Description

本発明は、エレベータの運行を駆動する牽引装置の構造に関するものであり、エレベータの技術分野に属する。   The present invention relates to a structure of a traction device that drives operation of an elevator, and belongs to the technical field of elevators.

牽引機はエレベータ設備のコアとして、其の性能と取り付けの質はエレベータの性能に直接な影響を与えるため、エレベータのユーザは牽引機の配置と取り付けを重要視している。現在のエレベータに利用されている無歯車牽引装置は、交流非同期式にせよ、永久磁石同期式にせよ、全てはカンチレバー式、ブリッジ式またはスリーポイント式である。カンチレバー式牽引機は、牽引車輪のカンチレバーをトラクション・モーターの軸に取り付けることにより、エレベータの重量の100％を電動機が受ける仕組みである。ブリッジ式またはスリーポイント式牽引機は、その牽引車輪をブリッジのようにトラクション・モーターと軸受けブラケットとの間に取り付けることにより、エレベータ設備の重量の50％をトラクション・モーターが受ける仕組みである。   As the traction machine is the core of the elevator installation, its performance and installation quality directly affect the performance of the elevator, so elevator users place great importance on the arrangement and installation of the traction machine. The gearless traction devices used in current elevators are of the cantilever type, the bridge type or the three-point type, regardless of whether they are an AC asynchronous type or a permanent magnet synchronous type. The cantilever tractor is a mechanism in which the electric motor receives 100% of the weight of the elevator by attaching the cantilever of the traction wheel to the shaft of the traction motor. The bridge type or three point type tractor is a mechanism in which the traction motor receives 50% of the weight of the elevator equipment by attaching the traction wheel between the traction motor and the bearing bracket like a bridge.

永久磁石同期電動機の回転子と固定子との間には、隙間はわずかの0.7mmである。何トンもするエレベータの重量とカーやウェートの下方の無視できないワイヤロープの引っ張り強さを薄型永久磁石電動機が受けると、電動機回転子と固定子との間の隙間が変えられるため、エレベータの運行に影響を与え、牽引機の運行の質が下がり、ひいてはパワーが下がることもある。このような場合、問題のある牽引機については、重荷と無ロードの状況では機械と電磁の運行雑音は数倍も異なり、電動機の発熱も起きる。重荷をうける無歯車牽引機が原因でエレベータは運行時に震えさえもする。牽引機の使用期間も縮減する。(特許文献1及び2)
中国実用新案特許第200320120164.5(公開番号CN2666874) 中国発明特許出願第200410085306.8(公開番号CN1644480) The gap between the rotor and the stator of the permanent magnet synchronous motor is only 0.7 mm. When the thin permanent magnet motor receives the weight of an elevator that takes many tons and the tensile strength of a wire rope below the car or weight, the gap between the motor rotor and stator can be changed, so elevator operation The quality of the tractor's operation may be reduced and the power may be reduced. In such a case, the troubled traction machine has several times different noise between the machine and electromagnetic operation under heavy load and no load, and the motor generates heat. Due to the gearless traction machine that is under heavy load, the elevators even tremble during operation. The period of use of the traction machine is also reduced. (Patent Documents 1 and 2)

本発明は既存エレベータ牽引装置の上述短所を克服し、安定した運行で、長期間使用できる無軸負載式無歯車牽引装置を提供することを目的とする。   An object of the present invention is to overcome the above-described disadvantages of existing elevator traction devices and to provide a non-shaft-mounted gearless traction device that can be used for a long time with stable operation.

本発明の目的は以下のように実現される。底ベース及び底ベースに取り付けられる軸受けブラケット、トラクション・モーターと牽引車輪を有する無軸負載式無歯車牽引装置において、前記牽引装置にはエレベータの総重量を受ける荷重量の主軸と二つの軸受けブラケットが設けられ、牽引車輪が荷重量の主軸を通じて二つの軸受けブラケットの間に取り付けられ、トラクション・モーターが軸受けブラケットの外側の荷重量の主軸の軸ヘッドに取り付けられ、トラクション・モーターの底部と底ベースの間にたわみ継手が設けられることを特徴とする無軸負載式無歯車牽引装置。   The object of the present invention is realized as follows. A bottom base and a bearing bracket attached to the bottom base, a non-shaft negative-type gearless traction device having a traction motor and a traction wheel, wherein the traction device includes a main shaft having a load amount that receives the total weight of the elevator and two bearing brackets. Provided, the traction wheel is mounted between the two bearing brackets through the load spindle, the traction motor is mounted on the spindle head of the load spindle outside the bearing bracket, the bottom and bottom base of the traction motor A non-axial negative-type gearless traction device, characterized in that a flexible joint is provided therebetween.

