Description

本発明は、エレベータ用巻上機の冷却構造に関するものである。 The present invention relates to a cooling structure for an elevator hoist.

エレベータ用巻上機の電動機から発生する熱を冷却する構造としては、電動機の外周側端部に冷却用ブロアを設け、ダクトを経由して電動機内部に冷却風を送るようにしたものがある。そして、電動機内部には整風板を設けることにより固定子や回転子の方へ冷却風が流れるようにして冷却している。
（例えば、特許文献１参照） As a structure for cooling the heat generated from the electric motor of the elevator hoisting machine, there is a structure in which a cooling blower is provided at an outer peripheral side end portion of the electric motor and cooling air is sent into the electric motor via a duct. And by providing an air conditioning plate inside the electric motor, cooling is performed so that cooling air flows toward the stator and the rotor.
(For example, see Patent Document 1)

特開平４−３３５３９（第１図）JP-A-4-33539 (FIG. 1)

しかしながら、冷却用ブロアを電動機の外周側に設けることにより巻上機は大型化する。また、固定子や回転子の方へ冷却風を送るためにダクトや整風板を設ける必要があり構造が複雑である。 However, the hoisting machine is enlarged by providing the cooling blower on the outer peripheral side of the electric motor. Further, it is necessary to provide a duct and a wind regulation plate in order to send cooling air toward the stator and the rotor, and the structure is complicated.

本発明は、かかる問題を解決するためになされたもので、小型で簡単な冷却構造を有するエレベータ用巻上機を得ることを目的とする。 The present invention has been made to solve such a problem, and an object thereof is to obtain an elevator hoisting machine having a small and simple cooling structure.

本発明に係るエレベータ用巻上機は、一端側は壁で塞がれ、他端側は開口され、壁には他端側に対向する穴を有する筒状の枠体と、壁から他端側へ突出して設けられた軸と、軸を中心にして枠体の内側に固定された円環状の固定子と、中空円筒形状をしており、外周面は固定子の内周面に第１の隙間を開けて対向し、壁側端面は壁に第２の隙間を開けて対向するとともに穴よりも径方向外側に位置し、壁とは反対側の端部を塞ぐ保持部により軸に回転可能に支持された回転子と、壁とは反対側の回転子の軸方向端部に設けられた綱車と、回転子の内周面に沿って放射状に配置されるとともに壁側の端部は回転子よりも壁側へ突出しており、穴と軸方向に対向できる位置に回転子に固定された複数の羽と、を備えたものである。 The elevator hoisting machine according to the present invention has a cylindrical frame body that is closed at one end side by a wall, opened at the other end side, and has a hole facing the other end side, and the other end from the wall. A shaft that protrudes to the side, an annular stator that is fixed to the inside of the frame body around the shaft, and has a hollow cylindrical shape. The outer peripheral surface is the first inner peripheral surface of the stator. The wall-side end face is opposed to the wall with a second gap and is positioned radially outward from the hole, and is rotated about the shaft by a holding part that closes the end opposite to the wall. A rotor that is supported, a sheave provided at an axial end of the rotor opposite to the wall, and a wall-side end arranged radially along the inner circumferential surface of the rotor Projects to the wall side of the rotor, and includes a plurality of wings fixed to the rotor at positions that can face the hole in the axial direction.

本発明によれば、エレベータ用巻上機を稼働すると綱車、回転子とともに羽が回転する。そして、回転子よりも壁側へ突出した羽に押された空気は遠心力により壁と回転子との間の第２の隙間の方へ流れ、更に固定子と回転子との間の第１の隙間の方へ流れて、巻上機の外へ排出される。このように空気が流れるのにともない枠体の外側の空気が壁の穴を通って枠体の内側へ流れ込んでくる。壁の穴は枠体の他端側に対向しており、つまり軸方向に開いているので空気は軸方向に流れ込んでくる。 According to the present invention, when the elevator hoist is operated, the wings rotate together with the sheave and the rotor. The air pushed by the wings protruding toward the wall from the rotor flows by the centrifugal force toward the second gap between the wall and the rotor, and further, the first between the stator and the rotor. It flows toward the gap and is discharged out of the hoist. As the air flows in this way, the air outside the frame body flows into the frame body through the hole in the wall. The hole in the wall faces the other end of the frame, that is, it opens in the axial direction, so air flows in the axial direction.

