Description

本発明は、Vベルト式自動変速装置において、ボス軸に対してプーリフェイスを簡単且つ迅速に装着することができ、その接合状態を極めて強固にすることができるVベルト式自動変速装置のプーリに関する。   The present invention relates to a pulley for a V-belt type automatic transmission in which a pulley face can be easily and quickly mounted on a boss shaft and the joining state thereof can be made extremely strong in a V-belt type automatic transmission. .

Vベルト式自動変速装置のプーリの製造において、特に従動側プーリでは、ドリブンフェイスとボスとを接合するのに、レーザー溶接、プラズマ溶接などによって一体化することが特許文献1に開示されている。さらにプーリの背面側に油室の一部を構成するシリンダを、前記可動側プーリの背面側にカジメにより固定することが特許文献2に開示されている。
特開平10−103438号 特開平9−329208号
In manufacturing a pulley for a V-belt type automatic transmission, Patent Document 1 discloses that a driven pulley and a boss are integrated by laser welding, plasma welding, or the like, particularly in a driven pulley. Further, Patent Document 2 discloses that a cylinder constituting a part of the oil chamber is fixed to the back side of the pulley by caulking on the back side of the movable pulley.
JP 10-103438 A JP-A-9-329208

まず、特許文献1では、前記ドリブンフェイスとボスとを溶接により接合一体化しプーリを製造する場合、溶接作業による熱影響によって生じる歪を避けたり、溶接部の応力集中を避けて荷重に対する耐久性の向上を図る為に、レーザー溶接という特殊な溶接設備が必要となる。そのために、設備を構築しなければならないか、又はそのような設備を備えた製造工場でなければ、上記プーリは製造することができない。   First, in Patent Document 1, when the driven face and the boss are joined and integrated by welding to produce a pulley, distortion caused by the thermal effect due to welding work is avoided, stress concentration at the weld is avoided, and durability against load is avoided. In order to improve, special welding equipment called laser welding is required. For this purpose, the pulleys cannot be manufactured unless facilities must be constructed or a manufacturing plant equipped with such facilities.

また、特許文献2では、カシメ手段によるものが開示されている。この特許文献2では、可動側プーリの背面側の環状フランジにシリンダを圧入する方法が開示されている。これについては、可動側プーリの背面側の環状溝にシリンダ端部全体をカシメて、可動側プーリと油室の一部を構成するものであり、シリンダは密封して固定されるものである。この可動側プーリの背面側とシリンダとのカシメによる接合であるが、この接合手段はプーリとの回転力を従動軸へ伝達するボスとの接合構造に対しては好適ではない。   Patent Document 2 discloses a method using caulking means. In Patent Document 2, a method of press-fitting a cylinder into an annular flange on the back side of a movable pulley is disclosed. About this, the whole cylinder edge part is crimped to the annular groove of the back side of a movable pulley, and a movable pulley and a part of oil chamber are comprised, and a cylinder is sealed and fixed. This joining is performed by caulking the back side of the movable pulley and the cylinder, but this joining means is not suitable for a joining structure with a boss that transmits the rotational force of the pulley to the driven shaft.

なぜならば、従動側の可動プーリのボスとプーリフェイスにおいて、単にボスに環状溝を設けてプーリフェイスの内方端部全体をカシメにより固定しても、その固定箇所で円周方向に対する滑りが発生したり、軸方向の摺動荷重に対する座屈が発生したりして、プーリフェイスとボスとの結合固定を安定させることが極めて困難となるからである。   This is because even if the boss and pulley face of the movable pulley on the driven side are simply provided with an annular groove in the boss and the entire inner end of the pulley face is fixed by caulking, slipping in the circumferential direction occurs at the fixed location. This is because it becomes extremely difficult to stabilize the coupling and fixing of the pulley face and the boss due to the occurrence of buckling with respect to the sliding load in the axial direction.

