| 20090274407 | ROLLING BEARING FOR TENTER CLIP - The present invention provides a rolling bearing, for a tenter clip, which is capable of restraining deterioration of a sealing member even though the sealing member contacts ester oil, and is excellent in reliability and durability at high temperatures. A periphery of an outer ring of the rolling bearing for use in the tenter clip of a film-stretching apparatus is lubricated with the ester oil. In the sealing member which covers openings disposed at both axial ends of an inner ring and the outer ring of the rolling bearing, at least a portion of the sealing member which contacts the ester oil is made of (A) a fluororubber molding of a vulcanizable fluororubber composition which comprises a copolymer containing tetrafluoroethylene (TFE), propylene, and a to-be-crosslinked monomer consisting of unsaturated hydrocarbon, having two to four carbon atoms, in which a part of hydrogen atoms is substituted with fluorine atoms or (B) a fluororubber molding of at least one fluororubber composition selected from a vulcanizable fluororubber composition containing a TFE-propylene binary copolymer and a vulcanizable fluororubber composition containing a vinylidene fluoride-TFE-propylene ternary copolymer. | 11-05-2009 |
| 20110075960 | AXLE SHAFT COVER PLATE WITH BEARING ASSEMBLY - A cover plate for a drive assembly that includes a bearing housing having a bearing cavity, a thrust bearing axially disposed within the bearing cavity that includes a cup, cone and plurality of rollers disposed between cup and cone raceways, a thrust plate with an axle engaging surface disposed perpendicular to a central axis and coupled for rotation to the cone. The cover plate may be connected to a final drive housing of a final drive that includes a plurality of gears operatively connected to an axle shaft, the end of the axle shaft positioned to rotationally engage the thrust plate and cone. | 03-31-2011 |
| 20110274383 | Bearing, In Particular for a Wind Turbine - A bearing, in particular for a wind turbine, is provided. The bearing has a standing inner ring, an outer ring movable around the inner ring, lubricated rollers in a cage, arranged between the inner ring and the outer ring. The bearing includes a device for draining oil from a top region of the standing inner ring. | 11-10-2011 |
| 20110293214 | Rolling Bearing and Thrust Bearing Assembly Comprising said Rolling Bearing - The invention relates to a rolling bearing | 12-01-2011 |
| 20120195542 | Oil-Sealed Mud Motor Bearing Assembly With Mud-Lubricated Off-Bottom Thrust Bearing - A bearing assembly for a mud motor has a mandrel rotatably disposed within a cylindrical housing, with a rolling-element thrust bearing disposed within an oil-sealed annular chamber between the mandrel and the housing, for resisting on-bottom axial thrust loads. Off-bottom axial thrust loads are resisted by a mud-lubricated thrust bearing assembly located above the oil-sealed chamber. The lower end of a drive shaft adapter coupled to the mandrel is used to provide an upper load-transferring shoulder for the off-bottom thrust bearing, with a lower load-transferring shoulder being provided in association with the housing. The upper and lower shoulders come into mating contact under off-bottom thrust loading, with the upper shoulder rotatable (with the mandrel) relative to the lower shoulder. | 08-02-2012 |
| 20140093201 | APPARATUS AND METHODS OF SELF COOLING A VERTICAL MOTOR THRUST BEARING - Vertical motors having a thrust bearing and an oil deflector positioned in an oil sump in which the thrust bearing is located are disclosed. Oil flowing through the thrust bearing may be spread across the oil deflector and directed down along an inside surface of a wall of the oil sump to allow the oil to cool. The oil deflector may be polished sheet metal. In some embodiments, a plurality of fins may be arranged around an outside surface of the wall to provide additional heat exchange. A fan may additionally be provided to direct air flow between the plurality of fins to further facilitate the heat exchange. Methods of cooling a thrust bearing in a vertical motor are also provided, as are other aspects. | 04-03-2014 |
| 20150104127 | LUBRICATION OF POWER TRANSFER COMPONENTS - An apparatus for lubricating power transfer components is described. The apparatus includes a first shaft enclosed by a housing with a main cavity, and an inboard bearing and an outboard bearing supporting the first shaft. An inboard bearing cavity and an outboard bearing cavity surround, respectively, the inboard and outboard bearings. Lubrication fluid flows from an entrance port in the housing, through a flow passage within a wall of the housing to the inboard bearing cavity, through a flow passage within the first shaft from the inboard bearing cavity to the outboard bearing cavity, and through an overflow port in a wall of the outboard bearing cavity. A second shaft provides rotational power to the first shaft (e.g., via an idler gear). A lubrication deflector, such as a frustoconical deflector, surrounds a portion of a second shaft and extends into the main cavity of the housing. | 04-16-2015 |
| 20160138653 | BEARING ASSEMBLY WITH LUBRICATION CARTRIDGE - A bearing assembly comprising a rolling element bearing having a first row of rolling elements arranged in a first bearing cavity between a first inner raceway and a first outer raceway of the bearing, and having a second row of rolling elements arranged in a second bearing cavity between a second inner raceway and a second outer raceway of the bearing. The assembly further comprises an annular grease cartridge arranged between the first and second rows of rolling elements. The annular grease cartridge is at least partly formed from a honeycomb structure having axially extending passageways filled with a grease lubricant, wherein at least some of passageways are open towards the first and second bearing cavities. | 05-19-2016 |
