High-speed disc type permanent magnet speed regulating device

Abstract

The invention discloses a high-speed disc type permanent magnet speed regulating device, which comprises a casing, wherein one end of the casing is connected with an input shaft through a bearing; anoutput shaft is arranged at one end, far away from the input shaft, of the casing; a conductor disc is arranged on the input shaft; a magnet disc is arranged on the output shaft; a conductor ring is arranged at one end, near the magnet disc, of the conductor disc; a permanent magnet block is embedded in one side, near the conductor disc, of the magnet disc; a lower position limiting warning devicearranged on the casing is arranged at the lower side of the conductor disc and the magnet disc; a window is arranged at one side, far away from the lower position limiting warning device, of the casing; and a temperature sensor is arranged on the inner wall of one side, near the window, of the casing. When the input shaft and the output shaft exceed the allowed jumping range, warning can be givenout; workers can conveniently perform overhaul according to the warning position; meanwhile, warning can be given out when the temperature in the casing is too high; cold air can be timely blown andsupplied by the workers; the service life of parts can be prolonged; and the normal work of the permanent magnet speed regulating device is ensured.

Description

technical field [0001] The invention relates to the field of permanent magnet speed regulating devices, in particular to a high-speed 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, The joint regulator of the motor drive system in the steel, chemical, cement and other industries can adjust the relative position of the cylindrical permanent magnet rotor and the cylindrical conductor rotor in the axial direction to change the effective part of the coupling between the permanent magnet rotor and the conductor rotor. The torque transmitted between the two can realize repeatable, adjustable and controllable output torque and speed, and realize ...

Problems solved by technology

[0003] The motor, load and the main body of the permanent magnet eddy current flexible transmission governor are all metal components. The permanent magnet material on the permanent magnet rotor of the permanent magnet eddy current flexible transmission governor and the eddy current magnetic force generated during work have axial attraction, resulting in The rotor of the motor and the load moves axially, and the magnetic force direction of the disk structure is axial, so the requirements for axial movement are very strict. Excessive movement will increase the wear and temperature of the equipment and shorten the service life of the equipment , so we designed a high-speed disc permanent magnet speed control device to solve the above problems
