Description

本発明は、合成樹脂製の保持器を備えた外輪分離形のアンギュラ玉軸受に関する。   The present invention relates to an outer ring separated angular contact ball bearing provided with a cage made of synthetic resin.

アンギュラ玉軸受は、内外輪が非分離となっているものが一般的であるが、例えば減速機用で内外輪を締まり嵌めとする場合等、使用条件によっては、内輪、ボールおよび保持器からなる部分組立品を軸に圧入し、外輪をハウジングに圧入する構成の外輪分離形のものが用いられることがある。このような外輪分離形のアンギュラ玉軸受では、保持器が内周側からボールをポケットに自在に収脱できる構造であるため、部分組立品を外輪と分離した状態で取り扱うときに保持器が内輪から外れると、ボールが保持器の内周側から脱落してしまう。そこで、この部分組立品の分解を防止するために、内輪のカウンタボア部の外径を、内輪と分離した状態にある保持器に保持されたボールの配列の内接円径よりも大きくして、組立後の保持器が内輪から外れにくいようにしている。従って、軸受を組み立てる際には、内輪と分離状態でボールを保持した保持器を、そのボールが内輪のカウンタ部を乗り越えるように弾性変形させて内輪に組み付けている。   Angular contact ball bearings generally have non-separated inner and outer rings. For example, when the inner and outer rings are an interference fit for a reduction gear, the inner and outer rings are composed of an inner ring, a ball, and a cage. A separate outer ring type structure in which a subassembly is press-fitted into a shaft and an outer ring is press-fitted into a housing may be used. In such an outer ring-separated angular ball bearing, the cage has a structure in which the ball can be freely retracted into and removed from the inner circumferential side. Therefore, when the subassembly is handled in a state separated from the outer ring, the cage is If it comes off, the ball falls off from the inner peripheral side of the cage. Therefore, in order to prevent disassembly of this subassembly, the outer diameter of the counter bore portion of the inner ring is made larger than the inscribed circle diameter of the ball array held in the cage separated from the inner ring. The assembled cage is made difficult to come off from the inner ring. Therefore, when assembling the bearing, the cage that holds the ball in a state separated from the inner ring is elastically deformed so that the ball gets over the counter part of the inner ring and is assembled to the inner ring.

ところで、上記外輪分離形のアンギュラ玉軸受の保持器としてナイロン等の合成樹脂製のものを用いた場合には、保持器が弾性変形しやすいため、保持器の内輪への組み付けは容易に行える。しかし、外輪と分離した状態の部分組立品をその軸方向が垂直方向を向く姿勢にすると、保持器がボールの自重によって撓んでボールとともに内輪から外れ、部分組立品が分解してしまうことがある。このため、軸受の組立時や機械への組込時には、部分組立品の取り扱いに十分注意する必要があり、作業効率が悪い。   By the way, when a cage made of synthetic resin such as nylon is used as the cage of the outer ring separated angular ball bearing, the cage is easily elastically deformed, so that the cage can be easily assembled to the inner ring. However, if the sub-assembly separated from the outer ring is in a posture in which the axial direction is vertical, the cage may be bent by its own weight and come off from the inner ring together with the ball, and the sub-assembly may be disassembled. . For this reason, when assembling the bearing or assembling it into a machine, it is necessary to pay careful attention to the handling of the sub-assembly, and work efficiency is poor.

一方、保持器を弾性変形しにくい鋼板製のものとすれば、部分組立品の分解は生じにくくなるが、保持器が内輪への組み付けの際に塑性変形し、組付後の保持器のかしめが必要になって軸受の組立性が低下する場合が多くなる。そこで、本出願人は、内輪のカウンタボア部の外径と、内輪と分離状態の保持器に保持されたボール配列の内接円径との寸法差を、ボール径の３〜１０％とすることにより、部分組立品の分解を防止しつつ、保持器が内輪への組付時に塑性変形を生じないようにしたアンギュラ玉軸受を提案した（特許文献１参照。）。
特開平１１−２７０５６３号公報 On the other hand, if the cage is made of a steel plate that is not easily elastically deformed, disassembly of the subassembly is less likely to occur, but the cage is plastically deformed when assembled to the inner ring, and the cage is caulked after assembly. Is required and the assembly of the bearing is often reduced. Therefore, the present applicant sets the dimensional difference between the outer diameter of the counter bore portion of the inner ring and the inscribed circle diameter of the ball array held in the cage separated from the inner ring to 3 to 10% of the ball diameter. Thus, an angular ball bearing in which the cage is prevented from being plastically deformed when assembled to the inner ring while preventing the partial assembly from being disassembled has been proposed (see Patent Document 1).
Japanese Patent Laid-Open No. 11-270563

しかしながら、上記特許文献１に記載のアンギュラ玉軸受は、鋼板製の保持器を使用しているため、保持器を内輪への組み付けの際に弾性変形させるのにかなり大きい力を加える必要があり、組立性の面では樹脂製の保持器を使用したものに及ばない。また、保持器の製造コストが樹脂製のものよりも高くなってしまう。   However, since the angular ball bearing described in Patent Document 1 uses a cage made of steel plate, it is necessary to apply a considerably large force to elastically deform the cage when assembled to the inner ring. In terms of ease of assembly, it is not as good as that using a resin cage. Moreover, the manufacturing cost of a cage | basket will become higher than the thing made from resin.

