Description
本発明は、インナーロータ型巻上機に関するものである。
The present invention relates to an inner rotor type hoisting machine.
例えば、特許文献１に開示のエレベータ用巻上機では、制動器（バネと電磁マグネットを組合せたタイプ）が、電動機の内側の綱車と一体となった椀状体の内部に設置されている構造を有する。この構造では、綱車と一体となった椀状体の内部に制動器を設置することで、巻上機の薄型の実現を目指している。
For example, in an elevator hoist disclosed in Patent Document 1, a structure in which a brake (a type in which a spring and an electromagnetic magnet are combined) is installed inside a saddle that is integrated with a sheave inside an electric motor. Have This structure aims to realize a thin hoisting machine by installing a brake inside the saddle that is integrated with the sheave.
しかしながら、特許文献１に開示の構造を用いた場合、実際に薄型の制動器を製造するためには、さらに次のような課題が考えられる。
まず、素材選定の観点として、電磁吸引力とバネとの組合せでブレーキを構成する場合、小さなスペースで大きな動力を発生させる必要があるが、設置空間の制約が厳しく、特殊な素材を使う必要がある。
また、熱設計の観点として、ブレーキを動作させる際、電磁マグネット（コイル）に流す電流が高いほど吸引力が高くなるが、椀状体内部に熱がこもるため流せる電流に限りがある。
さらに、保守性の観点として、エレベータ機器のレイアウトにて、綱車をカゴ側に向けたレイアウトが求められているが、椀状体内部にブレーキが設置されているため、ブレーキのメンテナンスは綱車と反対側から行う必要があり、綱車を壁側に配置するレイアウトには対応しにくい。 However, when the structure disclosed inPatent Document 1 is used, the following problems can be further considered in order to actually manufacture a thin brake.
First, from the viewpoint of material selection, when a brake is configured with a combination of electromagnetic attractive force and a spring, it is necessary to generate a large amount of power in a small space, but there are severe restrictions on the installation space, and it is necessary to use a special material. is there.
From the viewpoint of thermal design, when operating the brake, the higher the current flowing through the electromagnetic magnet (coil), the higher the attractive force. However, there is a limit to the current that can flow because heat is trapped inside the rod-shaped body.
Furthermore, from the standpoint of maintainability, the elevator equipment layout requires a layout with the sheave facing the cage side, but because the brake is installed inside the cage, the maintenance of the brake is a sheave. Therefore, it is difficult to cope with the layout in which the sheave is arranged on the wall side.

Hereinafter, embodiments of an inner rotor type hoist according to the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

In the hoistway, a car and a counterweight are provided so as to be able to move up and down. These cages and counterweights are suspended from a rope driven by a hoist.
本実施の形態１のインナーロータ型巻上機の詳細について説明する。図１は、本発明の実施の形態１のインナーロータ型巻上機の正面図である。図２は、図１のＩＩ－ＩＩ線に沿う断面を示す。なお、本願では、回転する部分を明確に示すことを優先し、図面では、回転する部分に網掛けをマークし、ハッチングは網掛けと干渉しないように省略している。
Details of the inner rotor type hoisting machine of the first embodiment will be described. FIG. 1 is a front view of an inner rotor type hoist according to Embodiment 1 of the present invention. FIG. 2 shows a cross section taken along line II-II in FIG. In the present application, priority is given to clearly showing the rotating portion, and in the drawing, the rotating portion is marked with shading, and hatching is omitted so as not to interfere with the shading.
インナーロータ型巻上機１は、電動機３がロータ（椀状体）５の外側に配置されている。ロータ５の内部（径方向内側）には、コイルとブレーキバネ７ａとを含む電磁マグネットブレーキ７を持つ。電磁マグネットブレーキ７は、ロータ５の径方向内向きの制動面９に対して、径方向内側に位置しており、径方向外側に向けて制動面９を押圧し、ロータ５に制動力を付与する。
In the inner rotor type hoist 1, the electric motor 3 is arranged outside the rotor (saddle-like body) 5. Inside the rotor 5 (in the radial direction), there is an electromagnetic magnet brake 7 including a coil and a brake spring 7a. The electromagnetic magnet brake 7 is located radially inward with respect to the radially inward braking surface 9 of the rotor 5, and presses the braking surface 9 toward the radially outer side to apply a braking force to the rotor 5. To do.
さらに、電磁マグネットブレーキ７の径方向内側であって、ロータ５の回転軸心付近には、綱車１１が設けられている。換言すると、ロータ５の制動面９の径方向内側であって、且つ、綱車１１の径方向外側に、電磁マグネットブレーキ７が設けられている。電磁マグネットブレーキ７は、ロータ５のブレーキと、綱車１１のロープ外れ止めとを、兼ねている。図１において、符号Ｄで示される隙間を適切に設計することで、好適な外れ止めが得られる。
Further, a sheave 11 is provided on the inner side in the radial direction of the electromagnetic magnet brake 7 and in the vicinity of the rotational axis of the rotor 5. In other words, the electromagnetic magnet brake 7 is provided on the radially inner side of the braking surface 9 of the rotor 5 and on the radially outer side of the sheave 11. The electromagnetic magnet brake 7 serves as a brake for the rotor 5 and a rope detachment stop for the sheave 11. In FIG. 1, a suitable detachment prevention can be obtained by appropriately designing the gap indicated by the symbol D.
