Description

本発明は、転がり軸受に関し、特に転がり軸受をハウジング内で軸方向に位置決めするための止め輪を備える転がり軸受に関する。   The present invention relates to a rolling bearing, and more particularly to a rolling bearing provided with a retaining ring for axially positioning the rolling bearing in a housing.

従来より、複写機、プリンター等の事務機器等のハウジング内に装着される転がり軸受を軸方向に位置決めする手段である止め輪を備える止め輪付き転がり軸受が広く使用されている。例えば、日本工業規格のＪＩＳ Ｂ １５０９：２００５により規定される内径寸法を有する止め輪を備える転がり軸受や、ＪＩＳ Ｂ １５１２：２０００により規定される寸法の、止め輪が装着される輪溝を備える転がり軸受がある。以下に、ＪＩＳ規格に従った従来の止め輪付き転がり軸受について図面を参照しつつ説明する。   2. Description of the Related Art Conventionally, a rolling bearing with a retaining ring having a retaining ring, which is a means for positioning a rolling bearing mounted in a housing of an office machine such as a copying machine or a printer in the axial direction, has been widely used. For example, a rolling bearing provided with a retaining ring having an inner diameter defined by JIS B 1509: 2005 of Japanese Industrial Standards, or a rolling bearing provided with a ring groove having a dimension defined by JIS B 1512: 2000. There are bearings. Hereinafter, a conventional rolling bearing with a retaining ring according to the JIS standard will be described with reference to the drawings.

図３は、従来の止め輪付き転がり軸受に用いる外輪及び止め輪を示し、（ａ）は外輪の側面図であり、（ｂ）は、（ａ）の線ＩＩＩＢ−ＩＩＩＢに沿った外輪の断面図であり、（ｃ）は、止め輪の正面図である。図４は、図３の外輪に止め輪を装着した状態の図３（ａ）に対応する断面図である。   3A and 3B show an outer ring and a retaining ring used in a conventional rolling bearing with a retaining ring, wherein FIG. 3A is a side view of the outer ring, and FIG. 3B is a sectional view of the outer ring along line IIIB-IIIB in FIG. It is a figure and (c) is a front view of a retaining ring. FIG. 4 is a cross-sectional view corresponding to FIG. 3A in a state in which a retaining ring is attached to the outer ring of FIG.

従来の止め輪付き転がり軸受は、環状の外輪１０３と、外輪１０３と同心で、外輪の半径方向内方に配置された環状の内輪（不図示）と、外輪１０３と内輪との間に形成される環状空間に配置される複数の転動体（不図示）と、外輪１０３と内輪との間で複数の転動体を転動可能に、周方向で等間隔に保持する環状の保持部材（不図示）と、を備える（例えば、特許文献１参照。）。   A conventional rolling bearing with a retaining ring is formed between an annular outer ring 103, an annular inner ring (not shown) concentric with the outer ring 103 and disposed radially inward of the outer ring, and the outer ring 103 and the inner ring. A plurality of rolling elements (not shown) disposed in the annular space, and an annular holding member (not shown) that holds the plurality of rolling elements between the outer ring 103 and the inner ring at equal intervals in the circumferential direction. (See, for example, Patent Document 1).

図３（ａ）に示されるように、環状の外輪１０３の外周面には、その周方向において断面が矩形状の凹部すなわち輪溝１０５が刻設されている。なお、図中においてｄ１とは、輪溝の深さを示す。また、図３（ｂ）に示されるように、輪溝１０５の径をＤ１とする。   As shown in FIG. 3 (a), a recess having a rectangular cross section in the circumferential direction, that is, a ring groove 105 is formed on the outer peripheral surface of the annular outer ring 103. In the figure, d1 indicates the depth of the ring groove. Further, as shown in FIG. 3B, the diameter of the annular groove 105 is D1.

図３（ｃ）に示されるように、止め輪１０７は、切り欠き１１３を有するＣ型形状である。止め輪の内径をＤ３とする。ここで、止め輪１０３と輪溝１０５とは、Ｄ３＜Ｄ１を満たすように寸法付けされている。   As shown in FIG. 3C, the retaining ring 107 has a C shape having a notch 113. The inner diameter of the retaining ring is D3. Here, the retaining ring 103 and the ring groove 105 are dimensioned to satisfy D3 <D1.