本発明の課題は、合成樹脂製の保持器を使用した外輪分離形のアンギュラ玉軸受において、内輪、ボールおよび保持器からなる部分組立品が組立後に分解しないようにすることである。   An object of the present invention is to prevent a subassembly including an inner ring, a ball and a cage from being disassembled after assembling in an angular contact ball bearing with a separated outer ring using a cage made of synthetic resin.

上記の課題を解決するため、本発明は、内輪のカウンタボア部の外径を、内輪と分離した状態にある合成樹脂製の保持器のポケットに保持器の内周側から収脱自在に保持されたボールの配列の内接円径よりも大きくし、軸受組立時には、前記ボールを保持した保持器を、そのボールが前記内輪のカウンタボア部を乗り越えるように弾性変形させて内輪に組み付けるようにし、前記内輪、ボールおよび保持器からなる部分組立品をその軸方向が垂直方向を向く姿勢で組み込んだ外輪分離形のアンギュラ玉軸受において、前記内輪のカウンタボア部の外径と前記ボール配列の内接円径との寸法差をボール径の５〜２０％とする構成を採用した。
In order to solve the above-described problems, the present invention holds the outer diameter of the counter bore portion of the inner ring in a pocket of a synthetic resin cage that is separated from the inner ring so as to be detachable from the inner peripheral side of the cage. When the bearings are assembled, the cage holding the balls is elastically deformed so that the balls get over the counterbore part of the inner ring and assembled to the inner ring. In the outer ring separated angular contact ball bearing in which the sub-assembly including the inner ring, the ball and the cage is assembled in a posture in which the axial direction is vertical , the outer diameter of the counter bore portion of the inner ring and the inner diameter of the ball array A configuration was adopted in which the dimensional difference from the contact circle diameter was 5 to 20% of the ball diameter.

すなわち、内輪のカウンタボア部の外径と、内輪と分離状態の保持器に保持されたボール配列の内接円径との寸法差を、ボール径の５％以上とすることにより、保持器が組立後にボールの自重程度の力を受けて撓んでも内輪から外れないようにしたのである。そして、その上限をボール径の２０％とすることにより、保持器の内輪への組み付けやすさが損なわれないようにした。   That is, by making the dimensional difference between the outer diameter of the counter bore portion of the inner ring and the inscribed circle diameter of the ball arrangement held in the cage separated from the inner ring 5% or more of the ball diameter, Even after the assembly, the ball was bent under the force of its own weight so that it would not come off the inner ring. Then, by setting the upper limit to 20% of the ball diameter, the ease of assembling the cage to the inner ring is not impaired.

本発明の外輪分離形のアンギュラ玉軸受は、上述したように、合成樹脂製の保持器を使用し、内輪のカウンタボア部の外径と、内輪と分離状態の保持器に保持されたボール配列の内接円径との寸法差をボール径の５〜２０％としたものであるから、保持器の内輪への組み付けが容易に行え、鋼板製保持器を使用したものよりも組立性に優れるうえ、組立後に保持器が内輪から外れて部分組立品が分解するおそれも少ない。従って、組立時や機械への組込時には、取り扱いやすく、効率良く作業できる。また、コスト面でも、鋼板製保持器を使用した場合よりも安価に製造できる。   As described above, the outer ring separated angular contact ball bearing of the present invention uses a synthetic resin cage, the outer diameter of the counter bore portion of the inner ring, and the ball array held by the cage separated from the inner ring Since the dimensional difference from the inscribed circle diameter is 5 to 20% of the ball diameter, the cage can be easily assembled to the inner ring, and the assembly is superior to those using a steel plate cage. In addition, there is little risk that the cage is detached from the inner ring after assembly and the subassembly is disassembled. Therefore, when assembling or assembling into a machine, it is easy to handle and can work efficiently. In terms of cost, it can be manufactured at a lower cost than when a steel plate cage is used.

