Description

Technical Field

[0001] This utility model relates to the field of permanent magnet adjustment technology, specifically a horizontal speed-regulating permanent magnet coupler. Background Technology

[0002] A permanent magnet coupler is a device that transmits torque between a motor and a load through a rotating magnetic field between a conductor and a permanent magnet. It enables rotation between the motor and the load without mechanical connection. A permanent magnet speed controller adds an adjustment mechanism to the permanent magnet coupler to adjust the relative position of the permanent magnet rotor and the conductor rotor along their axes, thereby changing the effective part of the coupling between them and thus changing the torque transmitted between them. This achieves repeatable, adjustable, and controllable output torque and speed, achieving the purpose of speed regulation and energy saving.

[0003] Existing adjustment mechanisms adjust the distance between the load and the motor by moving the load and the motor, thereby changing the gap between the conductor rotor and the permanent magnet rotor. This adjustment method often requires a lot of manpower and has a complex structure. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing adjustment mechanism in the prior art, which adjusts the distance between the load and the motor by moving the load and the motor, thereby changing the gap between the conductor rotor and the permanent magnet rotor. This adjustment method often requires a lot of manpower and has a complex structure.

[0005] A horizontal speed-regulating permanent magnet coupler is proposed, comprising a fixed base, a conductor rotor, a permanent magnet rotor, an axial moving mechanism, and a moving device. The conductor rotor and the permanent magnet rotor are located above the fixed base and positioned in the middle of the fixed base. Both the conductor rotor and the permanent magnet rotor are connected to the fixed base. The conductor rotor is sleeved on the permanent magnet rotor, and there is an air gap between the conductor rotor and the permanent magnet rotor. The axial moving mechanism is located on one side of the permanent magnet rotor and is vertically arranged on the fixed base. The moving device is located above the axial moving mechanism and is connected to the permanent magnet rotor.

[0006] In this utility model's technical solution, when the coupler's rotational speed needs adjustment, the electric push rod is activated to raise the lifting rod until the auxiliary wheel contacts the outer wall of the gear ring. Then, the electric push rod and electromagnet are deactivated. After the electromagnet is deactivated, the second spring pushes the sliding plate and the insertion rod upwards. As the gear ring rotates counter-clockwise, the top of the insertion rod inserts into a pre-set groove in the gear ring and blocks the moving block. The gear ring continues to rotate counter-clockwise. During this rotation, the moving block moves from one end of the guide groove to the other until the ball bearing and the top of the insertion rod are inserted into the limiting hole. At this point, the rotation direction of the load shaft can be adjusted as needed. This is especially important when the air gap between the permanent magnet rotor and the conductor rotor needs to be increased. Rotating the load shaft clockwise reduces the air gap between the permanent magnet rotor and the conductor rotor. Rotating the load shaft counterclockwise adjusts the air gap between the permanent magnet rotor and the conductor rotor to the required distance. Then, the electromagnet is activated to attract the sliding plate downwards. As the sliding plate moves downwards, the top of the insertion rod and the ball will disengage from the limit hole and break contact with the moving block. When the stop rod is reinserted into the card hole, the gear ring can rotate synchronously with the load shaft. This solves the problem mentioned in the technical background that the existing adjustment mechanism adjusts the distance between the load and the motor by moving the load and the motor, thereby changing the gap between the conductor rotor and the permanent magnet rotor. This adjustment method often requires a lot of manpower and has a complex structure.

[0007] In a preferred embodiment of the present invention, the conductor rotor is a cylindrical copper conductor, and a motor shaft is provided on one side of the conductor rotor. The conductor rotor is connected to the motor shaft, and the motor shaft is rotatably connected to the bearing seat. Therefore, when the motor shaft rotates, it can drive the conductor rotor to rotate together.

[0008] In a preferred embodiment of the present invention, a load shaft is provided on one side of the permanent magnet rotor, and an end cap is provided at the end of the load shaft. The permanent magnet rotor is connected to the end cap, and a moving device is provided inside the load shaft. When the conductor rotor rotates, the load can be driven to rotate synchronously through the permanent magnet rotor and the load shaft.

[0009] In a preferred embodiment of the present invention, the moving device comprises a gear ring, gears, a rotating rod, a moving block, a drawstring, a stop bar, a first spring, and a housing. The gear ring is sleeved on the load shaft. There are three gears, all located inside the gear ring and connected to the load shaft. The gears mesh with the gear ring. Each gear has a rotating rod on one side. The moving block is located outside the gear ring and slidably connected to it. There are two stop bars, each located on one side of the gear ring. The housing is located inside the gear ring. One end of each stop bar is located inside the housing. Both stop bars are connected to the moving block via a drawstring. The first spring is located in the middle of the two stop bars, with both ends abutting against the two stop bars. When it is necessary to adjust the air gap between the conductor rotor and the permanent magnet rotor, the rotating rod can be rotated by the gears. When the rotating rod rotates, it can drive the permanent magnet rotor to slide.

[0010] In a preferred embodiment of the present invention, the gear ring is provided with a guide groove, and the moving block is disposed in the guide groove. When the moving block slides inside the gear ring, the guide groove can guide the moving block.

