Cylindrical rotating plate permanent magnet coupler

Abstract

The invention discloses a cylindrical rotating plate permanent magnet coupler which comprises a first shaft and a second shaft. The first shaft and the second shaft are separated and are coaxial. The first shaft is provided with a shaft sleeve I, a permanent magnet rotating plate, an inner layer carrying magnetic cylinder and an outer layer carrying magnetic cylinder. The inner layer carrying magnetic cylinder and the outer layer carrying magnetic cylinder are made of ferromagnetic materials. The inner wall of the inner layer carrying magnetic cylinder and the inner wall of the outer layer carrying magnetic cylinder are respectively provided with one circle of permanent magnets uniformly distributed. The pole direction of the permanent magnets is perpendicular to the axis of the rotating shaft. Every two adjacent magnets are installed in a hetero-polar mode. The second shaft is provided with a shaft sleeve II, a conductor rotating plate and a conductor cylinder connected with the conductor rotating shaft. The conductor cylinder is made of an excellent conductor. A gap between the conductor cylinder and the inner layer carrying magnetic cylinder and a gap between the conductor cylinder and the outer layer carrying magnetic cylinder keep equal. Transmission of different kinds of torque is achieved by adjusting the coupling area between rotors, the purposes of isolating vibration, reducing the speed and saving the energy are achieved, installing and debugging are easy, axial moving of a certain degree is allowed, torque transmission between the two parts can be achieved, and the purposes of isolating vibration, reducing the speed and saving the energy are achieved.

Description

technical field [0001] The invention relates to a driving device, in particular to a permanent magnet coupler of a cylindrical 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...
