Abstract

<P>PROBLEM TO BE SOLVED: To surely prevent the occurrence of metallic noises due to collision between a rolling element and the raceway surface of a bearing ring even when vibration from the outside is propagated to the inside of a bearing. <P>SOLUTION: Between a raceway surface 2a of an outer ring 2 of the deep groove ball bearing and a ball 3, an O-ring 7 is laid as an elastic body which is mounted in an annular groove 6 in a non-load region on the raceway surface 2a having no contact with the ball 3. Thus, the interference operation of the O-ring 7 surely prevents the occurrence of metallic noises due to collision between the ball 3 and each of the raceway surfaces 1a, 2a of an inner ring 1 and the outer ring 2 even when vibration from the outside is propagated to the inside of the bearing. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、転がり軸受に関し、特に、外部から振動を受ける部位に使用されるものに好適な転がり軸受に関する。   The present invention relates to a rolling bearing, and more particularly to a rolling bearing suitable for one used for a part that receives vibration from the outside.

エンジンのクランク軸やミシンのカム軸等を支持する転がり軸受のように、外部から振動を受ける部位に使用されるものでは、軸受内部に伝播される振動によって、転動体が軌道輪の軌道面と小刻みに衝突し、甲高い金属音の騒音が発生することがある。この金属音の騒音は、アンギュラ玉軸受や円錐ころ軸受のように、予圧を付与されて軸受内部隙間が殺されるものではあまり発生せず、深溝玉軸受や内外輪の一方の軌道輪のみを有する転がり軸受等のように、予圧を付与できず、軸受内部隙間によるガタが存在するもので発生しやすい。   For rolling bearings that support vibrations from the outside, such as rolling bearings that support engine crankshafts, camshafts of sewing machines, etc., the rolling elements are caused to contact the raceway surface of the bearing ring by vibrations propagated inside the bearings. Collisions may occur and high-pitched metal noises may be generated. The noise of this metal sound does not occur so much when the preload is applied and the internal clearance of the bearing is killed, such as an angular ball bearing or a tapered roller bearing, and it has only a deep groove ball bearing or one of the inner and outer rings. Like a rolling bearing or the like, preload cannot be applied, and there is a backlash due to a clearance inside the bearing, which is likely to occur.

なお、小型エンジンのクランク軸を支持する転がり軸受を対象として、外輪の外径面の全周に弾性体を配設し、ハウジングの内径面の円筒度等の加工精度が悪くても、弾性体の変形によって外輪とハウジング間の隙間を埋めるようにしたものがある（例えば、特許文献１参照）。   For rolling bearings that support the crankshaft of a small engine, an elastic body is provided on the entire circumference of the outer diameter surface of the outer ring, and even if the processing accuracy such as the cylindricity of the inner diameter surface of the housing is poor, the elastic body There is one in which a gap between the outer ring and the housing is filled by the deformation of (see, for example, Patent Document 1).

特開平１０−８９８２号公報JP-A-10-8982

上述した転動体と軌道輪の軌道面との衝突による金属音の発生を防止するためには、特許文献１に記載されたもののように、外輪の外径面の全周に弾性体を配設することが考えられる。しかしながら、外輪の外径面に配設した弾性体は、外部からの振動の振幅をある程度軽減できるが、軸受内部への振動の伝播を遮断することはできず、金属音の発生を確実に防止することはできない。また、外輪の外径寸法が弾性体を配設した分だけ大きくなり、これを防止するために外輪の金属部の肉厚を薄くすると、軸受の剛性が低下する問題もある。   In order to prevent the generation of metal sound due to the collision between the rolling element and the raceway of the raceway, an elastic body is disposed around the entire outer diameter surface of the outer race as described in Patent Document 1. It is possible to do. However, the elastic body arranged on the outer diameter surface of the outer ring can reduce the amplitude of vibration from the outside to some extent, but it cannot block the propagation of vibration to the inside of the bearing and reliably prevent the generation of metallic noise. I can't do it. In addition, the outer diameter of the outer ring is increased by the amount of the elastic body, and if the thickness of the metal part of the outer ring is reduced to prevent this, there is a problem that the rigidity of the bearing is lowered.

