Description

本発明は、クリープ防止転がり軸受に関するものである。より詳細には、例えばオルタネータやカーエアコン用コンプレッサ等、自動車用の各種補機の回転支持部に組み込むことにより、効果的にクリープを防止することの可能な転がり軸受に関するものである。   The present invention relates to an anti-creep rolling bearing. More specifically, the present invention relates to a rolling bearing capable of effectively preventing creep by being incorporated in a rotation support portion of various auxiliary equipment for automobiles such as an alternator and a car air conditioner compressor.

一般に、自動車用各種補機はハウジングの内側に、回転軸を支承する為の転がり軸受を組み込む場合が多い。組み込み状態では、この転がり軸受を構成する外輪を上記ハウジングの内側に、締まり嵌めにより内嵌固定する。   In general, various auxiliary machines for automobiles often incorporate a rolling bearing for supporting a rotating shaft inside a housing. In the assembled state, the outer ring constituting the rolling bearing is fitted and fixed inside the housing by an interference fit.

ところで、ハウジングの材料として広く用いられるアルミニウム合金の熱膨張率は、転がり軸受の外輪を構成する軸受鋼の熱膨張率よりも大きい。この為、アルミニウム合金製のハウジングに転がり軸受を内環固定した場合、温度上昇時に上記ハウジングに対する外輪の締め代が低下、もしくは喪失し、ハウジングの内側で外輪が回転する、所謂クリープが発生すると共に、転がり軸受による回転支持部にがたつきが発生する場合がある。しかも、クリープが発生した場合、上記外輪の回転に伴ってハウジングの内周面が摩耗して上記がたつきが次第に大きくなる傾向がある。   By the way, the thermal expansion coefficient of the aluminum alloy widely used as the material of the housing is larger than the thermal expansion coefficient of the bearing steel constituting the outer ring of the rolling bearing. For this reason, when the rolling bearing is fixed to the inner ring housing in the aluminum alloy housing, when the temperature rises, the allowance of the outer ring relative to the housing is reduced or lost, and so-called creep occurs in which the outer ring rotates inside the housing. In addition, rattling may occur in the rotation support portion due to the rolling bearing. In addition, when creep occurs, the inner peripheral surface of the housing wears with the rotation of the outer ring, and the rattling tends to gradually increase.

このようなクリープを防止する技術として、例えば図３に示すようなクリープ防止転がり軸受１が知られている。クリープ防止転がり軸受１は、回転輪である内輪２と、固定輪である外輪３と、これら内外輪２，３間に転動自在に設けられた複数の転動体４と、転動体４を保持する保持器５とを備えている。   As a technique for preventing such creep, for example, a creep preventing rolling bearing 1 as shown in FIG. 3 is known. The anti-creep rolling bearing 1 holds an inner ring 2 that is a rotating ring, an outer ring 3 that is a fixed ring, a plurality of rolling elements 4 that are rotatably provided between the inner and outer rings 2 and 3, and the rolling element 4. The cage 5 is provided.

また、回転軸８を上記内輪２に一体回転可能に嵌合するとともに、外輪３をアルミニウム合金製のハウジング９に設けられた嵌合部内周面９ａに嵌合することにより、回転軸８を回転自在に支承している。   Further, the rotary shaft 8 is fitted to the inner ring 2 so as to be integrally rotatable, and the outer ring 3 is fitted to a fitting portion inner peripheral surface 9a provided in an aluminum alloy housing 9, whereby the rotary shaft 8 is rotated. Supports freely.

外輪３の外周面には、軸方向中心に関して対称的に周溝７，７が設けられており、周溝７，７の中にアルミニウム合金製のハウジングよりも熱膨張係数の大きい合成樹脂製のクリープ防止部材６，６が配されている。   Circumferential grooves 7 and 7 are provided on the outer peripheral surface of the outer ring 3 symmetrically with respect to the axial center, and the peripheral grooves 7 and 7 are made of a synthetic resin having a larger thermal expansion coefficient than the aluminum alloy housing. Anti-creep members 6 and 6 are arranged.

上記クリープ防止部材６，６は外輪３の周溝７，７とハウジング９の嵌合部内周面９ａとの間に介在するよう配置されており、これらのクリープ防止部材６，６が周囲温度の変化に応じて膨張または収縮することにより、ハウジング９に対する外輪３の締め代を確保し、所定のクリープトルクを発生して外輪３のハウジング９に対する取り付け状態を維持するようになっている。   The creep prevention members 6 and 6 are disposed so as to be interposed between the circumferential grooves 7 and 7 of the outer ring 3 and the fitting portion inner peripheral surface 9a of the housing 9, and these creep prevention members 6 and 6 are at an ambient temperature. By expanding or contracting in accordance with the change, the allowance of the outer ring 3 with respect to the housing 9 is ensured, and a predetermined creep torque is generated to maintain the mounting state of the outer ring 3 with respect to the housing 9.