図中において、破線は、止め輪１０７を外輪１０３に装着した状態（図４参照。）、すなわち止め輪１０７が拡開した状態を示している。切り欠き１１３を画成する切り欠き部１０７ａは、元の形から装着された状態へは、距離ｘ変位する。また、切り欠き部１０７ａから時計方向に９０°ずれた止め輪の側部１０７ｂは、元の形から距離ｙだけ変位する。さらに、切り欠き部１０７ａに対して、直径方向に対向する基部１０７ｃでは、拡開前後において、変位はほぼ０である。   In the drawing, a broken line indicates a state where the retaining ring 107 is attached to the outer ring 103 (see FIG. 4), that is, a state where the retaining ring 107 is expanded. The notch 107a that defines the notch 113 is displaced by a distance x from the original shape to the attached state. Further, the retaining ring side portion 107b shifted 90 ° clockwise from the notch portion 107a is displaced from the original shape by a distance y. Furthermore, the displacement of the base 107c that faces the notch 107a in the diametrical direction is substantially zero before and after the expansion.

このことから、図４に示された止め輪１０７が輪溝１０５内に嵌合、すなわちタイトフィットした状態では、基部１０７ｃから切り欠き部１０７ａに進みに従い、止め輪の復元力による押圧力が大きくなり、切り欠き部１０７ａが当接する外輪１０３の部分に最も大きな押圧力が掛かる。
特開平９−１４２７６（段落〔０００２〕〔０００３〕、図５、６） Therefore, when the retaining ring 107 shown in FIG. 4 is fitted in the ring groove 105, that is, in a tight fit state, the pressing force due to the restoring force of the retaining ring increases as it proceeds from the base 107c to the notch 107a. Thus, the largest pressing force is applied to the portion of the outer ring 103 with which the notch 107a abuts.
JP-A-9-14276 (paragraphs [0002] [0003], FIGS. 5 and 6)

従来の転がり軸受において、輪溝１０５に装着され拡開した止め輪１０７には、原形に戻ろうとする復元力が生じ、その復元力による止め輪１０７からの押圧力が外輪１０３に加わる。押圧力は、外輪１０３の外周に対して均一ではなく、基部１０７ｃから切り欠き部１０７ａに近づくに従い大きくなる。従って、止め輪の装着後に外輪の破損、外輪の真円度が悪化、偏荷重による作動不良、転がり軸受の作動時に異音の発生、偏磨耗による寿命の低下という問題が生じる。特に、近年、装置のコンパクト化に伴い、転がり軸受の薄肉化が進んでいるため、上記問題はより深刻になる可能性がある。   In the conventional rolling bearing, the retaining ring 107 mounted and expanded in the ring groove 105 generates a restoring force to return to the original shape, and the pressing force from the retaining ring 107 by the restoring force is applied to the outer ring 103. The pressing force is not uniform with respect to the outer periphery of the outer ring 103, and increases as it approaches the notch 107a from the base 107c. Accordingly, there are problems that the outer ring is damaged after the retaining ring is mounted, the roundness of the outer ring is deteriorated, the operation failure is caused by the uneven load, the noise is generated when the rolling bearing is operated, and the life is shortened by the uneven wear. In particular, in recent years, with the downsizing of devices, rolling bearings have become thinner, so the above problem may become more serious.

一つの解決策としては、止め輪が装着された外輪の真円度を維持するため、止め輪の切り欠き部から加わる押圧力に抗する程度の剛性を持つ外輪とすることが考えられる。しかし、転がり軸受の小型化に伴う転がり軸受の薄肉化の観点から実用的ではない。   As one solution, in order to maintain the roundness of the outer ring on which the retaining ring is mounted, it is conceivable to use an outer ring having rigidity enough to resist the pressing force applied from the notch portion of the retaining ring. However, it is not practical from the viewpoint of reducing the thickness of the rolling bearing accompanying the downsizing of the rolling bearing.

そこで、止め輪による転がり軸受の軸方向についての位置決め機能を確実に行いつつ、転がり軸受の小型化に伴う外輪の薄肉化に対応できる止め輪付き転がり軸受を提供することを目的とする。   Therefore, an object of the present invention is to provide a rolling bearing with a retaining ring that can cope with the thinning of the outer ring accompanying the downsizing of the rolling bearing while reliably performing the positioning function in the axial direction of the rolling bearing by the retaining ring.

