Technical Field

[0002] In industrial applications, the energy consumption of motor drag accounts for a large proportion, among which the energy consumption of fan and pump loads cannot be ignored. In the speed regulation of fan and pump loads, the magnetic coupling is an important speed regulation device. It forms electromagnetic field coupling through the contactless connection between the active disk and the driven disk to achieve the transmission of torque and speed. Due to the simple structure of the magnetic coupling, it has high operating reliability and relatively low maintenance cost. The contactless transmission method makes it have low requirements on the working environment and neutrality. After years of development, the magnetic coupling has received widespread attention from all walks of life.

[0036] How it works

[0037] In actual use, when the driving roller 1 rotates, the groove on the inner wall of the assembly seat 201 drives the assembly seat 201 to rotate together. The limiting seat 208 in the assembly seat 201 is inserted into the limiting window 213 on the surface of the connecting roller 212 under the action of the torsion spring 207, so that the connecting roller 212 is fixedly connected to the assembly seat 201, thereby transmitting power to the connecting roller 212, and the connecting roller 212 drives the active magnetic disk 214 to rotate. The active magnetic disk 214 drives the driven magnetic disk 215 to rotate through the magnetic field coupling effect, and then drives the driven roller 216 to rotate. By moving the assembly seat 201, the distance between the two assembly seats 201 is changed, thereby changing the By changing the position of the connecting roller 212 in the assembly chamber 203, the change in the distance between the active magnetic disk 214 and the driven magnetic disk 215 will affect the magnetic field coupling strength, thereby changing the connection torque of the coupler to achieve speed regulation. The assembly seat 201 is fixed to the driving roller 1 through a groove, and the connecting roller 212 is connected to the assembly seat 201 through a limit seat 208 and a limit window 213. The structure is simple and the connection is stable and reliable. The straight-line distance between the active magnetic disk 214 and the driven magnetic disk 215 can be changed by moving the assembly seat 201, thereby adjusting the magnetic field coupling strength and achieving the adjustment of the coupler connection torque to meet the power transmission requirements under different working conditions.

[0038] The assembly cylinder 301 is sleeved on the surface of the active disk 214 and the driven disk 215, and is fixed to the connecting roller 212 and the driven roller 216 through the oil seal ring 217 to prevent silicone oil leakage. The silicone oil filled in the inner cavity of the assembly cylinder 301 facilitates the operation of the coupler and plays a certain heat dissipation role. The coolant flows into the fixing ring 302 from the liquid inlet pipe 304, and then flows around the active disk 214 and the driven disk 215 through the spiral cylinder 303. After the disk is cooled, it flows out from the drain pipe 305 and enters the condenser 306 for cooling. The cooled coolant flows through the liquid inlet pipe 304 again. The heat dissipation component 3 adopts a design in which a spiral cylinder 303 surrounds the active magnetic disk 214 and the driven magnetic disk 215, thereby increasing the contact area between the coolant and the magnetic disk and improving the heat dissipation efficiency. The oil seal ring 217 of the heat dissipation component 3 ensures that the silicone oil and the coolant will not leak, thereby improving the reliability of the device. The coolant forms a cycle through the liquid inlet pipe 304, the fixed ring 302, the spiral cylinder 303, the drain pipe 305 and the condenser 306, continuously dissipating heat for the coupler, thereby ensuring the stability of the device during long-term operation.
