Gear Pair Adjustable Speed ​​Permanent Magnetic Coupling

Abstract

The invention discloses a permanent magnet coupler with a speed-adjustable gear pair. The permanent magnet coupler with the speed-adjustable gear pair comprises a power input shaft, a driving shaft, a left sleeve, a right sleeve, a left control panel, a right control panel, a magnet bearing disk, a moment transmission shaft, a driven shaft, a parallelogram four-bar mechanism and a power output shaft. The driving shaft is fixedly sleeved with the left sleeve. A radial protrusion at the right end of the left sleeve is provided with a left installing disk. A left copper ring is installed on the right end face of the left installing disk. A radial protrusion at the left end of the right sleeve is provided with a right installing disk. The moment transmission shaft is connected between the left installing disk and the right installing disk. The parallelogram four-bar mechanism is connected between the top of the left control panel and the top of the right control panel. A gear pair speed adjusting mechanism is connected between the bottom of the left control panel and the bottom of the right control panel. The gear pair speed adjusting mechanism comprises a first threaded sleeve, a second threaded sleeve and a bevel gear speed adjusting device. The permanent magnet coupler capable of adjusting speed well solves problems existing in the prior art and has the advantages of being simple and compact in structure, convenient to install and adjust, not prone to eccentricity, suitable for low-power occasions and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a permanent magnet coupling. Background technique [0002] The permanent magnet coupling is a torque transmission device, which was first used in naval ships and is a revolutionary new technology. [0003] The principle of the permanent magnet coupling is to realize the torque transmission from the motor to the load through the air gap between the copper / aluminum conductor and the permanent magnet. Its main structure is: a magnetic rotor assembly, composed of several rare earth permanent magnets, connected to the load side; copper / aluminum conductor rotor assembly, connected to the motor side. [0004] Permanent magnet couplings can be widely used in power generation, metallurgy, petrochemical, water treatment, mining and cement, pulp and paper, HVAC, shipping, irrigation and other industries for energy saving. In the above industries, the application types are ...

AI Technical Summary

Problems solved by technology

[0010] 3. There are permanent magnets installed on the two permanent disks, and the permanent magnets on the two disks have a magnetic force on each other, which will have an adverse effect on the next adjustment

[0011] 4. When adjusting, the permanent disk on one side is driven by the speed regulating mechanism, and the permanent disk drives the other permanent disk to move through the linkage device. This adjustment method is unreliable

[0012] 5. The speed regulating mechanism must be installed on the central shaft, and must be on the left or right side of the coupling, which increases the axial length and increases the possibility of eccentricity of the coupling

[0013] 6. The speed regulating mechanism adopts a cam mechanism, and the movement track is a space curve, and the external drive device is not easy to compensate for the axial offset

[0014] 7. At present, this type of coupling is only suitable for large and medium power occasions, not for low power occasions
