Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet transmission equipment, in particular to a liquid-cooled mobile base type permanent magnet speed regulator. Background Art

[0002] Permanent magnet speed regulation is one of the national key energy-saving technology promotion projects. It is a transmission method that uses magnetic transmission, which is different from traditional transmission. The main adjustment method is to 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, that is, to change the torque transmitted between the two. It can achieve repeatable, adjustable and controllable output torque and speed, thereby achieving the purpose of speed regulation and energy saving. The characteristics of permanent magnet speed regulation are simple in structure, reliable in operation, and energy saving and consumption reduction, and are well applied in modern industry.

[0003] Chinese patent publication number CN103762823A discloses a water-cooled permanent magnet speed regulator, comprising a housing, a conductor rotor arranged on a power input shaft, and a permanent magnet rotor arranged on a drive output shaft and corresponding to the conductor rotor. The regulator is characterized in that a cooling water box is provided on the inner wall of the housing directly above the conductor rotor, the cooling water box is connected to an external cooling water source through a water inlet hole of the housing, and a water leakage hole is provided at the bottom of the cooling water box; and a housing water outlet hole is provided at the bottom of the housing.

[0004] However, when the above-mentioned device cools the conductor rotor, cooling water drips onto the conductor rotor through the leaking holes to cool the conductor rotor. However, due to the centrifugal force of the high-speed rotation of the conductor rotor, the cooling water dripping onto the conductor rotor has difficulty penetrating into the center of the conductor rotor, resulting in uneven cooling of the conductor rotor. The outer edge of the conductor rotor is well covered by the cooling water, thereby achieving a good cooling effect. However, the inner part near the rotating center is not cooled well because little cooling water reaches it, resulting in poor cooling effect and insufficient heat dissipation. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following is a combination of the embodiments of the present invention Figure 1-26 , the technical solutions in the embodiments of the present invention are described in detail.

[0019] like Figure 1-6 As shown, a liquid-cooled movable base type permanent magnet speed regulator includes a permanent magnet rotor 1, a fixed base 2, a cooling device 3, a circulation component 4, a clamping device 5 and a moving device 6. The permanent magnet rotor 1 is arranged above the fixed base 2, a load shaft 11 is provided on one side of the permanent magnet rotor 1, and a conductor rotor 7 is provided on the other side of the permanent magnet rotor 1.

[0020] like Figure 1-6 As shown, the permanent magnet rotor 1 is covered on the conductor rotor 7, and a drive motor 71 is provided on the other side of the conductor rotor 7. The output shaft of the drive motor 71 is connected to the conductor rotor 7. When the drive motor 71 drives the conductor rotor 7 to rotate, the conductor rotor 7 can drive the permanent magnet rotor 1 to rotate.

[0021] like Figure 1-6 As shown, the permanent magnet rotor 1 is fixedly connected to the load shaft 11 by bolts, and the permanent magnet rotor 1 is rotatably connected to the fixed base 2 through the load shaft 11. A heat conductive cover 8 is provided on the permanent magnet rotor 1, and the end of the load shaft 11 passes through a through hole preset at the axial position of the heat conductive cover 8 and is then connected to the permanent magnet rotor 1.

[0022] like Figure 1-6As shown, the heat-conducting cover 8 is connected to the load shaft 11 through a pin key, so when the load shaft drives the permanent magnet rotor 1 to rotate, the heat-conducting cover 8 will rotate synchronously with the permanent magnet rotor 1. Fifteen groups of heat-dissipating fins 81 are provided on the heat-conducting cover 8. Each group of heat-dissipating fins 81 is welded to the heat-conducting cover 8, and a group of cooling devices 3 is provided between every two adjacent groups of heat-dissipating fins 81, for a total of fifteen groups of heat-dissipating devices.

[0023] like Figure 1-6 As shown, each set of heat dissipation devices is connected to the heat conductive cover 8. The heat conductive cover 8 and the heat dissipation fins 81 are made of aluminum. The open end of the heat conductive cover 8 is connected to the permanent magnet rotor 1 and the circulation component 4. One end of the heat conductive cover 8 is provided with an opening, and the permanent magnet rotor 1 enters the interior of the heat conductive cover 8 from the opening at the end of the heat conductive cover 8.

[0024] like Figure 1-6 As shown, after the heat conductive cover 8 is placed on the permanent magnet rotor 1, the opening ends of the permanent magnet rotor 1 and the heat conductive cover 8 both face the conductor rotor 7. After the heat conductive cover 8 is placed on the permanent magnet rotor 1, the outer wall of the permanent magnet rotor 1 will contact the inner wall of the heat conductive cover 8.

[0025] like Figure 1-6 As shown, when the permanent magnet rotor 1 generates heat, the heat will be absorbed by the heat-conducting cover 8, and then the cooling component will dissipate the heat from the heat-conducting cover 8 to reduce the temperature of the permanent magnet rotor 1. The circulation component 4 is arranged below the cooling device 3, and the circulation component 4 is connected to the fixing seat 2. After the coolant inside the cooling device 3 dissipates the heat from the heat-conducting cover 8, the temperature of the coolant will rise.