ロータ５は、綱車１１側が凹んでいる。ロータ５は、その一部として、回転軸部分５ａを備えている。回転軸部分５ａは、ロータ５の回転軸線ＲＡに沿って突出した円柱状の部分である。回転軸線ＲＡは、回転軸部分５ａの一部を通っている。綱車１１は、回転軸部分５ａの端部に取り付けられている。一例であるが、綱車１１は、ロータ５とは別に成形されており、すなわち、ロータ５とは別体である。綱車１１に、回転軸部分５ａが挿通されている。また、綱車１１には、かご等に接続されるロープ１３が巻き掛けられている。
The rotor 5 is recessed on the sheave 11 side. The rotor 5 includes a rotating shaft portion 5a as a part thereof. The rotation shaft portion 5 a is a columnar portion that protrudes along the rotation axis RA of the rotor 5. The rotation axis RA passes through a part of the rotation shaft portion 5a. The sheave 11 is attached to the end of the rotating shaft portion 5a. As an example, the sheave 11 is formed separately from the rotor 5, that is, is separate from the rotor 5. The rotary shaft portion 5a is inserted through the sheave 11. A rope 13 connected to a car or the like is wound around the sheave 11.
ロータ５は、ベアリングを介してハウジングに組付けられており、回転軸部分５ａを含むロータ５と、綱車１１とが一体的に、回転される。なお、ロータ５における電磁マグネットブレーキ７の側方（綱車と反対側）には、保守用穴５ｂが設けられていてもよい。
The rotor 5 is assembled to the housing via a bearing, and the rotor 5 including the rotating shaft portion 5a and the sheave 11 are rotated integrally. A maintenance hole 5 b may be provided on the side of the electromagnetic magnet brake 7 in the rotor 5 (on the side opposite to the sheave).
以上のように構成されたインナーロータ型巻上機によれば、これまで電動機側に凹部を向けていた椀状体を、綱車側に向けることによりブレーキを綱車側に配置することが可能となった。これにより巻上ロープに干渉しない範囲でブレーキを大型化できるため、ブレーキ本体は綱車とラップすることが可能となった。なお、綱車とラップすることが必要でない場合は、ブレーキ本体はラップせずにブレーキに取り付け部品のみラップしてもよい。
According to the inner rotor type hoisting machine configured as described above, the brake can be arranged on the sheave side by directing the saddle-like body that has been facing the recess toward the motor side toward the sheave side. It became. As a result, the brake can be enlarged in a range that does not interfere with the hoisting rope, so that the brake body can be wrapped with the sheave. In addition, when it is not necessary to wrap with a sheave, you may wrap only a component attached to a brake, without wrapping a brake main body.
また、これにより、素材選定、熱設計および保守性の観点で好適なインナーロータ型巻上機を提供することができる。すなわち、素材選定の観点では、スペースの制約が取り払われたため形状の自由度が上がり、加工性のよい丸型のブレーキなどの採用が可能となる。またブレーキを大型化することにより、安価な素材（一般構造用圧延鋼板など）の採用が容易となる。また、熱設計の観点では、ブレーキの一部が綱車側に露出するため放熱性がよく、大電流によりブレーキの動作力を増やし、電線量を減らすことが容易である。また必要であればロープと干渉しない範囲で放熱フィン等の放熱対策要部品を取り付けることにより、容易に放熱することが可能となる。さらに保守性の観点では、ブレーキが綱車側に配置されているため、綱車をカゴ側に配置するレイアウトが可能である。また、もし電動機側からブレーキをメンテナンスする必要がある場合、椀状体（構造によってはハウジングを含む）に部分的に穴を空けておくことで、電動機側からブレーキをメンテナンスすることも許容できる。またブレーキが綱車側に配置され、かつ綱車とラップする場合、ブレーキ本体の構造部品で綱車の周囲を覆うことにより、ブレーキ本体をロープ外れ止めとし、またカバーを取り付けるための土台とすることも可能である。
In addition, this makes it possible to provide an inner rotor type hoisting machine suitable from the viewpoints of material selection, thermal design, and maintainability. That is, from the viewpoint of material selection, since the space restriction is removed, the degree of freedom of shape is increased, and a round brake having good workability can be employed. Further, by increasing the size of the brake, it becomes easy to adopt inexpensive materials (such as general structural rolled steel sheets). In terms of thermal design, part of the brake is exposed on the sheave side, so heat dissipation is good, and it is easy to increase the operating force of the brake with a large current and reduce the amount of wires. Further, if necessary, it is possible to easily dissipate heat by attaching heat radiation countermeasure parts such as heat radiation fins within a range not interfering with the rope. Furthermore, from the viewpoint of maintainability, since the brake is disposed on the sheave side, a layout in which the sheave is disposed on the cage side is possible. If it is necessary to maintain the brake from the motor side, it is also possible to maintain the brake from the motor side by partially making a hole in the bowl (including the housing depending on the structure). When the brake is arranged on the sheave side and wraps with the sheave, the brake body is protected from the rope by covering the periphery of the sheave with the structural parts of the brake body, and also serves as a base for attaching the cover. It is also possible.
また機械室レスエレベータにおいて、巻上機の綱車を手前にして配置するという要求に対しては、綱車と反対側のロータ内部にブレーキが設置されるため、綱車側からのブレーキ保守ができないという問題が生じ得る。これに対し、本実施の形態では、ブレーキを綱車側に配置することにより、このような保守性の問題を回避することも可能であろう。
In addition, in a machine room-less elevator, a brake is installed inside the rotor on the opposite side of the sheave in response to the requirement that the sheave of the hoist is placed in front. The problem of not being able to occur can arise. On the other hand, in this embodiment, it is possible to avoid such a problem of maintainability by arranging the brake on the sheave side.
