ところで、図１２と図１３に示すような車輪用転がり軸受装置においては、外輪部材１２０の車内側の外輪軌道面１２２に対する複数の転動体１３３と、これら転動体１３３を保持する車内側の保持器１３５とを組み付ける場合、図１３に示すように、車内側の保持器１３５の各ポケットに転動体１３３をそれぞれ嵌込んで組み付けたものを、外輪部材１２０の嵌込筒部１２６の内孔を通して外輪部材１２０の車内側の外輪軌道面１２２上まで挿入することによって組み付けられる。
このため、外輪部材１２０の嵌込筒部１２６の内径寸法をＡ’とし、転動体１３３（１３２）の外接円径寸法（外輪軌道面の最大径寸法に相当する）をＢ’としたときに、Ａ’≧Ｂ’の関係に設定する必要がある。
一方、高剛性化を図る（軸受性能を向上させる）ためには、転動体１３３（１３２）の外接円径寸法をＢ’を大きくし、これに対応して転動体１３３（１３２）の配設個数を多くしたり、あるいは、転動体１３３（１３２）の直径寸法を大きくすることで対処することが考えられる。
しかしながら、外輪部材１２０の嵌込筒部１２６の外径寸法Ｆ’は、車体側部材１０１の取付孔１０４に対応しなければならず、嵌込筒部１２６の外径寸法Ｆ’を変更することができない。ひいては、外輪部材１２０の嵌込筒部１２６の肉厚を確保して内径寸法Ａ’を大きくすることができない。
この結果、図１２に示すような車輪用転がり軸受装置においては、転動体１３２（１３２）の外接円径寸法をＢ’を嵌込筒部１２６の内径寸法Ａ’よりも大きくして高剛性化を図ることが困難である。 Meanwhile, the wheel rolling bearing device shown in FIGS. 12 and 13, a plurality of rolling elements 133 against the interior side of the outer ring raceway surface 122 of the outer ring member 120, the interior side that holds these rolling elements 133 coercive When the holder 135 is assembled, as shown in FIG. 13, the rolling body 133 is fitted into each pocket of the cage 135 inside the vehicle , and the inner hole of the fitting cylindrical portion 126 of the outer ring member 120 is assembled. The outer ring member 120 is assembled by being inserted up to the outer ring raceway surface 122 inside the vehicle.
For this reason, when the inner diameter dimension of the fitting cylindrical portion 126 of the outer ring member 120 is A ′ and the circumscribed circle diameter dimension of the rolling element 133 (132) (corresponding to the maximum diameter dimension of the outer ring raceway surface) is B ′. , A ′ ≧ B ′ must be set.
On the other hand, in order to achieve high rigidity (improve bearing performance), the circumscribed circle diameter of the rolling element 133 (132) is increased to B ′, and the rolling element 133 (132) is disposed correspondingly. It is conceivable to cope with the problem by increasing the number or increasing the diameter of the rolling element 133 (132).
However, the outer diameter dimension F ′ of the fitting cylinder part 126 of the outer ring member 120 must correspond to the mounting hole 104 of the vehicle body side member 101, and the outer diameter dimension F ′ of the fitting cylinder part 126 is changed. I can't. As a result, it is not possible to secure the thickness of the fitting tube portion 126 of the outer ring member 120 and increase the inner diameter dimension A ′.
As a result, in the rolling bearing device for a wheel as shown in FIG. 12, the circumscribed circle diameter dimension of the rolling element 132 (132) is made larger than the inner diameter dimension A ′ of the fitting cylinder portion 126 to increase the rigidity. It is difficult to plan.

この発明の目的は、前記問題点に鑑み、外輪部材の嵌込筒部の外径寸法及び内径寸法を変えることなく、転動体の外接円径寸法を大きく設定することができ高剛性化を図ることができる車輪用転がり軸受装置の製造方法を提供することである。 In view of the above problems, an object of the present invention is to increase the rigidity by increasing the circumscribed circle diameter of the rolling element without changing the outer diameter and inner diameter of the fitting cylinder portion of the outer ring member. it is to provide a method of manufacturing a rolling bearing equipment capable.
