Description

この発明は、各種産業機械や車両等において動力伝達用に用いられる固定式等速ジョイント用外輪、特に防振型外輪に関するものである。   The present invention relates to an outer ring for a fixed type constant velocity joint used for power transmission in various industrial machines and vehicles, and more particularly to a vibration-proof outer ring.

等速ジョイント用の防振型外輪として従来から知られているものは、外側外輪と内側外輪が所要のすき間をおいて相互に嵌合され、内側外輪が複数のトラック溝を有し、そのトラック溝相互間の内側外輪の外面側の嵌合面とこれに対向した外側外輪の内面側の嵌合面において外側外輪に軸方向の干渉突条が形成され、前記内側外輪にその干渉突条に嵌り合う溝が設けられ、前記外側外輪と内側外輪のすき間に防振材としての防振ゴムが加硫接着等により固着された構成である（特許文献１）。   Conventionally known anti-vibration outer rings for constant velocity joints include an outer outer ring and an inner outer ring that are fitted together with a required gap, and the inner outer ring has a plurality of track grooves, and the track Interference protrusions in the axial direction are formed on the outer outer ring on the outer surface of the inner outer ring between the grooves and the inner surface of the outer outer ring facing the inner outer ring, and the inner outer ring has an interference protrusion on the inner outer ring. A fitting groove is provided, and an anti-vibration rubber as an anti-vibration material is fixed by vulcanization adhesion or the like between the outer outer ring and the inner outer ring (Patent Document 1).

前記の防振ゴムによって外側外輪と内側外輪間に伝播する振動が吸収される。また前記干渉突条と溝とが周方向に係合することにより外側外輪と内側外輪の周方向への相対移動が規制され、これにより防振ゴムの過大変形が防止される。
特許第３０５３６３６号公報 The vibrations propagating between the outer outer ring and the inner outer ring are absorbed by the anti-vibration rubber. Further, the interference protrusion and the groove are engaged in the circumferential direction, so that the relative movement of the outer outer ring and the inner outer ring in the circumferential direction is restricted, thereby preventing excessive deformation of the vibration isolating rubber.
Japanese Patent No. 3053636

前記のように防振ゴムは干渉突条と溝との干渉によって過大な変形が防止されるが、ジョイントに間断なく微小振動が加えられると、防振ゴムに作用する繰り返し荷重によりゴム組織に発熱が生じ、その発熱に伴ってジョイント内部の内圧が上昇する等の問題があった。また、防振ゴムを外側外輪と内側外輪のすき間に加硫接着等により固定させる作業が必要であり、作業性を阻害する問題もあった。   As mentioned above, the anti-vibration rubber is prevented from excessive deformation due to the interference between the interference protrusion and the groove. There was a problem that the internal pressure inside the joint increased with the heat generation. In addition, it is necessary to fix the anti-vibration rubber between the outer outer ring and the inner outer ring by vulcanization adhesion or the like, and there is a problem of impeding workability.

そこで、この発明は防振型の固定式等速ジョイント用外輪において防振ゴムによる発熱を防止し、ジョイントの内部温度の上昇を防ぐことを課題とする。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent heat generation due to vibration isolating rubber in an anti-vibration type fixed constant velocity joint outer ring and prevent an increase in internal temperature of the joint.