前記たわみ継手はクッション、圧力調整螺子及びジョイントベースから構成され、ジョイントベースが底ベースに固定連結し、クッションはジョイントベースの中に設けられ、クッションのトップに圧力調整螺子を取り付け、圧力調整螺子をトラクション・モーターの底部の取り付けホールにはめる。圧力螺子を調整する時、圧力センサーを通じて、最終にトラクション・モーターの全部重量が荷重量の主軸の軸ヘッドで“０”に表示されるまで調整される。   The flexible joint is composed of a cushion, a pressure adjusting screw, and a joint base. The joint base is fixedly connected to the bottom base, the cushion is provided in the joint base, the pressure adjusting screw is attached to the top of the cushion, and the pressure adjusting screw is attached. Fit into the mounting hole at the bottom of the traction motor. When adjusting the pressure screw, it is adjusted through the pressure sensor until the total weight of the traction motor is finally displayed as "0" on the spindle head of the load spindle.

専用ブロックが前記クッションに取って代わることができる。トラクション・モーターが前記たわみ継手で支えられる。前記圧力調整螺子の位置は、前記トラクション・モーターのセンターラインと前記荷重量の主軸の中心が共線にある位置である。   A dedicated block can replace the cushion. A traction motor is supported by the flexible joint. The position of the pressure adjusting screw is a position where the center line of the traction motor and the center of the main axis of the load amount are collinear.

本発明の装置は、構造が合理的で簡単であるため、製造しやすく、コストが低く、性能が安定しており、雑音が無く、使用期間が長い。牽引車輪はロードを受けると、そのロードを左右の二つの軸受けブラケットに伝え、トラクション・モーターの底部はたわみ継手を取りつけるため、エレベータからのウェートを受けず、牽引車輪のロードはトラクション・モーターに影響を与えない。トラクション・モーターは動力を提供するだけで、エレベータの重量は牽引車輪の左右の軸受けブラケットによって受けられるため、完全にロードを受けた後でも牽引機が最高の力率と無雑音を確保できる。   The device of the present invention has a reasonable structure and is easy to manufacture, has a low cost, has a stable performance, is free from noise, and has a long service life. When the traction wheel receives a load, it transmits the load to the two left and right bearing brackets, and the bottom of the traction motor attaches a flexible joint, so it does not receive any weight from the elevator, and the load on the traction wheel affects the traction motor. Not give. The traction motor only provides power, and the weight of the elevator is received by the left and right bearing brackets on the traction wheel, ensuring that the traction machine has the highest power factor and no noise even after it is fully loaded.

本発明は軸ロードのない新型無歯車牽引機で、エレベータの重量を受ける牽引車輪を一つの重量受け荷重量の主軸を通じて、二つの軸受けブラケットで該主軸をかけて、薄型トラクション・モーターを該主軸の一端の軸ヘッドに取り付けたと同時に、トラクション・モーターの底部の両側にクッションを1セットずつ設置し、調整する時、圧力センサーを通じて調整や位置定めを行い、トラクション・モーターの全部重量を受けるために、クッションのトップに調整可能な圧力調整螺子を一つずつ設け、トラクション・モーターがクッションと圧力調整螺子からなるたわみ継手ベースの上に浮遊する。トラクション・モーター内の二つの軸受けは軽ロードまたは無ロードで運行するため、トラクション・モーターの軸受けがよりよく回転し、永久磁石同期牽引機も各種の不規則な受力を避けるができるため、トラクション・モーターの回転子と固定子の隙間は何の変化もせず、先に設計された理想の隙間に回転するため、雑音を回避でき、電動機の力率も大いに増加できる。それと同時に、その牽引装置はロード数と速度を持続可能で増加することができる。エレベータの速度とロード数を増加する必要があれば、荷重量の主軸のほかの一端でもう一つのトラクション・モーターを取り付け、同期運行し、牽引車輪の大きさを調整することで、大型エレベータと高速エレベータに対する需要を実現することができる。この牽引装置はユーザに人気があり、高い応用価値と広い市場の見通しがある。   The present invention is a new gearless traction machine without a shaft load, in which a traction wheel that receives the weight of an elevator passes through the main shaft of one weight receiving load amount, the main shaft is mounted by two bearing brackets, and a thin traction motor is connected to the main shaft. In order to receive the full weight of the traction motor by adjusting and positioning through the pressure sensor when installing and adjusting one set of cushions on both sides of the bottom of the traction motor at the same time as attaching to the shaft head at one end of the Each adjustable pressure adjustment screw is provided on the top of the cushion, and the traction motor floats on the flexible joint base composed of the cushion and the pressure adjustment screw. Because the two bearings in the traction motor operate with light or no load, the traction motor bearings rotate better, and the permanent magnet synchronous traction machine can also avoid various irregular receiving forces. -The gap between the rotor and stator of the motor does not change and rotates to the ideal gap designed earlier, so noise can be avoided and the power factor of the motor can be greatly increased. At the same time, the traction device can sustainably increase the load number and speed. If it is necessary to increase the speed and number of loads of the elevator, install another traction motor at the other end of the main spindle of the load amount, operate it synchronously, and adjust the size of the towing wheel. Demand for high speed elevators can be realized. This traction device is popular with users and has high application value and broad market prospects.