即ち、従動側プーリにおける可動プーリのボスとプーリフェイスとを単にカシメにより固定しても、耐久性のある実用的なプーリにすることが困難である。そこで、本発明が解決しようとする目的(技術的課題)は、従動側プーリにおける可動プーリのボスとプーリフェイスとを特殊な溶接で固定することなく、両部材を塑性加工(圧入とカシメ)によって容易に結合固定し、且つ、実用的に使用できるVベルト式自動変速装置のプーリを提供するものである。   That is, even if the boss and the pulley face of the movable pulley in the driven pulley are simply fixed by caulking, it is difficult to obtain a durable and practical pulley. Therefore, an object (technical problem) to be solved by the present invention is to fix both the members by plastic working (press fitting and caulking) without fixing the boss of the movable pulley and the pulley face in the driven pulley by special welding. It is an object of the present invention to provide a pulley for a V-belt type automatic transmission that can be easily coupled and fixed and can be used practically.

そこで、発明者は、上記課題を解決すべく、鋭意,研究を重ねた結果、請求項1の発明を、ボス軸部と、該ボス軸部の軸方向一端側に形成された大径円筒部とからなり、前記ボス軸部と大径円筒部との間は段差面部とし、前記段差面部には直径方向に延在するように鍔状部が形成され、前記大径円筒部の外周側面にはその軸方向に沿って溝状凹み部が溝形状又は筋形状として形成され、前記鍔状部には、前記溝状凹み部の形成された位置に対応する位置に切欠き部が形成されてなるボス部材と、プーリフェイス部の直径中心に円筒接合部が形成された可動プーリフェイスとからなり、前記円筒接合部は前記大径円筒部に挿入されると共に前記溝状凹み部の形状に沿って前記円筒接合部の肉部はカシメにて固定されてなるVベルト式自動変速装置のプーリとしたことにより、上記課題を解決したものである。   In view of the above, the inventors have intensively and researched to solve the above-described problems. As a result, the invention of claim 1 is obtained by combining the boss shaft portion and the large-diameter cylindrical portion formed on one end side in the axial direction of the boss shaft portion. A stepped surface portion is formed between the boss shaft portion and the large diameter cylindrical portion, and a hook-shaped portion is formed on the stepped surface portion so as to extend in the diameter direction. A groove-like recess is formed as a groove shape or a streak shape along the axial direction, and the notch is formed in the collar-like portion at a position corresponding to the position where the groove-like recess is formed. And a movable pulley face having a cylindrical joint formed at the center of the diameter of the pulley face portion. The cylindrical joint portion is inserted into the large-diameter cylindrical portion and follows the shape of the groove-shaped recess portion. V-belt automatic transmission device in which the cylindrical portion is fixed by caulking By the pulley was one in which the above-mentioned problems are eliminated.

請求項2の発明を、前述の構成において、前記溝状凹み部は、前記大径円筒部の段差面部側から軸方向の略中央の位置までのみ形成されてなるVベルト式自動変速装置のプーリとしたことにより、上記課題を解決したものである。請求項3の発明を、前述の構成において、前記溝状凹み部は、前記段差面部側から軸方向端部側に向かって次第に浅くなるように形成されてなるVベルト式自動変速装置のプーリとしたことにより、上記課題を解決した。   According to a second aspect of the invention, there is provided a pulley for a V-belt type automatic transmission in which the groove-like recessed portion is formed only from the stepped surface side of the large-diameter cylindrical portion to a substantially central position in the axial direction. Thus, the above-mentioned problems are solved. According to a third aspect of the present invention, there is provided a pulley of a V-belt type automatic transmission in which the groove-shaped recess is formed so as to gradually become shallower from the stepped surface portion side toward the axial end portion side. As a result, the above problems were solved.

請求項4の発明を、前述の構成において、前記溝状凹み部の底面の軸方向断面形状は、弧状に形成されてなるVベルト式自動変速装置のプーリとしたことにより、上記課題を解決した。   According to a fourth aspect of the present invention, in the above-described configuration, the axial cross-sectional shape of the bottom surface of the groove-shaped recess is an arc-shaped pulley of a V-belt type automatic transmission, thereby solving the above problem. .

