At this time, the tool gear 63 of the tool 61 is maintained in mesh with the sheave gear 13 of the sheave 4 so that the support projection 65 of the tool 61 is supported by the projection receiver 69 of the large-diameter portion 22. Insert into a hole.
この状態から、矢印Ａに示すようにハンドル６７を回すことで、ツール６１のツール歯車６３が矢印Ｂに示すように支持突起６５を支点に（ツール回転中心ＴＣまわりに）回転し、ツール歯車６３と噛み合った綱車歯車１３が矢印Ｃに示すように回転される。すなわち、綱車歯車１３において回転力を受けた綱車４が、ロータ３の支持外周面３ａの周りに回転する。これにより、雌ねじ部５１が雄ねじ部４１に締め込まれる。
From this state, by rotating the handle 67 as shown by the arrow A, the tool gear 63 of the tool 61 rotates around the support protrusion 65 (around the tool rotation center TC) as shown by the arrow B, and the tool gear 63 Is rotated as indicated by an arrow C. That is, the sheave 4 that receives the rotational force in the sheave gear 13 rotates around the support outer peripheral surface 3 a of the rotor 3. As a result, the female screw portion 51 is fastened to the male screw portion 41.
また、このとき、雄ねじ部４１および雌ねじ部５１の作用により、綱車４は、回転しながら直線的に移動する。すなわち、綱車４は、ロータ３の支持外周面３ａの周りで回転すると共に、ロータ３の大径部２２に近づくようにロータ３の回転中心線ＲＬに沿って移動する。これにより、当初の、雄ねじ部４１と雌ねじ部５１との結合に加え、第１嵌め合い部４３と第２嵌め合い部５３との面接触も発生するようになり、綱車４のロータ３に対する芯出し作用も得られる。
Further, at this time, the sheave 4 moves linearly while rotating by the action of the male screw portion 41 and the female screw portion 51. That is, the sheave 4 rotates around the support outer peripheral surface 3 a of the rotor 3 and moves along the rotation center line RL of the rotor 3 so as to approach the large diameter portion 22 of the rotor 3. Thereby, in addition to the coupling | bonding of the male thread part 41 and the female thread part 51 at the beginning, the surface contact of the 1st fitting part 43 and the 2nd fitting part 53 also generate | occur | produces, and with respect to the rotor 3 of the sheave 4 Centering action is also obtained.
以上説明したように、本実施の形態１のエレベータの巻上機の綱車の締結方法によれば、綱車の雌ねじ部とロータの雄ねじ部とにより綱車とロータとを結合するので、焼嵌めによる結合に必要なような火器の使用を強いられることなく、綱車の交換を行うことができる。また、本実施の形態１とは異なる構成として、綱車に対して、ロータの回転中心線に沿う方向から、ボルト等を挿入して、そのボルト等をロータにねじ込む態様を想定したが、そのような想定構造の場合、比較的小径の綱車では、ボルト等を差し込むスペースが綱車に十分に確保できない恐れがある。一方、本実施の形態１のエレベータの巻上機の綱車の締結方法であれば、綱車に対して、ロータの回転中心線に沿う方向から、ボルト等を挿入する必要が無いので、比較的小径の綱車に対しても、不都合なく実施することができる。また、本実施の形態１においては、雄ねじ部と雌ねじ部との結合に加えて、第１嵌め合い部と第２嵌め合い部との面接触も生じるので、綱車をロータに締め込むと共に、綱車とロータとの芯出しも完了する。なお、雄ねじ部と第１嵌め合い部との回転中心線方向の位置関係、および、雌ねじ部と第２嵌め合い部との回転中心線方向の位置関係は、上述の状態から逆にして実施することもできる。
As described above, according to the method of fastening the sheave of the elevator hoist according to the first embodiment, the sheave and the rotor are coupled by the female thread portion of the sheave and the male thread portion of the rotor. The sheaves can be replaced without being forced to use firearms that are necessary for fitting by fitting. Further, as a configuration different from the first embodiment, a mode is assumed in which a bolt or the like is inserted into the sheave from the direction along the rotation center line of the rotor and the bolt or the like is screwed into the rotor. In such an assumed structure, there is a possibility that a space for inserting bolts or the like cannot be sufficiently secured in the sheave with a relatively small diameter sheave. On the other hand, if it is the fastening method of the sheaves of the elevator hoisting machine according to the first embodiment, there is no need to insert bolts or the like from the direction along the rotation center line of the rotor with respect to the sheaves. It can be carried out without any inconvenience even with a small-diameter sheave. In the first embodiment, in addition to the coupling between the male screw portion and the female screw portion, surface contact between the first fitting portion and the second fitting portion also occurs, so that the sheave is fastened to the rotor, The centering of the sheave and the rotor is also completed. The positional relationship in the rotation center line direction between the male screw portion and the first fitting portion and the positional relationship in the rotation center line direction between the female screw portion and the second fitting portion are reversed from the above-described state. You can also.
