Description

本発明は、周方向に伸長可能なベルトを外周面にプーリ溝を有するプーリに取り付けるためのベルト取付治具に関するものである。   The present invention relates to a belt attaching jig for attaching a belt that can be extended in a circumferential direction to a pulley having a pulley groove on an outer peripheral surface thereof.

一般に、外周面にプーリ溝を有するプーリにベルトを掛巻してなるベルト伝動機構には、ベルトをプーリに取り付けてから所定のベルト張力を付与するように、テンションプーリなどの張力調整手段が設けられている。   Generally, a belt transmission mechanism in which a belt is wound around a pulley having a pulley groove on the outer peripheral surface is provided with tension adjusting means such as a tension pulley so that a predetermined belt tension is applied after the belt is attached to the pulley. It has been.

このような張力調整手段を不要にするため、プーリに取り付ける際に周方向に伸長させてプーリフランジを乗り越えさせるようにしたベルトが出現している。このベルトを使用する場合、ベルトを周方向に伸長させながらプーリフランジを乗り越えさせてプーリ溝に嵌め込むためのベルト取付治具が必要とされる。特許文献1には、ポリアミドからなる心線を用いて周方向に伸長しやすくしたベルトと、このベルトをプーリに取り付けるためのベルト取付治具とが開示されている。   In order to eliminate the need for such tension adjusting means, a belt has appeared that extends in the circumferential direction when it is attached to the pulley so as to get over the pulley flange. When this belt is used, a belt mounting jig is required to extend over the pulley flange while extending the belt in the circumferential direction so as to be fitted into the pulley groove. Patent Document 1 discloses a belt that is easily stretched in the circumferential direction using a core made of polyamide, and a belt attachment jig for attaching the belt to a pulley.

図11に、特許文献1が開示するベルト取付治具(搭載ツール)を示す。ベルト取付治具101は、プーリ102に装着して使用するものであり、その装着時にプーリ102の外周側に配置される円錐形部材103を備えている。円錐形部材103は、ベルト104を掛けることにより、プーリ102からのベルト104の外れを阻止すると共に、ベルト104の向きを変えてプーリ102の軸方向外方からプーリ溝105に導くようになっている。   FIG. 11 shows a belt mounting jig (mounting tool) disclosed in Patent Document 1. The belt attaching jig 101 is used by being attached to the pulley 102, and includes a conical member 103 disposed on the outer peripheral side of the pulley 102 when the belt attaching jig 101 is attached. The conical member 103 hangs the belt 104 to prevent the belt 104 from detaching from the pulley 102 and changes the direction of the belt 104 to guide the pulley 102 from the axially outer side of the pulley 102 to the pulley groove 105. Yes.

円錐形部材103の端部には案内平滑面106が設けられ、この案内平滑面106でベルト104の側面をプーリ溝105に向けて押さえながら、ベルト取付治具101をプーリ102の周方向に摺動させることにより、あるいはプーリ102を回転させることにより、プーリ溝105に嵌ったベルト104の範囲を広げていき、ベルト104をプーリ102に取り付けるようになっている。
特開平10−184813号公報(段落番号0012、0015、0060〜0067、図8)
A guide smooth surface 106 is provided at the end of the conical member 103, and the belt mounting jig 101 is slid in the circumferential direction of the pulley 102 while pressing the side surface of the belt 104 toward the pulley groove 105 with the guide smooth surface 106. By moving or rotating the pulley 102, the range of the belt 104 fitted in the pulley groove 105 is expanded, and the belt 104 is attached to the pulley 102.
Japanese Patent Laid-Open No. 10-184813 (paragraph numbers 0012, 0015, 0060 to 0067, FIG. 8)

ところが、特許文献1のベルト取付治具は、ベルトを掛ける円錐形部材がプーリの外周面よりも半径方向外方に突出するので、プーリへの取付が完了するまでの一時的なベルトの伸びをより大きくする。この伸びの増大や、案内平滑面で側面を擦られることにより、プーリへの取付時にベルトが損傷するおそれがある。   However, in the belt mounting jig of Patent Document 1, since the conical member for hanging the belt projects radially outward from the outer peripheral surface of the pulley, the belt is temporarily stretched until the mounting to the pulley is completed. Make it bigger. There is a risk that the belt may be damaged when it is attached to the pulley due to the increase in elongation and rubbing of the side surface with the guiding smooth surface.

本発明は、外周面にプーリ溝を有するプーリに、ベルトを損傷させることなく周方向に伸長させて取り付けることができるベルト取付治具を提供することを目的とする。   An object of this invention is to provide the belt attachment jig which can be attached to the pulley which has a pulley groove in an outer peripheral surface, extended in the circumferential direction, without damaging a belt.

上記目的を達成するために、本発明に係るベルト取付治具は、周方向に伸長可能なベルトを外周面にプーリ溝を有するプーリに取り付けるためのものであり、少なくともベルトがプーリ溝に嵌るまでこのベルト取付治具をプーリに固定するための固定手段と、ベルトの一部を保持する保持面とを備えている。   In order to achieve the above object, a belt attachment jig according to the present invention is for attaching a belt that can be extended in a circumferential direction to a pulley having a pulley groove on an outer peripheral surface, at least until the belt fits in the pulley groove. A fixing means for fixing the belt mounting jig to the pulley and a holding surface for holding a part of the belt are provided.

