Problems solved by technology

[0004] However, the structure of the known permanent magnet governor still has shortcomings in practical application and needs to be improved
The disadvantage is that the device will generate eddy currents on the magnetic conductor disk when it is working, and the eddy current will generate an induced current that will cause the temperature of the magnetic conductor disk to be too high, and the permanent magnet will demagnetize under high temperature conditions, resulting in a decrease in the working efficiency of the device or failure to work normally.

Embodiment 1

[0028] A heat-dissipating magnetic conductor disk for a permanent magnet governor, comprising a conductor turntable 1, a fixed turntable 2, a heat dissipation turntable 3, a fixed plate 4, and a protective pillar 5;

[0029] Such as figure 1 , figure 2 As shown, the conductor turntable 1 and the fixed turntable 2 are coaxially fixed together, the conductor turntable 1 and the fixed turntable 2 have the same diameter, and a heat dissipation turntable 3 is fixedly installed on one side of the fixed turntable 2, the conductor turntable 1, the fixed turntable 2 and the The heat dissipation turntable 3 forms a three-layer structure coaxially fixed together, and the center of the three-layer structure formed by the conductor turntable 1 , the fixed turntable 2 and the heat dissipation turntable 3 is provided with a rotation hole 6 .

[0030] The fixed plate 4 includes a plate surface and a fixed block 401, the plate surface of the fixed plate 4 is an arc-shaped plate, and the arc ...

Embodiment 2

[0034] Such as Figure 6 As shown, in this embodiment, the heat dissipation turntable 3 is composed of multiple fan-shaped heat dissipation blocks. When installing, the heat dissipation fins are connected by circular arc iron sheets to form a complete circle, which can prevent the replacement of the entire heat dissipation turntable 3. Only replace damaged heatsinks when necessary.

[0035] When working, on the one hand, the circular heat sink 301 reduces the air resistance, and the setting of the bar-shaped protrusion 302 can provide enough wind force to quickly take the heat exported by the heat sink 301 away from the magnet disk; on the other hand, the protective pillar 5 The setting can stabilize the magnetic conductor plate and prevent large objects from accidentally falling into the magnetic conductor plate. At the same time, its crane beak structure can take away the heat in the device when the magnetic conductor plate rotates. Two heat dissipation methods make the devi...

Abstract

The present invention discloses a heat-dissipation magnetizer disk for a permanent magnet regulator. The magnetizer disk comprises conductor turntables, fixed turntables, heat-dissipation turntables,fixing plates and protection posts. The conductor turntables, the fixed turntables and the heat-dissipation turntables are coaxially and fixedly arranged, the fixed turntables are arranged between theconductor turntables and the heat-dissipation turntables, and the fixed turntables, the conductor turntables and the heat-dissipation turntables are coaxially arranged; each fixing plate comprises aplate surface and fixing blocks, wherein two ends of the plate surface are provided with the fixing blocks, each fixing plate is fixedly mounted on the two conductor turntables through the fixing blocks to form a cage structure, each protection pillar is arranged between each two fixing plates and is arranged around the peripheral edge of the conductor turntables; and cooling fins are arranged onthe heat-dissipation turntables. The heat-dissipation magnetizer disk is simultaneously subjected to cooling and heat dissipation by two means, and a cooling device and the heat-dissipation magnetizerdisk are integrally assembled so that a fan is not needed to install in the device and space waste is reduced.

Description

technical field [0001] The invention belongs to the field of shaft-connecting transmission equipment, and in particular relates to a heat-dissipating magnetizer disk for a permanent magnet governor. Background technique [0002] All countries in the world are actively solving the problem of energy demand. Among them, in addition to finding alternative energy sources, it is to improve the operational efficiency of various connecting institutions. At present, the place where power loss is most likely to occur is at the connection between components, such as: coupling. Its main function is to use components to connect the shafts of two different machines so that the two shafts can rotate together during the transmission process as a mechanical component that drives each other to rotate. However, during the process of transmission and rotation, the component will be affected by factors such as friction force and component characteristics, resulting in power loss. [0003] In o...