そこで、本発明の課題は、外部からの振動が軸受内部に伝播されても、転動体と軌道輪の軌道面との衝突による金属音の騒音の発生を確実に防止できるようにすることである。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reliably prevent the generation of metal noise due to a collision between a rolling element and a raceway surface of a raceway even when external vibration is propagated inside the bearing. .

上記の課題を解決するために、本発明は、内輪および外輪の少なくとも一方の軌道輪を有し、この軌道輪の軌道面に複数の転動体を配列した転がり軸受において、前記軌道輪の軌道面と前記転動体との間に弾性体を介在させた構成を採用した。   In order to solve the above-described problems, the present invention provides a rolling bearing having at least one raceway of an inner ring and an outer race, and a plurality of rolling elements arranged on the raceway surface of the raceway. And a configuration in which an elastic body is interposed between the rolling elements.

すなわち、軌道輪の軌道面と転動体との間に弾性体を介在させることにより、外部からの振動が軸受内部に伝播されても、この弾性体の干渉作用によって、転動体と軌道輪の軌道面との衝突による金属音の騒音の発生を確実に防止できるようにした。また、この転がり軸受は、転動体と軌道輪の軌道面との衝突を防止することによって、転動体の表面や軌道輪の軌道面におけるフレッティング等の表面損傷の発生も抑制することができる。   That is, by interposing an elastic body between the raceway surface of the raceway and the rolling element, even if vibration from the outside is propagated inside the bearing, the raceway between the rolling element and the raceway is caused by the interference action of this elastic body. The metal noise caused by the collision with the surface can be surely prevented. Moreover, this rolling bearing can also suppress the occurrence of surface damage such as fretting on the surface of the rolling element and the raceway surface of the raceway by preventing the rolling element from colliding with the raceway surface of the raceway.

前記軌道輪の軌道面が軸方向に曲率を付与され、前記転動体が接触しない非負荷域が軸方向で存在するものである場合は、前記弾性体をこの非負荷域で前記転動体との間に介在させることにより、軸受負荷による弾性体の損傷を防止することができる。   When the raceway surface of the raceway is given a curvature in the axial direction and a non-load region where the rolling element does not contact exists in the axial direction, the elastic body is connected to the rolling element in the non-load region. By interposing them in between, it is possible to prevent the elastic body from being damaged by the bearing load.

前記転がり軸受が内輪と外輪の両方の軌道輪を有し、これらの内輪と外輪の軌道面と前記転動体との間に、前記弾性体を転動体中心に対して同じ側で介在させることにより、弾性体を組み込みやすくすることができる。   The rolling bearing has both inner and outer ring raceways, and the elastic body is interposed between the raceway surfaces of the inner and outer rings and the rolling element on the same side with respect to the rolling element center. The elastic body can be easily incorporated.

前記転がり軸受が内輪と外輪の両方の軌道輪を有し、これらの内輪と外輪の軌道面と前記転動体との間に、前記弾性体を転動体中心に対して反対側で介在させることにより、アキシアル方向の振動の伝播に対しても、転動体と軌道輪の軌道面との衝突による金属音の騒音の発生を防止することができる。   The rolling bearing has both inner and outer ring raceways, and the elastic body is interposed between the raceway surfaces of the inner and outer rings and the rolling element on the opposite side to the rolling element center. In addition, even with respect to the propagation of vibration in the axial direction, it is possible to prevent the generation of metal noise due to the collision between the rolling element and the raceway surface of the raceway.

前記弾性体を、前記軌道面に設けた環状溝に装着したＯリングとすることにより、軌道輪の軌道面と転動体との間に弾性体を容易に介在させることができる。   When the elastic body is an O-ring mounted in an annular groove provided on the raceway surface, the elastic body can be easily interposed between the raceway surface of the raceway and the rolling element.