保持面は、ベルトの内周面の一部を受けてプーリフランジの近傍かつプーリ軸方向外側に保持するものであり、この保持面を境にして、プーリ回転方向の後方ではプーリ溝にベルトを嵌め、プーリ回転方向の前方ではプーリの軸方向外側にベルトを通すようにする。これにより、ベルトを張力のない状態でプーリおよびベルト取付治具に掛けることができる。   The holding surface receives a part of the inner peripheral surface of the belt and holds it in the vicinity of the pulley flange and outside in the pulley axial direction. With this holding surface as a boundary, the belt is placed in the pulley groove at the rear in the pulley rotation direction. The belt is passed through the outside in the axial direction of the pulley in the forward direction in the pulley rotation direction. As a result, the belt can be hung on the pulley and the belt mounting jig without tension.

保持面をプーリフランジの外周面と面一に設定することにより、ベルトがプーリ溝からプーリフランジを跨いでプーリの軸方向外側に移行する部位で、ベルトがベルト幅方向に曲がる。このベルトの曲がりに対する復元力は、保持面よりもプーリ回転方向後方のベルトがプーリ溝に嵌ってプーリ軸方向に拘束されているので、保持面よりもプーリ回転方向前方のベルトをプーリの軸方向外側からプーリ軸方向内側にあるプーリ溝に向けて移動させるように作用する。   By setting the holding surface flush with the outer peripheral surface of the pulley flange, the belt bends in the belt width direction at a portion where the belt moves from the pulley groove across the pulley flange to the outside in the axial direction of the pulley. The restoring force against the bending of the belt is such that the belt behind the pulley rotation direction with respect to the holding surface fits into the pulley groove and is restrained in the pulley axial direction. It acts to move from the outside toward the pulley groove on the inside in the pulley axial direction.

プーリを回転させたとき、これに追随してベルト取付治具も周方向に回転するので、ベルト取付治具よりもプーリ回転方向前方で、プーリの軸方向外側を通るベルトが半径方向外向きに移動してプーリフランジの外縁に徐々に近づいていく。やがて、ベルトがそのベルト幅方向の曲がりに対する復元力によってプーリフランジを乗り越え、プーリ溝に嵌ろうとする。このようにしてベルトが完全にプーリ溝に嵌るまで、保持面がベルトの一部を保持する。   When the pulley is rotated, the belt mounting jig also rotates in the circumferential direction following the rotation of the pulley, so that the belt passing in the axially outer side of the pulley is radially outward in front of the belt mounting jig in the pulley rotation direction. Move and gradually approach the outer edge of the pulley flange. Eventually, the belt moves over the pulley flange by the restoring force against the bending in the belt width direction and tries to fit into the pulley groove. In this way, the holding surface holds a part of the belt until the belt is completely fitted in the pulley groove.

このとき、保持面をプーリフランジの外周面と面一にするので、プーリに取り付ける際のベルトの一時的な伸びを最小限にすることができる。さらに、ベルト幅方向に曲がったベルトの復元力を利用して、ベルトのうちのプーリの軸方向外側に位置する部位をプーリ溝に向けて移動させるので、ベルトの側面を押圧して強制的に移動させる場合のようなベルト側面の擦れを生じさせない。このように、ベルトの伸びを極力小さくすると共に、ベルト側面の擦れを生じさせないので、プーリに取り付ける際のベルトの損傷を防止することができる。   At this time, since the holding surface is flush with the outer peripheral surface of the pulley flange, the temporary elongation of the belt when attached to the pulley can be minimized. Furthermore, by using the restoring force of the belt bent in the belt width direction, the portion of the belt that is located outside the pulley in the axial direction is moved toward the pulley groove. The belt side is not rubbed as in the case of movement. As described above, the elongation of the belt is made as small as possible and the side surface of the belt is not rubbed, so that the belt can be prevented from being damaged when attached to the pulley.

ここで、保持面をプーリフランジと面一に設定する場合には、ベルト取付治具の保持面を形成する板材の板厚分程度の差がある場合も含む。また、「面一」は、保持面の全面に限らず、その一部であってもよい。「面一」が保持面の全面の場合としては、保持面がプーリフランジの外周面と等しい曲率の場合を挙げることができる。   Here, the case where the holding surface is set flush with the pulley flange includes the case where there is a difference of about the plate thickness of the plate material forming the holding surface of the belt mounting jig. Further, “level” is not limited to the entire holding surface, but may be a part thereof. An example of the case where the “level” is the entire surface of the holding surface includes a case where the holding surface has the same curvature as the outer peripheral surface of the pulley flange.

保持面をプーリフランジの外周面と等しい曲率の曲面に設定すれば、保持面をプーリフランジの外周面と面一に設定しつつ、その面積を大きくすることができるので、ベルトをより広い面で受けることができ、ベルトの狭い範囲に強い力が作用することによるベルトの損傷を防止することができる。   If the holding surface is set to a curved surface having the same curvature as the outer peripheral surface of the pulley flange, the area can be increased while the holding surface is set flush with the outer peripheral surface of the pulley flange. It is possible to prevent the belt from being damaged by a strong force acting on a narrow range of the belt.

