Description

本発明は、一方向に動力を伝達し、反対方向には空転する一方向クラッチに関する。   The present invention relates to a one-way clutch that transmits power in one direction and idles in the opposite direction.

従来、このような一方向クラッチとして、図３に示すように、互いに独立して回転可能に嵌められた内輪２及び外輪３と、内輪２及び外輪３との間に配置された係合部材４及びサポート軸受７と、内輪２及び外輪３間の空間をシールするように係合部材４及びサポート軸受７の両側に配置されるシール部材５等により構成されている一方向クラッチ１がある（例えば、特許文献１参照。）。   Conventionally, as such a one-way clutch, as shown in FIG. 3, an engagement member 4 disposed between an inner ring 2 and an outer ring 3 that are rotatably fitted to each other and an inner ring 2 and an outer ring 3. And the support bearing 7 and the one-way clutch 1 including the engagement member 4 and the seal members 5 disposed on both sides of the support bearing 7 so as to seal the space between the inner ring 2 and the outer ring 3 (for example, , See Patent Document 1).

このうちのサポート軸受７は、外輪３に加わるラジアル荷重を支承しつつ、内輪２と外輪３との相対回転が可能である。また、この一方向クラッチ１においては、外輪３が内輪２に対して所定方向に相対回転する場合にのみ、係合部材４が内輪２及び外輪３と係合し、外輪３から内輪２へ回転力が伝達される。   Of these, the support bearing 7 is capable of relative rotation between the inner ring 2 and the outer ring 3 while supporting a radial load applied to the outer ring 3. In this one-way clutch 1, the engaging member 4 engages with the inner ring 2 and the outer ring 3 only when the outer ring 3 rotates relative to the inner ring 2 in a predetermined direction, and rotates from the outer ring 3 to the inner ring 2. Power is transmitted.

この一方向クラッチ１の場合、耐久性を十分に確保する為に、実際には、一方向クラッチ１の内部に潤滑の為のオイル又はグリースが封入される。従って、これら一方向クラッチ１の内部に封入したオイル又はグリースが外部に漏洩し、一方向クラッチ１内部のオイル又はグリースの量が減少するのを防止する必要がある。
また、一方向クラッチ１の耐久性を十分に確保する為に、複数個の係合部材４がある一方向クラッチ１の内部空間内へ外部から泥水、塵芥等の異物が浸入するのを防止する必要もある。 In the case of this one-way clutch 1, in order to ensure sufficient durability, oil or grease for lubrication is actually enclosed in the one-way clutch 1. Therefore, it is necessary to prevent the oil or grease enclosed inside the one-way clutch 1 from leaking to the outside and reducing the amount of oil or grease inside the one-way clutch 1.
Further, in order to sufficiently ensure the durability of the one-way clutch 1, foreign matters such as muddy water and dust are prevented from entering the internal space of the one-way clutch 1 having a plurality of engaging members 4 from the outside. There is also a need.

この一方向クラッチ１は、シール部材５が、鋼板を円環状に形成したスラスト軸受５Ａと、ゴムやエラストマー等の弾性材からなるシール支持体５Ｂで構成されており、これにより、一方向クラッチ１の内部にあるオイル又はグリースが一方向クラッチ１の外部へ漏洩するのを防止するとともに、複数個の係合部材４がある一方向クラッチ１の内部空間内への異物の浸入防止を図ることができる。   In the one-way clutch 1, the seal member 5 includes a thrust bearing 5A in which a steel plate is formed in an annular shape, and a seal support 5B made of an elastic material such as rubber or elastomer. Is prevented from leaking to the outside of the one-way clutch 1 and also prevents foreign matter from entering the inner space of the one-way clutch 1 having a plurality of engaging members 4. it can.

