Embodiment Construction

[0024] The following embodiments of the present invention are described in detail in conjunction with the accompanying drawings.

[0025] attached by figure 1 It can be seen that the laminated permanent magnet speed governor of the present invention includes a magnetic transmission member 4 with a concave-convex multi-ring shell structure respectively arranged on the driving rotor shaft (input shaft), and a concave-convex magnetic transmission member arranged on the driven shaft (output shaft) 1. The magnetic induction part 3, the bearing 5 and the bracket of the shape multi-ring shell structure. Depend on figure 1 It can be seen in the magnetic transmission part 4 and the magnetic induction part 3 of the concave-convex multi-ring shell structure respectively arranged on the driving rotor shaft and the driven rotor shaft. The multi-ring shell structure is divided into three layers. The convex ring shell parts of the magnetic transmission part 4 and the magnetic induction pa...

Abstract

The invention discloses a stacked type permanent magnet speed controller. A magnetism transmission piece and a magnetism sensing component which are of a concave-convex multi-ring shell structure are arranged on a magnetic transmission device of a driving rotor shaft and a driven rotor shaft which are arranged on the stacked type permanent magnet speed controller respectively, a convex ring portion of the magnetism transmission piece and a convex ring portion of the magnetism sensing component are inserted into a concave ring portion of the magnetism transmission piece and a concave ring portion of the magnetism sensing component respectively, and air gaps are arranged between the convex ring circumference surface of the magnetism transmission piece and the convex ring circumference surface of the magnetism sensing component to separate the convex ring circumference surface of the magnetism transmission piece and the convex ring circumference surface of the magnetism sensing component. Magnetizers made of soft iron and at least two permanent magnets are arranged on the convex ring shell circumference surface of the magnetism transmission piece, the permanent magnets are isolated through soft iron, and the magnetic line of force of the permanent magnets is perpendicular to a rotor axis. The convex ring shell circumference surface of the magnetism sensing component is composed of soft iron materials and copper bars, wherein the copper bars are arranged on the soft iron and are evenly and fixedly arranged on the circumference surfaces of the soft iron, and the section of each copper bar is rectangular. The stacked type permanent magnet speed controller can transmit large torque, and has the advantages of being high in response speed, small in motion vibration and capable of controlling speed in a stepless mode.

Description

technical field [0001] The invention relates to a speed governor adopting magnetizer and permanent magnet components for torque transmission, in particular to a permanent magnet speed governor with variable transmission torque. Background technique [0002] In large-scale mining, cement, pulp, petrochemical, metallurgy, electric power and other industries, due to the need for energy saving and easy operation, a large number of reducers, frequency converters, hydraulic couplers, etc. are used in the production process. Although it meets the parameter requirements required by the equipment, it is not necessarily energy-saving and environmentally friendly, and has high requirements on the environment. Therefore, its disadvantages are: complex system, poor maintainability, poor equipment adaptability to the environment, and easy to be disturbed by the surrounding environment; the existing The permanent magnet of the permanent magnet governor is flat or cylindrical. [0003] Ch...