請求項1の発明によって、ボス部材の大径円筒部と、可動プーリフェイスの円筒接合部とを接合し、前記大径円筒部の溝状凹み部箇所において、円筒接合部にはカシメによる塑性変形部が形成されることによりボス部材と可動プーリフェイスとを極めて強固に固着することができる。   According to the invention of claim 1, the large-diameter cylindrical portion of the boss member and the cylindrical joint portion of the movable pulley face are joined, and the cylindrical joint portion is plastically deformed by caulking at the groove-like recess portion of the large-diameter cylindrical portion. By forming the portion, the boss member and the movable pulley face can be fixed extremely firmly.

特に、カシメによる塑性変形部は、前記可動プーリフェイスの回転方向において、該可動プーリフェイスの円筒接合部とボス部材の大径円筒部との相互の回り止としての役目をなすものである。また、ボス部材と可動プーリフェイスとをカシメによる塑性加工によって容易に結合固定することが出来るので、ボス部材と可動プーリフェイスとを組付けた後の結合固定の精度が向上し、ボス部材の回転軸線(軸方向)に対して可動プーリフェイスの回転振れ(倒れ)を容易に抑制することが出来る。   In particular, the plastic deformation portion due to caulking serves as a mutual detent between the cylindrical joint portion of the movable pulley face and the large diameter cylindrical portion of the boss member in the rotational direction of the movable pulley face. In addition, since the boss member and the movable pulley face can be easily coupled and fixed by plastic working by caulking, the accuracy of coupling and fixing after the boss member and movable pulley face are assembled is improved, and the boss member is rotated. It is possible to easily suppress rotational deflection (falling) of the movable pulley face with respect to the axis (axial direction).

さらに、請求項1の発明では、ボス部材と可動側プーリフェースとを接合して組付けを行うときに、前記ボス部材の大径円筒部に、前記可動プーリフェイスを装着する場合の円筒接合部のボス軸部に対する位置決め用の役目をなすことができるものである。また、前記鍔部によって、Vベルトによる圧力がプーリフェイスの表面側の荷重としてかかり、大径円筒部から円筒接合部が抜け出そうとすることに対する外れ止め又はストッパとしての役目をなすことができ、極めて強固な構造のものにすることができる。   Further, according to the first aspect of the present invention, when the boss member and the movable pulley face are joined and assembled, the cylindrical joint portion when the movable pulley face is attached to the large diameter cylindrical portion of the boss member. It can serve for positioning with respect to the boss shaft portion. In addition, by the flange portion, the pressure by the V belt is applied as a load on the surface side of the pulley face, and it can serve as a stopper or stopper against the cylindrical joint portion coming out of the large diameter cylindrical portion, An extremely strong structure can be obtained.

請求項2の発明によって、前記溝状凹み部は、前記大径円筒部の段差面部側から軸方向の略中央の位置までのみ形成されることにより、溝状凹み部における大径円筒部と円筒接合部とのカシメによる塑性変形部は、大径円筒部の段差面部側付近にのみ形成されることとなる。よって、前記ボス部材から可動側プーリフェースが軸方向に抜け出そうとする外力がかかった場合に、前記塑性変形部と溝状凹み部とが軸方向における強固な抜止めとしての役目をなし、ボス部材に対する可動プーリフェイスの軸方向における接合強度を極めて強固なものにすることができる。   According to a second aspect of the present invention, the groove-shaped recess is formed only from the stepped surface portion side of the large-diameter cylindrical portion to a substantially central position in the axial direction, whereby the large-diameter cylindrical portion and the cylinder in the groove-shaped recess are formed. The plastically deformed portion by caulking with the joint portion is formed only in the vicinity of the stepped surface portion side of the large diameter cylindrical portion. Therefore, when an external force is applied to the movable pulley face in the axial direction from the boss member, the plastic deformation portion and the groove-shaped recess portion serve as a strong retaining in the axial direction, and the boss The joining strength in the axial direction of the movable pulley face with respect to the member can be made extremely strong.

