摘要： A method is directed to a production of a bearing device for a wheel including an inner member (1) and an outer member (2) rotatable relative to each other through a plurality of rolling elements (3), in which a component part forming one of the inner member (1) and the outer member (2) is a hot forged product. In the practice of this method, during or at the end of a hot forging step for hot forging the component part, a portion of the component part is cooled by spraying a coolant or by controlling an atmospheric temperature, to thereby render a matrix of the component part to represent a standard structure and render a surface portion of the component part to represent a non-standard structure (30).

摘要： An inner ring (23) is fitted on the bush (10) with a buttress (23a) which abuts against the rotating component of the coupling. An outer ring (21) has an inwardly directed flange (21a) and a number of balls are arranged between the inner and outer rings. A ball bearing (20) with a cage (25) holds the balls peripherally spaced apart. A Belleville spring (30) engages with the end (31) of its internal diameter in the securing wall surface (14c) of a stop section (14), formed on the outer peripheral surface of the bush (10). The securing wall surface of the stop section of the bush has a shape which prevents the end of the internal diameter of the Belleville spring from slipping radially outwards.

摘要： Provided is a preload inspection method for a wheel bearing device enabling more accurate checking of preload. The invention comprises: a press-fitting step S02 for press-fitting an inner ring 4 to a small-diameter stepped part 3a; a first bearing preload value calculation step S03 for calculating a first bearing preload value P1 on the basis of a first axial direction negative clearance G1; a first rotating torque measurement step S05 for measuring a first rotating torque Ta after the press-fitting step; a swaging step S06 for swaging the small-diameter stepped part to the inner ring after the first rotating torque measurement step; a second bearing preload value calculation step S07 for calculating a second bearing preload value P2 on the basis of a second axial direction negative clearance G2; a second rotating torque measurement step S08 for measuring a second rotating torque Tb after the swaging step; a third bearing preload value calculation step S09 for calculating a third bearing preload value P3 by adding, to the first bearing preload value, a preload change amount ?P based on a differential torque ?T between the first rotating torque and the second rotating torque; and a determination step S10 for determining the suitability of the preload from the second bearing preload value and the third bearing preload value.

摘要： A bearing device for a wheel enabling the easy control of quality since there is no possibility of cracking even if caulking is applied thereto. The bearing device comprises an outer ring (3) having double rows of raceway surfaces on the inner periphery thereof, an inner member having raceway surfaces opposed to the raceway surfaces, and balls (1) interposed between the double rows of raceway surfaces opposed to each other. The inner member further comprises a HUB ring (4) and an inner ring (2). Caulking is applied to the HUB ring (4) to join it to the inner ring (2). The grain size number of the austenite grains of a caulked section (4b) is at least 6.

摘要： PROBLEM TO BE SOLVED: To attain reduction of a cost, compactness and high speediness. SOLUTION: A ball bearing 3 is arranged between a periphery 1a of a resin- made sleeve 1 and an end face 2a of a side plate 2, to be elastically held by a belleville spring 4. A diameter ϕT of a contact part of a flange part 3a1 in an inner ring 3a in contact with a rotary member of a clutch device and a pitch circle diameter PCD have a relation where ϕT>PCD.

摘要： PROBLEM TO BE SOLVED: To increase the inner diameter of a conical spring for improving the incorporation of the conical spring and to prevent its removal from an engaging wall surface by forming the engaging wall surface of the stopper part of a sleeve to have a shape for regulating the removal of the inner diameter end of the engaged conical spring to an outer diameter side. SOLUTION: For assembling a clutch release bearing device A, the assembly of a ball bearing 20 and a conical spring 30 is fitted around the outer periphery of a sleeve 10 from one end side, the conical spring 30 is pressed by using a conical spring incorporating jig, and the inner diameter end 31 of the conical spring 30 is advanced to a stopper part 40. When the ball bearing 20 is moved to be aligned, a force for moving the conical spring 30 in a radial direction is applied. However, since the engaging wall surface 14c of the stopper part 14 is a sharp slope against the axis of the sleeve 10, the conical spring 30 is held in the engaging wall surface 14c while the removal of its inner diameter end 31 is prevented. By using the comical spring 30 having a large inner diameter, the incorporation of the conical spring 30 is improved.
