Description
技术领域 technical field
本发明涉及一种隐极型外转子磁阻式磁力耦合器。 The invention relates to a hidden pole type outer rotor reluctance type magnetic coupler.
背景技术 Background technique
现有的磁力耦合器按工作原理可分为永磁式,鼠笼式和磁阻式。永磁式磁力耦合器的特点是:内外两个转子均含有永磁体,力密度大,传动效率高,但由于永磁体居里温度的限制,此类磁力耦合器不能应用于高温场合,且永磁体粘接工艺使用的有机粘接剂对工作所处的流体介质有污染;鼠笼式磁力耦合器中的一个转子为导体构成的鼠笼,不含永磁体,可用于高温场合,但其工作原理类似于感应电机,在传动时鼠笼中会感应出电流而导致额外的损耗,使传动效率降低,且感应电流会引起工作介质的电化学反应;磁阻式磁力耦合器中的一个转子仅由导磁材料构成,不含永磁体,既可以用于高温场合,又可获得比鼠笼型磁力耦合器更高的效率,现有磁阻式磁力耦合器为凸极结构,在流体介质中旋转时阻力较大,会导致整体传动效率低。 The existing magnetic coupler can be divided into permanent magnet type, squirrel cage type and reluctance type according to the working principle. The characteristics of the permanent magnet magnetic coupling are: both the inner and outer rotors contain permanent magnets, the force density is high, and the transmission efficiency is high. The organic adhesive used in the magnet bonding process pollutes the fluid medium in which it works; one rotor in the squirrel-cage magnetic coupler is a squirrel cage made of conductors, which does not contain permanent magnets and can be used in high-temperature applications, but its work The principle is similar to that of an induction motor. During transmission, a current will be induced in the squirrel cage, resulting in additional loss, which will reduce the transmission efficiency, and the induced current will cause electrochemical reactions in the working medium; one rotor in the reluctance magnetic coupling is only Composed of magnetically permeable materials without permanent magnets, it can be used in high-temperature applications and achieve higher efficiency than squirrel-cage magnetic couplers. The existing reluctance-type magnetic couplers have a salient pole structure. Larger resistance when rotating will result in low overall transmission efficiency.

实施例1Example 1
一种隐极型外转子磁阻式磁力耦合器,其组成包括:外转子5、屏蔽套1、内转子2,所述的内转子2为圆柱形,所述的圆柱形内转子2的内圆周面固定设置在传动轴3上,所述的圆柱形内转子2的外圆周面固定连接内转子磁钢4,所述的内转子磁钢4为瓦片形,并沿内转子2排列一周,所述的内转子磁钢4的外圆周面与屏蔽套1之间设有内层间隙7,所述的屏蔽套1的外圆周面与外转子5的内圆周面之间设有外层间隙8,所述的外转子5为圆筒形,所述的圆筒形外转子5上沿轴向开有多组开槽6,所述的内转子磁钢4包括至少一对瓦片形永磁体,所有的瓦片形永磁体依次紧密相贴设置,所有的瓦片形永磁体均为径向充磁或平行充磁,且每相邻的两个瓦片形永磁体充磁方向相反。 A hidden pole type outer rotor reluctance magnetic coupler, which consists of an outer rotor 5, a shielding sleeve 1, and an inner rotor 2, the inner rotor 2 is cylindrical, and the inner rotor 2 of the cylindrical inner rotor The peripheral surface is fixedly arranged on the transmission shaft 3, and the outer peripheral surface of the cylindrical inner rotor 2 is fixedly connected with the inner rotor magnetic steel 4, and the inner rotor magnetic steel 4 is tile-shaped, and is arranged along the inner rotor 2 for a circle , an inner layer gap 7 is provided between the outer peripheral surface of the inner rotor magnetic steel 4 and the shielding sleeve 1, and an outer layer is provided between the outer peripheral surface of the shielding sleeve 1 and the inner peripheral surface of the outer rotor 5 The gap 8, the outer rotor 5 is cylindrical, the cylindrical outer rotor 5 is provided with multiple sets of slots 6 in the axial direction, and the inner rotor magnetic steel 4 includes at least a pair of tile-shaped Permanent magnets, all tile-shaped permanent magnets are arranged closely in sequence, all tile-shaped permanent magnets are magnetized radially or parallelly, and the magnetization direction of each adjacent two tile-shaped permanent magnets is opposite .