穴から流れ込んだ空気の一部は、穴と軸方向に対向できる位置に設けられた羽に押されて第２の隙間の方へ流れる。また、回転子の壁側端面は穴よりも径方向外側に位置しているため、つまり穴は回転子の内周側に対向しているため、軸心線方向に流れ込んだ空気の一部は、回転子の内周側へ流れ込む。回転子の内周側へ流れ込んだ空気は羽に押されて遠心力により回転子の内周面側へ流れる。壁とは反対側の回転子の端部は保持部により塞がれているので、内周面側へ流れた空気は壁側へ流れて来て第２の隙間の方へ流れて行く。そして、第１の隙間を通って巻上機の外へ排出される。この空気の流れにより巻上機を冷却するので、小型で簡単な冷却構造を有するエレベータ用巻上機を得ることができる。 A part of the air that has flowed from the hole is pushed by the wing provided at a position that can be opposed to the hole in the axial direction and flows toward the second gap. In addition, since the wall-side end surface of the rotor is located radially outward from the hole, that is, the hole faces the inner peripheral side of the rotor, a part of the air flowing in the axial direction is , Flows into the inner periphery of the rotor. The air flowing into the inner peripheral side of the rotor is pushed by the wings and flows toward the inner peripheral surface side of the rotor by centrifugal force. Since the end of the rotor opposite to the wall is closed by the holding part, the air flowing toward the inner peripheral surface flows toward the wall and flows toward the second gap. And it is discharged out of the hoist through the first gap. Since the hoisting machine is cooled by this air flow, an elevator hoisting machine having a small and simple cooling structure can be obtained.

本発明によれば、小型で簡単な冷却構造を有するエレベータ用巻上機を得ることができる。 According to the present invention, an elevator hoisting machine having a small and simple cooling structure can be obtained.

図１、図２、図３において、巻上機１には、枠体としてのハウジング２が設けられ、ハウジング２は筒状の本体３と、本体３の一端側を塞ぐ壁４とを有しており、本体３の他端側は開口されている。壁４には他端側へ突出するように軸５が設けられている。本体３の内周面にはコイル７ａが巻線された円環状の固定子７が固定されている。壁４には本体３の他端側に向かって貫通する８つの円形の穴１１が、軸５を中心とした円周上に並ぶように設けられている。 1, 2, and 3, the hoist 1 is provided with a housing 2 as a frame, and the housing 2 has a cylindrical main body 3 and a wall 4 that closes one end of the main body 3. The other end side of the main body 3 is opened. A shaft 5 is provided on the wall 4 so as to protrude to the other end side. An annular stator 7 around which a coil 7 a is wound is fixed to the inner peripheral surface of the main body 3. The wall 4 is provided with eight circular holes 11 penetrating toward the other end side of the main body 3 so as to be arranged on a circumference centering on the shaft 5.

軸５には一対の軸受９を介して中空円筒形状をした回転子１３が回転可能に支持されている。回転子１３は中空円筒形状のロータ１３aと、ロータ１３aの外周部に周方向に固定された複数の磁石１４と、壁４と反対側のロータ１３aの端部を塞ぐとともに軸受９に支持されてロータ１３aを保持する保持部１３ｂとを有している。ロータ１３aの壁４側は開口されている。 A rotor 13 having a hollow cylindrical shape is rotatably supported on the shaft 5 via a pair of bearings 9. The rotor 13 closes the end of the rotor 13a on the opposite side of the wall 4 and is supported by the bearing 9 while closing the hollow cylindrical rotor 13a, the plurality of magnets 14 fixed in the circumferential direction on the outer periphery of the rotor 13a. And a holding portion 13b for holding the rotor 13a. The wall 13 side of the rotor 13a is opened.

回転子１３の外周面を形成している磁石１４と固定子７の内周面との間には第１の隙間１５が開けられている。また、回転子１３の壁４側端面１３ｃと壁４との間には第２の隙間１７が開けられている。そして、回転子１３の壁４側端面１３ｃは、８つの穴１１よりもロータ１３aの径方向外側に位置するように設けられている。このため、回転子１３の壁４側端面１３ｃは、８つの穴１１に外接する円の外側に隣接する壁４ａの部分と第２の隙間１７を開けて対向している。そして、８つの穴１１は、回転子１３の内周側の中空部分と軸方向に対向している。 A first gap 15 is formed between the magnet 14 forming the outer peripheral surface of the rotor 13 and the inner peripheral surface of the stator 7. Further, a second gap 17 is formed between the wall 4 side end surface 13 c of the rotor 13 and the wall 4. The wall 4 side end surface 13 c of the rotor 13 is provided so as to be positioned on the radially outer side of the rotor 13 a with respect to the eight holes 11. For this reason, the wall 4 side end surface 13 c of the rotor 13 faces the portion of the wall 4 a adjacent to the outside of the circle circumscribing the eight holes 11 with the second gap 17 therebetween. The eight holes 11 face the hollow portion on the inner peripheral side of the rotor 13 in the axial direction.