プーリフランジの外周面と面一な保持面をプーリ軸方向外側に設けるだけでもよいが、この保持面に連続して、プーリ溝にベルトを滑り込ませる傾斜面を形成すれば、ベルトが保持面からプーリ溝に移動しやすくなり、ベルトをよりスムーズに取り付けることができる。   A holding surface that is flush with the outer peripheral surface of the pulley flange may be provided only on the outer side in the pulley axial direction. However, if an inclined surface that allows the belt to slide into the pulley groove is formed continuously to the holding surface, the belt can It becomes easy to move to the pulley groove, and the belt can be attached more smoothly.

次に、ベルト取付治具を固定する固定手段について説明する。この固定手段としては、ベルト取付治具の一部をベルトとプーリとで挟持する構成が挙げられる。この構成によれば、ベルト取付治具の一部を挟むようにしてベルトをプーリ溝に嵌めるだけでよいので、プーリにベルト取付治具を簡単に装着することができる。なお、プーリにベルトが強く巻き付いてベルト取付治具をしっかりと挟持するまで、ベルト取付治具をプーリに仮留めしたり、手で保持したりすればよい。   Next, fixing means for fixing the belt mounting jig will be described. Examples of the fixing means include a configuration in which a part of the belt mounting jig is sandwiched between the belt and the pulley. According to this configuration, it is only necessary to fit the belt in the pulley groove so as to sandwich a part of the belt attachment jig, and therefore the belt attachment jig can be easily attached to the pulley. Note that the belt attachment jig may be temporarily fixed to the pulley or held by hand until the belt is tightly wound around the pulley and the belt attachment jig is firmly clamped.

別の固定手段として、プーリの一部を挟んでプーリに着く挟着部を例示することができる。この挟着部をプーリの一部を緩やかに挟む大きさに設定し、さらに、保持面がベルト反力を受けてベルト取付治具の一部としての挟着部が傾いたとき、プーリの一部を強固に挟むように挟着部の大きさを設定する。   As another fixing means, a sandwiching portion that sandwiches a part of the pulley and reaches the pulley can be exemplified. This clamping part is set to a size that allows a part of the pulley to be gently clamped, and when the holding part receives a belt reaction force and the clamping part as a part of the belt mounting jig is inclined, The size of the sandwiched portion is set so as to firmly sandwich the portion.

そうすれば、ベルト取付治具をプーリに装着する際は、挟着部でプーリの一部を緩やかに挟むだけなので、ベルト取付治具の装着を簡単にすることができる。さらに、ベルトを取り付ける間は、ベルト反力を利用してプーリにベルト取付治具を強固に固定することができ、ベルトの取り付け完了後は、再びベルト反力が作用しなくなって挟着部でプーリを緩やかに挟んだだけの状態になり、ベルト取付治具を容易に取り外すことができる。   In this case, when the belt attachment jig is attached to the pulley, only a part of the pulley is gently sandwiched by the sandwiching portion, so that the attachment of the belt attachment jig can be simplified. Furthermore, while attaching the belt, the belt attachment jig can be firmly fixed to the pulley using the belt reaction force. The pulley is simply pinched and the belt mounting jig can be easily removed.

プーリの側面に凹部が形成されている場合、挟着部として、プーリを凹部の内周側とプーリ溝の外周側とから挟む構造を例示できる。この構造を採用すれば、挟着部の一片がプーリ溝の外周側に位置するので、その表面をベルトに滑らせることができる。これにより、プーリの外周面に複数条の溝がある場合のように、プーリの外周面がベルトの滑りにくい状態であっても、ベルトに挟着部の表面を滑らせてスムーズにプーリ溝に嵌めることができる。   When the concave portion is formed on the side surface of the pulley, a structure in which the pulley is sandwiched from the inner peripheral side of the concave portion and the outer peripheral side of the pulley groove can be exemplified as the sandwiching portion. If this structure is adopted, since one piece of the sandwiching portion is located on the outer peripheral side of the pulley groove, the surface thereof can be slid on the belt. As a result, even if the outer peripheral surface of the pulley is in a state in which the belt is difficult to slip, as in the case where there are a plurality of grooves on the outer peripheral surface of the pulley, the belt can be smoothly slipped into the pulley groove by sliding the surface of the clamping portion. Can be fitted.

挟着部のうち、プーリ溝に外周側から対向する面をプーリ溝の外周面と等しい曲率の曲面に設定すれば、挟着部をより広い面でプーリ溝の外周面に接触させることができる。これにより、プーリに装着したベルト取付治具を安定させることができると共に、ベルト取付治具によるプーリ溝の損傷も防止することができる。   If the surface facing the pulley groove from the outer peripheral side is set to a curved surface having the same curvature as the outer peripheral surface of the pulley groove, the sandwiching portion can be brought into contact with the outer peripheral surface of the pulley groove with a wider surface. . As a result, the belt mounting jig attached to the pulley can be stabilized, and damage to the pulley groove by the belt mounting jig can be prevented.

挟着部として、プーリフランジをプーリ軸方向に挟む構造を採用することもできる。この構造によれば、プーリ溝の溝幅やプーリの凹部の大きさに関わらずベルト取付治具を装着することができ、さらに、凹部のないプーリにもベルト取付治具を装着することができる。   A structure in which the pulley flange is sandwiched in the pulley axial direction can also be employed as the sandwiching portion. According to this structure, the belt mounting jig can be mounted regardless of the groove width of the pulley groove or the size of the recess of the pulley, and further, the belt mounting jig can be mounted on a pulley without a recess. .