[0026] like Figure 1-6 As shown, the heated coolant will be collected by the circulation component 4 for cooling, and then the circulation component 4 will sprinkle the cooled coolant on the heat conductive cover 8 again, thereby cooling the heat conductive cover 8 and the permanent magnet rotor 1. The clamping device 5 is arranged below the fixed seat 2, and the moving device 6 is located below the clamping device 5, and the clamping device 5 is slidably connected to the moving device 6 before the fixed seat 2 is placed on the clamping device 5.

[0027] like Figure 1-6 As shown, the clamping device 5 can then limit the position of the fixed base 2. After the clamping device 5 clamps and fixes the fixed base 2, the movable device 6 can adjust the position of the fixed base 2 and the permanent magnet rotor 1, thereby adjusting the air gap between the permanent magnet rotor 1 and the conductor rotor 7.

[0031] like Figure 7-10 As shown, in order to prevent the end of the conduit 92 from being thrown out from the first water collecting box 31 when the heat conductive cover 8 rotates, the second water collecting box 34 and the third water collecting box 35 are arranged above the heat conductive cover 8 in the axial direction of the heat conductive cover 8, and the second water collecting box 34 and the third water collecting box 35 are respectively located at both ends of the water diversion box 33.

[0033] like Figure 7-10 As shown, two groups of water outlet holes are provided on the side walls of both sides of the first water collecting box 31, the second water collecting box 34 and the third water collecting box 35 (the first water collecting box 31, the water distribution box 33, the second water collecting box 34 and the third water collecting box 35 are preferably made of high-temperature resistant plastic), and each water outlet is threadedly connected to an atomizing nozzle 36.

[0034] like Figure 7-10 As shown, when the coolant enters the first water collecting box 31, the second water collecting box 34 and the third water collecting box 35, it can be sprayed out through the atomizing nozzle 36, and the atomizing nozzle 36 will spray the coolant on the heat dissipation fins 81 to cool the heat dissipation fins 81.

[0035] like Figure 7-10As shown, after the coolant cools down the heat dissipation fins 81, it will be thrown off the heat dissipation fins 81 by the centrifugal force of the heat conduction cover 8. The thrown-off coolant will hit the inner wall of the waterproof shell 41 and will ultimately be collected by the circulation component 4.

[0036] As Figure 11-15 shown, the circulation component 4 includes a waterproof shell 41, a water baffle 42, balls 43, a filter plate 44, a water tank 45, a liquid pump 46 and a water supply module 9.

The water baffle 42 is provided with a plurality of openings, and threaded holes corresponding to the openings are provided on the outer wall of the heat conduction cover 8. Each threaded hole is provided with a bolt.

[0039] As Figure 11-15 shown, the lower end of the bolt passes through the opening on the water baffle 42 and is threadedly connected to the threaded hole of the heat conduction cover 8, thereby connecting the water baffle 42 and the heat conduction cover 8 together. The lower end of the water baffle 42 is connected to the heat conduction cover 8. The top end of the water baffle 42 is slidably arranged inside the waterproof shell 41, and the water baffle 42 is connected to the waterproof shell 41 by a clamping method.

[0040] As Figure 11-15 shown, a plurality of balls 43 are provided at the contact position between the water baffle 42 and the waterproof shell 41. When the water baffle 42 rotates following the heat conduction cover 8, the balls 43 will rotate synchronously, thereby reducing the friction between the water baffle 42 and the waterproof shell 41 and reducing wear. <{}

[0041] As Figure 11-15 shown, both the waterproof shell 41 and the water baffle 42 are made of aluminum. The balls 43 are made of high-temperature resistant plastic. The filter plate 44 is arranged inside the waterproof shell 41, and the filter plate 44 is located below the heat conduction cover 8. The filter plate 44 is made of aluminum and is welded to the waterproof shell 41.

[0042] As Figure 11-15As shown, when in use, the filter can be placed on the filter plate 44 to filter the coolant after heat dissipation. The water tank 45 is located inside the waterproof shell 41 and is arranged below the filter plate 44. The water tank 45 is made of high-temperature resistant plastic.

The water supply module 9 is set in the middle position between the fixing seat 2 and the liquid pump 46, and the water supply module 9 is connected to the load shaft 11.

Therefore, when the water collecting ring 93 rotates following the load shaft 11, the fixed shell 94 will remain stationary.

[0049] like Figure 16-20As shown, the gap between the fixed shell 94 and the water collecting ring 93 is provided with a sealing ring and is sealed by a felt ring sealing method, so as to prevent the coolant from entering the interior of the water collecting ring 93 and leaking from the gap between the fixed shell 94 and the water collecting ring 93.
