Description

【０００１】
【発明の属する技術分野】
本発明はアンギュラ玉軸受に係り、特に、外輪を加熱して内外輪の軌道面間に玉を組み込む非分離型アンギュラ玉軸受に関する。
【０００２】
【従来の技術】
アンギュラ玉軸受とは、転動体として玉を用いたアンギュラコンタクトラジアル軸受である。このようなアンギュラ玉軸受は、内輪または外輪の少なくとも一方において、起動面に隣接する溝肩の軸方向一方側を落し、カウンタボアを形成して構成されている（例えば、特許文献１を参照）。そして、このようなカウンタボアの最小半径と玉の配列の外接円の半径との差（外輪にカウンタボアを設ける場合）、あるいはカウンタボアの最大半径と玉の配列の内接円の半径との差（内輪にカウンタボアを設ける場合）をかかり代または締め代と称する。すなわち、例えば外輪にカウンタボアを設けた場合には、カウンタボアの最大径と軌道面の最大径との差がかかり代となる。
【０００３】
アンギュラ玉軸受において、かかり代が小さいと、軸受の組立は容易となるが、その反面外輪または内輪が外れやすくなってしまう。一方、かかり代が大きいと、軸受の組立が難しくなり、さらに組立時に玉傷が発生してしまう場合があるから、かかり代の設定は重要である。
【０００４】
従来、外輪の軸方向一方側に、かかり代を設けないカウンタボアを有し、外輪を容易に着脱可能な外輪分離型のアンギュラ玉軸受において、内輪側カウンタボアのかかり代をＷ、玉の直径をＤｗとしたときに、０．０３≦Ｗ／Ｄｗ≦０．１０とすることが提案されている（例えば、特許文献２を参照）。

【発明が解決しようとする課題】
内輪外周面の軌道面を挟んだ軸方向両側に肩部が形成され、かつ外輪内周面の軌道面の軸方向一方側に肩部が形成され、他方側にかかり代を有するカウンタボアが形成されてなるいわゆる非分離型アンギュラ玉軸受においても、軸受の組立が容易かつ外輪が脱落しにくいかかり代を設定することが要望されている。このような非分離型アンギュラ玉軸受は、外輪を例えば１００℃程度に加熱し、熱膨張させた状態で軸受の組立を行うが、この場合上述した従来技術のようなかかり代の設定では、かかり代が過大となって軸受の組立が困難となり、玉傷が発生するおそれもある。
上述した問題に鑑み、本発明の課題は、非分離型アンギュラ玉軸受の組立を容易化しかつ外輪の脱落を防止することにある。
【０００７】
【課題を解決する手段】
本発明は、外周面に軌道面が形成されてなる内輪と、内周部に軌道面が形成されてなる外輪と、内輪の軌道面と外輪の軌道面との間に組み込まれた複数の玉と、玉を保持する保持器とを有して構成され、内輪には軌道面を挟んだ軸方向両側に肩部が形成され、外輪には軌道面に対して軸方向一方側に肩部が形成されかつ他方側にカウンタボアが形成され、複数の玉の配列の外接円の半径とカウンタボアの最小径との差であるかかり代をＷ、玉の直径をＤｗとしたときに、
０．００５ ≦ Ｗ／Ｄｗ ≦ ０．０３０
を満たすことを特徴とする非分離型アンギュラ玉軸受によって上述した課題を解決する。
【０００８】
本発明によれば、非分離型アンギュラ玉軸受における外輪のカウンタボアのかかり代を適切化することができる。これによって、軸受の組立が容易となって玉傷の発生を防止することができ、また、外輪が脱落しにくくなる効果がある。すなわち、Ｗ／Ｄｗを０．００５未満とすると、外輪の脱落が生じやすくなるから、これを０．００５以上に設定する。一方、Ｗ／Ｄｗを０．０３０超に設定すると、軸受の組立が困難となり、組立時に玉傷が発生しやすくなるので、これを０．０３０以下に設定する。
【０００９】
【発明の実施の形態】
以下、本発明を適用してなる非分離型アンギュラ玉軸受の一実施形態について説明する。図１は、本実施形態の非分離型アンギュラ玉軸受を径方向に切って見た状態を示す断面図である。図１に示すように、軸受１は、外周部に軌道面が形成されてなる内輪３と、内輪３と略軸心を揃えて配列され、内周部に軌道面が形成されてなる外輪５とを有する。そして、内輪３の軌道面と外輪５の軌道面との間には、周方向に略等間隔に分布して、転動体の玉である複数の鋼球７が組み込まれている。そして、複数の鋼球７を周方向に所定の間隔で保持するための保持器９が設けられている。