固定手段として、ベルト取付治具にナットを設け、このナットをプーリのセンターボルトに取り付けるようにしてもよい。そうすれば、センターボルトを利用するので、装着用の部材が不要であり、ベルト取付治具の装着を簡単にすることができる。さらに、プーリの外周面とは別の部位にベルト取付治具を固定するので、部材厚さなどに関わらず、保持面をプーリフランジの外周面に完全に一致させることができ、プーリに取り付ける際のベルトの伸びを最小限に抑えることができる。   As a fixing means, a nut may be provided on the belt attachment jig, and this nut may be attached to the center bolt of the pulley. Then, since the center bolt is used, a member for mounting is unnecessary, and mounting of the belt mounting jig can be simplified. Furthermore, since the belt mounting jig is fixed to a part different from the outer peripheral surface of the pulley, the holding surface can be completely matched with the outer peripheral surface of the pulley flange regardless of the member thickness, etc. The belt stretch can be minimized.

プーリ軸方向での外方へのベルトの外れを規制する外れ止めを設ければ、プーリを三次元的に配置した場合などのように、ベルト取付治具の保持面からベルトが外れやすいときにも、その外れを阻止することができる。   When the belt is easy to come off from the holding surface of the belt mounting jig, such as when the pulley is arranged three-dimensionally, by providing a stopper that prevents the belt from coming off in the pulley axis direction. However, it can be prevented from coming off.

以上のとおり、本発明によると、プーリフランジの外周面と面一に設定した保持面でベルトの一部を受けるので、プーリにベルトを取り付ける際の一時的なベルトの伸びを極力小さくすることができる。さらに、プーリへの固定手段を適宜選択して採用することにより、ベルト取付治具の装着を簡単にすることができる。これにより、周方向に伸長可能なベルトを、損傷することなく、かつ簡単にプーリに取り付けることができる。   As described above, according to the present invention, since a part of the belt is received by the holding surface set flush with the outer peripheral surface of the pulley flange, temporary belt elongation when attaching the belt to the pulley can be minimized. it can. Furthermore, the belt fixing jig can be easily mounted by appropriately selecting and employing a fixing means for the pulley. Thereby, the belt which can be extended in the circumferential direction can be easily attached to the pulley without being damaged.

以下、本発明に係るベルト取付治具を実施するための最良の形態について、図面を用いて説明する。第1実施形態〜第4実施形態のベルト取付治具1、2、3、4は、いずれもプーリ5の外周面に形成されたプーリ溝6にベルト7を取り付けるためのものであり、プーリ5に装着してベルト7を掛け、プーリ5を回転させることにより、ベルト7を伸長させてプーリフランジ8を乗り越えさせるものである。   Hereinafter, the best mode for carrying out the belt mounting jig according to the present invention will be described with reference to the drawings. The belt attaching jigs 1, 2, 3, 4 of the first to fourth embodiments are for attaching the belt 7 to the pulley groove 6 formed on the outer peripheral surface of the pulley 5, and the pulley 5 The belt 7 is attached to the belt 7 and the pulley 5 is rotated, so that the belt 7 is extended to get over the pulley flange 8.

ベルト7は、周方向に伸長可能とされてテンショナーなどの張力調整手段を不要にするものであり、例えばベルト本体にポリアミドからなる心線を埋設した構造とすることによって周方向の伸び率を2〜3%に設定される。なお、以下の実施形態では、ベルト7として、プーリ5の外周面に形成されたプーリ溝6の複数の溝に嵌るVリブドベルトを例示しているが、平ベルトなどのVリブドベルト以外のベルトであってもよい。   The belt 7 can be extended in the circumferential direction and does not require tension adjusting means such as a tensioner. For example, the belt 7 has a structure in which a core wire made of polyamide is embedded in the belt main body, thereby increasing the circumferential elongation rate to 2. Set to ~ 3%. In the following embodiment, the belt 7 is exemplified by a V-ribbed belt that fits into a plurality of grooves of the pulley groove 6 formed on the outer peripheral surface of the pulley 5, but is a belt other than the V-ribbed belt such as a flat belt. May be.

[First Embodiment]
FIG. 1A is a perspective view of a belt mounting jig according to the first embodiment of the present invention, and FIG. FIG. 2A is a perspective view showing a state where a belt is attached to a pulley using a belt attaching jig, and FIG. 2B is a cross-sectional view taken along the line B-B (a cross-sectional view of a main part). FIG. 3 is a diagram illustrating a state in which the sandwiching portion sandwiches the outer peripheral portion of the pulley.

ベルト取付治具1は、側面に凹部9を有するプーリ5に装着して、このプーリ5にベルト7を取り付けるためのものであり、プーリ5の外周部10を凹部9の内周側とプーリ溝6の外周側とから挟む挟着部(固定手段)11と、プーリフランジ8よりもプーリ軸方向外側でベルト7の一部を受けて保持する保持面12と、保持面12からプーリ溝6にベルト7を滑り込ませる傾斜面13とを備えている。   The belt attaching jig 1 is for attaching a belt 7 to a pulley 5 having a concave portion 9 on a side surface and attaching the belt 7 to the pulley 5. An outer peripheral portion 10 of the pulley 5 is connected to an inner peripheral side of the concave portion 9 and a pulley groove. 6, a sandwiching portion (fixing means) 11 sandwiched from the outer peripheral side, a holding surface 12 that receives and holds a part of the belt 7 outside the pulley flange 8 in the pulley axial direction, and a pulley groove 6 from the holding surface 12 And an inclined surface 13 on which the belt 7 is slid.

