20080240642 | Rolling bearing unit for wheel and method for manufacturing the same - In a rolling bearing unit for a wheel of the invention, a first inner ring side raceway which confronts an outer ring side raceway formed on an inner circumferential surface of an outer ring is formed on an outer circumferential surface of a hub wheel, and a second inner ring side raceway is formed on an outer circumferential surface of an inner ring shaft portion. The inner ring shaft portion is made up of a large diameter shaft portion which is formed on an outer circumferential surface of the second inner ring side raceway and a small diameter shaft portion which is inserted into a shaft fitting hole in the hub wheel in such a manner as to pass therethrough. In addition, the inner ring shaft portion is connected to the hub wheel by forming a calking portion by calking an end portion of the small diameter shaft portion. | 10-02-2008 |
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 |
20090324154 | WHEEL BEARING APPARATUS - A bearing apparatus includes an inner ring including a flange a tubular portion which has an end face; an outer ring coupled to the inner ring through a plurality of rolling elements; and a drive force-receiving portion including a plurality of teeth which is radially formed on the end face in a direction intersecting an axial direction. A surface of the each teeth is coated by a coating. | 12-31-2009 |
20120267944 | MACHINING TOOL FOR VEHICLE HUB UNIT AND VEHICLE HUB UNIT - In a machining tool, multiple tooth forming portions for plastically forming spline teeth on an axial end face of a vehicle hub unit, the axial end face facing inward in the vehicle lateral direction, are formed in a circular pattern about the central axis of the machining tool. In the machining tool, a rounded-portion forming portion is formed to form a rounded portion between a tooth flank and a top land of each spline tooth, and the radius of the rounded-portion forming portion gradually changes in the radial direction about the central axis. | 10-25-2012 |
20130229046 | WHEEL SUPPORT DEVICE - A rotary ring of a hub unit has an annular first end face on one side in the axial direction, and an outer ring of a joint has an annular second end face on the other side in the axial direction. Outer splines are formed in a radially outer-side region of the first end face and outer splines are formed in a radially outer-side region of the second end face. The outer splines of the first end face and the outer splines of the second end face mesh with each other. Inner splines are formed in a radially inner-side region of the first end face and inner splines are formed in a radially inner-side region of the second end face. The inner splines of the first end face and the inner splines of the second end face mesh with each other. | 09-05-2013 |
20130229047 | WHEEL SUPPORT DEVICE - A rotary ring of a hub unit has an annular end face on one side in the axial direction, and a tapered outer periphery in a radially outer region of the end face. The diameter of the tapered outer periphery increases toward the other side in the axial direction. An outer ring of a joint has an annular end face on the other side in the axial direction, and had a tapered inner periphery in a radially outer region of the end face. The diameter of the tapered inner periphery increases toward the other side in the axial direction, and the tapered inner periphery faces the tapered outer periphery. Splines are formed in the tapered outer periphery and splines are formed in the tapered inner periphery, and the splines of the tapered outer periphery and the splines of the tapered inner periphery mesh with each other. | 09-05-2013 |
20130230351 | SPLINE FORMING METHOD FOR HUB UNIT, HUB UNIT, SPLINE FORMING METHOD FOR JOINT, AND JOINT - Splines, which are to be meshed with a joint that transmits torque to a rotary ring of a hub unit, are formed in a side face of the rotary ring, the side face being on one side of the rotary ring in the axial direction. Spline grooves are formed in the side face by subjecting the side face to broaching. | 09-05-2013 |
20140035349 | HUB UNIT - A hub unit of the present invention includes a cap that covers an opening of a pilot portion, and the cap includes a cap body formed in a disc shape, and a cylindrical portion extending in an axial direction from an outer periphery of the cap body. The cap is removably attached to the pilot portion by screwing an external thread portion formed on an outer periphery of the cylindrical portion of the cap, to an internal thread portion formed on an inner periphery of the pilot portion. | 02-06-2014 |
20140077473 | VEHICLE BEARING APPARATUS - A first side-face spline of a hub spindle and a second side-face spline of a constant velocity joint each has a tooth tip formed by tip tilted surfaces tilted from tooth flanks constituting a tooth chevron, an internal angle of the tooth tip is set to be less than 180 degrees, and a tooth tip-side perpendicular distance, which is a perpendicular distance between a tooth tip virtual intersection and a first virtual plane is set larger than a bottom land-side perpendicular distance, which is a perpendicular distance between a bottom land virtual intersection and a second virtual plane. | 03-20-2014 |
20140175862 | VEHICLE BEARING DEVICE - A hub of a vehicle bearing device has a cylindrical portion and a flange portion. The flange portion has a pin hole formation portion, a reference position intermediate portion, separate position intermediate portions, and build-up portions. The reference position intermediate portion is formed between bolt hole formation portions. The first separate position intermediate portion is formed between bolt hole formation portions. The second separate position intermediate portion is formed between bolt hole formation portions. The pin hole formation portion is formed at the reference position intermediate portion, and has a hub side pin hole. A pin for fixing the hub and a brake rotor to each other is inserted into the hub side pin hole. The build-up portions are formed on the separate position intermediate portions, and are balanced in terms of weight with the pin-hole formation portion. | 06-26-2014 |
