Description

一种带磁齿轮减速器的全封闭力矩电机A fully enclosed torque motor with magnetic gear reducer

技术领域technical field

本实用新型属于低速大转矩电机领域,更具体地,涉及一种带磁齿轮减速器的全封闭力矩电机。The utility model belongs to the field of low-speed high-torque motors, and more particularly relates to a fully enclosed torque motor with a magnetic gear reducer.

背景技术Background technique

随着油田开发的逐步深入,原油的开采中需要耐高温、高压且密封性好的电机。由于油井细长的特征,井下电机的设计尺寸也应该更为细长。但现有的高温电机仍然采用行星齿轮减速机构的驱动方案,由于此方案依靠齿轮间的啮合达到减速目的,故存在承载能力差、可靠性差等问题。With the gradual deepening of oilfield development, high temperature, high pressure and good sealing motors are required in crude oil extraction. Due to the slender characteristics of oil wells, the design size of downhole motors should also be more slender. However, the existing high-temperature motor still adopts the drive scheme of the planetary gear reduction mechanism. Since this scheme relies on the meshing between the gears to achieve the purpose of deceleration, there are problems such as poor bearing capacity and poor reliability.

中国实用新型专利《一种电动潜油螺杆泵机组及其减速器》(公开号:CN208890621U,公开日:2019.05.21)中公开了一种磁齿轮减速结构。该磁齿轮包括内转子,外转子和外壳。在外定子上具有若干个沿其周向间隔设置的导磁材料,外壳包括设设置在其内壁上沿周向间隔布置的若干个壳永磁体,内转子包括在其外周面上沿周向间隔布置的若干个内永磁体,壳永磁体的数量大于内永磁体的数量,相邻的两个壳永磁体和相邻的两个内永磁体径向充磁方向相反。The Chinese utility model patent "An Electric Submersible Screw Pump Unit and its Reducer" (publication number: CN208890621U, publication date: 2019.05.21) discloses a magnetic gear deceleration structure. The magnetic gear includes an inner rotor, an outer rotor and a casing. The outer stator has a plurality of magnetically conductive materials spaced along its circumference, the outer casing includes a plurality of shell permanent magnets arranged on its inner wall and arranged at a circumferential interval, and the inner rotor includes a circumferentially spaced arrangement on its outer peripheral surface. There are several inner permanent magnets, the number of shell permanent magnets is greater than the number of inner permanent magnets, and the radial magnetization directions of two adjacent shell permanent magnets and two adjacent inner permanent magnets are opposite.

上述的磁齿轮减速器设计从外到内依次是外壳、外转子、内转子,当内转子转动时,通过外转子上导磁材料的调制作用内层气隙会产生一个旋转磁场耦合而带动外转子转动,根据设置永磁极对数的比值,能够实现减速的功能。这种结构采用无接触传动,减少了机械损耗,降低了热损耗。The above-mentioned magnetic gear reducer is designed to be the outer casing, the outer rotor, and the inner rotor in sequence from the outside to the inside. When the inner rotor rotates, the inner air gap will generate a rotating magnetic field coupling through the modulation of the magnetic conductive material on the outer rotor to drive the outer rotor. The rotor rotates, and the function of deceleration can be realized according to the ratio of the number of permanent magnet pole pairs. This structure adopts non-contact transmission, which reduces mechanical loss and heat loss.

但是,这种结构存在本身难以克服的缺陷。首先,这种结构仍然存在三层结构,两层间隙,结构的设计较为复杂,且由于内转子、外转子及外壳的直径较小,永磁体及铁芯难以安装,且安装的数量较少,难以达到更高范围的减速传动比。不仅如此,当电机处于静止状态时,外壳与内转子上的永磁体会产生径向作用力从而影响外壳和内转子的受力,由于设计的外壳本身较薄,会降低外壳的寿命;其次,这种电机对于井下气液固分子共存的环境,不具有良好的密封性,并且井下堵转转矩要求高,长时间无法启动易造成堵转电流过大导致温度过高影响电机寿命甚至烧毁电机的情况。However, this structure has its own insurmountable defects. First of all, this structure still has a three-layer structure and two-layer gap, and the design of the structure is relatively complicated, and due to the small diameters of the inner rotor, outer rotor and outer casing, it is difficult to install permanent magnets and iron cores, and the number of installations is small. It is difficult to achieve higher range reduction gear ratios. Not only that, when the motor is in a static state, the permanent magnets on the outer casing and the inner rotor will generate radial force, which will affect the force on the outer casing and the inner rotor. Because the designed casing itself is thin, the life of the casing will be reduced; secondly, This kind of motor does not have good sealing performance for the environment where gas, liquid and solid molecules coexist in the well, and the downhole locked-rotor torque has high requirements. If it cannot be started for a long time, it is easy to cause the locked-rotor current to be too large and the temperature to be too high, which affects the life of the motor and even burns the motor. Case.

In addition, it also includes a rotor bearing 14, a disc-shaped structure bearing 11 on the rear side of the rotor shaft, and an output shaft bearing 16, which are used to support the rotating shaft of the motor and make the motor rotate smoothly.

