Abstract

The utility model relates to a magnetic force coupler, which comprises a machine seat, a case cover, a conductor rotor and a magnetic rotor. The machine seat is fixed on the ground, and the machine seat and the case cover are connected to form a horizontal middle opening structure. A driven machine seat, an input shaft and an output shaft are arranged in the coupling, wherein the output shaft and the input shaft extend from the case cover, and the inner end of the input end is provided with a needle roller bearing connected with the inner end of the output end. The input shaft is connected with a conductor plate connected with the conductor rotor, the output shaft is connected with a permanent magnetic groove plate connected with the magnetic rotor, and the permanent magnetic plate is connected to a worm gear transmission mechanism through an angular contact bearing. The magnetic force coupling can greatly improve use performance and prolong service life and is convenient and simple to overhaul.

Description

Magnetic coupling

Technical field

The utility model relates to a kind of transmission device, relates to a kind of magnetic coupling specifically.

Background technique

The working principle of magnetic coupling is followed the Coulomb's law of magnetic; I.e. two magnets separated by a distance; Because the magnetic field induction effect, they are without any need for traditional mechanical means, through the bonding force of magnet; Just can be delivered to the another one magnet to power from a magnet, constitute a non-contact transmitting torque mechanism.

Magnetic coupling is divided into conductor rotor that links to each other with prime mover and the magnet rotor two-part that link to each other with load, adjusts the output torque through the gap (air gap) between adjustment conductor rotor and the magnet rotor, thereby realizes speed governing.

There is following defective in above-mentioned magnetic coupling: 1) after magnetic coupling works long hours, rotor is because a variety of causes regular meeting is damaged, and rotor is damaged easily; Existing magnetic coupling is more during exchanging rotor; Need support, chassis lid be moved, newer rotor put into behind the taking-up rotor, because support is mobile; Centering be need proofread and correct again, maintenance, dead time prolonged greatly; 2) existing output shaft structure is an overhanging beam, and its outer end is connected on the stator through bearing, and is inner unsettled; This kind structure causes projecting shaft rigidity relatively poor; In use bend easily even rupture, influence the usability of Coupler, cause potential safety hazard; 3) in the working procedure, the axial force that produces between conductor rotor and the magnet rotor is bigger, if can not eliminate timely and effectively, will bring extremely heavy burden to output shaft, input shaft, and shortened dramatically its working life.

The model utility content

The utility model is to above-mentioned defective, and purpose is to provide a kind of can make the usability of Coupler, working life greatly improve, and overhauls convenient and simple magnetic coupling.

The technological scheme of the utility model is: the utility model includes support, chassis lid, conductor rotor, magnet rotor, and support fixes on the ground, and support and chassis lid are connected to horizontal middle open type structure; Establish the input shaft, the output shaft that stretch out from support, chassis lid in the Coupler, the end that input shaft is in the Coupler is provided with and the inner needle bearing that is connected of output shaft; Be connected with the conductor plate that is connected with conductor rotor on the input shaft, be connected with the permanent magnetism frid that is connected with magnet rotor on the output shaft, the permanent magnetism frid is connected to Worm and worm-wheel gearing through angular contact bearing.

Offer bosh between conductor rotor of the utility model and the conductor plate.

The utility model has the advantages that: 1) the utility model stationary part is made up of support and chassis lid, and after chassis lid was taken apart, rotor portion can integral body hang out; The rotor that fast changeable is subsequent use; Because support is not moving, need not to proofread and correct centering, will shorten maintenance downtime greatly; 2) the utility model is established needle bearing in the inner of input shaft, and makes it a moving fulcrum as output shaft, and another fulcrum of output shaft is a fixed end, is contained in the Worm gear case bearing support, and the rigidity of output shaft, intensity are improved greatly; 3) axial force that produces between the utility model rotor and the magnet rotor is sent to big ground through angular contact bearing, worm and gear, has reduced the work load of input shaft, output shaft, has improved its working life.