本発明の転がり軸受は、軌道輪の軌道面と転動体との間に弾性体を介在させたので、外部からの振動が軸受内部に伝播されても、この弾性体の干渉作用によって、転動体と軌道輪の軌道面との衝突による金属音の騒音の発生を確実に防止することができる。また、この転がり軸受は、転動体と軌道輪の軌道面との衝突を防止することによって、転動体の表面や軌道輪の軌道面におけるフレッティング等の表面損傷の発生も抑制することができる。   In the rolling bearing of the present invention, an elastic body is interposed between the raceway surface of the bearing ring and the rolling element. Therefore, even if vibration from the outside is propagated inside the bearing, the rolling element is caused by the interference action of the elastic body. It is possible to reliably prevent the generation of metal noise due to the collision between the raceway and the raceway surface. Moreover, this rolling bearing can also suppress the occurrence of surface damage such as fretting on the surface of the rolling element and the raceway surface of the raceway by preventing the rolling element from colliding with the raceway surface of the raceway.

前記軌道輪の軌道面が軸方向に曲率を付与され、転動体が接触しない非負荷域が軸方向で存在するものである場合は、弾性体をこの非負荷域で転動体との間に介在させることにより、軸受負荷による弾性体の損傷を防止することができる。   When the raceway surface of the raceway is given a curvature in the axial direction and there is a non-load area in the axial direction where the rolling elements do not contact, an elastic body is interposed between the rolling elements in the non-load area. By doing so, it is possible to prevent the elastic body from being damaged by the bearing load.

前記転がり軸受が内輪と外輪の両方の軌道輪を有し、これらの内輪と外輪の軌道面と転動体との間に、弾性体を転動体中心に対して同じ側で介在させることにより、弾性体を組み込みやすくすることができる。   The rolling bearing has both inner and outer ring raceways, and an elastic body is interposed between the raceways of the inner ring and the outer ring and the rolling element on the same side with respect to the rolling element center. The body can be easily incorporated.

前記転がり軸受が内輪と外輪の両方の軌道輪を有し、これらの内輪と外輪の軌道面と転動体との間に、弾性体を転動体中心に対して反対側で介在させることにより、アキシアル方向の振動の伝播に対しても、転動体と軌道輪の軌道面との衝突による金属音の騒音の発生を防止することができる。   The rolling bearing has both inner and outer ring raceways, and an elastic body is interposed between the inner race and the outer raceway raceway and the rolling element on the opposite side of the rolling element center. Even with respect to the propagation of vibration in the direction, it is possible to prevent the generation of metal noise due to the collision between the rolling elements and the raceway surface of the raceway.

前記弾性体を、軌道面に設けた環状溝に装着したＯリングとすることにより、軌道輪の軌道面と転動体との間に弾性体を容易に介在させることができる。   By making the elastic body an O-ring mounted in an annular groove provided on the raceway surface, the elastic body can be easily interposed between the raceway surface of the raceway and the rolling element.

以下、図面に基づき、本発明の実施形態を説明する。図１は第１の実施形態を示す。この転がり軸受は、内輪１の軌道面１ａと外輪２の軌道面２ａの間に、複数の転動体としてのボール３を保持器４に保持して配列した深溝玉軸受であり、軸受内部が両側のシール部材５でシールされている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment. This rolling bearing is a deep groove ball bearing in which a plurality of balls 3 as rolling elements are held in a cage 4 between a raceway surface 1 a of an inner ring 1 and a raceway surface 2 a of an outer ring 2. The sealing member 5 is sealed.

前記内輪１と外輪２の各軌道面１ａ、２ａは、軸方向に曲率を付与された軌道溝とされ、ボール３が接触しない非負荷域が軸方向中心の両側に存在しており、外輪２の軌道面２ａの両側の非負荷域に環状溝６が設けられ、これらの環状溝６に弾性体としてのフッ素ゴムで形成されたＯリング７が、軌道面２ａとボール３との間に介在するように装着されている。したがって、外部から振動が伝播されても、これらのＯリング７の干渉作用によって、ボール３が内輪１や外輪２の各軌道面１ａ、２ａと衝突することはなく、金属音の騒音の発生が確実に防止される。また、ボール３と各軌道面１ａ、２ａとの衝突によるフレッティング等の表面損傷の発生も抑制される。   Each raceway surface 1a, 2a of the inner ring 1 and the outer ring 2 is a raceway groove having a curvature in the axial direction, and a non-load region where the ball 3 does not contact exists on both sides of the center in the axial direction. Annular grooves 6 are provided in the non-load areas on both sides of the raceway surface 2a, and an O-ring 7 formed of fluororubber as an elastic body is interposed between the raceway surface 2a and the ball 3 in these annular grooves 6. It is installed to do. Therefore, even if vibration is propagated from the outside, the balls 3 do not collide with the raceway surfaces 1a and 2a of the inner ring 1 and the outer ring 2 due to the interference action of these O-rings 7, and the generation of noise of metal sound is generated. It is surely prevented. Further, the occurrence of surface damage such as fretting due to the collision between the ball 3 and the raceway surfaces 1a and 2a is also suppressed.

