Bearing apparatus and producing method thereof |
摘要 |
A bearing apparatus comprises a hollow shaft (14) provided around its outer peripheral surface with a bearing fitting region, and a rolling bearing having an inner ring (15) fitted around the bearing fitting region of the hollow shaft. A shaft end of the hollow shaft (14) is bent outwardly in a diametrical direction, thereby being caulkd on an outer end surface of the inner ring of the rolling bearing. The bearing fitting region has a hardened layer (24) in its region from an inner end surface corresponding position of the inner ring of the rolling bearing to a portion before an outer end surface corresponding position, and has a non-hardened layer in its region from the outer end surface corresponding position of the inner ring to the shaft end of the hollow shaft. A position of a caulkd side end portion of the hardened layer (24b) is defined based on a predetermined relational expression. <IMAGE> |