壁４とは反対側の回転子１３の軸方向端部には綱車１９が設けられており、綱車１９は回転子１３と一体に回転する。綱車１９はハウジング２よりも軸方向に突出している。本体３の他端側の開口縁部にはカバー２１が設けられている。カバー２１の内周側はロータ１３aの外周面に対して第３の隙間２３を保ちながら沿うように設けられている。カバー２１により固定子７及び磁石１４はハウジング２の内側に覆い隠されている。綱車１９には乗りかご（図示せず）を懸架する主索（図示せず）が巻き掛けられている。 A sheave 19 is provided at the axial end of the rotor 13 opposite to the wall 4, and the sheave 19 rotates integrally with the rotor 13. The sheave 19 protrudes in the axial direction from the housing 2. A cover 21 is provided at the opening edge on the other end side of the main body 3. The inner peripheral side of the cover 21 is provided along the outer peripheral surface of the rotor 13a while maintaining the third gap 23. The cover 7 covers the stator 7 and the magnet 14 inside the housing 2. A main rope (not shown) for suspending a car (not shown) is wound around the sheave 19.

回転子１３の内周面に沿って放射状に複数の平板状の羽２５が配置されている。図４において、１枚の平板を折り曲げて１枚の羽２５とその羽２５の外周側に連なるつば部２７が形成されている。そして、つば部２７の部分が回転子１３の壁４側端面１３ｃにボルト２９により固定されている。羽２５は軸方向に垂直な仮想平面に対して傾斜するように回転子１３に配置されている。 A plurality of flat wings 25 are arranged radially along the inner peripheral surface of the rotor 13. In FIG. 4, a single flat plate is bent to form a single wing 25 and a collar portion 27 connected to the outer peripheral side of the wing 25. And the part of the collar part 27 is being fixed to the wall 4 side end surface 13c of the rotor 13 with the volt | bolt 29. FIG. The wings 25 are arranged on the rotor 13 so as to be inclined with respect to a virtual plane perpendicular to the axial direction.

羽２５の壁４側端部２５aは回転子１３よりも壁４の方へ突出されており、この壁４側端部２５aは第２の隙間１７の径方向内側に位置している。羽２５の保持部１３ｂ側端部２５ｂは保持部１３ｂに突き当たるところまで延ばされて設けられている。回転している羽２５が周方向に穴１１と同じ位置になったときに、羽２５は穴１１と軸方向に対向する位置に設けられている。そして、羽２５の外周側端部２５ｃは穴１１よりも径方向外側に設けられている。このため、羽２５の壁４側端部２５aは穴１１に対向するとともに穴１１の径方向外側に隣接している壁４aの部分とも対向している。羽２５の内周側端部２５ｄの径方向の位置は、穴１１が開けられている径方向の範囲内に設けられている。 The wall 4 side end 25 a of the wing 25 protrudes toward the wall 4 from the rotor 13, and the wall 4 side end 25 a is located on the radially inner side of the second gap 17. The holding part 13b side end part 25b of the wing 25 is provided to extend to a position where it comes into contact with the holding part 13b. When the rotating wing 25 is located at the same position as the hole 11 in the circumferential direction, the wing 25 is provided at a position facing the hole 11 in the axial direction. The outer peripheral side end 25 c of the wing 25 is provided on the radially outer side than the hole 11. For this reason, the wall 4 side end portion 25 a of the wing 25 faces the hole 11 and also opposes the portion of the wall 4 a adjacent to the radially outer side of the hole 11. The radial position of the inner peripheral end 25d of the wing 25 is provided within the radial range in which the hole 11 is formed.

このように構成されたエレベータ用巻上機１の冷却について説明する。コイル７ａに通電すると綱車１９、回転子１３とともに羽２５が回転する。また、通電にともない固定子７、回転子１３の温度が上昇する。回転子１３よりも壁４側に突出している羽２５で押された空気は遠心力により羽２５の径方向外側の第２の隙間１７の方へ空気が流れる。 The cooling of the elevator hoist 1 configured as described above will be described. When the coil 7 a is energized, the wings 25 rotate together with the sheave 19 and the rotor 13. Further, the temperature of the stator 7 and the rotor 13 increases with energization. The air pushed by the wings 25 projecting toward the wall 4 from the rotor 13 flows toward the second gap 17 on the radially outer side of the wings 25 by centrifugal force.