前記の課題を解決するために、この発明は、図１から図３に示したように、外側外輪１と内側外輪２が所要のすき間９をおいて相互に嵌合され、前記両外輪１、２のいずれか一方の嵌合面３に軸方向の干渉突条４、他方の嵌合面５に前記干渉突条４に係合する溝６が設けられ、前記嵌合面３、５間に防振材が介在され、該防振材を介して外側外輪１と内側外輪２が一体化され、前記内側外輪２の内面に鋼球２１の転動溝１４が複数形成された固定式等速ジョイント用外輪において、上記防振材が板ばね７により形成され、該板ばね７に前記嵌合面３、５間の相対向の間で圧縮される弾性変形部１２が設けられた構成としたものである。   In order to solve the above-described problem, the present invention is configured so that the outer outer ring 1 and the inner outer ring 2 are fitted to each other with a required gap 9 as shown in FIGS. 2 is provided with a groove 6 that engages with the interference protrusion 4, and the other engagement surface 5 is provided with a groove 6 that engages with the interference protrusion 4. An anti-vibration material is interposed, the outer outer ring 1 and the inner outer ring 2 are integrated via the anti-vibration material, and a plurality of rolling grooves 14 of steel balls 21 are formed on the inner surface of the inner outer ring 2. In the outer ring for joints, the vibration isolating material is formed by a leaf spring 7, and the leaf spring 7 is provided with an elastic deformation portion 12 that is compressed between the facing surfaces of the fitting surfaces 3 and 5. Is.

前記の板ばね７としては、例えば、図３（ａ）（ｂ）に示したように、前記干渉突条４に跨った湾曲部１１と、その湾曲部１１の両側部を該湾曲部１１に沿って外側に折り返すことによって弾性変形部１２が設けられたものを用いることができる。また図４（ａ）に示したような板ばね７の全体に波付けを施し、その波付けによって弾性変形部１２’が設けられる場合もある。   As the leaf spring 7, for example, as shown in FIGS. 3A and 3B, the bending portion 11 straddling the interference protrusion 4 and both side portions of the bending portion 11 are connected to the bending portion 11. It is possible to use one provided with the elastic deformation portion 12 by being folded outward along the line. Further, there is a case where the entire leaf spring 7 as shown in FIG. 4A is corrugated and the elastic deformation portion 12 ′ is provided by the corrugation.

前記構成の固定式等速ジョイント用外輪８において、板ばね７は干渉突条４に跨ることによって周方向の移動が規制される。またその折り返しや波付けによって形成された弾性変形部１２、１２’が嵌合面３、５の間に圧縮代をもって介在されるので、外側外輪１と内側外輪２の間に伝播する振動が吸収され、また、弾性変形部１２、１２’の摩擦により外側外輪１と内側外輪２との一体化が図られる。   In the fixed constant velocity joint outer ring 8 having the above-described configuration, the leaf spring 7 is restricted from moving in the circumferential direction by straddling the interference protrusion 4. Further, since the elastically deforming portions 12 and 12 ′ formed by the folding and corrugation are interposed between the fitting surfaces 3 and 5 with a compression allowance, vibration propagating between the outer outer ring 1 and the inner outer ring 2 is absorbed. In addition, the outer outer ring 1 and the inner outer ring 2 can be integrated by the friction of the elastically deforming portions 12 and 12 '.

以上のように、この発明の固定式等速ジョイント用外輪は、相互に嵌合された外側外輪と内側外輪の嵌合面間に介在される防振材として板ばねを使用し、その板ばねに前記嵌合面間で圧縮される弾性変形部を設けたことにより、その板ばねによって外側外輪と内側外輪の間に伝播する振動が吸収されるとともに、外側外輪と内側外輪との一体化が図られる。また、前記板ばねに振動が繰り返し負荷されても板ばねが発熱することはないので、ジョイント内部の内圧上昇も防ぐことができる。   As described above, the fixed type constant velocity joint outer ring according to the present invention uses a leaf spring as a vibration isolating material interposed between the fitting surfaces of the outer outer ring and the inner outer ring fitted to each other. By providing an elastically deforming portion that is compressed between the fitting surfaces, vibrations transmitted between the outer outer ring and the inner outer ring are absorbed by the leaf spring, and the outer outer ring and the inner outer ring are integrated. Figured. Further, even if vibration is repeatedly applied to the leaf spring, the leaf spring does not generate heat, so that an increase in internal pressure inside the joint can be prevented.

