Description

电梯用卷扬机Hoist for elevator

技术领域technical field

本发明涉及使电梯的乘用轿厢升降的电梯用卷扬机。The present invention relates to an elevator hoist for raising and lowering a passenger car of an elevator.

背景技术Background technique

在以往的电梯用卷扬机中，有如下结构：在将直径比宽度大的薄型扁平无刷直流电机配置在升降通道内的电梯装置中，电机是定子与转子的间隙位于径向的径向间隙型，通过进行将所有的定子线圈不横跨在2个极齿上以卷绕在1个极齿的周围的所谓集中卷绕，能使线圈端的伸出减小而作成薄型(例如，参照专利文献1)。In conventional hoists for elevators, there is a structure in which a thin flat brushless DC motor with a larger diameter than width is arranged in the hoistway, and the motor is a radial gap type in which the gap between the stator and the rotor is located in the radial direction. , by performing so-called concentrated winding in which all the stator coils are wound around one pole tooth without straddling two pole teeth, the protrusion of the coil end can be reduced and made thin (for example, refer to the patent document 1).

另外，作为其它的电梯用卷扬机，例如，已知有专利文献2～4等。In addition, as other hoisting machines for elevators, for example, Patent Documents 2 to 4 and the like are known.

[专利文献2]日本专利特开平9-142761号公报[Patent Document 2] Japanese Patent Laid-Open No. 9-142761

[专利文献3]日本专利特开2000-302360号公报[Patent Document 3] Japanese Patent Laid-Open No. 2000-302360

[专利文献4]日本专利特开平1-187187号公报[Patent Document 4] Japanese Patent Laid-Open No. 1-187187

专利文献1记载的卷扬机是，为了抑制作为集中卷绕电机的缺点的转矩脉动而必须将极数增加，但这样做由于驱动频率增高，故难以控制且容易发生噪音。另外，专利文献2记载的卷扬机是薄型大直径的，在卷扬机轴向长度中线圈端长度占有的比例增大，铜损也增大。另外，专利文献3、4记载的卷扬机，由于是将外转子型电机内藏在绳轮的内侧的方式，故若所需转矩被确定，在通常的电机中效率和温度上升，为了维持其它转矩特性，大致取决于电机直径的平方及其长度，当将电机配置在绳轮内侧时，实际上存在电机长度比卷挂有绳索的绳槽部的宽度要长的问题。In the hoisting machine described in Patent Document 1, the number of poles must be increased in order to suppress torque ripple, which is a disadvantage of the concentrated winding motor, but this increases the driving frequency, making it difficult to control and prone to noise. In addition, the hoist described in Patent Document 2 is thin and large in diameter, and the ratio of the length of the coil end to the axial length of the hoist increases, and the copper loss also increases. In addition, since the hoisting machine described in Patent Documents 3 and 4 has an outer rotor type motor built inside the sheave, if the required torque is determined, the efficiency and temperature of the normal motor will increase. In order to maintain other Torque characteristics roughly depend on the square of the diameter of the motor and its length. When the motor is arranged inside the sheave, there is actually a problem that the length of the motor is longer than the width of the rope groove where the rope is wound.

图中，本发明的电梯用卷扬机结构是具有：在基座1上分别留有间隔地立设固定在两侧上的作为卷扬机固定部的轴承座壳体2；固定在该各轴承座壳体2中央部上的轴承3；两端部旋转自如地支承在该各轴承3上的旋转轴4；设在该旋转轴4中央部的轮毂部5；通过放射状设在该轮毂部5的外侧的轮辐6而被支承的构成第2转子的内侧环状体7；通过放射状设在该内侧环状体7的外侧且正面看为骨架状(臼状)的轮辐8而被支承的由构成第1转子的外侧环状体构成的绳轮9；形成在该绳轮9外周面上、卷挂着主索(未图示)的绳槽9a；分别固定在该绳轮9的轴向两端部上、其外方周端部成为制动面10a的制动圆盘10；安装在上述轴承座壳体2的外周端部外方内侧面上、设有与制动面10a相对的制动瓦11a的制动装置11；分别设在上述绳轮9的内周面的两端部和内侧环状体7外周面两端部上的转子磁铁12；以及外方端部分别固定在上述轴承座壳体2的外周部内侧面上、内方端部被收容在位于上述绳轮9与内侧环状体7之间的骨架状(臼状)轮辐8的两侧部的凹部中、且被配置在上述转子磁铁12间的螺旋管形绕组电机的定子13。另外，图中，14是安装在旋转轴4的一端部的编码器，15是编码器安装座。In the figure, the elevator winch structure of the present invention is to have: on the base 1, respectively leave interval ground and be fixed on the bearing block housing 2 as the winch fixing part on both sides; 2 the bearing 3 on the central part; the rotating shaft 4 rotatably supported on each bearing 3 at both ends; the hub part 5 provided at the central part of the rotating shaft 4; The inner annular body 7 that constitutes the second rotor supported by the spokes 6; the inner annular body 7 that is radially arranged on the outer side of the inner annular body 7 and that is supported by the spokes 8 that are skeleton-shaped (mortar-shaped) when viewed from the front constitutes the first rotor. The sheave 9 formed by the outer annular body of the rotor; the sheave 9a formed on the outer peripheral surface of the sheave 9, and the main rope (not shown) is wound around; fixed to both axial ends of the sheave 9 respectively On the top, its outer peripheral end becomes the brake disc 10 of the braking surface 10a; it is installed on the outer inner surface of the outer peripheral end of the above-mentioned bearing housing 2, and is provided with a brake shoe opposite to the braking surface 10a. The brake device 11 of 11a; the rotor magnets 12 respectively arranged on the two ends of the inner peripheral surface of the above-mentioned sheave 9 and the two ends of the outer peripheral surface of the inner annular body 7; and the outer ends are respectively fixed on the above-mentioned bearing housings On the inner surface of the outer peripheral portion of the housing 2, the inner end is accommodated in the recesses on both sides of the skeleton-shaped (mortise-shaped) spoke 8 between the above-mentioned sheave 9 and the inner annular body 7, and is arranged in the The stator 13 of the toroidal winding motor between the above-mentioned rotor magnets 12 . In addition, in the figure, 14 is an encoder attached to one end of the rotary shaft 4, and 15 is an encoder mounting base.