図２は第２の実施形態を示す。この転がり軸受も第１の実施形態のものと同様の深溝玉軸受であり、前記Ｏリング７が、内輪１の軌道面１ａおよび外輪２の軌道面２ａとボール３との間に、ボール３の中心に対して同じ側に介在するように装着されている。その他の部分は第１の実施形態のものと同じである。この実施形態では、各Ｏリング７を組み込みやすくすることができる。   FIG. 2 shows a second embodiment. This rolling bearing is also a deep groove ball bearing similar to that of the first embodiment, and the O-ring 7 is provided between the raceway surface 1 a of the inner ring 1 and the raceway surface 2 a of the outer ring 2 and the ball 3. It is mounted so as to be interposed on the same side with respect to the center. Other parts are the same as those of the first embodiment. In this embodiment, each O-ring 7 can be easily incorporated.

図３は第３の実施形態を示す。この転がり軸受も第１の実施形態のものと同様の深溝玉軸受であり、前記Ｏリング７が、内輪１の軌道面１ａおよび外輪２の軌道面２ａとボール３との間に、ボール３の中心に対して反対側に介在するように装着されている。その他の部分は第１の実施形態のものと同じである。この実施形態では、アキシアル方向の振動の伝播に対しても、ボール３と内外輪１、２の軌道面１ａ、２ａとの衝突による金属音の騒音の発生を防止することができる。   FIG. 3 shows a third embodiment. This rolling bearing is also a deep groove ball bearing similar to that of the first embodiment, and the O-ring 7 is provided between the raceway surface 1 a of the inner ring 1 and the raceway surface 2 a of the outer ring 2 and the ball 3. It is mounted so as to be interposed on the opposite side to the center. Other parts are the same as those of the first embodiment. In this embodiment, the generation of metal noise due to the collision between the ball 3 and the raceway surfaces 1a and 2a of the inner and outer rings 1 and 2 can be prevented even with respect to the propagation of vibration in the axial direction.

上述した各実施形態では、内輪と外輪を有する深溝玉軸受としたが、本発明に係る転がり軸受は、このような深溝玉軸受に限定されることはなく、他の玉軸受やころ軸受等にも適用することができ、内輪と外輪のいずれか一方の軌道輪のみを有する転がり軸受にも適用することができる。また、軌道輪の軌道面が軸方向に曲率を付与され、転動体が接触しない非負荷域が軸方向で存在する転がり軸受としては、ボールを転動体とする玉軸受のほかに、たる形ころを転動体とする自動調心ころ軸受等があり、このような軌道面に非負荷域が存在する転がり軸受には、特に好適である。   In each of the above-described embodiments, the deep groove ball bearing has an inner ring and an outer ring. However, the rolling bearing according to the present invention is not limited to such a deep groove ball bearing, and other ball bearings, roller bearings, and the like. The present invention can also be applied to a rolling bearing having only one of the inner ring and the outer ring. In addition to ball bearings using balls as rolling elements, rolling roller bearings are also available in which the raceway surface of the bearing ring is given a curvature in the axial direction and there is an unloaded area in the axial direction where the rolling elements do not contact. There is a self-aligning roller bearing having a rolling element as a rolling element, and is particularly suitable for such a rolling bearing having a non-load region on the raceway surface.

また、上述した各実施形態では、軌道輪の軌道面と転動体との間に介在させる弾性体をフッ素ゴムで形成されたＯリングとしたが、弾性体の種類と形状は実施形態のものに限定されることはない。   In each of the above-described embodiments, the elastic body interposed between the raceway surface of the raceway and the rolling element is an O-ring formed of fluoro rubber. However, the type and shape of the elastic body are the same as those of the embodiment. There is no limit.