しかし、この一方向クラッチ１は、スラスト軸受５Ａが鋼板を円環状に形成したものであることから、一方向クラッチ１の使用時に鋼板の温度が上昇したときに、鋼板が熱膨張により伸びて、スラスト軸受５Ａが一部溝から外れてしまうという問題があった。
また、スラスト軸受５Ａはシール支持体５Ｂに設けられた溝５Ｂ１に収納されるものであるが、スラスト軸受５Ａをシール支持体５Ｂの溝５Ｂ１にぴったり嵌合させるには、スラスト軸受５Ａを高い精度で加工する必要があり、そのために製造コストが高くなってしまうという問題があった。また、シール支持体５Ｂの溝５Ｂ１の寸法を大きめに取り、加工精度が高くなくともスラスト軸受５Ａがシール支持体５Ｂの溝５Ｂ１に嵌合できるようにすることも可能であるが、その場合、スラスト軸受５Ａがシール支持体５Ｂから外れやすくなるという問題が生じる。 However, this one-way clutch 1 is a thrust bearing 5A formed of a steel plate in an annular shape, so when the temperature of the steel plate rises when the one-way clutch 1 is used, the steel plate expands due to thermal expansion, There was a problem that the thrust bearing 5A was partially removed from the groove.
The thrust bearing 5A is housed in a groove 5B1 provided in the seal support 5B. In order to fit the thrust bearing 5A exactly in the groove 5B1 of the seal support 5B, the thrust bearing 5A is highly accurate. Therefore, there is a problem that the manufacturing cost becomes high. Further, it is possible to make the dimension of the groove 5B1 of the seal support 5B larger so that the thrust bearing 5A can be fitted into the groove 5B1 of the seal support 5B even if the processing accuracy is not high. There arises a problem that the thrust bearing 5A is easily detached from the seal support 5B.

これに対し、図４に示すような、一方向クラッチがある。
この一方向クラッチ１０Ａは、互いに回転可能な内輪１０２及び外輪１０３と、内輪１０２及び外輪１０３との間に配置された係合部材１０４と、内輪１０２及び外輪１０３間の係合部材１０４の両側に配置されるスラスト部材１０５により構成されているものであり、スラスト部材１０５は、複数の扇状樹脂プレート１０５Ａ１からなるスラスト軸受１０５Ａとスラスト支持体１０５Ｂからなり、スラスト軸受１０５Ａはスラスト支持体１０５Ｂに取付ボルトＢで固定されている。 On the other hand, there is a one-way clutch as shown in FIG.
The one-way clutch 10A includes an inner ring 102 and an outer ring 103 that are rotatable relative to each other, an engagement member 104 that is disposed between the inner ring 102 and the outer ring 103, and an engagement member 104 that is disposed between the inner ring 102 and the outer ring 103. The thrust member 105 includes a thrust bearing 105A composed of a plurality of fan-shaped resin plates 105A1 and a thrust support body 105B. The thrust bearing 105A is attached to the thrust support body 105B with mounting bolts. It is fixed with B.

図５に示すように、複数の扇状樹脂プレート１０５Ａ１は互い間隔を設けてスラスト支持体１０５Ｂに取付けられており、これにより、樹脂の温度上昇による伸びを吸収することができる。
また、スラスト軸受１０５Ａの扇状樹脂プレート１０５Ａ１には、取付ボルトＢを固定するためのボルト孔や座刳りが設けられる。さらに、扇状樹脂プレート１０５Ａ１をスラスト支持体１０５Ｂに取付ける際には、取付ボルトＢのゆるみ止めとして接着剤が塗布される。
これにより、スラスト軸受１０５Ａをスラスト支持体１０５Ｂに確実に固定することができる。
特開２０００−３３７４０５号公報 As shown in FIG. 5, the plurality of fan-shaped resin plates 105A1 are attached to the thrust support body 105B with a space between each other, whereby the elongation due to the temperature rise of the resin can be absorbed.
Further, the fan-shaped resin plate 105A1 of the thrust bearing 105A is provided with a bolt hole and a counterbore for fixing the mounting bolt B. Further, when the fan-shaped resin plate 105A1 is attached to the thrust support 105B, an adhesive is applied as a loosening stopper for the attachment bolt B.
Thereby, the thrust bearing 105A can be securely fixed to the thrust support 105B.
JP 2000-337405 A