【００１０】
図１に示すように、内輪３は、略矩形の断面形状を有して形成され、その外周面の軸方向中央部に、周方向にわたって延在する溝状の軌道面１１が形成されている。軌道面１１の溝断面形状は、鋼球７の径を考慮して定められた曲率の円弧状となっている。そして、内輪３の軌道面を挟んだ軸方向両側の領域には、軌道面１１の両端部と径が略等しい円筒面上の肩部１３、１５が形成されている。
【００１１】
一方、外輪５には、その内周面の軸方向中央部に、周方向にわたって延在する溝状の軌道面１７が形成されている。そして、外輪５の内周面のうち軌道面１７に対して一方側の領域には、軌道面１７の内径が最小となる部分の径（最小径）と略内径が等しい円筒内面状の肩部１９が形成されている。そして、外輪５の軌道面１７の、肩部１９と反対の側には、肩部１９に対して内径を大きく形成されたカウンタボア２１が形成されている。このカウンタボア２１は、軌道面の縁部に隣接し、軸方向にわたって略一定の内径を有する平行部２３と、この平行部２３の軌道面１７と反対側の端部から、外輪５の端面にかけて徐々に径を拡大して形成されたテーパ部２５とを有して構成されている。
【００１２】
そして、本実施形態においては、軸受１の周方向に分布して配置された複数の鋼球７の配列の外接円の半径と、カウンタボア２１のうち最も内径が小さい平行部２３の内径（半径）との差であるかかり代をＷとし、鋼球７の直径をＤｗとしたときに、以下の式１を満たすようなＷおよびＤｗを設定したことを特徴とする。
０．００５ ≦ Ｗ／Ｄｗ ≦ ０．０３０ （式１）
【００１３】
次に、本実施形態の軸受１を組み立てる方法について説明する。図２は、軸受１の組立時の状態を示す断面図である。図２（ａ）は、内輪３に鋼球７および保持器９が装着され、外輪５は未だ分離している状態を示している。また、図２（ｂ）は、内輪３、鋼球７および保持器９を外輪５と組み付けるときの状態を示している。軸受１の組立にあたっては、先ず外輪５を、例えば１００℃程度の高温に加熱して、熱膨張させる。そして、図示しない下側に位置する鋼球７を、外輪５の図示しない下側の軌道面１７上に設置し、図２に示すように、径方向反対側つまり図２（ｂ）において上方に図示される鋼球７、保持器９および内輪３を、下側の鋼球７の中心を軸として回動させ、カウンタボア２１側から外輪５内の所定の位置に挿入する。
【００１４】
そして、このときに、図２（ｂ）に示すように、鋼球７の表面と、外輪５の内周部の平行部２３とが接触する場合があるが、上述したようにかかり代Ｗと鋼球７の直径Ｄｗとを設定することにより、組み込みは容易であり、鋼球７の表面にいわゆる玉傷はつきにくい。そして、軸受１は、図１に示すような状態に組み込まれるが、このとき外輪５は常温まで温度が下げられ、この状態においては、外輪５は、脱落しにくくなっている。
【００１５】
以上のように、本実施形態によれば、外輪５のカウンタボア２１のかかり代Ｗと、鋼球７の直径Ｄｗとの関係が、０．００５≦Ｗ／Ｄｗ≦０．０３０となるように設定しているから、軸受の組立が容易となって玉傷が発生しにくくなり、また、組立後に外輪が脱落しにくくなる効果がある。
【００１６】
なお、本発明は、上述した実施形態に限定されるものではなく、本発明の範囲内で適宜変更を加えることが可能である。例えば、内輪、外輪の形状や構成も任意に変更を加えることが可能である。また、保持器の形状ないしは構成や、シールやシールド等の密封板の有無についても任意に変更可能である。

BACKGROUND OF THE INVENTION
The present invention relates to an angular ball bearing, and more particularly, to a non-separable angular ball bearing in which an outer ring is heated to incorporate balls between raceways of inner and outer rings.
