Title:
WHEEL BEARING DEVICE, AND METHOD OF CONTROLLING BEARING CLEARANCE GAP
Document Type and Number:
Japanese Patent JP3930675
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To observe a hearing axial clearance gap brought into direct correlation with a pre-load amount to be controlled, not grasping the pre-load amount indirectly via torque or the like, to provide a wheel bearing device in which a proper pre-load is secured.
SOLUTION: Press-in is stopped once in a midway of a press-in process at first to measure an initial bearing axial clearance gap δ0 and an assembling width T0 between an axle 20 and an inner bearing ring 30 or an outer joint member 50. Then, the press-in is continued to measure an assembling width T1 under a condition where the press-in is finished, so as to find the bearing clearance gap δ1=δ0-(T0-T1). Caulking is carried out thereafter to measure an assembling width T2 after the caulking. The bearing axial clearance gap (pre-load amount) δ2 in a final assembly after caulking is found according to an equation δ2=δ1+(T1-T2).