このように、可動プーリフェイスの円筒接合部をVベルトとの非係合部側(背面側)において、カシメによる塑性変形部を深く形成することができ、ボス部材の円筒接合部との結合固定状態の抜け止めとなり、さらに強固な固定にできる。また、前記溝状凹み部は、軸方向において短くなり、カシメ領域も小さくすることができ、カシメ作業が簡単にできる。   In this way, the cylindrical joint portion of the movable pulley face can be deeply formed by caulking on the non-engagement portion side (back side) with the V-belt, and the boss member can be coupled and fixed to the cylindrical joint portion. The state is prevented from coming off and can be fixed more firmly. Further, the groove-like recess is shortened in the axial direction, the crimping area can be reduced, and the crimping operation can be simplified.

請求項3の発明によって、前記溝状凹み部は、前記段差面部側から軸方向端部側に向かって次第に浅くなるように形成されてなることにより、極めて強固な接合固定にすることができる。請求項4の発明によって、前記溝状凹み部の底面の軸方向断面形状は、弧状に形成されることにより、前記溝状凹み部の底面を直線状或いは平坦状に形成した場合に比較して、溝状凹み部の有効長さを長くすることができ、前記円筒接合部にカシメにより形成される塑性変形部との接触距離も長くなり、より一層、強固にボス部材と可動側プーリフェースとを接合することができる。   According to the third aspect of the present invention, the groove-shaped recess is formed so as to gradually become shallower from the stepped surface portion side toward the axial end portion side, whereby extremely strong bonding and fixing can be achieved. According to the invention of claim 4, the axial cross-sectional shape of the bottom surface of the groove-shaped recess is formed in an arc shape, so that the bottom surface of the groove-shaped recess is formed linearly or flatly. The effective length of the groove-like recess can be increased, the contact distance between the cylindrical joint and the plastic deformation portion formed by caulking is also increased, and the boss member and the movable pulley face Can be joined.

The pulley face portion 21 is formed in a flat conical shape, the convex side is the front side 211, and the opposite side is the back side 212. The cylindrical joint portion 22 is formed in a flat cylindrical shape, and is formed to protrude toward the back side 212 of the pulley face portion 21. The cylindrical joint portion 22 is a portion into which the large-diameter cylindrical portion 12 of the boss member 1 is inserted. The inner diameter of the through hole into which the large-diameter cylindrical portion 12 is inserted in the cylindrical joint portion 22 is even more suitable if the outer diameter of the large-diameter cylindrical portion 12 is accurate enough to fit a gap.

次に、前記ボス部材1の大径円筒部12と、前記可動プーリフェイス2の円筒接合部22との接合固定構造について述べる。まず、ボス部材1の段差面部14側から大径円筒部12の軸方向の略中央位置までにのみ溝状凹み部15が形成され、且つ前記段差面部14から大径円筒部12の軸方向端部に向かって次第に深さが浅くなるように形成された場合における大径円筒部12と円筒接合部22との接合構造は、以下のような構成となる。   Next, a joining and fixing structure between the large-diameter cylindrical portion 12 of the boss member 1 and the cylindrical joint portion 22 of the movable pulley face 2 will be described. First, the groove-like recess 15 is formed only from the step surface 14 side of the boss member 1 to the substantially central position in the axial direction of the large diameter cylindrical portion 12, and the axial end of the large diameter cylindrical portion 12 extends from the step surface 14. The joining structure of the large-diameter cylindrical portion 12 and the cylindrical joint portion 22 in the case where the depth gradually decreases toward the portion has the following configuration.

すなわち、前記大径円筒部12が前記円筒接合部22に挿入され、該円筒接合部22の外周側面で、且つ前記溝状凹み部15に対応する位置が凹むようにカシメが行われて凹み状の塑性変形され、この塑性変形により大径円筒部12と円筒接合部22との固定が行われる。このカシメによる凹み状の塑性変形部221は、前記円筒接合部22において前記段差面部14側寄りの箇所のみに形成されることになる〔図2(B),(C)参照〕。   That is, the large-diameter cylindrical portion 12 is inserted into the cylindrical joint portion 22, and caulking is performed so that the position corresponding to the groove-shaped recess portion 15 is recessed on the outer peripheral side surface of the cylindrical joint portion 22. The large-diameter cylindrical portion 12 and the cylindrical joint portion 22 are fixed by this plastic deformation. The concave plastic deformation portion 221 due to the caulking is formed only in the cylindrical joint portion 22 near the stepped surface portion 14 side (see FIGS. 2B and 2C).

