Description

明 細 書 エレべ一夕用巻上機 技術分野  Description Elevator overnight hoist Technical field
この発明は、 主索を介してかごを昇降させるエレべ一夕用卷上機に関するもの である。 背景技術  The present invention relates to a hoisting machine for raising and lowering a car via a main rope. Background art
従来のエレべ一夕用卷上機においては、 駆動モ一夕により回転される回転軸に、 回転軸とは別部材の駆動シーブが固着されている。 駆動シ一ブには、 ロープ溝が 形成されており、 かごを吊り下げる主索が卷き掛けられている。  In the conventional elevator hoisting machine, a driving sheave, which is a member separate from the rotating shaft, is fixed to the rotating shaft rotated by the driving motor. A rope groove is formed in the drive sheave, and a main rope for suspending the car is wound therearound.
駆動シーブは、 ロープ荷重を常に受け、 トラクシヨン力を発生させながら.円滑 に回転する機能を要求される。 このため、 駆動シ一ブは、 十分な硬度及び強度を 有し、 精度良く加工する必要がある。 また、 駆動モー夕からの大きな卷上トルク を伝達するため、 駆動シ一ブは、 焼き嵌めやキーを用いるなどの方法で、 回転軸 に強固に嵌合される。 従って、 従来の駆動シ一ブは、 厚肉の高強度鎵物により構 成されており、 エレべ一夕用卷上機の小形軽量化の妨げとなっている。  The drive sheave is required to be able to smoothly rotate while receiving the rope load and generating traction force. For this reason, the drive sheave must have sufficient hardness and strength and be processed with high accuracy. In addition, in order to transmit a large winding torque from the drive motor, the drive sheave is firmly fitted to the rotating shaft by a method such as shrink fitting or using a key. Therefore, the conventional drive sheave is made of a thick, high-strength material, which hinders the reduction in size and weight of the elevator for the elevator.
また、 鋼製ロープからなる主索を用いる場合、 鋼製口一プの柔軟性等の点から、 In addition, when a main rope made of steel rope is used, the flexibility of the steel
D/d (駆動シ一ブ径 /主索径） を 4 0以上とすることが要求されており、 これ によっても駆動シーブが大形化してしまう。 D / d (drive sheave diameter / main rope diameter) is required to be 40 or more, which also increases the size of the drive sheave.
これに対し、 近年、 合成繊維ロープからなる主索が実現されている。 このよう な合成繊維ロープは、 高い摩擦係数を持ち可撓性に優れているため、 D/dを 2 5程度まで下げることが可能となり、 駆動シーブの小形化が可能となる。  In contrast, main ropes made of synthetic fiber ropes have recently been realized. Since such a synthetic fiber rope has a high coefficient of friction and excellent flexibility, it is possible to reduce D / d to about 25 and to reduce the size of the driving sheave.
しかし、 特に大形のエレペータに用いられる大容量の巻上機では、 回転軸の径 が太いため、 駆動シープの径を小さくすると、 駆動シーブの径と回転軸の径との 差が小さくなる。 即ち、 駆動シーブの径を最小限とすると、 駆動シーブが薄肉と なり、 駆動シ一ブの製造、 回転軸への嵌め込みが難しくなつてしまう。 このため、 製造及び組立の点から駆動シーブの小形化、 ひいては卷上機の小形軽量化が制限 される恐れがある。 発明の開示 However, especially in a large-capacity hoist used for a large-sized erepeater, since the diameter of the rotating shaft is large, when the diameter of the driving sheep is reduced, the difference between the diameter of the driving sheave and the diameter of the rotating shaft is reduced. That is, when the diameter of the drive sheave is minimized, the drive sheave becomes thinner, and it becomes difficult to manufacture the drive sheave and to fit it into the rotating shaft. For this reason, miniaturization of the drive sheave and, consequently, reduction of the size and weight of the hoist are limited in terms of manufacturing and assembly. May be done. Disclosure of the invention

The purpose is to obtain.