上述螺旋管形绕组电机的定子13，具有图2所示结构的螺旋管形绕组13a，由于将漆包线卷绕在定子铁心上，故线圈端可以作成短的结构。因此，由于无一般的集中卷绕电机那样、对极数和槽数的组合的相当限制，故能容易确保高性能。并且，在定子的内周侧和外周侧分别配置着转子磁铁12，由于在内外两侧的间隙中发生驱动转矩，故与以往的仅单侧的情况相比，对于相同直径的通常的电机，能以相同的效率将轴向长度作成大约一半。另外，若将由第1和第2转子构成的2个转子的相位差适当地错开，则能将分别发生的转矩脉动消除而作成低转矩脉动。The stator 13 of the above-mentioned toroidal winding motor has a toroidal winding 13a of the structure shown in FIG. 2. Since the enameled wire is wound on the stator core, the coil end can be made into a short structure. Therefore, since there is no considerable restriction on the combination of the number of poles and the number of slots like in a general concentrated winding motor, high performance can be easily ensured. In addition, rotor magnets 12 are arranged on the inner and outer peripheral sides of the stator, and since the driving torque is generated in the gap between the inner and outer sides, compared with the conventional case of only one side, the same diameter of the normal motor , the axial length can be made approximately half with the same efficiency. In addition, if the phase difference between the two rotors constituted by the first and second rotors is properly shifted, the torque ripples that occur respectively can be eliminated and low torque ripples can be created.

在通常的电机中，要将电机配置在绳轮的内侧，现实中有困难，而若采用螺旋管形绕组电机的定子13，由于具有上述那样的特点，故其比较容易。如图1所示，由于将绳轮9内部的结构物尽量缩小，故能将定子和转子磁铁配置在该部分。定子是被安装在作为卷扬机固定部的2个轴承座壳体2上、其轴向进入绳轮9的内部的结构。另外，是将在定子的内周侧和外周侧上构成磁场磁极的永久磁铁配置在分别构成第1转子的绳轮9内周侧两端部和构成第2转子的内侧环状体7外周侧的两端部的结构。螺旋管形绕组电机的定子13合计为2个，由于是分别在内周侧和外周侧上与2个磁场磁极对应的结构，故利用位置关系及接线方法等、即作为各2转子的双电机，能获得高性能多功能的结构。另外，将制动圆盘10两片安装在绳轮9的轴向两端部，由于将制动器分散配置，故各个制动器成为小型的结构，能减小卷扬机的外径。In a common motor, it is difficult to arrange the motor inside the sheave, but if the stator 13 of the toroidal winding motor is used, it is relatively easy due to the above-mentioned characteristics. As shown in FIG. 1, since the structure inside the sheave 9 is made as small as possible, the stator and rotor magnets can be arranged in this part. The stator is attached to the two bearing housings 2 as the hoisting machine fixing portion, and has a structure in which the axial direction enters the inside of the sheave 9 . In addition, the permanent magnets constituting the magnetic field poles on the inner peripheral side and the outer peripheral side of the stator are disposed on both ends of the inner peripheral side of the sheave 9 constituting the first rotor and on the outer peripheral side of the inner annular body 7 constituting the second rotor, respectively. structure at both ends. The total number of stators 13 of the toroidal winding motor is two, and since the inner peripheral side and the outer peripheral side respectively correspond to the two magnetic field poles, the positional relationship and wiring method, etc., are used as a double motor with two rotors each. , can obtain a high-performance multifunctional structure. In addition, two brake discs 10 are mounted on both ends of the sheave 9 in the axial direction, and since the brakes are distributed, each brake has a compact structure, and the outer diameter of the hoist can be reduced.

The structure is to have: the back panel 16 fixed on the base (not shown) as the fixed part of the hoist; the main shaft 17 fixed on the central part of one side of the back panel 16; The bearing 3; the inner annular body 7 rotatably supported by the bearing 3; the sheave 9 composed of the outer annular body integrally supported on the outer side of the inner annular body 7; The rope groove 9a that is formed on the outer peripheral surface; Be fixed on the end portion on the opposite side of this sheave 9 back plate 16, its outer peripheral end portion becomes the braking disk 10 of braking surface 10a; Be provided with and brake The brake device 11 of the brake shoe 11a opposite to the surface 10a; the rotor 18 respectively arranged on the inner peripheral surface of the above-mentioned sheave 9 and the outer peripheral surface of the inner annular body 7; and the outer end is fixed on the above-mentioned back plate 16 is housed in the concave portion formed between the sheave 9 and the inner annular body 7 and is disposed between the rotors 18 of the stator 13 of the toroidal winding motor. In addition, in the figure, 14 is an encoder attached to one end of the main shaft 4 .

因此，本发明实施形态2的电梯用卷扬机，能适用于以单臂结构可承受仅施加轴负荷的电机。另外，除上述以外，是与实施形态1中的动作、效果大致相同。Therefore, the hoisting machine for an elevator according to Embodiment 2 of the present invention can be applied to a motor capable of receiving only an axial load with a single-arm structure. In addition, except for the above, the operation and effect are substantially the same as those in the first embodiment.
