Disc-shaped rotary-plate permanent magnetic coupler

Abstract

The invention discloses a disc-shaped rotary-plate permanent magnetic coupler. The disc-shaped rotary-plate permanent magnetic coupler comprises a first shaft and a second shaft which are separated and coaxial, wherein the first shaft is provided with a hub I, a disc-shaped permanent magnetic rotary plate I and a disc-shaped permanent magnetic rotary plate II, the disc-shaped permanent magnetic rotary plate I and the disc-shaped permanent magnetic rotary plate II are arranged in parallel, the disc-shaped permanent magnetic rotary plate I is arranged on the first shaft through the hub I, the two disc-shaped permanent magnetic rotary plates are connected through a connection rod, one or more circles of permanent magnets are arranged in the disc-shaped permanent magnetic rotary plates I and II, poles of adjacent permanent magnets are arranged in a heterospolar or homopolar mode, the two rotary plates are arranged oppositely according to poles of the permanent magnets, and the directions of the poles are axially distributed along the permanent magnetic rotary plate; the second shaft is provided with a hub II and a conductor rotary plate, the second shaft is sleeved with the hub II in a connected mode, and the conductor rotary plate is connected with the hub II through bolts and arranged between the two permanent magnetic rotary plates. Different types of torque can be transmitted by adjusting the coupling area of rotors, and the purposes of vibration isolation, speed reduction and energy saving are achieved; meanwhile, installation and debugging are relatively easy, a certain amount of axial movement is allowed, torque transmission between the two permanent magnetic rotary plates and the conductor rotary plate is achieved, and the purposes of vibration isolation, speed reduction and energy saving are achieved.

Description

technical field [0001] The invention relates to a driving device, in particular to a permanent magnet coupler of a disc-shaped turntable adopting the principle of permanent magnet eddy current induction. Background technique [0002] The existing motor systems basically have the phenomenon of large horses and small carts, and the waste of electric energy is serious, and the traditional mechanical coupling inevitably transmits vibration from one end to the other through the coupling, which obviously does not have the ability to isolate vibration and Energy-saving performance, the "12th Five-Year Plan for Energy Conservation and Emission Reduction" clearly proposes to use energy-saving technologies such as permanent magnet eddy current flexible transmission to optimize system operation and control, and improve the overall operating efficiency of the system. [0003] In this case, the permanent magnet coupler is a new ideal choice in the field of motor energy saving. Contents...
