which is used for a food machine or a vacuum apparatus, containing an increased amount of a lubricating oil and enhancing a use efficiency of the lubricating oil and rolling bearing is described. The retainer consists of a molding, of a synthetic resin composition, which holds a rolling element of a rolling bearing. The molding is composed of a resinous porous article having an interconnected hole porosity not less than 30% and a lubricating oil which impregnates the resinous porous article. The resinous porous article has an interconnected hole are formed by molding a resin containing a pore-forming substance having a melting point higher than that of the resin and can be used as a food material, and by extracting said pore-forming substance from the molding with a solvent which dissolves the pore-forming substance and does not dissolve the resin. | 09-30-2010 |
20100316317 | Bearing Having a Porous Element for Accommodating Lubricant - The invention relates to a bearing element | 12-16-2010 |
20110255816 | BEARING ELEMENT WITH POROUS ELEMENTS IN RING SEGMENTS - The invention relates to a bearing element with rolling bodies which are arranged in the peripheral direction between an inner ring and an outer ring disposed concentrically to the inner ring, particularly with a cage for holding the rolling bodies, the bearing element comprising porous elements along the peripheral direction in individual ring segments for receiving lubricant. | 10-20-2011 |
20120301065 | ROLLING BEARING LUBRICATION STRUCTURE AND ROLLING BEARING - A lubrication structure for a rolling bearing assembly of low manufacturing cost, high speed and the environment-friendly is provided. An inclined surface portion is provided in an outer diametric surface of an inner ring of the bearing assembly, and a grease tank having a grease reservoir is arranged adjacent to an outer ring of the rolling bearing assembly. A base oil transfer medium for moving a base oil in the grease by capillary phenomenon is provided within the grease reservoir, and one end thereof contacts the inclined surface portion. Accordingly, the base oil within the grease reservoir adheres to the inclined surface portion through the base oil transfer medium, and the base oil adhering to the inclined surface portion is supplied to the bearing assembly utilizing surface tension of the base oil and the flow of the base oil induced upon rotation of the inner ring. | 11-29-2012 |
20140363113 | ROLLING-ELEMENT BEARING - A rolling-element bearing includes a first rolling-element bearing ring configured to be mechanically connectable to a stationary component, a second rolling-element bearing ring configured to be mechanically connectable to a rotating component and at least one porous body disposed between the first rolling-element bearing ring and the second rolling-element bearing ring and configured to hold a lubricant. The at least one porous body is mechanically coupled to the second rolling-element bearing ring and configured such that during rotation of the second rolling-element bearing ring the at least one porous body substantially rotates with the second rolling-element bearing ring, and, due to this rotation, releases an amount of the lubricant. The at least one porous body is further configured to absorb at least a portion of the released amount lubricant when the second rolling-element bearing ring is stationary. | 12-11-2014 |
20140363114 | ROLLING ELEMENT BEARING CAGE SECTION, ROLLING-ELEMENT BEARING CAGE, AND ROLLING-ELEMENT BEARING - A rolling-element bearing cage section for a rolling-element bearing is configured to guide at least one rolling element between a first and a second rolling-element bearing ring of the rolling-element bearing. The rolling-element bearing cage section is configured to partially or completely receive the at least one rolling element prior to installation in the rolling-element bearing. The rolling-element bearing cage section includes a porous material adapted to absorb a lubricant and release the lubricant as a result of a centrifugal force acting on the lubricant during rotation of the rolling-element bearing cage section, thus allowing a liquid lubricant to be used in a rolling-element bearing without the need for complex seals. | 12-11-2014 |
20150030274 | ROLLER BEARING HAVING INTERNAL LUBRICATION - The rolling bearing comprises an inner ring, an outer ring, at least one row of rolling elements disposed between raceways provided on the rings, and an annular housing inside which at least one of the rings is arranged. The ring provides two parts and each of the two parts delimits with the housing a closed space inside which a lubricant is located. The rolling bearing further comprises passage means for the lubricant to pass from the closed spaces to the raceways. | 01-29-2015 |
20160123398 | BEARING ASSEMBLY WITH LUBRICATION CARTRIDGE - A bearing assembly comprises a rolling element bearing having an inner ring, an outer ring and a set of rolling elements arranged in a bearing cavity between the inner and outer rings. A first grease is provided in the bearing cavity, which has a first thermal bleed rate at a specific reference temperature. The bearing assembly further comprises a grease cartridge, arranged at an axial side of the bearing cavity, whereby the cartridge has axially extending passageways that open into the bearing cavity, and whereby at least some of the passageways are filled with a second grease. The second grease has a second thermal bleed rate at the specific reference temperature which is lower than that of the first grease. | 05-05-2016 |