上述したように、ボス軸部11と,該ボス軸部11の軸方向一端側に形成された大径円筒部12とからなり,前記ボス軸部11と大径円筒部12との間は段差面部14とし、前記大径円筒部12の外周側面にはその軸方向に沿って前記段差面部14側から軸方向端部側に向かって底面151が次第に浅くなる溝状凹み部15が形成されてなるボス部材1と、プーリフェイス部21の直径中心に円筒接合部22が形成された可動プーリフェイス2とからなり、前記円筒接合部22は前記大径円筒部12に挿入されると共に前記溝状凹み部15の形状に沿って前記円筒接合部22の肉部はカシメにて固定されたことにより、前記ボス部材1の大径円筒部12と、前記可動プーリフェイス2の円筒接合部22とを強固に接合することができると共に、強固な抜け止め構造とすることができる。そして、カシメによる凹み状の塑性変形部221は、前記大径円筒部12の軸方向端部側から前記円筒接合部22が抜け出すことが無いように強固に固定することができる。   As described above, the boss shaft portion 11 and the large-diameter cylindrical portion 12 formed on one end side in the axial direction of the boss shaft portion 11 include a step between the boss shaft portion 11 and the large-diameter cylindrical portion 12. A groove-like recess 15 is formed on the outer peripheral side surface of the large-diameter cylindrical portion 12 so that the bottom surface 151 gradually becomes shallower from the stepped surface portion 14 side toward the axial end portion along the axial direction. And a movable pulley face 2 in which a cylindrical joint 22 is formed at the center of the diameter of the pulley face 21. The cylindrical joint 22 is inserted into the large-diameter cylindrical part 12 and the groove shape. The flesh portion of the cylindrical joint portion 22 is fixed by caulking along the shape of the recess portion 15, so that the large-diameter cylindrical portion 12 of the boss member 1 and the cylindrical joint portion 22 of the movable pulley face 2 are connected. While being able to join firmly It can be a strong retaining structure. And the concave plastic deformation part 221 by caulking can be firmly fixed so that the said cylindrical joining part 22 does not slip out from the axial direction edge part side of the said large diameter cylindrical part 12. FIG.

すなわち、前記溝状凹み部15と円筒接合部22のカシメによる塑性変形部221とは、相互に楔状の作用が発生し、強固な抜け止めが行われる。さらに、前記溝状凹み部15が大径円筒部12の段差面部14側から大径円筒部12の軸端部側に亘って次第に浅くなるように形成される実施形態についても、同様に前記ボス部材1の大径円筒部12と、前記可動プーリフェイス2の円筒接合部22との間に強固な抜け止めが行われる。   That is, the groove-shaped recess 15 and the plastic deformation portion 221 due to the caulking of the cylindrical joint portion 22 generate a wedge-like action with each other, and a strong retaining is performed. Further, in the embodiment in which the groove-like recess portion 15 is formed so as to gradually become shallower from the stepped surface portion 14 side of the large-diameter cylindrical portion 12 to the shaft end portion side of the large-diameter cylindrical portion 12, similarly, the boss A strong retaining is performed between the large-diameter cylindrical portion 12 of the member 1 and the cylindrical joint portion 22 of the movable pulley face 2.

また、前述したように、前記溝状凹み部15は、前記大径円筒部12の段差面部14側から軸方向の略中央の位置までのみ形成されると共に該段差面部14側から軸方向端部側に向かって次第に浅くなるようにしたことにより、可動プーリフェイス2とボス部材1とを極めて強固に接合固定にすることができる。   Further, as described above, the groove-shaped recess 15 is formed only from the step surface portion 14 side of the large-diameter cylindrical portion 12 to a substantially central position in the axial direction and from the step surface portion 14 side to the axial end portion. By making it gradually shallower toward the side, the movable pulley face 2 and the boss member 1 can be bonded and fixed extremely firmly.

