摘要： A reliable brake rotor and wheel bearing assembly are proposed which make unnecessary adjustment of runout of brake rotor at the customer's factory. For runout of each of the mounting surface and back of the brake rotor itself, and runout of the side of the wheel mounting flange of the inner member to which is mounted the brake rotor, the maximum difference between the peaks of crests and troughs in each period of surface runout is restricted within a standard value, and the brake rotor is mounted to the wheel mounting flange, thereby eliminating the necessity of mounting of the brake rotor and adjustment of runout after mounting at the customer's factory to provide a reliable automotive wheel bearing assembly.

摘要： A vehicle wheel bearing apparatus with a back-to-back double row tapered roller bearing has an outer member integrally with a body mounting flange and double row outer raceway surfaces tapered open respectively axially inward and outward. An inner member include a wheel hub and an inner ring or an outer joint member of a constant velocity universal joint. The wheel hub has a wheel mounting flange and one inner raceway surface arranged oppositely to one of the double row outer raceway surfaces and a cylindrical portion. The inner ring or the outer joint member of a constant velocity universal joint are press fit onto the cylindrical portion and include the other inner raceway surface arranged opposite to the other raceway surface of the double row outer raceway surfaces. Double row tapered rollers are freely rollably held between the outer and inner raceway surfaces by cages. Seals are arranged in annular openings formed by the outer and inner members. The cages are formed of synthetic resin. Posts between pockets of the cages are arranged to be positioned radially inward of the pitch circle diameter of the tapered rollers. The width of an opening radially inward of each pocket is set so that each tapered roller is held within the pocket. The contacting tapered surfaces of the posts open radially outward so that the rollers do not fall out radially inward.

摘要： A vehicle wheel bearing apparatus has an outer member, an inner member and double row rolling elements. A wheel mounting flange is integrally formed on a driving side of the inner member for mounting a wheel via a brake rotor. Through apertures are formed on the wheel mounting flange. Hollow pins, having a chamfered portion, are press-fit into the through apertures. The brake rotor is formed with insert apertures to receive the pins, at positions respectively corresponding to the hub bolts and pins. The brake rotor can be temporarily mounted on the wheel mounting flange by inserting or press-fitting the chamfered end sides of the pins into the insert apertures.

摘要： To provide a wheel support bearing assembly in which the frictional resistance can be effectively reduced while effects of minimizing leakage of the filled lubricant and ingress of dust and muddy water from outside of the bearing assembly are secured, the wheel support bearing assembly includes an outer member 1, an inner member 2 positioned inside the outer member 1 with an annular working space defined between it and the outer member 1, and rows of rolling elements 3 accommodated within the annular working space and rollingly received in part within outer raceways 4 in the outer member 1 and in part within inner raceways 5 in the inner member 2. Opposite open ends of the annular working space are sealed by respective sealing members 7 and 8 which are secured to one of the outer and inner members 1 and 2. Each of those sealing members 7 an 8 has a plurality of elastic sealing lips 10a to 10c or 12a to 12c having their free ends oriented towards associated sealing surfaces 2c defined on the other of the outer and inner members 1 and 2, or 15aa and 15ba defined on a sealing contact member 15 secured to the other of the outer and inner members 1 and 2. Of those elastic sealing lips, the axially innermost sealing lips 10a and 12a function as a non-contact sealing lip that defines a respective gap of a size δ1 and δ2 sufficient to provide a non-contact sealing effect. The remaining sealing lips 10b, 10c, 12b and 12c function as a contact sealing lip.

摘要： In the capillary tube 22, the cross section of the outer surface is substantially square, and the cross section of the insertion hole 23 is substantially square. Sides La, Lb of the outer surface have high dimensional accuracy and the insertion hole 23 is made to allow two optical fibers 5, 6 to be inserted while adjoining each other and arranged in order therein. The phases of the outer surface and the insertion hole 23 are relatively offset with each other, so that angles &thgr;a, &thgr;b which the sides 23a, 23b of the insertion hole 23 form with flat surfaces 22a, 22b of the outer surface are acute angles of substantially 45°±0.5°. Consequently, the flat surface 22a becomes substantially parallel to the center line M that connects the centers of the cores 5a, 6a of the two optical fibers 5, 6 inserted in the insertion hole 23, and the flat surface 22b becomes substantially perpendicular to the center line M.