しかし、この一方向クラッチ１０Ａでは、各扇状樹脂プレート１０５Ａ１を取付ボルトＢでスラスト支持体１０５Ｂに固定しなければならないことや、取付ボルトＢのゆるみ止めのために接着剤を塗布しなければならないことから、組立に手間と時間がかかるという問題があった。
また、スラスト軸受１０５Ａには、扇形の加工や取付ボルトＢ用のボルト孔、座刳りの加工を必要とするための加工が必要であることから、スラスト軸受１０５Ａの加工コストが高くなるという問題もあった。 However, in this one-way clutch 10A, each fan-shaped resin plate 105A1 must be fixed to the thrust support 105B with the mounting bolt B, and an adhesive must be applied to prevent the mounting bolt B from loosening. Therefore, there is a problem that assembly takes time and effort.
In addition, since the thrust bearing 105A requires processing for fan-shaped processing, bolt holes for the mounting bolts B, and processing of a counterbore, there is a problem that the processing cost of the thrust bearing 105A increases. there were.

本発明は、互いに回転可能な内輪及び外輪と、該内・外輪の間に配置された係合部材と、前記内輪及び外輪間の前記係合部材の両側に配置されるスラスト部材とを具える一方向クラッチにおいて、前記スラスト部材が樹脂製のスラスト軸受とスラスト支持体とからなり、該スラスト支持体に溝が設けられ、該溝に前記スラスト軸受が収納されていることを特徴とする一方向クラッチのスラスト軸受の保持構造によって、前記の課題を解決した。   The present invention includes an inner ring and an outer ring that are rotatable relative to each other, an engagement member disposed between the inner and outer rings, and a thrust member disposed on both sides of the engagement member between the inner ring and the outer ring. In the one-way clutch, the one-way clutch is characterized in that the thrust member includes a resin-made thrust bearing and a thrust support, a groove is provided in the thrust support, and the thrust bearing is accommodated in the groove. The above problem has been solved by the holding structure of the thrust bearing of the clutch.

本発明によれば、スラスト軸受が弾性体である樹脂からなるので、加工精度を高くしなくとも、スラスト軸受をスラスト支持体の溝にぴったり嵌合させることができる。また、スラスト軸受を取付ボルトによる固定が不要となり、樹脂からなるスラスト軸受を溝に嵌め込むだけの作業でよいので、組立の手間と時間を減らすことができる。   According to the present invention, since the thrust bearing is made of an elastic resin, the thrust bearing can be fitted into the groove of the thrust support body without increasing the processing accuracy. Further, since it is not necessary to fix the thrust bearing with mounting bolts, and it is only necessary to fit the thrust bearing made of resin into the groove, it is possible to reduce the labor and time of assembly.

本発明を図１及び図２に基づいて説明する。
本発明の一方向クラッチ１０は、互いに回転可能に設けられた内輪２０及び外輪３０と、内輪２０及び外輪３０との間に配置された係合部材４０及びローラケージ７０と、内輪２０及び外輪３０間の係合部材４０の両側に配置されるスラスト部材５０とを具えている。
スラスト部材５０は樹脂製のスラスト軸受５２とスラスト支持体５４とからなり、スラスト支持体５４にコの字型の溝５６が設けられ、この溝５６にスラスト軸受５２が収納されている。 The present invention will be described with reference to FIGS.
The one-way clutch 10 of the present invention includes an inner ring 20 and an outer ring 30 that are rotatably provided to each other, an engagement member 40 and a roller cage 70 that are disposed between the inner ring 20 and the outer ring 30, and the inner ring 20 and the outer ring 30. And a thrust member 50 disposed on both sides of the engagement member 40 therebetween.
The thrust member 50 includes a resin-made thrust bearing 52 and a thrust support 54, and a U-shaped groove 56 is provided in the thrust support 54, and the thrust bearing 52 is accommodated in the groove 56.

ここで、係合部材４０はスプラグであり、外輪３０が内輪２０に対して所定方向に相対回転する場合にのみ、係合部材４０が外輪３０と係合し、回転力が伝達される。
ローラケージ７０は、係合部材４０の両側にあり、一方向クラッチ１０に作用するラジアル荷重、すなわち、外輪３０の自重を支持しつつ、内輪２０と外輪３０との相対回転を行う。 Here, the engaging member 40 is a sprag, and only when the outer ring 30 rotates relative to the inner ring 20 in a predetermined direction, the engaging member 40 engages with the outer ring 30 and the rotational force is transmitted.
The roller cage 70 is on both sides of the engaging member 40 and performs relative rotation between the inner ring 20 and the outer ring 30 while supporting a radial load acting on the one-way clutch 10, that is, its own weight of the outer ring 30.