以下、図面に基づき、本発明の実施形態を説明する。この実施形態のアンギュラ玉軸受は、外輪分離形のもので、図１に示すように、内輪１と、外輪２と、内外輪１、２間に転動自在に配される複数のボール３と、これらのボール３を保持する保持器４とからなる。保持器４は、合成樹脂製で、内周側からボール３を自在に収脱できる円形のポケット４ａが円周方向に等間隔で形成されている。また、内輪１および外輪２は、それぞれカウンタボア部１ａ、２ａを有しており、そのうちの外輪２のカウンタボア部２ａの内径が軌道溝２ｂの溝底の内径以上の大きさに形成され、外輪２が内輪１、ボール３および保持器４からなる部分組立品５と分離するようになっている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The angular ball bearing of this embodiment is of an outer ring separation type, and as shown in FIG. 1, an inner ring 1, an outer ring 2, and a plurality of balls 3 that are freely rollable between the inner and outer rings 1 and 2. And a holder 4 for holding these balls 3. The cage 4 is made of synthetic resin, and circular pockets 4a are formed at regular intervals in the circumferential direction so that the balls 3 can be freely removed from the inner circumference side. The inner ring 1 and the outer ring 2 have counter bore portions 1a and 2a, respectively, and the inner diameter of the counter bore portion 2a of the outer ring 2 is formed larger than the inner diameter of the groove bottom of the raceway groove 2b. The outer ring 2 is separated from the subassembly 5 composed of the inner ring 1, the ball 3 and the cage 4.

一方、図２に示すように、内輪１のカウンタボア部１ａの外径Ａは、内輪１と分離した状態にある保持器４に保持されたボール３の配列の内接円径Ｂよりも大きく形成されており、その寸法差（Ａ−Ｂ）はボール３の直径ｄの５〜２０％に設定されている。従って、軸受を組み立てる際には、ボール３を保持した保持器４を、そのボール３が内輪１のカウンタボア部１ａを乗り越えるように弾性変形させて内輪１に組み付けることにより、内輪１とボール３と保持器４とを部分組立品５として一体化している。   On the other hand, as shown in FIG. 2, the outer diameter A of the counter bore portion 1 a of the inner ring 1 is larger than the inscribed circle diameter B of the array of balls 3 held by the cage 4 in a state separated from the inner ring 1. The dimensional difference (AB) is set to 5 to 20% of the diameter d of the ball 3. Therefore, when assembling the bearing, the retainer 4 holding the ball 3 is elastically deformed so that the ball 3 gets over the counter bore portion 1a of the inner ring 1 and is assembled to the inner ring 1, whereby the inner ring 1 and the ball 3 are assembled. And the retainer 4 are integrated as a subassembly 5.

このアンギュラ玉軸受は、上記の構成であり、内輪１のカウンタボア部１ａの外径Ａと、内輪１と分離状態の保持器４に保持されたボール３配列の内接円径Ｂとの寸法差（Ａ−Ｂ）を、ボール径ｄの５〜２０％としたので、保持器４の内輪１への組み付けが容易なうえ、組立後に部分組立品５をその軸方向が垂直方向を向く姿勢にしても、保持器４がボール３の自重で内輪１から外れて部分組立品５が分解することがない。   This angular ball bearing has the above-described configuration, and the dimensions of the outer diameter A of the counter bore portion 1a of the inner ring 1 and the inscribed circle diameter B of the array of balls 3 held in the cage 4 separated from the inner ring 1 are as follows. Since the difference (AB) is 5 to 20% of the ball diameter d, it is easy to assemble the retainer 4 to the inner ring 1 and, after assembly, the sub-assembly 5 is oriented so that its axial direction is vertical. Even so, the cage 4 is not detached from the inner ring 1 by the weight of the ball 3 and the subassembly 5 is not disassembled.

次に、本発明の効果を確認するために実施した評価試験について説明する。試験は、内輪のカウンタボア部の外径Ａを変えることにより、ボール配列の内接円径Ｂとの寸法差（Ａ−Ｂ）をボール径ｄの０〜３０％の範囲で変化させ、組立性（保持器の内輪への組み付けやすさ）および取扱性（組立後の部分組立品の分解しにくさ）を評価した。その試験条件および評価結果をまとめて表１に示す。   Next, an evaluation test conducted for confirming the effect of the present invention will be described. In the test, by changing the outer diameter A of the counter bore portion of the inner ring, the dimensional difference (A−B) from the inscribed circle diameter B of the ball array is changed in the range of 0 to 30% of the ball diameter d, and the assembly is performed. (Ease of assembling the cage to the inner ring) and handleability (hardness to disassemble the subassembly after assembly) were evaluated. The test conditions and evaluation results are summarized in Table 1.

Figure 0004824457

表１からわかるように、内輪のカウンタボア部の外径Ａとボール３配列の内接円径Ｂとの寸法差（Ａ−Ｂ）を、ボール径ｄの４％以下にすると、組立後に保持器が内輪から外れて部分組立品が分解しやすくなり、ボール径ｄの２５％以上にすると、保持器の内輪への組み付けが困難になることが確認された。   As can be seen from Table 1, if the dimensional difference (AB) between the outer diameter A of the counter bore portion of the inner ring and the inscribed circle diameter B of the ball 3 array is 4% or less of the ball diameter d, it is retained after assembly. It has been confirmed that when the cage is detached from the inner ring and the subassembly is easily disassembled and the ball diameter is 25% or more of the ball diameter d, it is difficult to assemble the cage to the inner ring.