以下、添付図面に基づいてこの発明の実施例を説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１から図３に示した実施例１の固定式等速ジョイント用外輪８は、外側外輪１、内側外輪２及び防振材としての板ばね７により構成される。外側外輪１は、一端開放のカップ形をなし、閉塞側の端面中央に外輪軸１９が設けられる。外側外輪１の内面、即ち嵌合面３に所要の嵌合すき間９をおいて内側外輪２が嵌合される。   An outer ring 8 for a fixed type constant velocity joint according to the first embodiment shown in FIGS. 1 to 3 includes an outer outer ring 1, an inner outer ring 2, and a leaf spring 7 as a vibration isolating material. The outer outer ring 1 has a cup shape with one end open, and an outer ring shaft 19 is provided in the center of the end face on the closing side. The inner outer ring 2 is fitted to the inner surface of the outer outer ring 1, that is, the fitting surface 3 with a required fitting gap 9.

外側外輪１の前記嵌合面３には周方向６等分位置に軸方向の干渉突条４が設けられる。この干渉突条４の断面形状は図に示したように緩やかな山形をなす。内側外輪２は、その内面に等間隔をおいて内輪２５（図２参照）に組み込まれた鋼球２１の軸方向に湾曲した転動溝１４が形成され、各転動溝１４の相互間に溝間壁面２２が形成される。   An axial interference protrusion 4 is provided on the fitting surface 3 of the outer outer ring 1 at a position equally divided by six in the circumferential direction. The cross-sectional shape of the interference protrusion 4 is a gentle mountain shape as shown in the figure. The inner outer ring 2 is formed with rolling grooves 14 curved in the axial direction of steel balls 21 incorporated in the inner ring 25 (see FIG. 2) at equal intervals on the inner surface, and between the rolling grooves 14. An inter-groove wall surface 22 is formed.

前記内輪２５は内輪軸２３の先端部に嵌合固定される。内輪２５は、転動溝１４を転動する鋼球２１の作用により外輪軸１９に対して内輪軸２３を屈曲させる固定式等速ジョイントの作用を行う。   The inner ring 25 is fitted and fixed to the tip of the inner ring shaft 23. The inner ring 25 acts as a fixed constant velocity joint that bends the inner ring shaft 23 with respect to the outer ring shaft 19 by the action of the steel ball 21 that rolls in the rolling groove 14.

内側外輪２は転動溝１４の溝底部分で最も薄肉となり、また溝間壁面２２の部分で最も厚肉となる。その厚肉の部分において前記干渉突条４に対向した溝６が設けられる。   The inner outer ring 2 is the thinnest at the groove bottom portion of the rolling groove 14 and the thickest at the portion of the wall surface 22 between the grooves. A groove 6 facing the interference protrusion 4 is provided in the thick portion.

前記の内側外輪２を外側外輪１の内側に嵌合させる際、外側外輪１の干渉突条４の部分に板ばね７を予め仮り止めしておき、その後内側外輪２を圧入させる。内側外輪２は板ばね７を圧縮させつつ圧入され、板ばね７以外の部分では両方の嵌合面３、５間に一定のすき間９が生じる。また、外側外輪１の干渉突条４が、板ばね７を介して溝６に嵌入され、その嵌入により外側外輪１と内側外輪２の相対的な回転が規制される。   When the inner outer ring 2 is fitted inside the outer outer ring 1, the leaf spring 7 is temporarily secured to the interference protrusion 4 of the outer outer ring 1, and then the inner outer ring 2 is press-fitted. The inner outer ring 2 is press-fitted while compressing the leaf spring 7, and a fixed gap 9 is formed between both the fitting surfaces 3 and 5 at portions other than the leaf spring 7. In addition, the interference protrusion 4 of the outer outer ring 1 is inserted into the groove 6 via the leaf spring 7, and the relative rotation between the outer outer ring 1 and the inner outer ring 2 is restricted by the insertion.