上記課題を解決するための本発明の転がり軸受の第１の態様は、内輪と、前記内輪の半径方向外方に配置され、前記内輪に対して相対回転可能な外輪と、前記内輪と前記外輪により画成される環状空間内に配置される転動体と、前記外輪の外周面で周方向に延在する輪溝に配置される円弧状の止め輪と、を備える転がり軸受けであって、前記止め輪の内径をＤ３と、前記輪溝の径をＤ１とし、前記輪溝の深さをｄ１とすると、Ｄ１≦Ｄ３＜Ｄ１＋ｄ１の関係を満たす。   A first aspect of a rolling bearing according to the present invention for solving the above-described problems includes an inner ring, an outer ring disposed radially outward of the inner ring and capable of rotating relative to the inner ring, the inner ring and the outer ring. A rolling bearing comprising: a rolling element disposed in an annular space defined by: an arc-shaped retaining ring disposed in a ring groove extending in a circumferential direction on an outer peripheral surface of the outer ring, When the inner diameter of the retaining ring is D3, the diameter of the ring groove is D1, and the depth of the ring groove is d1, the relationship of D1 ≦ D3 <D1 + d1 is satisfied.

本発明によれば、止め輪の内径は、外輪の輪溝の径と同じであるか、大きくなるように寸法付けされているので、輪溝に装着された状態の止め輪には復元力が生じず、止め輪から押圧力が外輪に加わることがなく外輪の真円度を維持できる。また、止め輪の内径は、輪溝の深さに輪溝の径を加えた寸法より小さく寸法付けされているので、止め輪と外輪の輪溝との間で係合する部分、すなわち係り代が存在し、転がり軸受の位置決め機能を確実に果たすことができる。   According to the present invention, since the inner diameter of the retaining ring is the same as or larger than the diameter of the annular groove of the outer ring, the retaining ring mounted in the annular groove has a restoring force. The circularity of the outer ring can be maintained without any pressing force being applied to the outer ring from the retaining ring. The inner diameter of the retaining ring is smaller than the dimension obtained by adding the diameter of the annular groove to the depth of the annular groove, so that the portion engaged between the retaining ring and the annular groove of the outer ring, that is, the engagement allowance. Therefore, it is possible to reliably perform the positioning function of the rolling bearing.

以下、本発明の転がり軸受の実施形態について図面を参照しつつ説明する。各図面中、同一要素は同一符号で示してある。   Hereinafter, embodiments of the rolling bearing of the present invention will be described with reference to the drawings. In the drawings, the same elements are denoted by the same reference numerals.

本実施形態は、本発明の止め輪付き転がり軸受を、転動体が球状部材である玉軸受に適用した例である。図１は、本発明の転がり軸受の実施形態の縦方向断面図である。図２（ａ）、（ｂ）は、図１の線ＩＩ−ＩＩに沿った断面図である。なお、図２は、図面の明確化の観点から外輪及び止め輪のみを示した。   This embodiment is an example in which the rolling bearing with a retaining ring of the present invention is applied to a ball bearing whose rolling element is a spherical member. FIG. 1 is a longitudinal sectional view of an embodiment of a rolling bearing of the present invention. 2A and 2B are cross-sectional views taken along line II-II in FIG. FIG. 2 shows only the outer ring and the retaining ring from the viewpoint of clarifying the drawing.

転がり軸受１は、環状の外輪３と、外輪３の半径方向内方で、外輪３と同心に配置された環状の内輪９と、外輪３と内輪９との間に形成される環状空間に配置される複数の球状部材１１と、外輪３と内輪９との間で複数の球状部材１１を転動可能に、周方向で等間隔に保持する環状の保持部材（不図示）と、を備える。   The rolling bearing 1 is disposed in an annular outer ring 3, an annular inner ring 9 disposed concentrically with the outer ring 3 on the radially inner side of the outer ring 3, and an annular space formed between the outer ring 3 and the inner ring 9. And a plurality of spherical members 11 and an annular holding member (not shown) that holds the plurality of spherical members 11 between the outer ring 3 and the inner ring 9 at equal intervals in the circumferential direction.

さらに、外輪３の外周面には、半径方向断面が矩形状で、周方向に延在する凹部、すなわち輪溝５が刻設されている。輪溝５には、Ｃ型形状（円弧状）の止め輪７が装着されている。   Furthermore, the outer ring 3 has a rectangular cross section in the radial direction and a recess extending in the circumferential direction, that is, a ring groove 5. The ring groove 5 is fitted with a C-shaped (arc-shaped) retaining ring 7.