实施例2Example 2
实施例1所述的一种隐极型外转子磁阻式磁力耦合器,所述的多组开槽6相对于传动轴3中心对称设置,每组开槽6包括多对弧形槽,所述的多对弧形槽相对于传动轴3中心对称设置,每组开槽6的多对弧形槽的凸圆弧面均朝向外转子5外圆周面设置。开槽使得隐极外转子在磁路上具有不对称性,可在隐极结构中产生类似凸极结构转子的凸极效应,从而产生磁阻转矩,实现磁力耦合。 In the secluded pole type outer rotor reluctance magnetic coupler described in Embodiment 1, the multiple sets of slots 6 are arranged symmetrically with respect to the center of the transmission shaft 3, and each set of slots 6 includes multiple pairs of arc-shaped slots, so The multiple pairs of arc-shaped grooves described above are arranged symmetrically with respect to the center of the transmission shaft 3 , and the convex arc surfaces of the multiple pairs of arc-shaped grooves in each group of slots 6 are all set toward the outer circumferential surface of the outer rotor 5 .

By setting the arc-shaped slots, when the relative position of the inner and outer rotors changes, the difference in reluctance change of the closed magnetic circuit of the permanent magnet magnetic field line is the largest, thereby generating the largest reluctance torque.
实施例4Example 4
实施例1所述的一种隐极型外转子磁阻式磁力耦合器,所述的内转子磁钢4的外圆周面与屏蔽套1之间的内层间隙7为0.7~3mm,所述的屏蔽套1的外圆周面与外转子5的内圆周面之间的外层间隙8为0.7~3mm。间隙的设置首先可以保证在一定的装配精度下内外转子的通过屏蔽套的隔离传动;更重要的是可以保证磁阻转子工作于高温流体介质时,永磁转子可设置扇叶和开槽对间隙进行强制空气冷却,避免永磁体因温度过高而产生退磁。 In the hidden pole type outer rotor reluctance magnetic coupler described in Example 1, the inner layer gap 7 between the outer circumferential surface of the inner rotor magnetic steel 4 and the shielding sleeve 1 is 0.7~3mm, and the The outer gap 8 between the outer peripheral surface of the shielding sleeve 1 and the inner peripheral surface of the outer rotor 5 is 0.7-3mm. The setting of the gap can firstly ensure the isolation transmission of the inner and outer rotors through the shielding sleeve under a certain assembly accuracy; more importantly, it can ensure that when the reluctance rotor is working in a high-temperature fluid medium, the permanent magnet rotor can be provided with fan blades and slots for the gap Perform forced air cooling to avoid demagnetization of permanent magnets due to excessive temperature.
实施例5Example 5
实施例1所述的一种隐极型内转子磁阻式磁力耦合器,所述的内转子2和外转子5由冲压好的硅钢片叠压成型构成。 In the embodiment 1 of a secluded pole type inner rotor reluctance magnetic coupler, the inner rotor 2 and the outer rotor 5 are formed by lamination of stamped silicon steel sheets.
工作原理为:外转子静止时,内转子磁钢上的永磁体建立磁场,磁力线通过外转子磁钢上的永磁体、内转子、外转子中所开槽的槽间导磁材料部分构成闭合回路,此闭合路径为磁路中磁阻最小的部分;当外转子旋转时,内转子与外转子之间相对位置发生改变,磁路的磁阻会变大;由于磁力线总是沿磁阻最小的路径闭合,所以会在内转子与外转子之间产生磁阻转矩,以阻碍内转子与外转子之间的相对运动;磁阻转矩最终会使得内外转子保持同步运动,从而完成非接触式磁力传动。 The working principle is : when the outer rotor is stationary, the permanent magnet on the magnetic steel of the inner rotor establishes a magnetic field, and the magnetic field lines pass through the permanent magnet on the magnetic steel of the outer rotor, the inner rotor, and the magnetic material between the slots in the outer rotor to form a closed loop. , this closed path is the part with the least reluctance in the magnetic circuit; when the outer rotor rotates, the relative position between the inner rotor and the outer rotor changes, and the reluctance of the magnetic circuit will increase; The path is closed, so the reluctance torque will be generated between the inner rotor and the outer rotor to hinder the relative movement between the inner rotor and the outer rotor; the reluctance torque will eventually make the inner and outer rotors move synchronously, thus completing the non-contact Magnetic drive.
在外转子上沿轴向进行开槽;开槽分段进行,每段开槽之间留有一定的间隙保证外转子材料的连接宽度,连接宽度的选择应根据材料强度进行校核计算,以满足磁力耦合器工作时传递力矩与旋转时离心力所产生的合应力不会产生明显形变和断裂。 Slotting is carried out on the outer rotor along the axial direction; slotting is carried out in sections, and a certain gap is left between each section of slotting to ensure the connection width of the outer rotor material. The selection of the connection width should be checked and calculated according to the material strength to meet When the magnetic coupler is working, the resultant stress generated by the torque transmission and the centrifugal force during rotation will not produce obvious deformation and fracture.