また、本実施の形態１によれば、外部より人力で綱車、ロータ、モータを回転させることができるため、綱車交換の作業のみならず、緊急時におけるカゴ内人員の救出にも利用することができるメリットがある。
Further, according to the first embodiment, since the sheave, the rotor, and the motor can be rotated manually from outside, it is used not only for exchanging sheaves but also for rescue of personnel in the cage in an emergency. There is a merit that can be.
なお、本実施の形態１では、緩みトルク以上の必要十分な締付トルクで綱車を締結するため、緩み止め構造は、必ずしも必要はないが、裕度増しのためピン等を併用してもよい。また、締め込んだ際の最終位置を確認するための、複数個の穴もしくは溝を用意してもよい。
In the first embodiment, the sheave is fastened with a necessary and sufficient tightening torque equal to or greater than the loosening torque. Therefore, the loosening prevention structure is not necessarily required. Good. Also, a plurality of holes or grooves for confirming the final position when tightening may be prepared.

次に、本発明の実施の形態２について説明する。図４は、本実施の形態２を適用する綱車およびロータを示す図である。なお、本実施の形態２は、以下に説明する部分を除いては、上述した実施の形態１と同様であるものとする。
Next, a second embodiment of the present invention will be described. FIG. 4 is a diagram showing a sheave and a rotor to which the second embodiment is applied. The second embodiment is the same as the first embodiment described above except for the parts described below.
本実施の形態２では、ロータ３の支持外周面３ａすなわち小径部２１の外周面には、雄ねじ部４１が形成されている一方、実施の形態１のような第１嵌め合い部は形成されていない。また、綱車４の内周面には、雌ねじ部５１が形成されている一方、実施の形態１のような第２嵌め合い部は形成されていない。
In the second embodiment, the outer peripheral surface 3a of the rotor 3, that is, the outer peripheral surface of the small diameter portion 21 is formed with the male screw portion 41, while the first fitting portion as in the first embodiment is formed. Absent. Further, on the inner peripheral surface of the sheave 4, the female screw portion 51 is formed, but the second fitting portion as in the first embodiment is not formed.
実施の形態１の第１嵌め合い部４３および第２嵌め合い部５３に代えて、本実施の形態２では、ロータ３に、第３嵌め合い部１３１ａが設けられ、綱車４の綱車歯車１１３に、第３嵌め合い部１３１ａと面接触する第４嵌め合い部１１３ｂとが設けられている。
Instead of the first fitting portion 43 and the second fitting portion 53 of the first embodiment, in the second embodiment, the rotor 3 is provided with a third fitting portion 131a, and the sheave gear of the sheave 4 is provided. 113 is provided with a fourth fitting portion 113b in surface contact with the third fitting portion 131a.
綱車４の綱車歯車１１３は、上記実施の形態１と同じ歯車部分１１３ａと、第４嵌め合い部１１３ｂとを備えている。第４嵌め合い部１１３ｂは、ロータ３の大径部２２の壁部３１と対向する面である。一方、ロータ３の大径部２２の壁部３１の綱車４側の面は、第３嵌め合い部１３１ａとして機能する。
The sheave gear 113 of the sheave 4 includes the same gear portion 113a as the first embodiment and a fourth fitting portion 113b. The fourth fitting portion 113 b is a surface facing the wall portion 31 of the large diameter portion 22 of the rotor 3. On the other hand, the surface of the wall portion 31 of the large-diameter portion 22 of the rotor 3 on the sheave 4 side functions as a third fitting portion 131a.
このように構成された本実施の形態２においても、実施の形態１と同様な利点が得られる。また、ロータへの綱車のねじ込みが進んだ段階で、第３嵌め合い部と第４嵌め合い部との面接触が得られ、それによって、実施の形態１と同様、綱車をロータに締め込むと共に、綱車とロータとの芯出しも完了する。
In the second embodiment configured as described above, the same advantages as in the first embodiment can be obtained. Further, at the stage where the sheave of the sheave has been screwed into the rotor, the surface contact between the third fitting portion and the fourth fitting portion is obtained, thereby fastening the sheave to the rotor as in the first embodiment. The centering of the sheave and the rotor is also completed.
以上、好ましい実施の形態を参照して本発明の内容を具体的に説明したが、本発明の基本的技術思想及び教示に基づいて、当業者であれば、種々の改変態様を採り得ることは自明である。
Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
例えば、芯出しを目的とした嵌め合い部の形状は、上記に示したように回転中心線に直交する方向に延びるストレート形状には限定されず、テーパ形状でもよい。また、雄ねじ部と雌ねじ部とのねじ精度が、極めて高く実現されている場合には、雄ねじ部と雌ねじ部との締結だけで、ロータに対する綱車の芯出しが確保されるので、その場合は、面接触する一対の嵌め合い部は省くことができる。
For example, the shape of the fitting portion for the purpose of centering is not limited to the straight shape extending in the direction orthogonal to the rotation center line as shown above, and may be a tapered shape. In addition, when the screw accuracy of the male screw portion and the female screw portion is realized to be extremely high, the sheave centering with respect to the rotor is secured only by fastening the male screw portion and the female screw portion. The pair of fitting portions that are in surface contact with each other can be omitted.