前記の板ばね７は、図３（ａ）（ｂ）に示したように、前記の干渉突条４に跨った湾曲部１１と、その湾曲部１１の両側部において該湾曲部１１に沿って折り返して形成された弾性変形部１２とからなる。その弾性変形部１２が干渉突条４と溝６の間において所要の圧縮代をもって介在される。   As shown in FIGS. 3A and 3B, the leaf spring 7 includes a curved portion 11 straddling the interference protrusion 4 and along the curved portion 11 on both sides of the curved portion 11. It consists of the elastic deformation part 12 formed by folding. The elastic deformation portion 12 is interposed between the interference protrusion 4 and the groove 6 with a required compression allowance.

実施例１の固定式等速ジョイント用の外輪８は以上のようなものであり、図２に示したように、内側外輪２に内輪２５が嵌合され、その鋼球２１が転動溝１４に嵌められるとともに、内輪軸２３と外側外輪１との間にブーツ２４が装着され、固定式等速ジョイントとして使用に供される。   The outer ring 8 for the fixed type constant velocity joint of the first embodiment is as described above. As shown in FIG. 2, the inner ring 25 is fitted to the inner outer ring 2, and the steel ball 21 is rolled into the rolling groove 14. And a boot 24 is mounted between the inner ring shaft 23 and the outer outer ring 1 for use as a fixed constant velocity joint.

使用中における外側外輪１及び内側外輪２の相対回転又は軸方向への相対移動、板ばね
７自体の周方向への移動は、板ばね７の弾性変形部１２の圧縮変形による摩擦や干渉突条４と溝６との干渉などにより防止される。また、外側外輪１及び内側外輪２間に伝播する振動は、弾性変形部１２の微小な弾性変形によって吸収される。 The relative rotation or axial movement of the outer outer ring 1 and the inner outer ring 2 during use, and the movement of the leaf spring 7 itself in the circumferential direction are caused by friction caused by compressive deformation of the elastic deformation portion 12 of the leaf spring 7 and interference protrusions. 4 and the groove 6 prevent this. Further, the vibration propagating between the outer outer ring 1 and the inner outer ring 2 is absorbed by minute elastic deformation of the elastic deformation portion 12.

図４（ａ）から（ｃ）は、上述した実施例１の一部を変更した例を示す。図４（ａ）は板ばね７を変形した例である。即ち、この場合の板ばね７は、全体に軸方向の山と谷が並んだ細かい波付けが施され、その波付けにより弾性変形部１２’が形成されたものであり、干渉突条４と溝６間の湾曲したすき間９に沿って湾曲状態に所要の圧縮代をもって介在される。その圧縮変形による摩擦等により外側外輪１と内側外輪２の一体化が図られる。また、外側外輪１及び内側外輪２間に伝播する振動は、弾性変形部１２’の微小な弾性変
形により吸収される。 FIGS. 4A to 4C show an example in which a part of the first embodiment is changed. FIG. 4A shows an example in which the leaf spring 7 is modified. In other words, the leaf spring 7 in this case is subjected to fine corrugation in which axial peaks and valleys are lined up as a whole, and an elastically deforming portion 12 ′ is formed by the corrugation. A curved space 9 between the grooves 6 is interposed in the curved state with a required compression allowance. The outer outer ring 1 and the inner outer ring 2 are integrated by friction or the like due to the compression deformation. Further, the vibration propagating between the outer outer ring 1 and the inner outer ring 2 is absorbed by minute elastic deformation of the elastic deformation portion 12 ′.