次に、 図 2は図 1の主索 7の構造を示す斜視図である。 図において、 心線 2 1 の周囲には、 複数本の内部ストランド 2 2と、 これらの内部ストランド 2 2間の 間隙に配置されている充填ストランド 2 3とを有する内部ストランド層 2 4が配 置されている。 各内部ストランド 2 2は、 複数本のァラミ ド繊維とポリウレタン 等の含浸材とにより構成されている。 充填ストランド 2 3は、 例えばポリアミ ド により構成されている。  Next, FIG. 2 is a perspective view showing the structure of the main rope 7 in FIG. In the figure, an inner strand layer 24 having a plurality of inner strands 22 and a filling strand 23 arranged in a gap between the inner strands 22 is disposed around the core wire 21. Have been. Each internal strand 22 is composed of a plurality of aramide fibers and an impregnating material such as polyurethane. The filling strand 23 is made of, for example, polyamide.
内部ストランド層 2 4の外周には、 複数本の外部ストランド 2 5を有する外部 ストランド層 2 6が配置されている。 各外部ストランド 2 5は、 内部ストランド 2 2と同様に、 複数本のァラミ ド繊維とポリウレタン等の含浸材とにより構成さ れている。  An outer strand layer 26 having a plurality of outer strands 25 is arranged on the outer periphery of the inner strand layer 24. Each outer strand 25, like the inner strand 22, is composed of a plurality of aramide fibers and an impregnating material such as polyurethane.
内部ストランド層 2 4と外部ストランド層 2 6との間には、 ストランド 2 2 , 2 5相互間の摩擦によるストランド 2 2， 2 5の摩耗を避けるための摩擦低減被 覆層 2 7が配置されている。 また、 外部ストランド層 2 6の外周部には、 保護被 覆層 2 8が配置されている。  Between the inner strand layer 24 and the outer strand layer 26, a friction-reducing coating layer 27 is disposed to avoid wear of the strands 22 and 25 due to friction between the strands 22 and 25. ing. In addition, a protective coating layer 28 is arranged on the outer periphery of the outer strand layer 26.
このような合成繊維ロープは、 鋼製ロープに比べて、 高い摩擦係数を持ち可撓 性に優れている。 上記のように構成されたエレべ一夕用卷上機においては、 別体の駆動シ一ブを 用いず、 主索卷掛部 6 aが回転軸 6に一体に形成されているため、 部品点数を削 減することができ、 また焼き嵌めゃキ一加工が不要となり、 組立を容易にするこ とができる。 また、 主索卷掛部 6 aの径を最小限にして、 全体の小形軽量化を図 ることができる。 Such a synthetic fiber rope has a higher coefficient of friction and is more flexible than a steel rope. In the hoisting machine for an elevator constructed as described above, the main cable hooking portion 6a is formed integrally with the rotary shaft 6 without using a separate drive sheave. The number of points can be reduced, and shrink-fitting machining is not required, so that assembly can be facilitated. In addition, the diameter of the main rope winding portion 6a can be minimized, so that the overall size and weight can be reduced.
このようなエレべ一夕用卷上機は、 主索卷掛部 6 aの径を十分に確保すれば、 鋼製ロープからなる主索にも使用することができるが、 小形軽量化を図るために は、 合成繊維口一プからなる主索 7に対して使用するのが効果的である。  Such a hoisting machine for an elevator can be used for a main rope made of a steel rope if the diameter of the main rope hooking section 6a is sufficiently secured, but it is intended to reduce the size and weight. For this purpose, it is effective to use it for the main rope 7 consisting of a synthetic fiber mouthpiece.
また、 主索卷掛部 6 aは回転軸 6と同様の材料により構成されているため、 鋼 製口一プを使用するとロープ溝 6 bが摩耗しやすい。 これに対し、 合成繊維口一 プの場合、 ロープ溝 6 bは摩耗しにくくなる。 さらに、 合成繊維ロープの場合、 高い摩擦係数を持っため、 摩擦力を上げるためのアンダカット溝をロープ溝 6 b 内に設ける必要がなく、 これらの点からも合成繊維ロープからなる主索 7に対し て使用するのが効果的である。  In addition, since the main rope winding portion 6a is made of the same material as the rotating shaft 6, the use of the steel mouthpiece easily causes the rope groove 6b to be worn. On the other hand, in the case of a synthetic fiber opening, the rope groove 6b is less likely to be worn. Furthermore, since the synthetic fiber rope has a high coefficient of friction, it is not necessary to provide an undercut groove in the rope groove 6b to increase the frictional force. It is effective to use it.
また、 回転軸 6と一体の主索卷掛部 6 aの端面を利用してブレーキディスク 1 2を取り付けることができるため、 ブレーキディスク 1 2を簡単かつ強固に回転 軸 6に固定することができる。 実施の形態 2 .  In addition, since the brake disc 12 can be attached using the end surface of the main rope hooking portion 6a integrated with the rotating shaft 6, the brake disc 12 can be easily and firmly fixed to the rotating shaft 6. .