このベルト取付治具1は、1枚の金属板をU字形に折り曲げて、プーリ5に装着したときの外周側に表片1aを、内周側に裏片1bを形成してなり、その先端部が挟着部11とされる。表片1aの基端部表面が保持面12とされ、表片1aのうちの挟着部11と保持面12との間が傾斜面13とされる。少なくとも表片1aの表面は、ベルト7を滑らせやすいように、ベルト7との摩擦係数を例えば1以下に設定される。   This belt mounting jig 1 is formed by bending a single metal plate into a U-shape and forming a front piece 1a on the outer peripheral side and a back piece 1b on the inner peripheral side when the pulley 5 is mounted. The part is a sandwiching part 11. The surface of the base end portion of the surface piece 1a is a holding surface 12, and the space between the sandwiching portion 11 and the holding surface 12 in the surface piece 1a is an inclined surface 13. At least the surface of the surface piece 1a is set to have a friction coefficient of, for example, 1 or less so that the belt 7 can easily slide.

挟着部11は、表片1aと裏片1bとの間隔(W)をプーリ5の外周部10を半径方向に緩やかに挟む大きさに設定され、保持面12の受けるベルト反力によってわずかに傾くことにより、プーリ5の外周部10を強固に挟むようになっている。これにより、保持面12に掛けたベルト7が傾斜面13を滑ってプーリ溝6に嵌るまで、ベルト取付治具1がプーリ5に強固に固定される。   The sandwiching portion 11 is set such that the distance (W) between the front piece 1a and the back piece 1b is set so that the outer peripheral portion 10 of the pulley 5 is gently sandwiched in the radial direction. By tilting, the outer peripheral portion 10 of the pulley 5 is firmly sandwiched. Thereby, the belt attachment jig 1 is firmly fixed to the pulley 5 until the belt 7 hung on the holding surface 12 slides on the inclined surface 13 and fits into the pulley groove 6.

挟着部11の表片1aは、プーリ溝6の外周面とほぼ等しい曲率に形成され、保持部12からプーリ溝6に向けて傾斜部13を滑ったベルト7がプーリ溝6に位置する挟着部11の表片1aの表面に載った際に、そのベルト7がプーリ5になじむようになっている。   The front piece 1 a of the sandwiching portion 11 is formed with a curvature substantially equal to the outer peripheral surface of the pulley groove 6, and the belt 7 slid along the inclined portion 13 from the holding portion 12 toward the pulley groove 6 is located in the pulley groove 6. The belt 7 is adapted to the pulley 5 when it is placed on the surface of the front piece 1 a of the landing portion 11.

保持面12は、プーリ軸方向の幅をベルト7の幅よりも大きく設定され、ベルト7を掛けることができるようになっている。この保持面12は、プーリフランジ8の外周面とほぼ等しい曲率に形成され、プーリフランジ8よりもプーリ軸方向外方に、かつプーリフランジ8の外周面と実質的に面一に配置される。   The holding surface 12 is set to have a width in the pulley axial direction larger than the width of the belt 7 so that the belt 7 can be hung. The holding surface 12 is formed to have substantially the same curvature as the outer peripheral surface of the pulley flange 8, and is disposed outwardly in the pulley axial direction from the pulley flange 8 and substantially flush with the outer peripheral surface of the pulley flange 8.

挟着部11の表片1aと保持面12との高さの差は、プーリフランジ8の突出長とほぼ同じ大きさとされ、挟着部11の表片1aと保持面12とが傾斜面13を介して連続している。   The difference in height between the front piece 1a of the sandwiching portion 11 and the holding surface 12 is substantially the same as the protruding length of the pulley flange 8, and the front piece 1a of the sandwiching portion 11 and the holding surface 12 are inclined surfaces 13. Is continuous through.

次に、ベルト取付治具1を用いてプーリにベルトを取り付ける手順を説明する。まず、ベルト取付治具1をその挟着部11で外周部10を挟むようにしてプーリ5に装着する。図3(a)、(b)に示すように、挟着部11の間隔(W)は外周部10の厚さ(T)よりも大きく、挟着部11で外周部10を緩やかに挟むだけなので、ベルト取付治具1をプーリ5に容易に装着することができる。   Next, a procedure for attaching the belt to the pulley using the belt attaching jig 1 will be described. First, the belt attaching jig 1 is attached to the pulley 5 so that the outer peripheral portion 10 is sandwiched between the sandwiching portions 11. As shown in FIGS. 3A and 3B, the interval (W) between the sandwiching portions 11 is larger than the thickness (T) of the outer peripheral portion 10, and only the outer peripheral portion 10 is gently sandwiched between the sandwiching portions 11. Therefore, the belt attaching jig 1 can be easily attached to the pulley 5.