この様なクリープ防止転がり軸受は、例えば特許文献１に記載された技術のように、クリープ防止部材を樹脂バンドで形成して周溝に嵌め合わせて構成するものや、例えば特許文献２に記載された技術のように、周溝にリング状のクリープ防止部材を射出成形（例えば、インサート成形）により構成するものが知られている。   Such a creep-preventing rolling bearing is configured by forming a creep-preventing member with a resin band and fitting it into a circumferential groove, for example, as in the technique described in Patent Document 1, or for example, Patent Document 2 As in the prior art, a ring-shaped creep preventing member is formed in the circumferential groove by injection molding (for example, insert molding).

特開平０９−３１４６９５号公報JP 09-314695 A 特開２００３−２８７０４３号公報JP 2003-287043 A

しかしながら、これらの先行技術には、軸受外輪に外輪周溝を付ける加工が必要である。また、合成樹脂バンドを介する場合には、組付け部品が一つ増える事から、組付け工程の増加及び組付け違いの危険性が大きくなるという問題点がある。   However, these prior arts require a process for attaching an outer ring circumferential groove to the bearing outer ring. In addition, when the synthetic resin band is used, there is a problem that the number of assembling parts is increased by one, so that the number of assembling steps and the risk of misassembly are increased.

さらに、これらのクリープ防止玉軸受では、クリープ防止のために機能する面積はクリープ防止部材の大きさに左右される事から、使用条件が過酷化する現在のオルタネータ等の自動車用の各種補機では、クリープ防止性能が不足する問題がある。   Further, in these anti-creep ball bearings, the area that functions to prevent creep depends on the size of the anti-creep member, so in various auxiliary equipment for automobiles such as current alternators where the usage conditions become severe, There is a problem of insufficient creep prevention performance.

そこで、本発明は、組付け工程での作業増加が無く、且つ安価で、先行技術以上のクリープ防止性能を有するクリープ防止転がり軸受を提供することを目的とする。   Accordingly, an object of the present invention is to provide an anti-creep rolling bearing that does not increase the work in the assembly process, is inexpensive, and has an anti-creep performance higher than that of the prior art.

上記の目的を達成するため、本発明に係るクリープ防止転がり軸受は、内周面に外輪軌道を有する外輪と、外周面に内輪軌道を有する内輪と、前記外輪軌道と内輪軌道との間に転動自在に設けられた複数の転動体と、前記転動体を保持する保持器とクリープ防止部材を備えたクリープ防止転がり軸受において、前記クリープ防止部材は合成樹脂製であり、且つ、前記外輪の外周面と一体に成型されており、さらに、少なくとも前記外輪の幅と同等以上の軸方向幅を有することを特徴とする。   In order to achieve the above object, a creep-preventing rolling bearing according to the present invention comprises an outer ring having an outer ring raceway on an inner peripheral surface, an inner ring having an inner ring raceway on an outer peripheral surface, and between the outer ring raceway and the inner ring raceway. In the anti-creep rolling bearing provided with a plurality of freely provided rolling elements, a cage for holding the rolling elements and an anti-creep member, the anti-creep member is made of a synthetic resin, and the outer periphery of the outer ring It is molded integrally with the surface, and further has an axial width at least equal to or greater than the width of the outer ring.

本発明によれば、従来のクリープ防止転がり軸受のように、クリープ防止部材を格納する溝部を設置する必要がないので、加工コストを抑える事が出来る。   According to the present invention, unlike the conventional anti-creep rolling bearing, it is not necessary to install a groove portion for storing the anti-creep member, so that the processing cost can be reduced.

また、樹脂バンド製の従来のクリープ防止転がり軸受に比べ、クリープ防止部材が軸受と一体成型されているので、部品点数の削減、組立工程の簡略、組み付け間違いなどの危険回避が可能である。   In addition, since the anti-creep member is integrally formed with the bearing compared to the conventional anti-creep rolling bearing made of a resin band, it is possible to reduce the number of parts, simplify the assembly process, and avoid dangers such as assembly errors.

さらに、クリープ防止部材が軸受幅と同等以上の幅を持つので、クリープ防止のために機能する面積が大きく、過酷な使用条件であっても、クリープ防止機能を十分に発揮することが可能である。   Furthermore, since the anti-creep member has a width equal to or greater than the bearing width, the area that functions to prevent creep is large, and the anti-creep function can be sufficiently exerted even under severe use conditions. .

