Embodiment 1

[0051] see figure 1 as well as figure 2 , this embodiment provides a hybrid permanent magnet coupling for coupling the driving shaft 11 and the driven shaft 12 . Among them, the hybrid permanent magnet coupling includes a driving disc 1 and a driven disc 2 .

[0052] The driving disc 1 is connected with the driving shaft 11 and includes two coaxially arranged driving rings 3 . Each driving ring 3 includes a plurality of magnets 4 , and the plurality of magnets 4 are arranged around the axial direction of the driving shaft 11 at equal intervals. The quantity of the magnet one 4 is an even number, and the magnet one 4 is provided with its two magnetic poles along the thickness direction, that is, the magnet one 4 is provided with two magnetic poles in the direction parallel to the axial direction of the drive shaft 11, and is arranged on the magnet one 4 on both sides.

Embodiment 2

[0072] see Figure 3-7 , this implementation provides a hybrid permanent magnet coupling, which is similar to that of Embodiment 1, the difference is that the eddy current disk 9 is bonded or clipped to the corresponding back iron 13 .

[0073] In this embodiment, the two torque discs 6 can be fixed by other structures not shown in the figure, such as the hole structure of the rotary part of the hybrid permanent magnet coupling applied in this embodiment, etc., and a plurality of magnets-4 Between the two magnets 7 and the three magnets 10 can be connected by gluing to form a whole. And the driving disc 1 and the driving shaft 11, the driven disc 2 and the driven shaft 12 can all be installed by means of welding, clamping or the like. In this way, the manufacturing materials of the hybrid permanent magnet coupling can be reduced, and at the same time the overall weight of the hybrid permanent magnet coupling can be reduced, and the working efficiency of the hybrid permanent m...

Abstract

The present invention discloses a hybrid permanent magnet coupling for coupling a drive shaft and a driven shaft, and includes a drive plate and a driven plate. The drive plate is coupled to the driveshaft and includes two active rings that are coaxially disposed. Each of the active rings includes a plurality of magnets 1 disposed axially and equally spaced around the drive shaft. The driven plate is connected to the driven shaft, and includes a synchronous plate and two torque plates respectively disposed on both sides of the synchronous plate and disposed coaxially with the synchronous plate. The synchronous plate comprises a plurality of magnets 2 arranged in an axial direction of the driven shaft and equally spaced. In each two adjacent magnets 2, one of the magnetic field directionsis opposite to the magnetic field direction of the other one, and the magnets 2 and the magnets 1 form torque. The two torque plates are arranged at the two sides of the drive plate, the torque plateshave the same distance with the drive plate, and the torque plates generate high instant torque in the high-rotation speed working condition. The rigid connection of the drive shaft and the driven shaft is achieved, the hybrid permanent magnet coupling has a torque adaptive regulation function to generate extremely high instantaneous torque and improve the stability.

Description

technical field [0001] The invention relates to a permanent magnet coupling in the field of shaft couplings, in particular to a hybrid permanent magnet coupling. Background technique [0002] Coupling refers to a device that connects two shafts or shafts and rotating parts, and rotates together during the transmission of motion and power, and does not disengage under normal conditions. Couplings are sometimes used as a safety device to prevent excessive loads on the connected parts and play a role in overload protection. When the existing coupling realizes the linkage between the driving shaft and the driven shaft, due to the fixed torque, when the speed of the driving shaft and the driven shaft changes, the coupling is easily damaged, resulting in low service life and poor stability of the coupling . Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a hybrid permanent magnet coupling to solve the problems of low s...
