Multi-group multi-disc multi-air-gap linkage adjusting type magnetic coupler

Abstract

The invention discloses a multi-group multi-disc type multi-air-gap linkage adjusting type magnetic coupler which comprises a plurality of movably connected composite discs, and each composite disc comprises a conductor rotor group and a permanent magnet rotor group. The permanent magnet rotor group comprises two permanent magnet yoke iron discs which are connected with each other and can move relatively and axially, and permanent magnets which are respectively arranged on the two permanent magnet yoke iron discs; the conductor rotor group comprises two fixedly connected conductor yoke discs and conductors respectively arranged on the two conductor yoke discs; according to the invention, the conductor rotor group is used as a driving end, and the permanent magnet rotor group is used as a driven end; each composite disc forms two air gap lengths, and each composite disc and the other composite disc form a plurality of groups of air gap lengths; in addition, a single group of driven end rotors are driven by a speed regulation device to realize axial relative displacement, so that the lengths of a plurality of air gaps in the multiple groups of multi-disc magnetic couplers realize linkage regulation to achieve the purpose of speed regulation or torque change of the magnetic couplers, and the structure can obtain relatively large electromagnetic torque and power; and the device can be applied to occasions with large axial dimensions and limited radial dimensions, such as ocean platforms and large ships and warships.

Description

technical field [0001] The invention belongs to the technical field of transmission in mechanical engineering, in particular to a multi-group multi-disk multi-air-gap linkage adjustment type magnetic coupler. Background technique [0002] In my country, the proportion of energy consumed by pumps and fans in the motor is relatively high. It is an energy-saving way to adjust the speed of the motor working machine by means of speed regulation. Adverse effects, and maintenance is more difficult. The new magnetic transmission device magnetic coupling has the advantages of maintenance-free, high efficiency and energy saving, stability and reliability, overload protection, etc., and is widely used in pumps and fans. However, in submarines, underwater tunnels and other occasions where the axial size is large but the radial size is limited, the use of the magnetic coupler will be limited, and the load capacity of the magnetic coupler is not strong compared with the traditional couple...

Problems solved by technology

However, there are only two sets of permanent magnet rotors in this invention, and only two sets of air gaps can be formed with the conductor rotor, and cannot continue to increase on this basis. Under the requirement of higher power, the magnetic coupler can only To increase the structural size, it is difficult to use in occasions with limited radial size