図１は、本発明の第１実施形態を示している。本発明のクリープ防止転がり軸受は、アルミニウム合金製で円筒状の内周面を有するハウジングの内側に嵌合固定した転がり軸受の外輪が、このハウジングに対して回転する、所謂クリープの発生を防止するものである。   FIG. 1 shows a first embodiment of the present invention. The anti-creep rolling bearing of the present invention prevents the occurrence of so-called creep in which the outer ring of the rolling bearing fitted and fixed inside the housing made of aluminum alloy and having a cylindrical inner peripheral surface rotates with respect to the housing. Is.

本発明のクリープ防止転がり軸受１１は、内周面に外輪軌道を有する外輪１３と、外周面に内輪軌道を有する内輪２と、上記外輪軌道と内輪軌道との間に転動自在に設けられた複数の転動体４と、転動体４を保持する保持器５とを備えている。外輪１３の外周面から側面にかけて、合成樹脂製のクリープ防止部材１６が射出成形（例えば、インサート成形）により外輪１３と一体に成形されている。   The anti-creep rolling bearing 11 of the present invention is provided between an outer ring 13 having an outer ring raceway on an inner peripheral surface, an inner ring 2 having an inner ring raceway on an outer peripheral surface, and the outer ring raceway and the inner ring raceway. A plurality of rolling elements 4 and a cage 5 that holds the rolling elements 4 are provided. A synthetic resin creep prevention member 16 is integrally formed with the outer ring 13 by injection molding (for example, insert molding) from the outer peripheral surface to the side surface of the outer ring 13.

クリープ防止部材１６の材料は、ハウジング９の材料であるアルミニウム合金よりも熱膨張係数の大きい合成樹脂が用いられている。特に、耐熱性に優れていると共に線膨張係数が高く、吸水等による著しい寸法変化のない事などを考慮して、ポリアミド９Ｔを採用することが好ましい。しかしながら、ポリアミド９Ｔに限定されるものではなく、たとえば、ナイロン（ポリアミド樹脂）やポリエーテルサルフォン、ポリアセタール樹脂、ポリブチレンテレフタレート（ＰＢＴ）樹脂、エチレン−テトラフルオロエチレン共重合体（ＥＴＦＥ）、テトラフルオロエチレン−パーフルオロアルキルビニルエーテル共重合体（ＰＦＡ）など、単独の樹脂または２種以上の混合樹脂を用い、適宜に添加剤を配合して成形できる樹脂組成物を採用することができる。   As the material of the creep preventing member 16, a synthetic resin having a thermal expansion coefficient larger than that of the aluminum alloy that is the material of the housing 9 is used. In particular, it is preferable to use polyamide 9T in consideration of excellent heat resistance and a high linear expansion coefficient and no significant dimensional change due to water absorption. However, it is not limited to polyamide 9T. For example, nylon (polyamide resin), polyethersulfone, polyacetal resin, polybutylene terephthalate (PBT) resin, ethylene-tetrafluoroethylene copolymer (ETFE), tetrafluoro A resin composition that can be molded by using an individual resin or two or more kinds of mixed resins such as ethylene-perfluoroalkyl vinyl ether copolymer (PFA) and appropriately adding additives can be employed.

クリープ防止転がり軸受１１は、内輪２を回転軸８の嵌合部外周面８ａに一体回転可能に嵌合するとともに、クリープ防止部材１６を介して外輪１３をアルミニウム合金製のハウジング９に設けられた嵌合部内周面９ａに嵌合することにより、回転軸８を回転自在に支承している。このとき、クリープ防止部材１６は、ハウジングの嵌合部内周面９ａと外輪１３に押圧され、弾性力が径方向に発生し、摩擦係合力によってハウジング９と外輪１３を固定することができる。   The anti-creep rolling bearing 11 has the inner ring 2 fitted to the fitting portion outer peripheral surface 8a of the rotary shaft 8 so as to be integrally rotatable, and the outer ring 13 is provided in the aluminum alloy housing 9 via the creep preventing member 16. The rotary shaft 8 is rotatably supported by fitting to the fitting portion inner peripheral surface 9a. At this time, the creep preventing member 16 is pressed by the fitting portion inner peripheral surface 9a of the housing and the outer ring 13, elastic force is generated in the radial direction, and the housing 9 and the outer ring 13 can be fixed by the frictional engagement force.

