本考案はワイヤの端をプーリに固定する場合の
プーリとワイヤとの組合せ構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combination structure of a pulley and a wire when the end of the wire is fixed to the pulley.

ヤロープの端である固定部分がワイヤロープの径
と比較して相当大きな形状となり、コンパクトに
固定することがむつかしくなる。 Conventionally, when fixing the end of a wire rope, it is common to fix it using various terminal fittings, such as threaded terminal fittings, or by engaging the end of a wire rope wound in a ring shape. It is true. However, when fixing the end of a wire rope to a thin pulley, if the above-mentioned fixing method is used, the fixed part, which is the end of the wire rope, becomes considerably large in shape compared to the diameter of the wire rope, making it difficult to fix it compactly. It becomes difficult.
そこで、本考案は上述の欠点に鑑み、プーリへ
のワイヤロープの固定を簡易かつコンパクトにし
たプーリとワイヤロープの組合せ構造の提供を目
的とする。 Therefore, in view of the above-mentioned drawbacks, the present invention aims to provide a combination structure of a pulley and a wire rope, which makes fixing the wire rope to the pulley simple and compact.

筒部材を嵌入させたことを特徴とする。 In order to achieve this object, the present invention provides a combination structure of a wire rope and a pulley around which the wire rope can be wound, in which a cylindrical member is fitted to the end of the wire rope, and the wire rope winding groove of the pulley is fitted with a cylindrical member. A counterbore hole into which the cylindrical member can fit is bored in the tangential direction, and the cylindrical member is fitted into the counterbore hole.
ここで、第１図ないし第５図を参照して本考案
の実施例を説明する。第１図に示すように、直径
ｄを有するワイヤロープ１の端は直径Ｄを有する
筒部材である端末金具２が固定されている。 An embodiment of the present invention will now be described with reference to FIGS. 1 to 5. As shown in FIG. 1, a terminal fitting 2, which is a cylindrical member having a diameter D, is fixed to the end of a wire rope 1 having a diameter d.
一方、プーリ３の外周部にはワイヤロープ溝４

２の径より若干大きなＤ＋αの径を有する座ぐり
穴６が溝５の中心と中心を一致させて形成されて
いる。このため、溝５には座ぐり穴６の端面部分
７を有する。 On the other hand, a wire rope groove 4 is formed on the outer periphery of the pulley 3.
is formed. In communication with this, a smoothly curved arc-shaped groove 5 is formed on the radial center side of the pulley 3, and the diameter of this groove 5 is set to be a diameter d+α slightly larger than the diameter d of the wire rope 1. Therefore, the wire rope 1 can pass through the groove 5 and be smoothly curved and stretched from the groove 5 into the wire rope groove 4. Further, a counterbore hole 6 having a diameter D+α slightly larger than the diameter of the terminal fitting 2 is formed in the groove 5 so that the center of the groove 5 coincides with the center. For this purpose, the groove 5 has an end face portion 7 of a counterbore hole 6.
このような構造の溝５及び座ぐり穴６に第１図

２図に示すＢ方向に挿入してワイヤロープ１に固
定された端末金具２を座ぐり穴６内の端面部分７
で止め、プーリ３に固定する。ワイヤロープ１を
座ぐり穴６から取外すに当つては、Ｂ方向と逆に
端末金具２を戻し、ワイヤロープ１を抜けばワイ
ヤロープ１を簡単に取外すことができる。 When installing the wire rope 1 and the terminal fitting 2 shown in FIG. 1 in the groove 5 and counterbore hole 6 of such a structure, the wire rope 1 is placed in the direction B of the counterbore hole 6 as shown in FIG. The terminal fitting 2 inserted and fixed to the wire rope 1 is inserted into the end face portion 7 in the counterbore hole 6.
and secure it to pulley 3. When removing the wire rope 1 from the counterbore hole 6, the wire rope 1 can be easily removed by returning the terminal fitting 2 in the opposite direction to direction B and pulling out the wire rope 1.
以上説明したように本考案によれば、座ぐり穴

ンパクトになる。そして、固定力は端末金具の締
付力以上である。更に、端末金具の径が溝幅より
大きいので、端末金具はプーリの半径方向の規制
を受け、トラブルにてワイヤロープの張力が無く
なつた場合でも、ワイヤロープはプーリから外れ
ることがなく、安定した結合が行なわれる。 As explained above, according to the present invention, the wire rope can be easily fixed and removed by drilling counterbore holes, and the fixed part can be made very compact. The fixing force is greater than the tightening force of the terminal fitting. Furthermore, since the diameter of the terminal fitting is larger than the groove width, the terminal fitting is restricted in the radial direction of the pulley, so even if the wire rope loses tension due to trouble, the wire rope will not come off the pulley and will remain stable. The following combination is performed.
