Problems solved by technology

This structure has the following problems: 1. Large transmission ratio transmission, high noise and large power loss; The contact surface is small, resulting in uneven force on the track, and high requirements for the strength of the friction wheel
Fourth, the height changes caused by the unexpected failure of the magnet
In short, any moving magnetic levitation system must be equipped with a height adjustment device, otherwise it cannot work normally and stably

Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] Fig. 2 is the A-A sectional view of the front view of the magnetic levitation arc motor automatic two-wing revolving door, and Fig. 3 is the B-B sectional view of the front view of the magnetic levitation arc motor automatic two-wing revolving door.

[0020] As shown in the figure, the outer ring track 5 is installed on the upright column 7 which is relatively fixed to the ground, the permanent magnets 1 and 3 are installed on the inner circle of the outer ring track 5, and the permanent magnet 2 and the electromagnet 4 are installed on the freely rotatable inner ring On the outer circle of 6, it is located in the middle of the above permanent magnets 1 and 3, and the positions are corresponding. The outer circle of the above-mentioned inner ring 6 is the place where the load is the largest, and is also close to the maximum diameter of the revolving door, where ...

Abstract

The invention relates to an automatic two-wing revolution door driven by magnetic levitation and arc motor, comprising magnetic bearing and arc motor driving equipment. Permanent-magnet is assembled on outer ring of revolution door and permanent-magnet and electromagnet are assembled on inner ring. By the principle of homopolarity repulsion and heterpolar absorption of magnetic material, revolution partition is suspended by the weight of moving part in magnetic balance two-wing revolution door and the suspension height is adjusted by controlling flux of electromagnet. Electromagnetic torque generated by interaction between primary winding set on the inner ring of arc motor and secondary winding set on the outer ring of arc motor make inner ring and door. Because of global suspension of moving part in revolution door, non-contacting with fixed part, no friction and small driving force the equipment is provided with non-friction, low noise, low energy consuming and simple structure and applied in hotel, cabaret and office building so on widely.

Description

technical field [0001] The invention relates to an automatic revolving door used in buildings, in particular to an automatic two-wing revolving door which utilizes magnetic force to suspend the door and is driven by an arc motor. Background technique [0002] The large two-wing automatic revolving door used in the building adopts the door wing suspension method because the rotating part is heavy. Load-bearing and transmission between the ring tracks (friction wheels roll along the outer track). Two of the friction wheels are driving wheels, which are connected with the motor reducer to provide rotational power and also bear weight. The rest are driven wheels, which only play a load-bearing role. This structure has the following problems: 1. Large transmission ratio transmission, high noise and large power loss; 2. Due to the use of friction wheels, various wear and tear are large, and the life of friction wheels and other transmission parts is short; 3. Due to friction whe...