図４（ｂ）（ｃ）は、干渉突条４と溝６の関係が図３の場合とは逆に、干渉突条４が内側外輪２の嵌合面５に、また溝６が外側外輪１の嵌合面３にそれぞれ形成された場合である。板ばね７は、図４（ｂ）の場合は折り返しによって弾性変形部１２が形成され、同図（ｃ）の場合は、同図（ａ）の場合と同様に全体に形成された細かい波付けによって弾性変形部１２’が形成されたものである。   4 (b) and 4 (c), the relationship between the interference protrusion 4 and the groove 6 is opposite to that in FIG. 3, the interference protrusion 4 is on the fitting surface 5 of the inner outer ring 2, and the groove 6 is on the outer outer ring. 1 is formed on each of the fitting surfaces 3. In the case of FIG. 4B, the leaf spring 7 is formed with an elastically deforming portion 12 by folding, and in the case of FIG. 4C, the fine corrugation formed on the whole as in the case of FIG. Thus, an elastically deformable portion 12 ′ is formed.

次に、図５（ａ）（ｂ）に示した実施例２は、外側外輪１と内側外輪２及び防振材によって構成された固定式等速ジョイントの外輪８である点では前記実施例１の場合と同様であるが、防振材として外側外輪１と内側外輪２の間に介在された板ばね１５の形状が相違している。即ち、この場合の板ばね１５は、隣接した二つの干渉突条４間に介在されるものであり、内側外輪２の外周面に沿った湾曲部２６が形成され、その湾曲部２６の両側部にそれぞれ溝６の壁面に沿って屈曲された屈曲部１６が形成される。さらにその屈曲部１６の先端側縁を干渉突条４に沿って折り返すことによって弾性変形部１８が形成されている。   Next, the second embodiment shown in FIGS. 5A and 5B is the first embodiment in that it is the outer ring 8 of the fixed type constant velocity joint constituted by the outer outer ring 1, the inner outer ring 2 and the vibration isolating material. However, the shape of the leaf spring 15 interposed between the outer outer ring 1 and the inner outer ring 2 as a vibration isolating material is different. That is, the leaf spring 15 in this case is interposed between two adjacent interference protrusions 4, and a curved portion 26 is formed along the outer peripheral surface of the inner outer ring 2, and both side portions of the curved portion 26 are formed. Each of the bent portions 16 is bent along the wall surface of the groove 6. Further, the elastic deformation portion 18 is formed by folding back the front edge of the bent portion 16 along the interference protrusion 4.

板ばね１５は、両側の干渉突条４、４の間に介在されるので周方向への移動が規制される。また、実施例１の場合と同様に、弾性変形部１８が圧縮代をもって干渉突条４と溝６間に介在されるので、外側外輪１と内側外輪２との一体化が図られ、また外側外輪１と内側外輪２間に伝播する振動が弾性変形部１８により吸収される。   Since the leaf | plate spring 15 is interposed between the interference protrusions 4 and 4 on both sides, the movement to the circumferential direction is controlled. Further, as in the case of the first embodiment, since the elastic deformation portion 18 is interposed between the interference protrusion 4 and the groove 6 with a compression allowance, the outer outer ring 1 and the inner outer ring 2 are integrated, and the outer side Vibration propagating between the outer ring 1 and the inner outer ring 2 is absorbed by the elastic deformation portion 18.

図６（ａ）（ｂ）は前記板ばね１５を変形した例であり、この場合の板ばね１５も前記と同様の湾曲部２６とその両端に屈曲部１６が形成されたものであるが、弾性変形部１８’は板ばね１５の全体にわたり軸方向に沿って並んだ細かい波付けにより形成される。   6 (a) and 6 (b) are examples in which the leaf spring 15 is deformed, and the leaf spring 15 in this case also has a curved portion 26 similar to the above and bent portions 16 formed at both ends thereof. The elastically deformable portion 18 ′ is formed by fine corrugations arranged along the axial direction over the entire plate spring 15.