ここで、ハウジング９の材料であるアルミニウム合金の熱膨張率は、外輪１３の材料である軸受鋼の熱膨張率よりも大きい。そのため、温度上昇に伴い、ハウジングの嵌合部内周面９ａと外輪１３の径方向間隔が広がることとなる。このとき、クリープ防止部材１６の熱膨張係数は、軸受鋼の熱膨張率よりも大きく、また、アルミニウム合金の熱膨張係数よりも大きいので、ハウジングの嵌合部内周面９ａと外輪１３の径方向間隔の広がる大きさよりも、クリープ防止部材１６の体積膨張量の方が大きくなる。従がって、温度が上昇しても、径方向に働く弾性力は低下することなく、外輪１３のハウジング９に対する嵌合状態を維持することが出来る。   Here, the thermal expansion coefficient of the aluminum alloy that is the material of the housing 9 is larger than the thermal expansion coefficient of the bearing steel that is the material of the outer ring 13. Therefore, the radial interval between the fitting portion inner peripheral surface 9a of the housing and the outer ring 13 increases as the temperature rises. At this time, the coefficient of thermal expansion of the creep preventing member 16 is larger than the coefficient of thermal expansion of the bearing steel and larger than the coefficient of thermal expansion of the aluminum alloy, so the radial direction of the fitting portion inner peripheral surface 9a and the outer ring 13 of the housing The volume expansion amount of the creep preventing member 16 is larger than the size of the interval. Accordingly, even when the temperature rises, the elastic force acting in the radial direction does not decrease, and the fitting state of the outer ring 13 with respect to the housing 9 can be maintained.

図２は、本発明の第２実施形態を示している。本発明のクリープ防止転がり軸受は、第１実施形態と同じく、アルミニウム合金製で円筒状の内周面を有するハウジングの内側に嵌合固定した転がり軸受の外輪が、このハウジングに対して回転する、所謂クリープの発生を防止するものである。   FIG. 2 shows a second embodiment of the present invention. In the creep-preventing rolling bearing of the present invention, as in the first embodiment, the outer ring of the rolling bearing fitted and fixed inside the housing made of aluminum alloy and having a cylindrical inner peripheral surface rotates with respect to the housing. This prevents the occurrence of so-called creep.

本発明のクリープ防止転がり軸受２１は、内周面に外輪軌道を有する外輪２３と、外周面に内輪軌道を有する内輪２と、上記外輪軌道と内輪軌道との間に転動自在に設けられた複数の転動体４と、転動体４を保持する保持器５とを備えている。外輪２３の外周面には、第1実施例とは異なり、外輪２３の軸方向幅と同等の幅に、合成樹脂製のクリープ防止部材２６が射出成形（例えば、インサート成形）により外輪２３と一体に成形されている。クリープ防止部材２６の材料は、第１実施形態と同じであるので、説明を省略する。   The creep preventing rolling bearing 21 of the present invention is provided between an outer ring 23 having an outer ring raceway on an inner peripheral surface, an inner ring 2 having an inner ring raceway on an outer peripheral surface, and the outer ring raceway and the inner ring raceway. A plurality of rolling elements 4 and a cage 5 that holds the rolling elements 4 are provided. Unlike the first embodiment, a synthetic resin creep prevention member 26 is integrally formed with the outer ring 23 on the outer peripheral surface of the outer ring 23 by injection molding (for example, insert molding) to a width equal to the axial width of the outer ring 23. It is molded into. Since the material of the creep preventing member 26 is the same as that of the first embodiment, the description thereof is omitted.

クリープ防止転がり軸受２１は、内輪２を回転軸８の嵌合部外周面８ａに一体回転可能に嵌合するとともに、クリープ防止部材２６を介して外輪２３をアルミニウム合金製のハウジング９に設けられた嵌合部内周面９ａに嵌合することにより、回転軸８を回転自在に支承している。このとき、クリープ防止部材２６は、ハウジングの嵌合部内周面９ａと外輪２３に押圧され、弾性力が径方向に発生し、摩擦係合力によってハウジング９と外輪２３を固定することができる。温度が上昇した際の、作用効果は、第１の実施の形態と同じであるので、説明を省略する。   The anti-creep rolling bearing 21 has the inner ring 2 fitted to the fitting portion outer peripheral surface 8a of the rotary shaft 8 so as to be integrally rotatable, and the outer ring 23 is provided in the aluminum alloy housing 9 via a creep preventing member 26. The rotary shaft 8 is rotatably supported by fitting to the fitting portion inner peripheral surface 9a. At this time, the creep preventing member 26 is pressed by the fitting portion inner peripheral surface 9a of the housing and the outer ring 23, and elastic force is generated in the radial direction, so that the housing 9 and the outer ring 23 can be fixed by the frictional engagement force. Since the effect when the temperature rises is the same as that of the first embodiment, the description thereof is omitted.

本発明のクリープ防止転がり軸受は、各種機械装置の回転支持部において使用することが可能であり、特に、オルタネータやカーエアコン用コンプレッサ等の自動車用の各種補機の回転支持部に使用する転がり軸受として好適に使用できる。   The creep-preventing rolling bearing of the present invention can be used in a rotation support portion of various mechanical devices, and in particular, a rolling bearing used in a rotation support portion of various auxiliary equipments for automobiles such as an alternator and a compressor for a car air conditioner. Can be suitably used.