スラスト部材５０の外径部分は外輪３０と隙間嵌合し、スラスト方向では外輪３０の段差と止め輪６０で固定されている。スラスト部材５０の外径部分には、Ｏリング６２が装着され、オイル又はグリースをシールするとともに、摩擦力で外輪３０に固定される。また、これにより、一方向クラッチ１０が垂直方向に取付けられ大きなスラスト荷重が作用する場合でも、内輪２０端面とスラスト軸受５２間の摩擦抵抗よりも、スラスト支持体５４と止め輪６０の摩擦抵抗の方が大きいので、スラスト部材５０が外輪３０に対して回転することはない。
また、スラスト部材５０の内径部分にはオイルシール６４が装着され、Ｏリング６２とともに、一方向クラッチ１０の内部に封入したオイル又はグリースが外部に漏洩し、オイル又はグリースの量が減少したり、外部から一方向クラッチ１０の内部に泥水、塵芥等の異物が浸入したりするのを防止する。 The outer diameter portion of the thrust member 50 is fitted into the outer ring 30 with a gap, and is fixed by the step of the outer ring 30 and the retaining ring 60 in the thrust direction. An O-ring 62 is attached to the outer diameter portion of the thrust member 50, seals oil or grease, and is fixed to the outer ring 30 by a frictional force. This also allows the frictional resistance of the thrust support 54 and the retaining ring 60 to be greater than the frictional resistance between the end face of the inner ring 20 and the thrust bearing 52 even when the one-way clutch 10 is mounted vertically and a large thrust load acts. Therefore, the thrust member 50 does not rotate with respect to the outer ring 30.
In addition, an oil seal 64 is attached to the inner diameter portion of the thrust member 50, and the oil or grease sealed inside the one-way clutch 10 together with the O-ring 62 leaks to the outside, reducing the amount of oil or grease, This prevents foreign matter such as muddy water and dust from entering the inside of the one-way clutch 10 from the outside.

図２（ａ）に示すように、スラスト軸受５２は、断面が矩形の細長い棒状体で、十分な弾・塑性能を有するテフロン等の合成樹脂からなる。そして、スラスト軸受５２は、図２（ｂ）に示すように、温度上昇による樹脂の伸びを吸収するために、端部に適切な隙間を設けて溝５６に収納される。なお、この隙間は、スラスト軸受５２の長さをスラスト支持体５４の溝５６の全周よりも短い長さにすることで実現されるものである。   As shown in FIG. 2A, the thrust bearing 52 is an elongated rod-like body having a rectangular cross section, and is made of a synthetic resin such as Teflon having sufficient elastic / plastic performance. Then, as shown in FIG. 2B, the thrust bearing 52 is accommodated in the groove 56 with an appropriate gap provided at the end in order to absorb the elongation of the resin due to the temperature rise. This gap is realized by making the length of the thrust bearing 52 shorter than the entire circumference of the groove 56 of the thrust support 54.

なお、スラスト軸受５２は、図２（ｂ）で示すように一本の棒状体で構成するものに限るものではなく、例えば、図２（ｃ）に示すように、複数本の棒状体で構成してもよい。
また、図２（ｄ）に示すように、スラスト軸受５２の端部に面取り加工を施すことにより溝５６に嵌め込みやすくすることができる。 The thrust bearing 52 is not limited to one constituted by a single rod-shaped body as shown in FIG. 2 (b). For example, the thrust bearing 52 is constituted by a plurality of rod-shaped bodies as shown in FIG. 2 (c). May be.
Further, as shown in FIG. 2D, the end of the thrust bearing 52 can be easily chamfered by being chamfered.