また、前記ボス部材1の大径円筒部12と、可動プーリフェイス2の円筒接合部22とは、圧入による接合状態とする実施形態も存在する。この実施形態では、前記ボス部材1の大径円筒部12には、前記溝状凹み部15の形成箇所以外では、前記大径円筒部12と前記円筒接合部22とは圧入で相互に押圧した状態となり、圧入による固定と、前述したカシメによる凹み状の塑性変形部221とが相乗的に作用し、極めて強固なる固着状態にすることができる。また、円筒接合部22の端部は、前記鍔状部17によって抜け出さないようにストッパとなって、可動プーリフェイス2のプーリフェイス部21がVベルト7によって押し拡げようとする荷重がかかっても、これに十分に耐え得るものにできる。   There is also an embodiment in which the large-diameter cylindrical portion 12 of the boss member 1 and the cylindrical joint portion 22 of the movable pulley face 2 are joined by press-fitting. In this embodiment, the large-diameter cylindrical portion 12 of the boss member 1 is pressed into the large-diameter cylindrical portion 12 and the cylindrical joint portion 22 by press-fitting to each other except where the groove-shaped recess portion 15 is formed. Thus, the fixing by press-fitting and the above-described dent-shaped plastic deformation portion 221 by caulking act synergistically, and an extremely strong fixed state can be obtained. Further, the end portion of the cylindrical joint portion 22 serves as a stopper so as not to come out by the hook-like portion 17, so that the pulley face portion 21 of the movable pulley face 2 is subjected to a load to be expanded by the V belt 7. , It can be tolerable enough.

次に、固定プーリ半体3は、固定側ボス部31と固定プーリフェイス32とから構成されている。この固定プーリ半体3についても、可動プーリ半体Aと同様に固定プーリフェイス32と固定側ボス部31とをカシメにて固定することは可能である。その固定側ボス部31は、前記可動プーリ半体Aのボス部材1の摺動孔部13に挿入され、前記可動プーリ半体Aが固定側ボス部31の軸方向に沿って摺動することができるようになっている。その固定側ボス部31の外周側面の所定箇所には、ガイドピン33が装着されている。   Next, the fixed pulley half 3 includes a fixed-side boss portion 31 and a fixed pulley face 32. Similarly to the movable pulley half A, the fixed pulley half 32 and the fixed-side boss 31 can be fixed by caulking. The fixed boss 31 is inserted into the sliding hole 13 of the boss member 1 of the movable pulley half A, and the movable pulley half A slides along the axial direction of the fixed boss 31. Can be done. Guide pins 33 are mounted at predetermined locations on the outer peripheral side surface of the fixed-side boss portion 31.

該ガイドピン33は、略円筒軸状に形成され、前記固定側ボス部31の所定箇所に圧入固着されている。その固定プーリ半体3の固定側ボス部31は、図11に示すように、遠心クラッチ5との間に設けられた従動軸4に回動自在に支承されている。前記可動プーリ半体Aと固定プーリ半体3と従動軸4とからなる従動プーリは、前記駆動側プーリと対をなす。   The guide pin 33 is formed in a substantially cylindrical shaft shape and is press-fitted and fixed to a predetermined portion of the fixed-side boss portion 31. As shown in FIG. 11, the fixed-side boss 31 of the fixed pulley half 3 is rotatably supported by a driven shaft 4 provided between the centrifugal clutch 5. A driven pulley comprising the movable pulley half A, the fixed pulley half 3 and the driven shaft 4 forms a pair with the driving pulley.

