摘要： The present invention provides a hub bearing, made of carbon steel for machine structural use, which has a long life even in a strict lubricating condition by improving the resistance to peeling starting from the surface. A grease for the hub bearing contains a base oil, a thickener, and an organozinc compound which is at least one compound selected from dithiozinc carbamate and dithiozinc phosphate. The base oil is a mineral oil or a mixed oil of a mineral oil and a synthetic hydrocarbon oil. The thickener is a urea compound shown by the following formula (1) and is contained at 1 to 40 mass % for the entire grease. The grease for the hub bearing is enclosed in the hub bearing. (In the formula (1), R 2 indicates an aromatic hydrocarbon group having 6 to 15 carbon atoms, and R 1 and R 3 indicate at least one hydrocarbon group selected from an alicyclic hydrocarbon group and an aromatic hydrocarbon group.)

摘要： There is provided a method capable of producing a wheel-supporting rolling bearing unit at low cost. In an event of producing a wheel-supporting rolling bearing unit (1), a cylindrical portion (11) formed in an axial end portion of a hub ring (2) is inserted through an inner ring (3), swing caulking is performed by pressing a die (23) against a tip end portion of the cylindrical portion (11) protruding to an axial end portion side more than the inner ring (3), and an axial end surface (3a) of the inner ring (3) is held by a caulked portion (12) formed by caulking and expanding the tip end portion of the cylindrical portion (11) radially outward. In such a way, the inner ring (3) and the hub ring (2) are fixed integrally witch each other. At this time, a swing angle of the swing caulking is set at 15 degrees or more to 30 degrees or less.

摘要： A bearing device for a wheel, in which circumferential play is minimized and in which a hub ring and an outer joint member of a constant velocity universal joint can be connected with excellent workability. Axially extending projections (35) are formed on either one of the outer diameter surface of a shaft (12) of the outer joint member and the inner diameter surface (37) of a hole (11) of the hub ring (1), and the projections (35) are axially press fitted into the other. Recesses (36) fitted in an intimate contact manner onto the projections (35) are formed in the other. Thus, a recess/projection fitting structure (M) is formed. In the structure (M), the entire fitting/contact portions (38) of the projections (35) and the recesses (36) are in intimate contact with each other. Further, a shaft come-out prevention structure (M1) is provided between the shaft (12) of the outer joint member and the inner diameter surface of the hub ring (1).

摘要： The invention relates to a wheel hub rotary joint arrangement with an axis of rotation (A), comprising a wheel hub with a wheel flange for connecting a wheel and a sleeve section for receiving a wheel bearing, a constant-velocity rotary joint with an outer joint part (1), an inner joint part and torque-transmitting elements. The outer joint part (1) has a first spur gearing section (2) with first teeth (2a) at the end facing the wheel hub, and the sleeve section has a second spur gearing section with second teeth at the end facing the constant-velocity rotary joint, the two spur gearing sections engaging with one another for torque transmission. Said wheel hub joint arrangement further comprises tensioning means for axially tensioning the wheel hub against the outer joint part, said tensioning means being axially supported on one side on the wheel hub and on the other side on the outer joint part. At least one of the two spur gearing sections is designed such that, viewed in the radial direction, the first and second teeth (2a) initially only contact with one another on a small subsurface of the tooth surfaces facing one another during axial tensioning of the arrangement, and this subsurface increases in size during further tensioning. The spur gearing sections (2) are designed such that, viewed in the radial direction, the first and second teeth (2a) initially contact with one another on the radially inward side during axial tensioning of the arrangement and as tensioning increases also contact with one another on the radially outward side, for which purpose a substructure (1a) of the sleeve section having the teeth (2a) and/or of the outer joint part is designed to be more easily deformable in a radially inward region (R
j ) than in a region (Ra) lying further outward radially.
