Description

本発明は、一般産業機械等に使用し、セパレータ保持器を備え、特にころを多数化できるころ軸受に関する。   The present invention relates to a roller bearing that is used in general industrial machinery and the like and includes a separator cage, and in particular, can have a large number of rollers.

セパレータ保持器を備えたセパレータ保持器付円筒ころ軸受の従来例としては、特許文献１に示すように、外輪および内輪間に複数の円筒ころが配置されたころ軸受において、前記各ころ間にはセパレータ保持器が介装されているとともに、前記各セパレータ保持器における前記各ころの軸方向に沿った移動を規制する手段が設けられている。
特開平1１−２８０７６９号公報 As a conventional example of a cylindrical roller bearing with a separator cage provided with a separator cage, as shown in Patent Document 1, in a roller bearing in which a plurality of cylindrical rollers are arranged between an outer ring and an inner ring, A separator holder is interposed, and means for restricting movement of each roller in the separator holder along the axial direction is provided.
JP-A-11-280769

しかしながら、特許文献１に於いては、ころ軸受の組立ての都合上、最後に配置されるセパレータ保持器は、弾性変形が可能となるように、スリットを入れる等、特別な加工を施す必要がある。   However, in Patent Document 1, for the convenience of assembling roller bearings, the separator holder disposed at the end needs to be specially processed such as slitting so that elastic deformation is possible. .

その結果、コストアップ要因になるとともに、セパレータ保持器の強度低下といったことが懸念される。   As a result, the cost increases and there is a concern that the strength of the separator cage is reduced.

さらに、ころ案内保持器のため、保持器ポケット面をころ半径と略同一の曲率を有する曲面形状に加工する必要があり、特に金属で形成する場合には、加工コストの高騰を招来するといったことがある。   Furthermore, because of the roller guide cage, it is necessary to machine the cage pocket surface into a curved surface shape having a curvature substantially the same as the radius of the roller, especially when it is made of metal, resulting in increased machining costs. There is.

本発明は、上述したような事情に鑑みてなされたものであって、セパレータ保持器にスリット等、特別な加工を施す必要がなく、また、ポケット面を平面もしくは平面に近い形状にすることで、たとえ金属でセパレータ保持器を形成する場合においても、容易に加工することができ、コストダウンを図るとともに、強度の低下を防止することができる、ころ軸受を提供することを目的とする。   The present invention has been made in view of the circumstances as described above, and it is not necessary to perform special processing such as slits on the separator cage, and the pocket surface is formed into a plane or a shape close to a plane. An object of the present invention is to provide a roller bearing that can be easily processed even when the separator cage is made of metal, can reduce costs, and can prevent a decrease in strength.

上記の目的を達成するため、本発明に係るころ軸受は、外輪及び内輪間に、複数のころを転動自在に介装し、隣接するころ間に、セパレータ保持器を配置したころ軸受に於いて、
前記セパレータ保持器は、
隣接するころ間に、略軸方向に沿って配置する柱部と、
当該柱部の側方に、前記ころの端面に対向するように設けた側板部と、を有し、
当該側板部に、前記ころの端面の逃げ部に係合する突起部が設けてあることを特徴とする。 In order to achieve the above object, a roller bearing according to the present invention is a roller bearing in which a plurality of rollers are movably interposed between an outer ring and an inner ring, and a separator cage is disposed between adjacent rollers. And
The separator holder is
Between adjacent rollers, a pillar portion arranged substantially along the axial direction;
A side plate provided on the side of the column so as to face the end face of the roller,
The side plate portion is provided with a protrusion that engages with a relief portion of the end face of the roller.

好適には、前記外輪及び内輪の両方に、少なくとも１個の鍔を有する。   Preferably, both the outer ring and the inner ring have at least one hook.

本発明によれば、ころの端面に設けてある逃げ部において、セパレータ保持器を保持する構造にすることにより、セパレータ保持器の軸方向への移動を規制しているとともに、保持器ポケット面を平面もしくは平面に近い形状にした場合においても、セパレータ保持器が脱落する虞れは無い。   According to the present invention, in the relief portion provided on the end face of the roller, the separator retainer is held, thereby restricting the movement of the separator retainer in the axial direction and the retainer pocket surface. Even in the case of a flat shape or a shape close to a flat surface, there is no possibility that the separator cage will drop off.

従って、セパレータ保持器にスリット等、特別な加工を施す必要がなく、また、ポケット面を平面もしくは平面に近い形状にすることで、たとえ金属でセパレータ保持器を形成する場合においても、容易に加工することができ、コストダウンを図るとともに、強度の低下を防止することができる。   Therefore, there is no need to apply special processing such as slits to the separator cage, and it is easy to process even when the separator cage is made of metal by making the pocket surface flat or nearly flat. Thus, the cost can be reduced and the strength can be prevented from decreasing.