前記従動プーリには、図11に示すように、前記遠心クラッチが隣接して配置されている。その固定側ボス部31の軸端部には、この遠心クラッチ5を構成する駆動プレート51が固着されており、Vベルト7によって前記固定プーリ半体3に伝達された回転力は、前記固定側ボス部31を通じて前記駆動プレート51に伝えられる。次いで、遠心ウェイト52およびクラッチアウタ53を経て前記従動軸4に回転が伝達される。   As shown in FIG. 11, the centrifugal clutch is disposed adjacent to the driven pulley. A driving plate 51 constituting the centrifugal clutch 5 is fixed to the shaft end portion of the fixed side boss portion 31, and the rotational force transmitted to the fixed pulley half 3 by the V belt 7 is the fixed side boss portion 31. It is transmitted to the drive plate 51 through the boss part 31. Next, rotation is transmitted to the driven shaft 4 through the centrifugal weight 52 and the clutch outer 53.

次に、可動プーリ半体Aにおいて、ボス部材1に対して可動プーリフェイス2を接合固定する組付けについて説明する。組付けには2つの方法がある。まず、組付け方法の第1実施形態では、前記可動プーリ半体Aのボス部材1の大径円筒部12側が前記可動プーリフェイス2の円筒接合部22に挿入される。図5(A)は、大径円筒部12が前記円筒接合部22に挿入された状態の要部軸方向に直交する断面図である。このとき、前記円筒接合部22は前記鍔状部17に当接する位置まで挿入される。すなわち、該鍔状部17は、前記円筒接合部22を挿入したときの位置決め用のストッパとしての役目をなすものである。前記鍔状部17が形成されない実施形態も存在する(図9参照)。   Next, in the movable pulley half A, the assembly for fixing the movable pulley face 2 to the boss member 1 will be described. There are two methods for assembly. First, in the first embodiment of the assembling method, the large diameter cylindrical portion 12 side of the boss member 1 of the movable pulley half A is inserted into the cylindrical joint portion 22 of the movable pulley face 2. FIG. 5A is a cross-sectional view perpendicular to the axial direction of the main part in a state where the large-diameter cylindrical portion 12 is inserted into the cylindrical joint portion 22. At this time, the cylindrical joint portion 22 is inserted to a position where the cylindrical joint portion 22 comes into contact with the flange-shaped portion 17. That is, the hook-shaped portion 17 serves as a positioning stopper when the cylindrical joint portion 22 is inserted. There is also an embodiment in which the hook-like portion 17 is not formed (see FIG. 9).

次に、前記ボス部材1の大径円筒部12の外周側面部121に形成された溝状凹み部15の位置に相当する前記可動プーリフェイス2の円筒接合部22の外周側面をプレス機,カシメ専用機等の工作機械によって押圧力Pによって押圧される〔図5(B)参照〕。この工作機械によって、前記円筒接合部22の肉部を前記大径円筒部12に形成された溝状凹み部15の形状に沿って押し込まれるようにしてカシメが行われ、その円筒接合部22の肉部に塑性変形を生じさせて固定されるものである。このとき、大径円筒部12に複数の溝状凹み部15が形成されている場合には、該溝状凹み部15に形成されている位置に相当する円筒接合部22の外周箇所を同時に押圧力Pによる押圧を行うことが好ましく、迅速に組付けを行うことができるものである〔図5(B)参照〕。   Next, the outer peripheral side surface of the cylindrical joint portion 22 of the movable pulley face 2 corresponding to the position of the groove-shaped recess portion 15 formed in the outer peripheral side surface portion 121 of the large-diameter cylindrical portion 12 of the boss member 1 is pressed with a press, caulking It is pressed by the pressing force P by a machine tool such as a dedicated machine (see FIG. 5B). By this machine tool, caulking is performed so that the flesh portion of the cylindrical joint portion 22 is pushed along the shape of the groove-shaped recess portion 15 formed in the large-diameter cylindrical portion 12. The meat part is fixed by causing plastic deformation. At this time, when a plurality of groove-like recesses 15 are formed in the large-diameter cylindrical part 12, the outer peripheral portion of the cylindrical joint 22 corresponding to the position formed in the groove-like recess 15 is simultaneously pressed. It is preferable to perform the pressing with the pressure P, and the assembly can be performed quickly (see FIG. 5B).