更に、空気は壁４に沿ってハウジング２の内周面に固定した固定子７の方へ流れる。ハウジング２は壁４により塞いでいるため風路としては行き止まりになるので、壁４沿いに流れて来た空気は向きを軸方向に変えて、固定子７の内周面と回転子１３の外周面の磁石１４の間の第１の隙間１５の方へ流れる。このように固定子７と回転子１３の間を壁４側から綱車１９側へ流れて来た空気は、カバー２１の内周面とロータ１３aの外周面との間の第３の隙間２３から巻上機１の外へ排出される。 Further, the air flows along the wall 4 toward the stator 7 fixed to the inner peripheral surface of the housing 2. Since the housing 2 is closed by the wall 4, it becomes a dead end as an air path. Therefore, the air flowing along the wall 4 changes its direction to the axial direction, and the inner peripheral surface of the stator 7 and the outer periphery of the rotor 13. It flows toward the first gap 15 between the surface magnets 14. Thus, the air flowing between the stator 7 and the rotor 13 from the wall 4 side to the sheave 19 side is the third gap 23 between the inner peripheral surface of the cover 21 and the outer peripheral surface of the rotor 13a. To the outside of the hoist 1.

羽２５で押した空気が遠心力で流れて行くのにともない、ハウジング２の外側の空気が穴１１を通ってハウジング２の内側へ流れ込んで来る。穴１１は本体３の他端側に向かって、つまり軸方向に貫通しているので、空気は軸方向に流れ込んで来る。流れ込んだ空気の一部は羽２５で押すことにより遠心力により第２の隙間１７の方へ流れて行く。 As the air pushed by the wings 25 flows by centrifugal force, the air outside the housing 2 flows into the inside of the housing 2 through the hole 11. Since the hole 11 penetrates toward the other end side of the main body 3, that is, in the axial direction, air flows in the axial direction. Part of the air that has flowed in is pushed toward the second gap 17 by the centrifugal force when pushed by the wings 25.

また、一部の空気は、そのまま軸方向に回転子１３の内周側まで流れて来る。そして、羽２５に押されて遠心力により回転子１３の内周面側へ流れる。壁４とは反対側の回転子１３の端部は保持部１３ｂにより塞がれており、羽２５は保持部１３ｂに突き当たるところまで延ばされて設けられているため、内周面側へ流れた空気は、内周面に沿って壁４側へ流れ、穴１１の径方向外側に隣接している壁４aの部分に突き当たる。そして、羽２５で押すことにより遠心力で第２の隙間１７の方へ流れて行く。その後、第１の隙間１５を通ってカバー２１の内周面とロータ１３aの外周面との間の第３の隙間２３から巻上機１の外へ排出される。 A part of the air flows in the axial direction to the inner peripheral side of the rotor 13 as it is. Then, it is pushed by the wing 25 and flows toward the inner peripheral surface of the rotor 13 by centrifugal force. The end of the rotor 13 opposite to the wall 4 is closed by the holding portion 13b, and the wings 25 are provided so as to extend so as to hit the holding portion 13b. The air flows along the inner peripheral surface toward the wall 4 and hits the portion of the wall 4a adjacent to the outside of the hole 11 in the radial direction. Then, when it is pushed by the wing 25, it flows toward the second gap 17 by centrifugal force. Thereafter, the air is discharged out of the hoisting machine 1 from the third gap 23 between the inner peripheral surface of the cover 21 and the outer peripheral surface of the rotor 13 a through the first gap 15.

また、羽２５を軸方向に垂直な仮想平面に対して傾斜して設けているので、エレベータの昇降にともない回転子１３の回転方向が逆転することによって、回転子１３の内周側へ流れ込んだ空気を攪拌し回転子１３の内周に空気を行き渡らせる。 Further, since the wings 25 are provided so as to be inclined with respect to a virtual plane perpendicular to the axial direction, the rotation direction of the rotor 13 is reversed as the elevator moves up and down, so that it flows into the inner peripheral side of the rotor 13. The air is agitated to spread the air around the inner periphery of the rotor 13.

