Description

本発明は、玉軸受用保持器及び玉軸受に関し、特に、高速回転向けの玉軸受用保持器及び玉軸受に関する。   The present invention relates to a ball bearing cage and a ball bearing, and more particularly to a ball bearing cage and a ball bearing for high-speed rotation.

従来の玉軸受用保持器を備えた玉軸受としては、例えば、図４に示すような玉軸受１００が広く知られている。この玉軸受１００は、外輪１０１と内輪１０２との間に複数の玉１０３が環状の保持器１０４を介して円周方向に転動可能に配設される。保持器１０４は、軸方向に互いに結合される一対の環状部材１０５を備える。一対の環状部材１０５は、例えば、鉄板にプレス加工を施すことによって、凹球面状のポケット形成部１０６ａと平坦状の柱形成部１０７ａとが周方向に略等間隔で交互に形成されている。   As a conventional ball bearing provided with a cage for ball bearings, for example, a ball bearing 100 as shown in FIG. 4 is widely known. In this ball bearing 100, a plurality of balls 103 are arranged between an outer ring 101 and an inner ring 102 so as to roll in the circumferential direction via an annular cage 104. The cage 104 includes a pair of annular members 105 that are coupled to each other in the axial direction. In the pair of annular members 105, for example, a concave spherical pocket forming portion 106a and a flat column forming portion 107a are alternately formed at substantially equal intervals in the circumferential direction by pressing a steel plate.

そして、図５に示すように、一対の環状部材１０５の柱形成部１０７ａ同士をリベット１０８で軸方向に結合することにより、この結合部分に柱部１０７が形成されると共に、ポケット形成部１０６ａ間に玉１０３を転動可能に保持するポケット１０６が形成される。また、従来のその他の玉軸受として、一対の環状部材１０５の柱形成部１０７ａ間にスペーサを介装して隙間を持たせ、潤滑性の向上を図るようにしたものが提案されている。（例えば、特許文献１参照）。   Then, as shown in FIG. 5, the column forming portions 107a of the pair of annular members 105 are connected to each other in the axial direction by the rivets 108, so that the column portions 107 are formed at the connecting portions and between the pocket forming portions 106a. A pocket 106 for holding the ball 103 in a rollable manner is formed. Another conventional ball bearing has been proposed in which a spacer is provided between the column forming portions 107a of the pair of annular members 105 to provide a gap so as to improve lubricity. (For example, refer to Patent Document 1).

ところで、自動車等の回転支持部に多く用いられる転がり軸受は、近年高速化の一途を辿り、ｄｍＮ値（軸受ＰＣＤｄｍと回転速度Ｎとの積）が数十万に達する高速回転用途の転がり軸受も珍しくなく、このような高速回転用途の転がり軸受に上記特許文献１に記載の玉軸受を適用した場合、軸受の取り付け不良や、潤滑不良により各玉の公転速度差が顕著に現れ、保持器に対して大きな回転方向の力が作用する。この際、特許文献１に記載の玉軸受においては、一対の環状部材１０５の柱形成部１０７ａが平坦形状であることから、ポケット形成部１０６ａと柱形成部１０７ａとの間の境部（図１のＡ部）の曲げＲ（曲率半径）が小さいため、この境部に大きな集中応力が作用することで保持器が破損してしまう可能性があり、保持器の耐久性の向上が要望されていた。   By the way, rolling bearings frequently used for rotation support parts of automobiles and the like have been steadily increasing in speed in recent years, and rolling bearings for high-speed rotation applications whose dmN value (product of bearing PCDdm and rotation speed N) reaches several hundred thousand. It is not uncommon, and when the ball bearing described in Patent Document 1 is applied to a rolling bearing for such high-speed rotation applications, the difference in the revolution speed of each ball is noticeable due to poor mounting of the bearing or poor lubrication. On the other hand, a large rotational force acts. At this time, in the ball bearing described in Patent Document 1, since the column forming portion 107a of the pair of annular members 105 has a flat shape, the boundary portion between the pocket forming portion 106a and the column forming portion 107a (FIG. 1). Since the bending R (curvature radius) of part A) is small, there is a possibility that the cage may be damaged due to a large concentrated stress acting on this boundary portion, and improvement of the durability of the cage is desired. It was.

本発明は、このような不都合を解消するためになされたものであり、その目的は、保持器の耐久性を向上することができる玉軸受用保持器及び玉軸受を提供することにある。   The present invention has been made to eliminate such inconveniences, and an object of the present invention is to provide a ball bearing retainer and a ball bearing capable of improving the durability of the retainer.
