背景技术 Background technique

Governor .
目前的永磁调速器都是通过改变导体转子与永磁转子之间的气隙从而控制导体转子切割磁力线的多少,来实现转矩调整的,由于这种方式存在很多弊端,本发明基于磁体同极相斥、异极相吸的原理,从改变外磁转子与内磁转子之间的作用力入手去设计新的永磁调速器,从而达到改变转矩的目的。 The current permanent magnet governor realizes the torque adjustment by changing the air gap between the conductor rotor and the permanent magnet rotor to control the number of magnetic lines of the conductor rotor cutting. Since there are many disadvantages in this way, the present invention is based on a magnet. The principle of the same pole reciprocal and the opposite pole attracting, from the change of the force between the outer magnetic rotor and the inner magnetic rotor, to design a new permanent magnet governor, thereby achieving the purpose of changing the torque.
为解决上述问题,本发明采取的技术方案为: 一种固定磁隙的永磁调速器,包括与主动轴连接的外磁转子以及经从动轴同心穿过的第一内磁转子和第二内磁转子,所述的外磁转子沿其内圆周面周向均匀分布有至少两个外永磁体,每个外永磁体磁极沿周向设置,且相邻两外永磁体的相邻侧磁极磁性相异;所述的第一内磁转子和第二内磁转子均沿各自的外圆周面周向均匀分布有至少两个第一内永磁体和第二内永磁体,各个内永磁体磁极沿周向设置,且同一内磁转子上相邻两内永磁体的相邻侧磁极磁性相异,第一内永磁体和第二内永磁体的磁极端面侧分别设有第一铁轭和第二铁轭,两内磁转子上的内永磁体数量相同;在第一内磁转子上设有驱动第一内磁转子相对第二内磁转子转动的磁路调节器,用于调节两内磁转子上内永磁体同名磁极的位置关系。所述的磁路调节器用于调节第一内永磁体和第二内永磁体同名磁极的位置关系,进而改变外磁转子与第一内磁转子、第二内磁转子之间的作用力。 具体调节过程: 通过磁路调节器 旋转 第一内磁转子 ,当 第二永磁体与第一永磁体的同名磁极处于相对应的位置时,第一铁轭、第二铁轭均被 磁化成相对应极性的强磁体 ,对外显示磁性最强,与外磁转子根据同极相斥异极相吸的原理产生最大的吸引力或排斥力, 从而使内、外磁转子同向或反向运动并实现力量传动; 相反,当 第二永磁体与第一永磁体的异名磁极处于相对应的位置时, 磁力线经 第一铁轭、第二铁轭 顺利穿越, 内部短路,第一铁轭、第二铁轭 对外不显示磁性; 外永磁体对第一、第二铁轭不产生作用力,内、外磁转子无法实现力量传递。 In order to solve the above problems, the technical solution adopted by the present invention is: A permanent magnetic governor with a fixed magnetic gap, comprising an outer magnetic rotor connected to a driving shaft and a first inner magnetic rotor and a second inner magnetic rotor concentrically passing through the driven shaft, the outer magnetic rotor along The inner circumferential surface is evenly distributed with at least two outer permanent magnets, each outer permanent magnet magnetic pole is circumferentially disposed, and adjacent side magnetic poles of adjacent two outer permanent magnets are magnetically different; the first inner magnetic rotor is And the second inner magnetic rotor are evenly distributed along the circumferential direction of the respective outer circumferential surfaces with at least two first inner permanent magnets and second inner permanent magnets, each inner permanent magnet magnetic pole is circumferentially disposed, and the same inner magnetic rotor upper phase The adjacent side magnetic poles of the adjacent inner permanent magnets are magnetically different, and the first inner yoke and the second inner yoke are respectively provided on the magnetic pole end sides of the first inner permanent magnet and the second inner permanent magnet, respectively The number of the permanent magnets is the same; the first inner magnetic rotor is provided with a magnetic circuit regulator for driving the rotation of the first inner magnetic rotor relative to the second inner magnetic rotor for adjusting the positional relationship of the inner permanent magnets of the same name on the inner inner magnetic rotors. The magnetic circuit regulator is used for adjusting the positional relationship between the first inner permanent magnet and the second inner permanent magnet of the same name, thereby changing the force between the outer magnetic rotor and the first inner magnetic rotor and the second inner magnetic rotor. The specific adjustment process is: rotating the first inner magnetic rotor by the magnetic circuit regulator, when the second permanent magnet and the first permanent magnet have the same name magnetic pole, the first iron yoke and the second iron yoke are magnetized into phases Strong magnet corresponding to polarity The external display shows the strongest magnetic force, and the outer magnetic rotor generates the maximum attractive force or repulsive force according to the principle of the same pole repulsive and opposite pole attraction, so that the inner and outer magnetic rotors move in the same direction or in the opposite direction and realize the power transmission; , when When the second permanent magnet and the different permanent magnet of the first permanent magnet are in corresponding positions, the magnetic lines of force pass through the first iron yoke and the second iron yoke smoothly, and the internal short circuit, the first iron yoke and the second iron yoke do not display magnetic properties externally. ; The outer permanent magnet does not exert a force on the first and second iron yokes, and the inner and outer magnetic rotors cannot transmit power.