このように、スラスト軸受５２を弾性体である樹脂で構成することで、加工精度をそれほど高くしなくとも、スラスト軸受５２をスラスト支持体５４の溝５６にぴったり嵌合させることができる。また、スラスト軸受の取付ボルトによる固定が不要となり、樹脂からなるスラスト軸受５２を溝５６に嵌め込むだけの作業でよいので、組立の手間と時間を減らすことができる。   In this way, by configuring the thrust bearing 52 with a resin which is an elastic body, the thrust bearing 52 can be fitted into the groove 56 of the thrust support 54 without increasing the processing accuracy. Further, it is not necessary to fix the thrust bearing with mounting bolts, and it is only necessary to fit the thrust bearing 52 made of resin into the groove 56, so that it is possible to reduce the labor and time of assembly.

また、このスラスト軸受５２は、棒状の樹脂材料を適当な長さに切ることにより、簡便に、各種サイズに対応することができる。
なお、長辺１５ｍｍ、短辺９ｍｍの矩形の断面のガラス入りテフロンからなる棒状体を図２（ｂ）のような形状に曲げて、内径２９５ｍｍのスラスト軸受を製作したところ、曲げによる割れの発生はなく、使用温度１３０℃でも耐久性のあることが確認された。
また、この棒状体の断面形状は、図２（ａ）のように必ずしも縦に長い矩形に限るものではなく、横に長い断面の矩形であってもよい。 Further, the thrust bearing 52 can be easily adapted to various sizes by cutting a rod-shaped resin material into an appropriate length.
When a rod-shaped body made of glass-filled Teflon with a long side of 15 mm and a short side of 9 mm is bent into a shape as shown in FIG. 2B, a thrust bearing with an inner diameter of 295 mm is produced. No durability was found even at a use temperature of 130 ° C.
Moreover, the cross-sectional shape of this rod-shaped body is not necessarily limited to a vertically long rectangle as shown in FIG. 2A, and may be a rectangle having a horizontally long cross section.

ここで、一方向クラッチ１０は、通常、水平方向に取付けられるので、スラスト軸受５２及びスラスト支持体５４からなるスラスト部材５０には大きなスラスト荷重は作用しない場合が殆どであるが、水平軸に対して傾斜して取付られる可能性も考慮し、スラスト部材５０は外輪３０の重量を支持することが可能な強度を有することが好ましい。
なお、この外輪３０の重量に耐えられる程度の強度は、樹脂材料で十分に得られる強度である。 Here, since the one-way clutch 10 is normally mounted in the horizontal direction, a large thrust load does not act on the thrust member 50 composed of the thrust bearing 52 and the thrust support body 54 in most cases. The thrust member 50 preferably has a strength capable of supporting the weight of the outer ring 30 in consideration of the possibility of being inclined and attached.
It should be noted that the strength enough to withstand the weight of the outer ring 30 is a strength sufficiently obtained with a resin material.

図１には、係合部材４０とローラケージ７０が別のケージ内に組み込まれた一方向クラッチ１０が示されているが、これに限るものではなく、例えば、ローラケージ７０と係合部材４０を同一ケージ内に組み込んだものであってもよい。
また、これまで係合部材４０をスプラグとして説明してきたが、本発明はこれに限るものでなく、係合部材４０がローラからなるものであってもよい。 Although FIG. 1 shows the one-way clutch 10 in which the engaging member 40 and the roller cage 70 are incorporated in different cages, the present invention is not limited to this. For example, the roller cage 70 and the engaging member 40 are included. May be incorporated in the same cage.
Although the engaging member 40 has been described as a sprag, the present invention is not limited to this, and the engaging member 40 may be a roller.

以上説明したように、本発明によれば、スラスト軸受が弾性体である樹脂からなるので、加工精度を高くしなくとも、スラスト軸受をスラスト支持体の溝にぴったり嵌合させることができる。また、スラスト軸受を取付ボルトによる固定が不要となり、樹脂からなるスラスト軸受を溝に嵌め込むだけの作業でよいので、組立の手間と時間を減らすことができるという効果を奏する。   As described above, according to the present invention, since the thrust bearing is made of an elastic resin, the thrust bearing can be fitted into the groove of the thrust support body without increasing the processing accuracy. In addition, the thrust bearing need not be fixed with mounting bolts, and only the work of fitting the thrust bearing made of resin into the groove is required, so that it is possible to reduce the time and labor of assembly.
