[Means for solving problems]
Of the wheel bearing unit and the manufacturing method thereof of the present invention, the wheel bearing unit according to claims 1 and 3 has a stationary side track on a stationary side peripheral surface, similarly to the conventional wheel bearing unit described above. A stationary wheel having a surface and being supported and fixed to a suspension device in a used state, a rotating wheel having a rotating side raceway surface whose surface is heat-treated and cured on the rotating side peripheral surface, and the rotating side raceway surface and the stationary side. A plurality of rolling elements provided between the raceway surface and a mounting flange provided on the outer peripheral surface of the rotating wheel and connecting and fixing the braking rotating body and the wheel to the side surface thereof in a used state are provided.

特に、本発明のうちの請求項1に記載した車輪用軸受ユニットに於いては、これら制動用回転体及び車輪を結合固定する為の取付フランジの側面は、上記回転側軌道面を熱処理した後に所定の形状に加工されたものである。又、上記回転側軌道面は、上記取付フランジの側面を所定の形状に加工した後に、この側面を基準として所定の形状及び寸法に加工されたものである。
又、請求項3に記載した車輪用軸受ユニットに於いては、上記制動用回転体及び車輪を結合固定する為の取付フランジの外側面は、所定の形状に加工されてからこの取付フランジの円周方向複数個所に形成された取付孔にスタッドのセレーション部を、これら各取付孔の内側からこの取付孔に圧入した後、再度加工されている。
In particular, in the wheel bearing unit according to claim 1 of the present invention, the side surface of the mounting flange for connecting and fixing the braking rotating body and the wheel is after heat treatment of the rotating side raceway surface. It is processed into a predetermined shape. Further, the rotation side raceway surface is formed by processing the side surface of the mounting flange into a predetermined shape and then processing the side surface into a predetermined shape and dimensions with reference to this side surface.
Further, in the wheel bearing unit according to claim 3, the outer surface of the mounting flange for connecting and fixing the braking rotating body and the wheel is processed into a predetermined shape and then the circle of the mounting flange. The serrations of the studs are press-fitted into the mounting holes formed at a plurality of locations in the circumferential direction from the inside of each of the mounting holes, and then processed again.

又、請求項2に記載した車輪用軸受ユニットの製造方法は、上記回転輪のうちで回転側軌道面部分を熱処理硬化させた後、取付フランジの側面を所定の形状に加工する。次いで、上記回転側軌道面を、この側面を基準面として利用する事により、所定の形状及び寸法に加工する。
更に、請求項5に記載した車輪用軸受ユニットの製造方法は、制動用回転体及び車輪を結合固定する為の取付フランジの外側面を所定の形状に加工してから、この取付フランジの円周方向複数個所に形成された取付孔にスタッドのセレーション部を、これら各取付孔の内側からこの取付孔に圧入した後、再度加工する。
Further, in the method for manufacturing a wheel bearing unit according to claim 2, the side surface of the mounting flange is processed into a predetermined shape after the rotating side raceway surface portion of the rotating wheel is heat-treated and cured. Next, the rotation side raceway surface is processed into a predetermined shape and dimensions by using this side surface as a reference surface.
Further, in the method for manufacturing a wheel bearing unit according to claim 5, the outer surface of the mounting flange for connecting and fixing the braking rotating body and the wheel is processed into a predetermined shape, and then the circumference of the mounting flange is formed. The serrations of the studs are press-fitted into the mounting holes formed at a plurality of directions from the inside of each of the mounting holes, and then processed again.

本例の場合、上記取付フランジ13の外側面27(図1〜2の左側面)を、上記ホイール1及びロータ2を取り付けるべき取付面としている。従って、上記外側面27の形状精度が悪化する事を極力防止する必要がある。これに対して、上記スタッド24のセレーション部26を上記取付孔23に圧入すると、上記取付フランジ13がこの取付孔23の近傍部分で多少なりとも変形する。この変形が、上記取付フランジ13の外側面27にまで及び、この外側面27が凸方向に変形すると、この外側面27に対し結合固定した、上記ロータ2の振れが大きくなりがちになる。そこで、上記取付孔23と上記セレーション部26との嵌合部を、極力内方に寄せて設ける事により、上記変形に基づき上記外側面27が凸方向に変形する事がない様にしている。勿論、上記セレーション部26の幅W26は、十分な嵌合強度を確保できる範囲で、上記取付フランジ13の厚さT13よりも十分に小さく(W26≪T13)している。図示の例では、上記取付孔23の端部で、上記外側面27側開口部に、座ぐり加工或は旋削加工等により、面取り状の大径部を形成しているので、上記セレーション部26の圧入に基づく、上記外側面27の凸方向への変形を、より確実に防止できる。更には、上記セレーション部26の圧入後、上記外側面27の加工を再度行なえば、この外側面27の歪みを確実になくせる。 In the case of this example, the outer surface 27 (left side surface of FIGS. 1 and 2) of the mounting flange 13 is the mounting surface on which the wheel 1 and the rotor 2 should be mounted. Therefore, it is necessary to prevent the shape accuracy of the outer surface 27 from deteriorating as much as possible. On the other hand, when the serration portion 26 of the stud 24 is press-fitted into the mounting hole 23, the mounting flange 13 is deformed to some extent in the vicinity of the mounting hole 23. When this deformation extends to the outer surface 27 of the mounting flange 13 and the outer surface 27 is deformed in the convex direction, the runout of the rotor 2 coupled and fixed to the outer surface 27 tends to increase. Therefore, by providing the fitting portion between the mounting hole 23 and the serration portion 26 as close to the inside as possible, the outer surface 27 is not deformed in the convex direction based on the deformation. Of course, the width W 26 of the serration portion 26 is sufficiently smaller than the thickness T 13 of the mounting flange 13 (W 26 << T 13 ) within a range in which sufficient fitting strength can be secured. In the illustrated example, at the end of the mounting hole 23, a chamfered large-diameter portion is formed in the opening on the outer surface 27 side by counterbore processing, turning processing, or the like. It is possible to more reliably prevent the deformation of the outer surface 27 in the convex direction based on the press-fitting of the outer surface 27. Further, if the outer surface 27 is processed again after the serration portion 26 is press-fitted, the distortion of the outer surface 27 can be surely eliminated.