次に、組付け方法について述べる。この組付け方法を解り易くするためカシメ用の工具6なるものを示して説明する(図6,図7参照)。まず、前述したように、ボス部材1の大径円筒部12が、可動プーリフェイス2の円筒接合部22構成に挿入される〔図6(A)参照〕。そして前記ボス部材1の段差面部14に形成された係止用窪み部16に工具6の係止嘴片61の先端が挿入され、前記可動プーリフェイス2の円筒接合部22の肉部を前記工具6の押え片嘴片62にて押さえるようにセットされる。そして、前記工具6の押え片嘴片62によって、前記円筒接合部22の肉部に押圧力をかけて、円筒接合部22にカシメを施し、前記溝状凹み部15の形状に沿って押し込むようにして塑性変形部221を形成する。   Next, the assembly method will be described. In order to make this assembling method easy to understand, the caulking tool 6 will be shown and described (see FIGS. 6 and 7). First, as described above, the large-diameter cylindrical portion 12 of the boss member 1 is inserted into the configuration of the cylindrical joint portion 22 of the movable pulley face 2 [see FIG. 6 (A)]. And the front-end | tip of the locking collar piece 61 of the tool 6 is inserted in the hollow part 16 for locking formed in the level | step difference surface part 14 of the said boss | hub member 1, and the meat | flesh part of the cylindrical junction part 22 of the said movable pulley face 2 is used as the said tool. 6 is set so as to be pressed by the pressing piece 62 of the pressing piece. Then, the pressing piece flange 62 of the tool 6 applies a pressing force to the flesh portion of the cylindrical joint portion 22 to crimp the cylindrical joint portion 22 and push it along the shape of the groove-like recess portion 15. Thus, the plastic deformation portion 221 is formed.

このようにカシメを行うことによって、可動プーリフェイス2にカシメによる塑性変形部221を生じさせ、該可動プーリフェイス2と、可動プーリ半体Aのボス部材1とを接合固着することができる。ここで、前記カシメ専用機の工具6の押え片嘴片62は、前記鍔状部17に切欠き部171が形成されているので、該切欠き部171箇所に工具の先端を差し込むようにして使用することで、カシメ作業を容易に行うことができる。   By caulking in this way, a plastically deformed portion 221 due to caulking is generated on the movable pulley face 2, and the movable pulley face 2 and the boss member 1 of the movable pulley half A can be bonded and fixed. Here, since the notch portion 171 is formed in the hook-shaped portion 17 of the presser piece piece 62 of the tool 6 of the caulking dedicated machine, the tip of the tool is inserted into the notch portion 171. By using, the caulking work can be easily performed.

さらに、図示しないが、前記溝状凹み部15は、その長手方向が前記大径円筒部12の軸方向の略全体に亘って形成され、且つ前記底面151の深さが長手方向に亘って同一に形成される実施形態も存在する。すなわち、前記底面151は傾斜面ではなく、深さが長手方向において一定となるように形成されたものである。そして、前記ボス部材1の大径円筒部12が前記可動プーリフェイス2の円筒接合部22に挿入された状態で、前記円筒接合部22の軸方向端部箇所が直径方向中心に向かって押圧されて塑性変形されることによって、前記前記大径円筒部12の軸端部も前記円筒接合部22から押圧され、塑性変形して、前記円筒接合部22と大径円筒部12とが固定される固定手段も存在する。   Further, although not shown, the groove-shaped recess 15 is formed so that the longitudinal direction thereof extends over substantially the entire axial direction of the large-diameter cylindrical portion 12, and the depth of the bottom surface 151 is the same throughout the longitudinal direction. There are also embodiments formed in That is, the bottom surface 151 is not an inclined surface, but is formed so that the depth is constant in the longitudinal direction. Then, in the state where the large diameter cylindrical portion 12 of the boss member 1 is inserted into the cylindrical joint portion 22 of the movable pulley face 2, the axial end portion of the cylindrical joint portion 22 is pressed toward the center in the diameter direction. By being plastically deformed, the shaft end portion of the large-diameter cylindrical portion 12 is also pressed from the cylindrical joint portion 22 and is plastically deformed to fix the cylindrical joint portion 22 and the large-diameter cylindrical portion 12. There are also fixing means.
