摘要： A wheel-supporting roller-bearing unit with air compressor that is compact and capable of keeping resistance against the rotation of the hub 4c low while at the same time maintaining good balance, and when necessary, is capable of obtaining compressed air having sufficient pressure regardless of the traveling speed of the vehicle. A plurality of cylinder holes 53 are located at a plurality of locations that are evenly spaced around the circumferential direction on the inside of a cylinder block 50 that is connected and fastened to the inside end section in the axial direction of the hub 4c. Pistons 54 fit inside these cylinder holes 53 and are moved back and forth by a piston-drive mechanism 62 as the cylinder block 50 rotates. The air compressor 2c is a reciprocating-piston compressor, so it is possible to obtain the required air pressure regardless of rpm. Also, by placing a plurality of cylinder holes 53 and pistons 54 at uniform intervals around in the circumferential direction, it is possible to suppress the resistance against the rotation of the hub 4c.

摘要： After a hub supporting member is mounted on an end portion of a spindle, correction work is applied to a ring-shaped supporting surface which is an end face of the hub supporting member, whereby perpendicularity of the supporting surface relative to a rotational center axis of the spindle is improved. Thereafter, while the hub main body is made to rotate together with the spindle in such a state that the mounting surface abuts with the supporting surface, grinding finishing work is applied to a cylindrical surface portion (a portion on which inner rings are fitted) of the hub main body. As a result, the perpendicularity of the mounting surface relative to the geometric center axis of the cylindrical surface portion is improved.

摘要： It is possible to obtain best performance in a structure in which moment rigidity can be improved by setting a pitch circle diameter of an outboard row to be larger than a pitch circle diameter of an inboard row.Thermally-hardened layers 16a, 16b are formed, at two locations along an axial direction, in portions of an inner circumferential surface of an outer ring 3 including outer ring raceways 12a, 12b. The thermally-hardened layers 16a, 16b are separated from each other by an unhardened portion 17 in an axially middle portion of the outer ring 3. A non-cylindrical curved portion 18 having an arcuate generatrix is provided on the axially middle portion of the inner circumferential surface of the outer ring 3, between the outer ring raceways 12a, 12b. A thickness Ta of the thermally-hardened layer 16a in the portion including the outer ring raceway 12a on an axially outer side is larger than a thickness Tb of the thermally-hardened layer 16b in the portion including the outer ring raceway 12b on the axially inner side.