[0002]
[Prior art]
An angular contact ball bearing is an angular contact radial bearing using balls as rolling elements. Such an angular ball bearing is configured such that at least one of the inner ring and the outer ring has a counter bore formed by dropping one axial direction side of the groove shoulder adjacent to the starting surface (see, for example, Patent Document 1). . The difference between the minimum radius of the counterbore and the radius of the circumscribed circle of the ball array (when the counterbore is provided on the outer ring), or the maximum radius of the counterbore and the radius of the inscribed circle of the ball array The difference (when a counter bore is provided on the inner ring) is referred to as the allowance or tightening allowance. That is, for example, when a counterbore is provided on the outer ring, a difference between the maximum diameter of the counterbore and the maximum diameter of the raceway surface is incurred.
[0003]
In an angular contact ball bearing, if the engagement margin is small, the assembly of the bearing becomes easy, but on the other hand, the outer ring or inner ring tends to come off. On the other hand, if the cost is large, it is difficult to assemble the bearing, and ball damage may occur at the time of assembly. Therefore, the setting of the cost is important.
[0004]
Conventionally, the outer ring has a counter bore on one side in the axial direction, and the outer ring can be easily attached and detached. It is proposed that 0.03 ≦ W / Dw ≦ 0.10 when D is Dw (see, for example, Patent Document 2).

[Patent Document 2]
Japanese Patent Laid-Open No. 11-270563 (first page, FIG. 1 etc.)
[0006]
[Problems to be solved by the invention]
Shoulder portions are formed on both sides in the axial direction across the raceway surface of the inner ring outer peripheral surface, a shoulder portion is formed on one side in the axial direction of the raceway surface of the outer ring inner peripheral surface, and a counter bore having a margin is formed on the other side Even in the so-called non-separable angular contact ball bearings that are formed, it is desired to set an allowance that allows easy assembly of the bearings and that prevents the outer ring from falling off. Such non-separable angular contact ball bearings are assembled in a state where the outer ring is heated to, for example, about 100 ° C. and thermally expanded. The allowance is excessive, making it difficult to assemble the bearing and possibly causing ball damage.
In view of the above-described problems, an object of the present invention is to facilitate the assembly of a non-separable angular contact ball bearing and to prevent the outer ring from falling off.
[0007]
[Means for solving the problems]
The present invention provides an inner ring having a raceway surface formed on an outer peripheral surface, an outer ring having a raceway surface formed on an inner peripheral portion, and a plurality of balls incorporated between the raceway surface of the inner ring and the raceway surface of the outer ring. And a retainer for holding a ball, the inner ring has shoulders on both sides in the axial direction across the raceway surface, and the outer ring has a shoulder on one side in the axial direction with respect to the raceway surface. And the counterbore is formed on the other side, and the difference between the radius of the circumscribed circle of the array of balls and the minimum diameter of the counterbore is W, and the ball diameter is Dw,
0.005 ≦ W / Dw ≦ 0.030
The above-mentioned problems are solved by a non-separable angular contact ball bearing characterized by satisfying
[0008]
According to the present invention, it is possible to make appropriate the allowance of the counter bore of the outer ring in the non-separable angular contact ball bearing. As a result, the assembly of the bearing is facilitated, and the occurrence of ball scratches can be prevented, and the outer ring is less likely to drop off. In other words, if the W / Dw is less than 0.005, the outer ring is likely to drop out, so this is set to 0.005 or more. On the other hand, if W / Dw is set to be more than 0.030, it is difficult to assemble the bearing, and ball damage is likely to occur during the assembly, so this is set to 0.030 or less.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a non-separable angular contact ball bearing to which the present invention is applied will be described. FIG. 1 is a cross-sectional view showing a state in which the non-separable angular contact ball bearing of this embodiment is viewed in the radial direction. As shown in FIG. 1, the bearing 1 includes an inner ring 3 having a raceway surface formed on an outer peripheral portion, and an outer ring 5 formed by aligning the inner ring 3 and a substantially axial center and having a raceway surface formed on an inner peripheral portion. And have. A plurality of steel balls 7 which are balls of rolling elements are incorporated between the raceway surface of the inner ring 3 and the raceway surface of the outer ring 5 so as to be distributed at substantially equal intervals in the circumferential direction. And the holder | retainer 9 for hold | maintaining the several steel ball 7 in the circumferential direction at predetermined intervals is provided.