次いで、図2(a)、(b)に示すように、ベルト取付治具1よりもプーリ回転方向後方のプーリ溝6にベルト7を嵌める。ベルト取付治具1の近傍で、ベルト7をベルト幅方向に曲げるようにしてプーリフランジ8を跨ぐようにする。ベルト取付治具1の保持面12にベルト7を掛けて、ベルト取付治具1よりもプーリ回転方向前方でプーリ7よりもプーリ軸方向外方にベルト7を通す。この状態ではベルト7に張力は作用しておらず、ベルト取付治具1およびプーリ5に容易にベルト7を掛けることができる。   Next, as shown in FIGS. 2A and 2B, the belt 7 is fitted into the pulley groove 6 at the rear of the pulley rotation direction with respect to the belt mounting jig 1. In the vicinity of the belt mounting jig 1, the belt 7 is bent in the belt width direction so as to straddle the pulley flange 8. The belt 7 is hung on the holding surface 12 of the belt attachment jig 1, and the belt 7 is passed forward of the pulley rotation direction with respect to the belt attachment jig 1 and outward of the pulley 7 in the pulley axial direction. In this state, no tension is applied to the belt 7, and the belt 7 can be easily hung on the belt mounting jig 1 and the pulley 5.

プーリ5のセンターボルト14に例えば市販の工具を装着してプーリ5を回転させることにより、ベルト7を伸長させながら、ベルト取付治具1がプーリ回転方向前方に進み、ベルト7のうちのプーリ溝6に嵌る範囲が広がっていく。このとき、保持面12にベルト反力が作用して、図3(c)に示すように、挟着部11がわずかに傾くことにより、挟着部11が外周部10を強固に挟むので、ベルト7の取付時のベルト取付治具1の外れが防止される。   For example, by attaching a commercially available tool to the center bolt 14 of the pulley 5 and rotating the pulley 5, the belt mounting jig 1 advances forward in the pulley rotation direction while the belt 7 is extended, and the pulley groove in the belt 7 The range that fits in 6 expands. At this time, the belt reaction force acts on the holding surface 12, and as shown in FIG.3 (c), when the sandwiching portion 11 is slightly inclined, the sandwiching portion 11 firmly sandwiches the outer peripheral portion 10. The belt attachment jig 1 is prevented from coming off when the belt 7 is attached.

ベルト取付治具1よりもプーリ回転方向後方でベルト7がプーリ溝6に嵌ってプーリ軸方向の移動を規制されているので、プーリ回転方向前方では、ベルト幅方向に曲がったベルト7の復元力によって、ベルト7をプーリ溝6に向かって移動させる力が作用する。なお、ベルト7の復元力は、ベルト張力の分力としてのスラスト力や、ベルト7の弾性力である。   Since the belt 7 is fitted into the pulley groove 6 at the rear of the belt mounting jig 1 in the pulley rotation direction and the movement in the pulley axial direction is restricted, the restoring force of the belt 7 bent in the belt width direction at the front of the pulley rotation direction. Thus, a force for moving the belt 7 toward the pulley groove 6 acts. The restoring force of the belt 7 is a thrust force as a component force of the belt tension or an elastic force of the belt 7.

ベルト取付治具1よりもプーリ回転方向前方で、ベルト7がプーリ5の中心付近から半径方向外向きに移動して、徐々にプーリフランジ8の外縁に近づいていく。やがて、ベルト7の復元力により、ベルト7がプーリフランジ8を乗り越えるようにして、保持面12から傾斜面13およびプーリ溝6の溝底を滑ってプーリ溝6に嵌り、ベルト7が完全にプーリ5に取り付けられる。   The belt 7 moves radially outward from the vicinity of the center of the pulley 5 in front of the belt mounting jig 1 in the pulley rotation direction, and gradually approaches the outer edge of the pulley flange 8. Eventually, the restoring force of the belt 7 causes the belt 7 to get over the pulley flange 8 and slides from the holding surface 12 to the inclined surface 13 and the groove bottom of the pulley groove 6 to fit into the pulley groove 6, so that the belt 7 is completely pulled by the pulley. 5 is attached.

保持面12をプーリフランジ8の外周面と面一にしているので、ベルト7がプーリフランジ8を乗り越えやすく、さらに、プーリフランジ8を乗り越えさせる際に、ベルト7の伸びを極力小さくして、ベルト7の損傷を防止することができる。また、プーリ溝6の溝底に挟着部11の表片1aが位置するので、ベルト7にプーリ溝6の溝底を溝幅方向に容易に滑らせることができる。   Since the holding surface 12 is flush with the outer peripheral surface of the pulley flange 8, the belt 7 can easily get over the pulley flange 8, and when the pulley flange 8 gets over the belt 7, the extension of the belt 7 is made as small as possible. 7 damage can be prevented. Moreover, since the front piece 1a of the clamping part 11 is located in the groove bottom of the pulley groove 6, the groove bottom of the pulley groove 6 can be easily slid on the belt 7 in the groove width direction.

ベルト7が完全にプーリ5に取り付けられた後は、保持面12にベルト反力が作用しなくなるので、ベルト取付治具1は、再び挟着部11でプーリ5の外周部10を緩やかに挟んだだけの状態になり、プーリ5から自由落下させるなどして容易に取り外すことができる。   After the belt 7 is completely attached to the pulley 5, the belt reaction force does not act on the holding surface 12, so that the belt attaching jig 1 gently sandwiches the outer peripheral portion 10 of the pulley 5 with the clamping portion 11 again. It becomes a simple state, and can be easily removed from the pulley 5 by free-falling.

