Suspension cone type permanent magnet speed regulating device

Abstract

The invention discloses a hanging-cone disc-type permanent-magnet speed regulator. The hanging-cone disc-type permanent-magnet speed regulator comprises a disc-type permanent-magnet speed regulator and a support seat, wherein a hanging cone device is arranged on the disc-type permanent-magnet speed regulator, an alarm device is arranged on the support seat, a spring on the hanging cone device canbe compressed or stretched when an input shaft or an output shaft moves, a conical head can be driven to move in a sliding groove, a contact type sensor is arranged on the support seat according to anaxial endplay setting value, the conical head slides in the sliding groove and contacts an induction head when the input shaft or the output shaft reaches the axial endplay setting value, the contacttype sensor can give out a warning signal to a corresponding alarm, the alarm which receives the signal gives out a warning, a motor and a conductor rotor or a speed regulation device and a permanent-magnet rotor are detected by a worker according to the position of the alarm, the problem range is shortened, the reason of excessively large axial endplay also can be timely and rapidly found out and solved, normal production operation is not affected, monitoring of the axial endplay is achieved, and the hanging-cone disc-type permanent-magnet speed regulator is a novel permanent-magnet speed regulator.

Description

technical field [0001] The invention relates to a speed regulating device, in particular to a cone-disk type permanent magnet speed regulating device. Background technique [0002] Permanent magnet speed regulation (permanent magnet transmission) is a revolution in the history of transmission. Its simple structure, reliable operation, energy saving and consumption reduction are very well used in modern industries. It is mainly used in petroleum, petrochemical, electric power, mining, Energy-saving motor drive systems in steel, chemical, cement and other industries. [0003] The basic principles of the disc permanent magnet governor and the barrel permanent magnet governor are the same, they both generate relative motion through the conductor rotor and the permanent magnet rotor, thereby generating an alternating induction magnetic field on the conductor rotor, and the alternating induction magnetic field Mesh with the alternating permanent magnetic field to generate torque ...

AI Technical Summary

Problems solved by technology

[0004] Under the same power condition, the cylindrical product is lighter in weight, smaller in size, smaller in moment of inertia and higher in efficiency than the disc type product; the magnetic force direction of the cylindrical product is radial, so larger axial movement is allowed, while the disc structure The direction of the magnetic force is axial, so the requirements for the axial movement are very strict. At present, there is no disc permanent magnet governor to monitor the axial movement. When the staff checks the causes of the axial movement, they need to check one by one, which is inefficient. and affect normal production