以下、本発明の実施の形態に係るころ軸受を図面を参照しつつ説明する。   Hereinafter, a roller bearing according to an embodiment of the present invention will be described with reference to the drawings.

（第１実施の形態）
図１（ａ）は、本発明の第１実施の形態に係るころ軸受に装着するセパレータ保持器の斜視図であり、（ｂ）は、その側面図である。 (First embodiment)
Fig.1 (a) is a perspective view of the separator holder | retainer with which the roller bearing which concerns on 1st Embodiment of this invention is mounted | worn, (b) is the side view.

外輪（図示略）および内輪（図示略）間に、複数のころ１が配置してある。隣接するころ１，１間に、多数のセパレータ保持器２が配置してある。   A plurality of rollers 1 are arranged between an outer ring (not shown) and an inner ring (not shown). A number of separator holders 2 are arranged between the adjacent rollers 1 and 1.

セパレータ保持器２は、隣接するころ１，１間に、略軸方向に沿って配置する柱部３と、柱部３の側方に、ころ１の端面に対向するように設けた一対の側板部４，４と、を有ししてる。   The separator retainer 2 includes a column portion 3 disposed substantially along the axial direction between the adjacent rollers 1 and 1, and a pair of side plates provided on the side of the column portion 3 so as to face the end surface of the roller 1. Parts 4 and 4.

一対の側板部４，４の一方は、一方のころ１の端面に対向するように配置してあり、他方の側板部４は、隣接する他方のころ１の反対側の端面に対向するように配置してある。   One of the pair of side plate portions 4, 4 is disposed so as to face the end surface of one roller 1, and the other side plate portion 4 is opposed to the end surface on the opposite side of the adjacent other roller 1. It is arranged.

本実施の形態では、側板部４に、ころ１の端面の逃げ部５（凹段部）に係合する突起部６が設けてある。   In the present embodiment, the side plate portion 4 is provided with a protruding portion 6 that engages with a relief portion 5 (concave step portion) on the end surface of the roller 1.

このように、側板部４の突起部６を、ころ１の端面の逃げ部５に係合し、この逃げ部５にセパレータ保持器２を保持する構造にしている。そのため、セパレータ保持器２の軸方向への移動を規制できるとともに、保持器ポケット面を平面もしくは平面に近い形状にした場合においても、セパレータ保持器２が脱落する虞れは無い。   In this way, the protrusion 6 of the side plate 4 is engaged with the relief 5 on the end face of the roller 1, and the separator holder 2 is held by the relief 5. Therefore, the movement of the separator cage 2 in the axial direction can be restricted, and there is no possibility that the separator cage 2 will fall off even when the cage pocket surface is flat or nearly flat.

すなわち、セパレータ保持器２がころ１の端面との間でパチン結合していることから、保持器ポケット部ところ１との接触部を平面もしくは平面に近い形伏にすることを可能にするとともに、スリット等の特殊加工を施すことなく容易に軸受の組立が可能となる。この結果、セパレータ保持器２の製作コストを低減するだけでなく、セパレータ保持器２の強度の低下を防止することが可能となる。   That is, since the separator cage 2 is snap-bonded with the end face of the roller 1, it is possible to make the contact portion with the cage pocket portion 1 flat or nearly flat. The bearing can be easily assembled without applying special processing such as slitting. As a result, it is possible not only to reduce the manufacturing cost of the separator holder 2 but also to prevent the strength of the separator holder 2 from being lowered.

なお、本実施の形態では、ころ１の端面に、逃げ部５の形成が容易であることから、ころ径が１０ｍｍ以上のもの（即ち、ころ径がある程度大きいもの）に対して特に有効である。   In this embodiment, since the relief portion 5 can be easily formed on the end face of the roller 1, it is particularly effective for a roller having a roller diameter of 10 mm or more (that is, a roller having a large diameter). .

（第２実施の形態）
図２は、本発明の第２実施の形態に係るころ軸受に装着するセパレータ保持器の側面図である。 (Second Embodiment)
FIG. 2 is a side view of a separator cage attached to the roller bearing according to the second embodiment of the present invention.

本実施の形態では、一対の側板部４，４は、第１実施の形態と異なり、同じころ１の両方の端面に対向するように設けてある。   In the present embodiment, unlike the first embodiment, the pair of side plate portions 4 and 4 are provided to face both end surfaces of the same roller 1.

また、本実施の形態の場合には、セパレータ保持器２は、内輪または外輪において案内される。   In the case of this embodiment, separator holder 2 is guided in the inner ring or the outer ring.

本実施の形態に於いても、側板部４に、ころ１の端面の逃げ部５に係合する突起部６が設けてある。   Also in the present embodiment, the side plate portion 4 is provided with the protruding portion 6 that engages with the relief portion 5 on the end surface of the roller 1.

本実施の形態の作用・効果は、上述した実施の形態と同様である。   The operations and effects of the present embodiment are the same as those of the above-described embodiment.