なお、図4に示すように、裏片1bを設けることなく、表片1aだけでベルト取付治具1を構成してもよい。この場合、プーリ溝6とベルト7とでベルト取付治具1を挟んで固定すればよく、プーリ溝6にベルト7が強く巻き付いてベルト取付治具1をしっかりと固定するまで、手でベルト取付治具1を保持するのがよい。   In addition, as shown in FIG. 4, you may comprise the belt attachment jig 1 only by the surface piece 1a, without providing the back piece 1b. In this case, it is only necessary to fix the belt mounting jig 1 between the pulley groove 6 and the belt 7, and the belt is manually mounted until the belt 7 is tightly wound around the pulley groove 6 and the belt mounting jig 1 is firmly fixed. It is preferable to hold the jig 1.

[Second Embodiment]
FIG. 5 is a perspective view of a belt mounting jig according to the second embodiment of the present invention, and FIG. 6 is a perspective view showing a state of attaching the belt to the pulley using the belt mounting jig.

ベルト取付治具2は、第1実施形態のベルト取付治具1とほぼ同じ構成であるが、1枚の金属板をU字形に折り曲げて、プーリ5に装着したときの外周側に表片2aを、内周側に裏片2bを形成し、表片2aおよび裏片2bの側方に挟着部15を形成したものである。表片2aの表面が保持面16とされ、表片2aのうちの挟着部15と保持面16との間が傾斜面17とされる。   The belt attachment jig 2 has substantially the same configuration as the belt attachment jig 1 of the first embodiment, but the surface piece 2a is formed on the outer peripheral side when a single metal plate is bent into a U shape and attached to the pulley 5. The back piece 2b is formed on the inner peripheral side, and the sandwiching portion 15 is formed on the side of the front piece 2a and the back piece 2b. The surface of the surface piece 2 a is the holding surface 16, and the inclined surface 17 is between the sandwiching portion 15 and the holding surface 16 in the surface piece 2 a.

このベルト取付治具2は、表片2aと裏片2bとが回転方向前端で連続しているので、その挟着部15でプーリ5の外周部10を挟むように装着されて保持面16にベルト反力を受けたとき、プーリ溝6の外周側および凹部9の内周側に加えて、外周部10の側面でも支持される。また、ベルト反力が大きくなりやすい回転方向前端を連続させるので、ベルト取付治具2の強度を高めることができる。さらに、回転方向前端の形状を適宜設定することにより、ベルト7の厚さ方向の極端な曲がりを抑えることができる。なお、他の構成は第1実施形態のベルト取付治具1と同じである。   Since the front piece 2a and the back piece 2b are continuous at the front end in the rotational direction, the belt attachment jig 2 is attached so that the outer peripheral portion 10 of the pulley 5 is sandwiched by the sandwiching portion 15 and is attached to the holding surface 16. When the belt reaction force is received, it is supported on the side surface of the outer peripheral portion 10 in addition to the outer peripheral side of the pulley groove 6 and the inner peripheral side of the concave portion 9. Further, since the front end in the rotational direction in which the belt reaction force is likely to increase is continued, the strength of the belt mounting jig 2 can be increased. Furthermore, extreme bending in the thickness direction of the belt 7 can be suppressed by appropriately setting the shape of the front end in the rotation direction. Other configurations are the same as those of the belt mounting jig 1 of the first embodiment.

[Third Embodiment]
FIG. 7 is a perspective view of a belt mounting jig according to the third embodiment of the present invention, and FIG. 8 is a perspective view showing a state in which the belt is attached to the pulley using the belt mounting jig.

ベルト取付治具3は、第1実施形態のベルト取付治具1とほぼ同じ構成であるが、1枚の金属板をプーリフランジ8の外周面とほぼ同じ曲率で湾曲させて保持面18とし、傾斜面を設けることなく、保持面18の側方にプーリフランジ8をプーリ軸方向に挟む挟着部19を形成したものである。   The belt mounting jig 3 has substantially the same configuration as the belt mounting jig 1 of the first embodiment, but a single metal plate is curved with substantially the same curvature as the outer peripheral surface of the pulley flange 8 to form a holding surface 18. A sandwiching portion 19 is formed on the side of the holding surface 18 to sandwich the pulley flange 8 in the pulley axial direction without providing an inclined surface.

ベルト取付治具3のプーリ回転方向前端部20は、その曲率を小さくされてプーリ5の半径方向内向きに延設され、ベルト取付治具3に掛けたベルト7の厚さ方向の曲がりを抑えると共に、保持面18がベルト反力を受けたときに、プーリ5の外周部10の側面で支持されるようになっている。   The pulley rotation direction front end portion 20 of the belt mounting jig 3 has a reduced curvature and extends inward in the radial direction of the pulley 5 to suppress bending of the belt 7 in the thickness direction on the belt mounting jig 3. At the same time, when the holding surface 18 receives a belt reaction force, the holding surface 18 is supported on the side surface of the outer peripheral portion 10 of the pulley 5.