第一内永磁体和第二内永磁体由异名磁极位置相对应转动到同名磁极位置相对应的过程就是两个内磁转子与外磁转子之间作用力由小变大的过程,从而实现传递力量的改变,由此实现调速功能。 一般情况下主动轴连接主电机,从动轴连接负载,但两者可以互换,即主动轴连接负载,从动轴连接主电机。 The process in which the first inner permanent magnet and the second inner permanent magnet are correspondingly rotated by the opposite-name magnetic pole position to the magnetic pole position of the same name is a process in which the force between the two inner magnetic rotors and the outer magnetic rotor is changed from small to large, thereby realizing The transmission of power changes, thereby achieving the speed control function. In general, the drive shaft is connected to the main motor, and the driven shaft is connected to the load, but the two can be interchanged, that is, the drive shaft is connected to the load, and the driven shaft is connected to the main motor.
此种方式相对于改变导体转子与永磁转子的轴向距离来说,降低了磁路调节器的功率消耗,降低热量产生,提高了扭矩的传递能力。 Compared with changing the axial distance between the conductor rotor and the permanent magnet rotor, this method reduces the power consumption of the magnetic circuit regulator, reduces heat generation, and improves the torque transmission capability.
外磁转子上的外永磁体数量与第一内磁转子上的第一内永磁体数量相同。当第一内磁转子、第二内磁转子与外磁转子永磁体数量相等时,可以实现输入、输出转速0~100%的调速功能。 The number of outer permanent magnets on the outer magnetic rotor is the same as the number of first inner permanent magnets on the first inner magnetic rotor. When the number of permanent magnets of the first inner magnetic rotor, the second inner magnetic rotor and the outer magnetic rotor is equal, the speed control function of the input and output speeds of 0 to 100% can be realized.
外磁转子上的外永磁体数量与第一内磁转子上的第一内永磁体数量不同,但第一内磁转子上的第一内永磁体与第二内磁转子上的第二内永磁体数量相同时,可以实现输入、输出转速0~N%的调速功能(可升速或降速,扭矩随N反比例改变、最大功率不变)。 The number of outer permanent magnets on the outer magnetic rotor is different from the number of first inner permanent magnets on the first inner magnetic rotor, but the first inner permanent magnet on the first inner magnetic rotor and the second inner permanent magnet on the second inner magnetic rotor When the number of magnets is the same, the speed control function of input and output speed 0~N% can be realized (the speed can be increased or decreased, the torque changes inversely with N, and the maximum power does not change).
所述的磁路调节器包括用于接收控制信号的调节执行器。 The magnetic circuit regulator includes an adjustment actuator for receiving a control signal.
所述的调节执行器可为电动执行机构、气动执行机构或液动执行机构。 使用过程中,将永磁调速器安装于某控制***中,压力、流量、液位或其他控制信号被控制***接收和处理,然后提供到调节执行器,由调节执行器的执行机构来控制第一内磁转子的转动,改变第一铁轭、第二铁轭对外显示磁性的大小。 The adjustment actuator can be an electric actuator, a pneumatic actuator or a hydraulic actuator. During use, the permanent magnet governor is installed in a control system, and pressure, flow, liquid level or other control signals are received and processed by the control system, and then supplied to the regulating actuator, which is controlled by the actuator of the regulating actuator. The rotation of the first inner magnetic rotor changes the magnitude of the magnetic properties of the first iron yoke and the second iron yoke.
本发明 由于采用了固定磁隙结构,大大提高了调速器的啮合面积并降低了装配难度, 降低热量产生,增大调速范围, 节约了稀土材料 , 大大提高了扭矩传递能力 。由于采用了磁力传递原理,所以实现了 输入、输出转速0~N%的调速功能,大大扩展了本发明的使用范围和领域; 由于采用了磁路调节结构,大大减小了执行调节机构的功率消耗并最大限度的缩小了调节执行机构的体积,从而大大缩小了调速器的整体体积,不但降低了材料消耗和节省了安装空间,更是给现场安装施工带来了方便。 The invention adopts a fixed magnetic gap structure, greatly improves the meshing area of the governor and reduces the assembly difficulty, reduces heat generation, and increases the speed regulation range. The rare earth material is saved, and the torque transmission capability is greatly improved. Since the principle of magnetic force transmission is adopted, the speed control function of input and output speeds of 0~N% is realized, which greatly expands the scope of use and field of the invention; Due to the magnetic circuit adjustment structure, the power consumption of the adjustment mechanism is greatly reduced and the volume of the adjustment actuator is minimized, thereby greatly reducing the overall volume of the governor, which not only reduces material consumption and saves installation. Space is also convenient for on-site installation and construction.
