Vertical air-cooled double-cylinder permanent magnet speed regulator

Abstract

The invention provides a vertical air-cooled double-cylinder permanent magnet speed regulator, and belongs to the technical field of permanent magnet speed regulators. The vertical air-cooled double-cylinder permanent magnet speed regulator comprises a permanent magnet rotor assembly arranged on a load shaft, a conductor rotor assembly arranged on the input shaft of the motor, and a speed regulating mechanism, the permanent magnet rotor assembly and the conductor rotor assembly are concentrically arranged, the speed regulating mechanism is arranged on a shell, the speed regulating mechanism is far away from a permanent magnet disc, a rotating shaft is rotatably connected to an annular plate, two rocker arms are arranged on the rotating shaft, and the outer ends of the rocker arms are hinged to one end of a connecting rod; and the vertical air-cooled double-cylinder permanent magnet speed regulator further comprises a sliding sleeve, a first bearing is arranged on the sliding sleeve, the other end of the connecting rod is hinged to the outer sleeve of the first bearing, and the permanent magnet disc is arranged on the sliding sleeve. The vertical air-cooled double-cylinder permanent magnet speed regulator has the following advantage: the coupling area is conveniently changed to change the torque transmitted between the conductor rotor assembly and the permanent magnet rotor assembly, so the purpose of speed regulation is achieved.

[0002] The permanent drive load mechanism connects the drive device and the load equipment through a mechanical device, and adopts traditional mechanical cooperation for transmission, which will cause some irreversible problems, such as mechanical fatigue, friction loss, vibration and noise, etc., and precision must be ensured The installation accuracy can ensure the stability of the mechanical movement, but after a long time, the equipment will be damaged due to mechanical vibration or wear.

The speed change device of the vertical drive belt load mechanism is a device that changes the transmission ratio or speed of the output shaft and the input shaft. The traditional frequency conversion speed regulation is adopted, and the maintenance of the equipment is cumbersome and the maintenance cost is high, which affects the normal use and working cycle of the equipment.

In addition, the traditional structure of the permanent magnet governor has low utilization rate of the magnetic field, large radius of gyration, heavy equipment weight, large proportion of additional power consumed, large axial distance, complex heat dissipation system, high equipment cost and low transmission efficiency