ベルト取付治具3のプーリ回転方向後端部は、プーリ5の半径方向外向きに折曲され、プーリ軸方向で外方へのベルト7の外れを規制する外れ止め21される。外れ止め21より、複数のプーリ5を3次元的に配置した場合のように、ベルト7の外れやすいときにもベルト取付治具3からのベルト7の外れを防止する。   The rear end portion of the belt mounting jig 3 in the pulley rotation direction is bent outward in the radial direction of the pulley 5, and is prevented from coming off 21 that restricts the belt 7 from coming off in the pulley axial direction. The belt stopper 7 prevents the belt 7 from coming off from the belt mounting jig 3 even when the belt 7 is easily detached, as in the case where the plurality of pulleys 5 are arranged three-dimensionally.

挟着部19は、2種類で合計3つの突片19a、19bからなり、それぞれの突片19a、19bの先端に爪部19cが形成されている。両端の突片19aは、中央の突片19bよりもその突出長を長くされ、突片19aの爪部19cと突片19bの爪部19cとでプーリフランジ8をプーリ軸方向に挟むようになっている。   The sandwiching part 19 is composed of two kinds of protrusions 19a and 19b in total, and a claw part 19c is formed at the tip of each protrusion 19a and 19b. The protruding pieces 19a at both ends have a longer protruding length than the protruding piece 19b at the center, and the claw portion 19c of the protruding piece 19a and the claw portion 19c of the protruding piece 19b sandwich the pulley flange 8 in the pulley axial direction. ing.

突片19aの突出長と突片19bの突出長との差は、爪部19cでプーリフランジ8を緩やかに挟む大きさに設定され、ベルト反力を受けたベルト取付治具3がわずかに傾くことにより、挟着部19がプーリフランジ8を強固に挟むようになっている。この挟着部19の構成により、プーリ5の側面に凹部9のない場合にも使用することができる。なお、他の構成は、第1実施形態のベルト取付治具1と同じである。   The difference between the projecting length of the projecting piece 19a and the projecting length of the projecting piece 19b is set such that the pulley flange 8 is gently sandwiched by the claw portion 19c, and the belt mounting jig 3 receiving the belt reaction force is slightly inclined. Thereby, the clamping part 19 clamps the pulley flange 8 firmly. Due to the configuration of the sandwiching portion 19, it can be used even when there is no recess 9 on the side surface of the pulley 5. Other configurations are the same as those of the belt mounting jig 1 of the first embodiment.

ベルト取付治具4は、第1実施形態のベルト取付治具1とほぼ同じ構成であるが、1枚の金属板を折り曲げた構造とする代わりに、略楕円形の厚板22から構成し、挟着部を設ける代わりに、プーリ5のセンターボルト14に取り付けるためのナット(固定手段)23を設け、傾斜面を設けることなく、厚板22の周面に保持面24を設けたものである。   The belt mounting jig 4 has substantially the same configuration as the belt mounting jig 1 of the first embodiment, but instead of having a structure in which a single metal plate is bent, the belt mounting jig 4 is configured by a substantially elliptical thick plate 22; Instead of providing a clamping part, a nut (fixing means) 23 for attaching to the center bolt 14 of the pulley 5 is provided, and a holding surface 24 is provided on the peripheral surface of the thick plate 22 without providing an inclined surface. .

ナット23は、厚板22の側面にその中心から偏心させて設けられ、ベルト取付治具4をプーリ5に装着した状態で、ナット23から離れた部位がプーリフランジ8の外周面に接近するようになっている。図9に示すように、ナット23にはレンチ用穴25が設けられ、図10に示すように、レンチ26を用いてプーリ5のセンターボルト14に取り付けるようになっている。   The nut 23 is provided on the side surface of the thick plate 22 so as to be decentered from the center thereof, so that the portion away from the nut 23 approaches the outer peripheral surface of the pulley flange 8 with the belt mounting jig 4 attached to the pulley 5. It has become. As shown in FIG. 9, the nut 23 is provided with a wrench hole 25 and is attached to the center bolt 14 of the pulley 5 using a wrench 26 as shown in FIG.

ナット23を固定手段とする構成により、ベルト反力の有無に関わらず、プーリ5にベルト取付治具4が取り付けられる。また、プーリ5の側面に凹部9のない場合にも使用することができる。   With the configuration using the nut 23 as a fixing means, the belt attaching jig 4 is attached to the pulley 5 regardless of the presence or absence of the belt reaction force. It can also be used when there is no recess 9 on the side surface of the pulley 5.

厚板22の周面のうち、ナット23から離れた部位は、プーリフランジ8と同じ曲率で、かつプーリフランジ8と完全に面一に設定され、この部位がベルト7の一部を保持する保持面24とされる。保持面24のプーリ回転方向後端部には、突起が形成され、この突起がベルト7の外れを規制する外れ止め27とされる。なお、他の構成は、第1実施形態のベルト取付治具1と同じである。   Of the peripheral surface of the thick plate 22, the part away from the nut 23 is set to have the same curvature as the pulley flange 8 and completely flush with the pulley flange 8, and this part holds the part of the belt 7. The surface 24 is used. A protrusion is formed at the rear end of the holding surface 24 in the pulley rotation direction, and this protrusion serves as a detent 27 that restricts the belt 7 from coming off. Other configurations are the same as those of the belt mounting jig 1 of the first embodiment.