（第３実施の形態）
図３は、本発明の第３実施の形態に係るころ軸受に装着するセパレータ保持器の斜視図である。 (Third embodiment)
FIG. 3 is a perspective view of a separator cage attached to the roller bearing according to the third embodiment of the present invention.

本実施の形態では、突起部６は、側板部４と別体に構成してある。即ち、側板部４に、ピン穴７が設けてあり、このピン穴７に、突起部としてのピン６が挿入してある。   In the present embodiment, the protruding portion 6 is configured separately from the side plate portion 4. That is, a pin hole 7 is provided in the side plate portion 4, and a pin 6 as a protrusion is inserted into the pin hole 7.

本実施の形態の作用・効果は、上述した実施の形態と同様である。   The operations and effects of the present embodiment are the same as those of the above-described embodiment.

（第４実施の形態）
図４（ａ）は、本発明の第４実施の形態に係るころ軸受に装着するセパレータ保持器の斜視図であり、（ｂ）は、ころに、逃げ部（凹段部）を形成した斜視図であり、（ｃ）は、ころに、中空穴を形成した斜視図である。 (Fourth embodiment)
FIG. 4A is a perspective view of a separator cage to be mounted on a roller bearing according to a fourth embodiment of the present invention, and FIG. 4B is a perspective view in which a relief portion (concave step portion) is formed on the roller. It is a figure and (c) is the perspective view which formed the hollow hole in the roller.

上記の実施の形態では、図４（ｂ）に示すように、ころ１の端面に、逃げ部５（凹段部）が形成してあるが、本実施の形態では、図４（ｃ）に示すように、ころ１に、中空穴８が形成してある。   In the above embodiment, as shown in FIG. 4B, the escape portion 5 (concave step portion) is formed on the end face of the roller 1, but in the present embodiment, in FIG. As shown, a hollow hole 8 is formed in the roller 1.

特に、ころ１の径がおよそ４０ｍｍを超える場合においては、標準の円筒ころ軸受においては、中空穴を用いたピンタイプ保持器が採用されることが多い。このため、ころ１の径が４０ｍｍを越えるような場合においては、部品の共通化によるコストメリットがある。   In particular, when the diameter of the roller 1 exceeds approximately 40 mm, a pin type cage using a hollow hole is often adopted in a standard cylindrical roller bearing. For this reason, when the diameter of the roller 1 exceeds 40 mm, there is a cost merit due to the common use of parts.

本実施の形態の作用・効果は、上述した実施の形態と同様である。   The operations and effects of the present embodiment are the same as those of the above-described embodiment.

（第５実施の形態）
図５は、本発明の第５実施の形態に係るころ軸受に装着するセパレータ保持器の斜視図である。 (Fifth embodiment)
FIG. 5 is a perspective view of a separator cage attached to a roller bearing according to a fifth embodiment of the present invention.

本実施の形態では、セパレータ保持器２と、ころ１との間の接触面圧を下げるため、ポケット部９の形状は、曲面形状に形成してある。   In the present embodiment, in order to reduce the contact surface pressure between the separator cage 2 and the roller 1, the shape of the pocket portion 9 is formed in a curved surface shape.

本実施の形態の作用・効果は、上述した実施の形態と同様である。   The operations and effects of the present embodiment are the same as those of the above-described embodiment.

（第６実施の形態）
図６は、本発明の第６実施の形態に係るころ軸受に装着するセパレータ保持器の側面図である。 (Sixth embodiment)
FIG. 6 is a side view of a separator cage attached to the roller bearing according to the sixth embodiment of the present invention.

本実施の形態では、セパレータ保持器２は、内輪の鍔、または外輪の鍔にて案内される。このため、特に、外輪の鍔との接触部１０においては、角部を曲面形状もしくはだらし加工を施すことが、特に効果的である。   In the present embodiment, separator holder 2 is guided by the inner ring or the outer ring. For this reason, in particular, in the contact portion 10 with the flange of the outer ring, it is particularly effective to subject the corner portion to a curved surface shape or a slacking process.

本実施の形態の作用・効果は、上述した実施の形態と同様である。   The operations and effects of the present embodiment are the same as those of the above-described embodiment.

なお、本発明は、上述した実施の形態に限定されず、種々変形可能である。また、セパレータ保持器の腕部に、凹部または貫通穴を設け、ころの端面に、凸部を設けて、パチン結合しても、上記の実施の形態と同様の効果を得ることができる。さらに、セパレータ保持器は、円筒ころ軸受に限らず、他の転がり軸受にも適用可能である。   In addition, this invention is not limited to embodiment mentioned above, A various deformation | transformation is possible. Further, even if a recess or a through hole is provided in the arm portion of the separator cage, and a protrusion is provided on the end face of the roller and snap-bonded, the same effect as in the above embodiment can be obtained. Furthermore, the separator cage is not limited to the cylindrical roller bearing, but can be applied to other rolling bearings.
