Description

An Inner Rotor Cooling Type High Power Eddy Current Governor

technical field

The invention relates to a speed governor, in particular to an inner rotor cooling type high-power eddy current speed governor.

Background technique

The existing permanent magnet eddy current speed regulating device is mainly composed of two parts: a permanent magnet rotor and a copper (or other conductor) rotor. Generally, the shaft of the motor and the shaft of the working machine are respectively connected to one of the rotors. There is an air gap (called an air gap) between the copper rotor and the permanent magnet rotor, and there is no mechanical connection for torque transmission. In this way, a soft (magnetic) connection is formed between the motor and the working machine, and the shaft torque and speed of the working machine can be changed by adjusting the air gap, so it can adapt to various harsh environments, and because there is no direct mechanical connection, the mechanical loss.

In the structure of the existing disc vortex governor, the following two methods are usually adopted:

(1) The inner rotor permanent disk, the outer rotor conductor disk; the position of the outer rotor disk is fixed, and the structure of the inner rotor disk is adjusted;

(2) The permanent disk of the outer rotor, the conductor disk of the inner rotor, the position of the outer rotor disk is fixed, and the structure of the inner rotor disk is adjusted.

Since most of the heat generated by the eddy current governor is on the conductor disk, the heat dissipation device of the eddy current governor is placed on the conductor disk side instead of the permanent magnet side. For low-power eddy current governors, it is generally possible to use natural heat dissipation by air flow and heat dissipation by heat sinks. However, for high-power disc vortex governors, the cooling effect of air cooling is insufficient, and coolant cooling is usually required.

In the structure of the existing high-power disk eddy current governor, the inner rotor permanent disk and the outer rotor conductor disk are used without exception; the position of the outer rotor disk is fixed, and the structure of the inner rotor disk is adjusted; the cooling system is set on the outer rotor disk The way. This inner rotor adjustment mechanism has the following technical problems to be overcome:

1. Although cooling on the outer rotor disk can play a role in heat dissipation, since the heat dissipation mechanism is located on the periphery of the entire speed control mechanism, the speed control mechanism needs to be sealed as a whole, and the sealing requirements are high. The site often brings cooling medium due to sealing problems. Penetration into the lubrication system can cause equipment failure.

2. Although the heat generation of the permanent disk itself is small, the heat conduction and radiation of the conductor disk to the permanent disk through the air also needs to be dissipated;

3. When the permanent magnet eddy current speed regulating device is processed, especially when it is assembled and repaired, it needs to adjust the inner and outer rotors as a whole, so that an accurate symmetrical air gap can be obtained finally. However, after the outer rotor is assembled, it becomes very difficult to adjust the inner rotor because the inner rotor adjustment mechanism has a complex structure and is located in a closed space enclosed by the outer rotor. In addition, the complex inner rotor structure also greatly increases the difficulty of processing.

The working principle of the inner rotor cooling type high-power eddy current governor of this application is as follows:

Flexible connection of inner and outer rotors

1. The function of the linear rotation adjustment mechanism: when the outer rotor shaft 1 rotates, it drives the outer rotor skeleton disc 4 and all the outer rotor torque transmission shafts 8 to rotate. The first outer rotor moving disk 5, the first permanent magnet 52 positioned on the first outer rotor moving disk 5, the second outer rotor moving disk 7, and the second permanent magnet 72 positioned on the second outer rotor moving disk 7 are all on the outer rotor. Driven by the torque transmission shaft 8, it also rotates thereupon.

2. Magnetic connection: the rotation of the first permanent magnet 52 and the second permanent magnet 72 will drive the conductive metal disc 91 to rotate due to the magnetic force, and the conductive metal disc 91 will drive the inner rotor rotating disc 9 to rotate, thereby driving the inner rotor shaft 3 Realize the rotation, that is, realize the soft connection between the inner rotor and the outer rotor.

The adjustment of the two variable air gaps is mainly the function of the linear adjustment mechanism

1. The linear motion of the linear rotary sleeve 24: the linear motor 25 drives the linear motor shaft 25a to move left and right along the axial direction, and the connecting handle on the linear rotary sleeve 24 drives the linear rotary sleeve 24 to move left and right, thereby driving the connection The disc 21 moves linearly.

2. Adjustment of the first variable air gap 53: the linear movement of the linear rotation sleeve 24 will make the connecting plate 21 and the air gap adjusting rod 26 move linearly along the axial direction, and the air gap adjusting rod 26 will drive the first outer rotor to move The discs 5 move axially together, so that the first variable air gap 53 can be changed, thereby achieving the purpose of adjusting the first variable air gap.

3. Adjustment of the second variable air gap 73: When the first outer rotor moving disc 5 moves in the axial direction, the first sliding pin 54 on the first outer rotor moving disc 5 is positioned at the first position in the moving disc pulling disc 62. A pulling plate slides in the curved groove 62a, so that the moving plate pulling plate 62 rotates around the plane where the center pin 61 is located. Because the pull plate 62 of the moving plate is rotating, the second slide pin 74 also moves in the second pull plate curved groove 62b, so that the second outer rotor moving plate 7 can be symmetrical to the first outer rotor moving ring 6 with respect to the outer rotor symmetry. An outer rotor moving disc 5 moves axially toward or in opposite directions, so the first variable air gap 53 and the second variable air gap 73 can be enlarged or reduced synchronously and symmetrically.

a. The first variable air gap 53 and the second variable air gap 73 decrease synchronously

When the first outer rotor moving disk 5 moves axially close to the inner rotor rotating disk 9, the second outer rotor moving disk 7 also moves the same distance toward the inner rotor rotating disk 9, so that the first variable air The gap 53 and the second variable air gap 73 can be reduced by the same distance, as shown in FIG. 2 , which is a top view when the first variable air gap 53 and the second variable air gap 73 are reduced to a minimum.

b. The first variable air gap 53 and the second variable air gap 73 become larger synchronously

When the first outer rotor moving disk 5 moves axially away from the inner rotor rotating disk 9, the second outer rotor moving disk 7 also moves the same distance away from the inner rotor rotating disk 9, so that the first variable air The gap 53 and the second variable air gap 73 can be enlarged by the same distance, as shown in FIG. 3 , which is a top view when the first variable air gap 53 and the second variable air gap 73 are enlarged to the maximum.

3. Cooling function of the coolant supply and drainage system

The cooling liquid flows into the cooling liquid supply cavity 32a from the external heat exchange mechanism 33, and then flows into the inner rotor rotating disk 9 along the cooling liquid supply and discharge pipeline 31, to cool down the conductive metal disk on the inner rotor rotating disk 9, and then Then return to the cooling liquid recovery cavity 32b, cool through the external heat exchange mechanism 33, and recycle. In this way, on the one hand, a closed cooling circuit can be established inside the rotating disc of the inner rotor, avoiding the complex form of the existing mechanism that requires cooling mechanisms on the outside of the two outer rotors, and avoiding the resulting cooling and lubricating fluid Mixed problems; on the other hand, the cooling medium is completely sealed inside the inner rotor rotating disk and inner rotor shaft, which is convenient for processing, maintenance and replacement, and can be isolated from the lubrication system of each component of the inner and outer rotors to improve reliability. In addition, with the built-in metal conductive disk and the external permanent disk, the permanent disk can also be air-cooled to improve the reliability of the system.