上記転がり軸受１はハウジング１３内の所定位置に配置され、止め輪７により、転がり軸受１の軸方向（図１の左右方向）に関する位置決めが行われる。上記構成において、止め輪付き転がり軸受１の外輪３と内輪５とは、互いに相対回転可能である。   The rolling bearing 1 is arranged at a predetermined position in the housing 13, and the retaining ring 7 positions the rolling bearing 1 in the axial direction (left and right direction in FIG. 1). In the above configuration, the outer ring 3 and the inner ring 5 of the rolling bearing 1 with a retaining ring can rotate relative to each other.

次に、転がり軸受１の各構成要素の寸法関係について説明する。
外輪３に設けられた輪溝５の径の寸法をＤ３、止め輪７の内径の寸法をＤ１とすると、止め輪７の内径Ｄ１の寸法が輪溝５の径Ｄ３の寸法と同じであるか、Ｄ３より大きい寸法関係である。
Ｄ３≦Ｄ１・・・（１） Next, the dimensional relationship of each component of the rolling bearing 1 will be described.
If the dimension of the diameter of the ring groove 5 provided in the outer ring 3 is D3 and the dimension of the inner diameter of the retaining ring 7 is D1, is the dimension of the inner diameter D1 of the retaining ring 7 equal to the dimension of the diameter D3 of the annular groove 5? , A dimensional relationship larger than D3.
D3 ≦ D1 (1)

すなわち、止め輪７は、輪溝５の底面５ａを締め付けることのない、いわゆるルーズフィットで輪溝５に装着されている。具体的に、止め輪の内径Ｄ３が輪溝５の径Ｄ１より大きい場合が図２に示されており、図２（ａ）に示すように外輪３と止め輪７とが同心となった状態では、輪溝５の底面５ａに止め輪７は接触しない寸法関係である。よって、輪溝５の底面５ａと止め輪７の内周との間に隙間Ｓが存在する。従って、止め輪７が輪溝５に装着された状態では、止め輪７に復元力が生じておらず、止め輪からの押圧力が外輪３に加わることはない。   That is, the retaining ring 7 is attached to the annular groove 5 by a so-called loose fit that does not tighten the bottom surface 5a of the annular groove 5. Specifically, FIG. 2 shows a case where the inner diameter D3 of the retaining ring is larger than the diameter D1 of the annular groove 5, and the outer ring 3 and the retaining ring 7 are concentric as shown in FIG. 2 (a). Then, the dimensional relationship is such that the retaining ring 7 does not come into contact with the bottom surface 5 a of the ring groove 5. Therefore, a gap S exists between the bottom surface 5 a of the ring groove 5 and the inner periphery of the retaining ring 7. Therefore, in a state where the retaining ring 7 is mounted in the ring groove 5, no restoring force is generated in the retaining ring 7, and no pressing force from the retaining ring is applied to the outer ring 3.

更に、装着された止め輪７は、輪溝５内に保持され、転がり軸受の軸方向の位置決め機能を発揮できるように寸法付けする必要がある。
そこで、止め輪７の内径Ｄ１は、輪溝５の径Ｄ３に輪溝５の深さｄ１を加えた寸法より短くなるような寸法関係とすることにより、輪溝５の側壁５ｂと、止め輪７とが係合する係り代Ｅを設ける（図２（ｂ）参照。）。すなわち、
Ｄ１＜Ｄ３＋ｄ１・・・（２）の関係を満たす場合である。
この場合には、輪溝５内に装着された止め輪７は、輪溝５の側壁５ａと係合する係り代Ｅを有し、転がり軸受が軸方向に移動することを防止できる。 Furthermore, the attached retaining ring 7 is held in the ring groove 5 and needs to be dimensioned so as to exhibit the axial positioning function of the rolling bearing.
Therefore, the inner diameter D1 of the retaining ring 7 has a dimensional relationship that is shorter than the dimension obtained by adding the depth d1 of the annular groove 5 to the diameter D3 of the annular groove 5, so that the sidewall 5b of the annular groove 5 and the retaining ring 7 is provided (see FIG. 2B). That is,
This is a case where the relationship of D1 <D3 + d1 (2) is satisfied.
In this case, the retaining ring 7 mounted in the ring groove 5 has the engagement allowance E that engages with the side wall 5a of the ring groove 5 and can prevent the rolling bearing from moving in the axial direction.