[0010]
As shown in FIG. 1, the inner ring 3 is formed to have a substantially rectangular cross-sectional shape, and a groove-like raceway surface 11 extending in the circumferential direction is formed at the axially central portion of the outer peripheral surface. . The groove cross-sectional shape of the raceway surface 11 has an arc shape with a curvature determined in consideration of the diameter of the steel ball 7. Further, shoulder portions 13 and 15 on a cylindrical surface having substantially the same diameter as both end portions of the raceway surface 11 are formed in regions on both sides in the axial direction across the raceway surface of the inner ring 3.
[0011]
On the other hand, the outer ring 5 is formed with a groove-like raceway surface 17 extending in the circumferential direction at the central portion in the axial direction of the inner circumferential surface. Then, in a region on one side of the inner circumferential surface of the outer ring 5 with respect to the raceway surface 17, a shoulder portion having a cylindrical inner surface whose diameter is the same as the diameter (minimum diameter) of the portion where the inner diameter of the raceway surface 17 is the smallest. 19 is formed. A counter bore 21 having a larger inner diameter than the shoulder 19 is formed on the side of the raceway surface 17 of the outer ring 5 opposite to the shoulder 19. The counter bore 21 is adjacent to the edge of the raceway surface, has a parallel portion 23 having a substantially constant inner diameter in the axial direction, and the end of the parallel portion 23 opposite to the raceway surface 17 from the end surface of the outer ring 5. The taper portion 25 is formed by gradually increasing the diameter.
[0012]
In the present embodiment, the radius of the circumscribed circle of the array of the plurality of steel balls 7 arranged distributed in the circumferential direction of the bearing 1 and the inner diameter (radius) of the parallel portion 23 having the smallest inner diameter among the counter bores 21. W and Dw are set so as to satisfy the following formula 1, where W is the cost of the difference between the steel ball 7 and Dw.
0.005 ≦ W / Dw ≦ 0.030 (Formula 1)
[0013]
Next, a method for assembling the bearing 1 of the present embodiment will be described. FIG. 2 is a cross-sectional view showing a state when the bearing 1 is assembled. FIG. 2A shows a state in which the steel ball 7 and the cage 9 are attached to the inner ring 3 and the outer ring 5 is still separated. FIG. 2B shows a state when the inner ring 3, the steel ball 7 and the cage 9 are assembled with the outer ring 5. In assembling the bearing 1, first, the outer ring 5 is heated to a high temperature of, for example, about 100 ° C. to be thermally expanded. Then, a steel ball 7 located on the lower side (not shown) is placed on a lower raceway surface 17 (not shown) of the outer ring 5, and as shown in FIG. The illustrated steel ball 7, cage 9 and inner ring 3 are rotated about the center of the lower steel ball 7 as an axis and inserted into a predetermined position in the outer ring 5 from the counter bore 21 side.
[0014]
At this time, as shown in FIG. 2B, the surface of the steel ball 7 and the parallel part 23 of the inner peripheral part of the outer ring 5 may come into contact with each other. By setting the diameter Dw of the steel ball 7, it is easy to incorporate, and the surface of the steel ball 7 is less likely to be damaged. The bearing 1 is incorporated in a state as shown in FIG. 1, and at this time, the temperature of the outer ring 5 is lowered to room temperature, and in this state, the outer ring 5 is difficult to drop off.
[0015]
As described above, according to the present embodiment, the relationship between the allowance W of the counter bore 21 of the outer ring 5 and the diameter Dw of the steel ball 7 is 0.005 ≦ W / Dw ≦ 0.030. Since it is set, there is an effect that the assembly of the bearing becomes easy and ball damage is less likely to occur, and the outer ring is less likely to drop off after assembly.
[0016]
In addition, this invention is not limited to embodiment mentioned above, A change can be suitably added within the scope of the present invention. For example, the shapes and configurations of the inner ring and the outer ring can be arbitrarily changed. Further, the shape or configuration of the cage and the presence or absence of a sealing plate such as a seal or a shield can be arbitrarily changed.
[0017]
【The invention's effect】
According to the present invention, the assembly of the non-separable angular ball bearing can be facilitated and the outer ring can be prevented from falling off.
