20090074341 | Resin cage for ball bearing - It is a cage that is formed of a resin and that holds balls serving as rolling elements. The cage includes an annular base portion, and a plurality of claw portions that are formed to be arranged at constant intervals on the circumference of the base portion and to protrude therefrom. A pocket for accommodating the ball is formed between each pair of adjacent ones of the claw portions. In the resin cage for a ball bearing, thinning recesses are formed in end parts | 03-19-2009 |
20090154859 | Rolling bearing device for wheel - A rolling bearing device for a wheel includes: an inner member; an outer member disposed around an outer peripheral surface of the inner member via rolling elements; and a wheel mounting flange formed on an outer peripheral surface of the inner member or the outer member. A predetermined number of bolt holes are formed in a peripheral edge portion of the wheel mounting flange along a circumferential direction, and a shape between adjacent ones of the bolt holes is constituted by a straight line or a curved line located radially outwardly of a pitch circle diameter of the bolt holes in an outer shape of the wheel mounting flange. | 06-18-2009 |
20090252446 | Wheel rolling bearing assembly and manufacturing method thereof - A rolling bearing assembly for a wheel includes: an inner ring member in which an inner ring raceway surface is formed on an outer peripheral surface of the inner ring member; an outer ring member having a fitting tubular portion on the inboard side that is fitted into an attachment hole of a vehicle body member, and an outer ring raceway surface is formed on an inner peripheral surface of the outer ring member; a plurality of rolling elements disposed between the inner and outer ring raceway surfaces; and a cage that holds the plurality of rolling elements. The bore diameter B of the fitting tubular portion of the outer ring member is smaller than the diameter C of a circumscribed circle of the rolling elements. | 10-08-2009 |
20100210369 | WHEEL BEARING DEVICE AND MANUFACTURING METHOD THEREFOR - A wheel bearing device of the invention includes a flanged shaft member that includes a shaft portion to which a rolling bearing is assembled, a fitting shaft portion that is formed on one end side of the shaft portion and that is fitted to a center hole of a wheel, and a plurality of flange portions that extend radially outward on an outer peripheral surface located between the shaft portion and the fitting shaft portion and each of which has a bolt hole in which a hub bolt for fastening the wheel is arranged. Each flange portion is formed by side extrusion when a forged recess is formed at a center of an end surface of the fitting shaft portion by cold forging. | 08-19-2010 |
20100269347 | ROLLING BEARING SYSTEM FOR VEHICLES - The present invention provides a rolling bearing device for vehicles capable of detecting a change in magnetism with high accuracy. A rolling bearing device H for vehicles in accordance with the present invention includes a rolling bearing | 10-28-2010 |

20080258541 | Bearing Device for Wheel - A wheel bearing apparatus includes a roller bearing, an inner shaft having an outer circumferential surface to which an inner ring of the roller bearing is installed, a coupler ring attached to an end portion of the inner shaft, and a caulked portion provided in an end portion of the inner shaft so as to fix the coupler ring and the roller bearing to the inner shaft so as to be immovable in an axial direction of the inner shaft. An outer diameter of the coupler ring is set smaller than a diameter of a shoulder portion of the inner ring. Alternatively, a protruding portion is provided in any one of opposing end surfaces of the coupler ring and the inner ring, whereby the coupler ring is arranged away from a seal member. Accordingly, it is possible to avoid an interference of the coupler ring with the seal member. | 10-23-2008 |
20090003744 | Rotor for Use in Rotary Encoder and Wheel Rolling Bearing Assembly Including the Same - The invention seeks to provide a rotor for use in rotary encoder, which is increased in magnetic intensity and mechanical strength thereby achieving exact detection of rotation speed. | 01-01-2009 |
20100038958 | WHEEL SUPPORTING SYSTEM - An outer ring shaft portion which is extended integrally from an end face of an outer ring of a constant velocity joint is fittingly inserted into an inside hole in a hub shaft of a wheel hub, so that the wheel hub and the constant velocity joint are coupled to each other. Internal splines and external splines are formed on an inner circumferential surface of the inside hole in the hub shaft and an outer circumferential surface of the outer ring shaft portion in such a manner as to mesh with each other. Side face splines are formed on end face of the hub shaft and an end face of the outer ring of the constant velocity joint. The wheel hub and the constant velocity joint are connected together in such a manner that torque can be transmitted therebetween. | 02-18-2010 |
20100046873 | SEALING DEVICE AND ROLLING BEARING APPARATUS - A sealing device is mounted in an annular space defined between an inner member and an outer member which rotate relative to each other. The sealing device includes a slinger which has a cylindrical portion which is press fitted on or in one of the inner member and the outer member and an annular plate portion, and a seal main body which has a core metal having a cylindrical portion which is press fitted in or on the other of the inner member and the outer member and an annular plate portion and a seal member fixed to the core metal. A lip for closing a space between the annular plate portion of the slinger and the cylindrical portion of the core metal is provided on the slinger or the seal main body. | 02-25-2010 |
20100054644 | WHEEL ROLLING BEARING UNIT - A cover member includes a metallic cover main body having a lid portion and a cylindrical portion and an elastic covering material which covers outer circumferential surfaces of the lid portion and the cylindrical portion. In a state resulting before the cover member is fitted in a one end side opening of an outer ring of a rolling bearing, of the elastic covering material, an outside diameter dimension of a cylindrical portion elastic layer which covers the outer circumferential surface of the cylindrical portion is set to be larger than an inside diameter dimension of an inner circumferential surface of the one end side opening. In an attached state in which the cover member is fitted in the outer ring, the cylindrical portion elastic layer is elastically compressed to thereby be brought into close contact with the inner circumferential surface of the one end side opening of the outer ring. | 03-04-2010 |