このように回転子１３の内周面に沿って配置した羽２５により、穴１１から巻上機１の内側に空気を取入れ、回転子１３及び固定子７と接触させながら流した後に、綱車１９側から巻上機１の外へ排出する。この過程で回転子１３及び固定子７の熱を空気へ伝えて空気とともに巻上機１の外へ排出して巻上機１を冷却するので、小型で簡単な冷却構造を有するエレベータ用巻上機を得ることができる。 After the air is taken into the hoisting machine 1 from the hole 11 by the wings 25 arranged along the inner peripheral surface of the rotor 13 in this manner and flows while being in contact with the rotor 13 and the stator 7, the sheave It discharges from the winding machine 1 from 19 side. In this process, the heat of the rotor 13 and the stator 7 is transferred to the air and discharged together with the air to the outside of the hoisting machine 1 to cool the hoisting machine 1, so that the hoisting for an elevator having a small and simple cooling structure is provided. You can get a chance.

また、空気を取入れる穴１１は、回転子１３の内周面に沿って放射状に配置される羽２５と軸方向に対向しているので、空気を回転子１３の内周側に効率良く取入れることができる。そして、空気を取入れる穴１１は、回転子１３の内周側の中空部分と軸方向に対向しているので、穴１１からハウジング２の内側へ流れ込んできた空気の多くは回転子１３の内周側に流れた後、回転子１３の外周側である第１の隙間１５を通って排出されるので回転子１３を充分に冷却できる。 Further, since the hole 11 for taking in air faces the wings 25 arranged radially along the inner peripheral surface of the rotor 13 in the axial direction, the air is efficiently taken into the inner peripheral side of the rotor 13. Can be put. Since the hole 11 for taking in air faces the hollow portion on the inner peripheral side of the rotor 13 in the axial direction, most of the air that has flowed into the housing 2 from the hole 11 is inside the rotor 13. After flowing to the circumferential side, it is discharged through the first gap 15 on the outer circumferential side of the rotor 13, so that the rotor 13 can be sufficiently cooled.

さらに、羽２５を回転子１３の保持部１３ｂまで延ばして設けており、また、軸方向に垂直な仮想平面に対して傾斜して設けているので、エレベータの昇降にともない回転子１３の回転方向が逆転することによって、内周側へ流れた空気を攪拌し回転子１３の内周に空気を行き渡らせて回転子１３を充分に冷却できる。 Further, since the wings 25 are provided to extend to the holding portion 13b of the rotor 13 and are inclined with respect to a virtual plane perpendicular to the axial direction, the rotation direction of the rotor 13 as the elevator moves up and down. Is reversed, the air flowing toward the inner peripheral side is agitated, and the air is spread around the inner periphery of the rotor 13 so that the rotor 13 can be sufficiently cooled.

また、羽２５の外周側端部２５ｃは穴１１よりも径方向外側に設けられ、羽２５の壁４側端部２５aは穴１１の径方向外側に隣接している壁４aの部分と対向するようにしているので、回転子１３の内周面に沿って壁４側へ流れる空気は、ハウジング２の外側から内側へ流れ込んで来る空気と衝突することなく壁４側へ流れることができる。 Further, the outer peripheral side end portion 25 c of the wing 25 is provided on the radially outer side than the hole 11, and the wall 4 side end portion 25 a of the wing 25 faces the portion of the wall 4 a adjacent to the radially outer side of the hole 11. Thus, the air flowing toward the wall 4 along the inner peripheral surface of the rotor 13 can flow toward the wall 4 without colliding with the air flowing in from the outside of the housing 2 to the inside.

また、羽２５の内周側端部２５ｄの径方向の位置は、穴１１が開けられている径方向の範囲内に設けられているため、ハウジング２の外側から内側へ流れ込み、次に回転子１３の内周面側へ流れるという空気の経路が形成され効率良く冷却できる。 Further, since the radial position of the inner peripheral side end portion 25d of the wing 25 is provided within the radial range in which the hole 11 is formed, it flows from the outside to the inside of the housing 2, and then the rotor. The air path of flowing to the inner peripheral surface side of 13 is formed and can be cooled efficiently.

なお、本実施の形態では、羽２５を軸方向に垂直な仮想平面に対して傾斜して設けた場合で説明したが、仮想平面に対して垂直に設けてもよい。また、穴１１は円形にしているが、穴の形状は円形に限定されるものではなく、例えば楕円や長方形であってもよい。 In the present embodiment, the case where the wings 25 are provided to be inclined with respect to the virtual plane perpendicular to the axial direction has been described. However, the wings 25 may be provided perpendicular to the virtual plane. Moreover, although the hole 11 is circular, the shape of the hole is not limited to a circle, and may be, for example, an ellipse or a rectangle.