図７（ａ）は、図５の変形例であり、また図７（ｂ）は図６の変形例である。いずれの場合も干渉突条４と溝６を逆に、即ち、干渉突条４を内側外輪２側に、溝６を外側外輪１側に設けたものであり、その位置関係に応じて屈曲部１６を外向きに形成している。図７（ａ）の場合は、屈曲部１６の先端側縁を折り返して弾性変形部１８が形成され、また同図（ｂ）の場合は細かい波付けによって弾性変形部１８’が形成される。   FIG. 7A is a modification of FIG. 5, and FIG. 7B is a modification of FIG. In any case, the interference protrusion 4 and the groove 6 are reversed, that is, the interference protrusion 4 is provided on the inner outer ring 2 side, and the groove 6 is provided on the outer outer ring 1 side. 16 is formed outward. In the case of FIG. 7 (a), the elastic deformation portion 18 is formed by folding the front end side edge of the bending portion 16, and in the case of FIG. 7 (b), the elastic deformation portion 18 'is formed by fine corrugation.

図８（ａ）（ｂ）に示した実施例３は、前述の図６の場合において波付きの板ばね１５を転動溝１４ごとに独立に設ける構成に代えて、１枚の波付板ばね１５を円筒状に形成したものである。図示のように、１箇所において軸方向の切り離し部２８を形成すると全体の変形量が増大する。図８（ｃ）は干渉突条４と溝６の位置を逆にした場合である。   The third embodiment shown in FIGS. 8A and 8B is a single corrugated plate in place of the configuration in which the corrugated leaf spring 15 is provided independently for each rolling groove 14 in the case of FIG. The spring 15 is formed in a cylindrical shape. As shown in the drawing, when the axial cut-off portion 28 is formed at one location, the overall deformation amount increases. FIG. 8C shows the case where the positions of the interference protrusion 4 and the groove 6 are reversed.

図９（ａ）（ｂ）に示した実施例４は、内側外輪２が６個の独立した内側外輪片２ａからなり、各内側外輪片２ａの内面に１本の転動溝１４が設けられる。各内側外側片２ａ、前記外側外輪１の干渉突条４相互間に形成された凹部２７に所要のすき間９をおいて嵌合され、そのすき間９に板ばね１５が介在される。板ばね１５は、先に図５（ａ）（ｂ）に示したものと同様であり、湾曲部２６の両側部に内向きに形成された屈曲部１６、さらにその屈曲部１６の先端側縁を外向きに折り返すことによって弾性変形部１８が形成されている。   In Embodiment 4 shown in FIGS. 9A and 9B, the inner outer ring 2 is composed of six independent inner outer ring pieces 2a, and one rolling groove 14 is provided on the inner surface of each inner outer ring piece 2a. . Each inner outer piece 2 a and a recess 27 formed between the interference protrusions 4 of the outer outer ring 1 are fitted with a required gap 9, and a leaf spring 15 is interposed in the gap 9. The leaf spring 15 is the same as that shown in FIGS. 5 (a) and 5 (b). The bent portion 16 is formed inwardly on both sides of the bending portion 26, and the leading edge of the bent portion 16 is also provided. The elastic deformation part 18 is formed by folding outward.

板ばね１５はその湾曲部２６と両側の屈曲部１６、１６によって各内側外輪片２ａの外面をカバーし、各弾性変形部１８、１８がそれぞれ干渉突条４、４の側面に押し当てられる。各内側外輪片２ａは弾性変形部１８、１８の弾性によって外側外輪１の凹部２７に保持される。   The leaf spring 15 covers the outer surface of each inner outer ring piece 2a by the curved portion 26 and the bent portions 16 and 16 on both sides, and the elastic deformation portions 18 and 18 are pressed against the side surfaces of the interference protrusions 4 and 4, respectively. Each inner outer ring piece 2 a is held in the concave portion 27 of the outer outer ring 1 by the elasticity of the elastic deformation portions 18 and 18.

図１０は図９の場合の板ばね１５の全体に細かい波付けが施されたものであり、その波付けによって弾性変形部１８’が形成される。     FIG. 10 shows the whole leaf spring 15 in the case of FIG. 9 which is finely corrugated, and an elastic deformation portion 18 ′ is formed by the corrugation.