进一步地,第二级输出转子具有盘状结构5与输出轴;第二级输出转子盘状结构5表面贴有轴向充磁永磁体8,相邻两个永磁体的充磁方向相反。Further, the second-stage output rotor has a disk-shaped structure 5 and an output shaft; the surface of the second-stage output rotor disk-shaped structure 5 is affixed with axially magnetized permanent magnets 8, and the magnetization directions of two adjacent permanent magnets are opposite.

进一步地,调磁盘4主体由不导磁材料构成,中间嵌有沿圆周分布的调磁铁芯7。Further, the main body of the adjusting disk 4 is made of non-magnetic material, and the adjusting magnetic core 7 distributed along the circumference is embedded in the middle.

进一步地,游标电机的定子槽数m与电枢绕组极对数n之和等于转子表贴永磁体极对数p。转子轴后侧盘状结构表贴永磁体极对数j与所述第二级输出转子盘状结构表贴永磁体极对数k之和等于调磁盘的调磁铁芯数。在本具体实施例中,包括6槽10极游标电机及转子轴表贴永磁体极对数,第二级输出转子表贴永磁体极对数,调磁盘导磁铁芯数分别为2,6,8的磁齿轮加速器。Further, the sum of the number of stator slots m of the vernier motor and the number of pole pairs n of the armature winding is equal to the number of pole pairs p of the permanent magnets on the rotor surface. The sum of the number of pole pairs j of the surface-mounted permanent magnets on the disk-shaped structure on the rear side of the rotor shaft and the number k of the surface-mounted permanent magnets on the disk-shaped structure of the second-stage output rotor is equal to the number of tunable magnet cores of the tunable magnetic disk. In this specific embodiment, it includes a 6-slot 10-pole vernier motor and the number of pole pairs of permanent magnets attached to the rotor shaft, the number of pole pairs of permanent magnets attached to the surface of the second-stage output rotor, and the number of magnetic cores of the adjusting disk are 2 and 6, respectively. 8's magnetic gear accelerator.

该电机的的外壳直径为25mm,电机及减速器的总长度为90mm。其中游标电机轴向长度为65mm,磁齿轮减速器为25mm。The housing diameter of the motor is 25mm, and the total length of the motor and the reducer is 90mm. The axial length of the vernier motor is 65mm, and the magnetic gear reducer is 25mm.

电机主体部分通有三相交流电流,电枢线圈极对数为1。由于三相交流电产生的旋转的磁通作用在气隙中,在转子部分产生了旋转的磁通,进而产生旋转力矩,与转子轴上的贴片永磁体作用,产生一定转速的内转子,实现了第一级转矩的产生,该转矩具有较高的转速和较高的转矩。与转子轴相连的转子后侧盘状结构将第一级产生旋转的转子传动转矩至磁齿轮减速器时,由于其表贴永磁体沿圆周分布的结构,在后侧产生旋转的磁场,该磁场旋转的谐波极对数为2。该谐波作用在调磁铁芯数为8调磁盘上,经过调磁盘的调制,于第二级输出转子相连的盘状结构处产生谐波极对数为6的旋转的磁场与其表贴的极对数为6对的永磁体,产生该情况下最大的转矩和最小的转速。产生对应的转动力矩作用于外转子的永磁体上,产生旋转。此时减速器实现了变比为3:1的减速比。该转矩具有低转速,高转矩的特点。除此之外,改变调磁盘上调磁铁芯的极对数及两侧盘状结构上贴片永磁体极对数,可以任意调节减速比。The main part of the motor is supplied with three-phase alternating current, and the number of pole pairs of the armature coil is 1. Because the rotating magnetic flux generated by the three-phase alternating current acts on the air gap, a rotating magnetic flux is generated in the rotor part, and then a rotating torque is generated, which interacts with the patch permanent magnets on the rotor shaft to generate an inner rotor with a certain speed. The first stage torque is generated, which has higher rotational speed and higher torque. When the disc-shaped structure on the rear side of the rotor connected to the rotor shaft transmits the rotating rotor generated by the first stage to the magnetic gear reducer, a rotating magnetic field is generated on the rear side due to the structure of the surface-mounted permanent magnets distributed along the circumference. The number of harmonic pole pairs of magnetic field rotation is 2. The harmonics act on the tunable magnetic disk with 8 cores. After the modulation of the tunable magnetic disk, a rotating magnetic field with 6 harmonic pole pairs is generated at the disk-shaped structure connected to the second-stage output rotor and the poles attached to its surface. The logarithm of 6 pairs of permanent magnets produces the maximum torque and minimum rotational speed in this case. A corresponding rotational moment is generated to act on the permanent magnets of the outer rotor to generate rotation. At this time, the reducer achieves a reduction ratio of 3:1. The torque has the characteristics of low speed and high torque. In addition, the reduction ratio can be adjusted arbitrarily by changing the number of pole pairs of the magnetic core on the magnetic disk and the number of pole pairs of the permanent magnets on the disk-shaped structure on both sides.

本领域的技术人员容易理解,以上所述仅为本实用新型的较佳实施例而已,并不用以限制本实用新型,凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本实用新型的保护范围之内。Those skilled in the art can easily understand that the above are only preferred embodiments of the present invention, and are not intended to limit the present invention.