図２（ｂ）に示すように、止め輪７の切り欠き部７ａから周方向時計回りに２７０°の角度位置の部分７ｃが、輪溝５の底面５ａに当接した状態（隙間Ｓが０）では、切り欠き部７ａから周方向時計回りに９０°の角度位置の部分７ｂの部分は、輪溝５の底面５ａから最も離れた位置に配置される。この場合であっても、輪溝５の側壁５ｂに止め輪７の側部７ｂとが係合する係り代Ｅが存在する。このように、止め輪７の周方向全域に亘り輪溝５の側面５ｂとの係り代Ｅを確保することにより、止め輪７の位置決め機能が確保される。   As shown in FIG. 2 (b), the portion 7c at an angular position of 270 ° in the clockwise direction from the notch 7a of the retaining ring 7 is in contact with the bottom surface 5a of the ring groove 5 (the gap S is 0). ), The portion 7b having an angular position of 90 ° in the clockwise direction from the notch 7a is disposed at a position farthest from the bottom surface 5a of the ring groove 5. Even in this case, there is a tapping E where the side portion 7b of the retaining ring 7 is engaged with the side wall 5b of the ring groove 5. Thus, by securing the engagement allowance E with the side surface 5b of the ring groove 5 over the entire circumferential direction of the retaining ring 7, the positioning function of the retaining ring 7 is ensured.

上記の式（１）、（２）をまとめ、Ｄ３≦Ｄ１＜Ｄ３＋ｄ１・・・（３）の寸法関係を満たす外輪と止め輪を備える止め輪付き転がり軸受であれば本発明の所期の目的が達成できる。すなわち、止め輪付き転がり軸受の構成要素が式（３）の寸法関係を満たすと、止め輪７による押圧力が外輪に付与されることなく、また、止め輪と輪溝の側壁との間に係り代が存在し、転がり軸受の位置決め機能を発揮できる。
また、上記寸法関係を有する転がり軸受は、特に以下に示す薄肉転がり軸受に適用すると、より効果的である。 Summarizing the above formulas (1) and (2), D3 ≦ D1 <D3 + d1 (3) A rolling bearing with a retaining ring having an outer ring and a retaining ring satisfying the dimensional relationship of (3) is intended. Can be achieved. That is, when the components of the rolling bearing with a retaining ring satisfy the dimensional relationship of the formula (3), the pressing force by the retaining ring 7 is not applied to the outer ring and between the retaining ring and the side wall of the ring groove. There is an engagement allowance, and the positioning function of the rolling bearing can be exhibited.
Moreover, the rolling bearing having the above dimensional relationship is more effective when applied to the thin rolling bearing shown below.

上記実施形態では、転動体として球を利用した転がり軸受の構成について説明したが、本発明はこれに限定されることはない。例えば、円筒ころ軸受や針状ころ軸受といった、外輪と、外輪に対して相対回転可能な内輪とを備える転がり軸受であれば、本発明の止め輪付き転がり軸受を適用できる。   In the above embodiment, the configuration of the rolling bearing using a ball as a rolling element has been described, but the present invention is not limited to this. For example, the rolling bearing with a retaining ring of the present invention can be applied to any rolling bearing including an outer ring and an inner ring that can rotate relative to the outer ring, such as a cylindrical roller bearing or a needle roller bearing.

また、実施形態では、止め輪を外輪の外周面に設けた構成としたが、内輪の内周面や、軸の外周面に止め輪を装着し、転がり軸受の軸方向の位置決めを行う構成の止め輪付き転がり軸受であっても本発明を適用できることは言うまでもない。   In the embodiment, the retaining ring is provided on the outer peripheral surface of the outer ring. However, the retaining ring is attached to the inner peripheral surface of the inner ring or the outer peripheral surface of the shaft, and the axial direction of the rolling bearing is configured. Needless to say, the present invention can be applied to a rolling bearing with a retaining ring.

この発明は、その本質的特性から逸脱することなく数多くの形式のものとして具体化することができる。よって、上述した実施形態は専ら説明上のものであり、本発明を制限するものではないことは言うまでもない。   The present invention can be embodied in many forms without departing from its essential characteristics. Therefore, it is needless to say that the above-described embodiment is exclusively for description and does not limit the present invention.