[0011] In a preferred embodiment of the present invention, the gear ring is provided with two limiting holes corresponding to the insertion rod in the axial moving mechanism. When the insertion rod is inserted into the limiting hole, the limiting hole can restrict the position of the gear ring.

[0012] In a preferred embodiment of the present invention, the end of the rotating rod is provided with a thread, and the end of the rotating rod passes through the load shaft and is connected to the permanent magnet rotor. When the rotating rod rotates, it can drive the permanent magnet rotor to slide through the thread.

[0013] In a preferred embodiment of the present invention, the load shaft is provided with multiple locking holes corresponding to the stop lever. After the stop lever is inserted into the locking holes, the gear ring and gear can no longer rotate.

[0014] In a preferred embodiment of the present invention, the axial movement mechanism includes a fixed cylinder, a lifting rod, an electric push rod, an electromagnet, a second spring, a sliding plate, a connecting rod, a ball bearing, and auxiliary wheels. The fixed cylinder is located below the gear ring and connected to a fixed base. The lifting rod is slidably disposed inside the fixed cylinder. The electric push rod is located below the lifting rod. The electromagnet is disposed inside the lifting rod. A second spring is vertically disposed on both sides of the electromagnet. The sliding plate is located above the electromagnet and slidably connected to the lifting rod. A connecting rod is vertically connected to both ends of the sliding plate. A ball bearing is connected to the top of each connecting rod. Two auxiliary wheels are disposed at the top of the lifting rod, and the two auxiliary wheels are respectively disposed on both sides of the two lifting rods. When the lifting rod moves upward, the electric push rod can be stopped after the auxiliary wheel at the top of the lifting rod contacts the outer wall of the gear ring, thereby preventing the top of the lifting rod from directly hitting the outer wall of the gear ring and causing the lifting rod to break.

[0015] The advantages of this utility model compared with the prior art are: In use, this invention can drive the conductor rotor to slide on the end cover through the axial moving mechanism and moving device, thereby adjusting the air gap between the conductor rotor and the permanent magnet rotor, and thus adjusting the rotational speed between the conductor rotor and the permanent magnet rotor.

Detailed Implementation

[0017] The following will refer to the appendix in the embodiments of this utility model. Figure 1-15 The technical solutions in the embodiments of this utility model will be described in detail below.

[0018] like Figure 1-4 As shown, a horizontal speed-regulating permanent magnet coupler includes a fixed base 1, a conductor rotor 2, a permanent magnet rotor 3, an axial moving mechanism 4, and a moving device 5. The conductor rotor 2 and the permanent magnet rotor 3 are located above the fixed base 1, and the conductor rotor 2 and the permanent magnet rotor 3 are positioned in the middle of the fixed base 1.

[0019] like Figure 1-4 As shown, the conductor rotor 2 is a cylindrical copper conductor, and a motor shaft 6 is provided on one side of the conductor rotor 2. The motor shaft 6 is rotatably connected to the fixed base 1. One end of the motor shaft 6 is connected to the conductor rotor 2. The conductor rotor 2 is sleeved on the permanent magnet rotor 3. An end cover 71 and a load shaft 7 are provided on one side of the permanent magnet rotor 3.

[0020] like Figure 1-4 As shown, the load shaft 7 is rotatably connected to the fixed base 1, and the end cover 71 is located in the middle position between the permanent magnet rotor 3 and the load shaft 7. The end cover 71 is connected to the load shaft 7 by a spline, and the permanent magnet rotor 3 is slidably connected to the end cover 71. Therefore, the permanent magnet rotor 3 can slide along the length direction of the load shaft 7 to adjust the air gap between the permanent magnet rotor 3 and the conductor rotor 2, thereby adjusting the speed.

[0021] like Figure 1-4 As shown, the axial moving mechanism 4 is located below the load shaft 7 and is vertically connected to the fixed base 1. The moving device 5 is located above the axial moving mechanism 4 and connected to the load shaft 7, and the moving device 5 is connected to the axial moving mechanism 4.

[0022] like Figure 5-12 As shown, the moving device 5 includes a gear ring 51, a gear 52, a rotating rod 53, a moving block 54, a draw rope 55, a stop bar 56, and a first spring 57. The gear ring 51 is sleeved on the load shaft 7 and is rotatably connected to the load shaft 7. When the load shaft 7 remains stationary, the gear ring 51 can rotate.

[0023] like Figure 5-12 As shown, similarly, when the gear ring 51 remains stationary, the load shaft 7 can rotate. There are three gears 52, and all three gears 52 are located inside the gear ring 51. All three gears 52 are rotatably connected to the load shaft 7, and each gear 52 meshes with the gear ring 51.

[0024] like Figure 5-12 As shown, when the load shaft 7 drives the gear 52 to rotate while the gear ring 51 remains stationary, the gear 52 will rotate under the drive of the load shaft 7. Each gear 52 has a rotating rod 53 on one side, which is rotatably connected to the inside of the load shaft 7, and one end of the rotating rod 53 is welded to the side of the gear 52.

[0025] like Figure 5-12 As shown, the other end of the rotating rod 53 is threaded. The threaded end of the rotating rod 53 passes through the end cover 71 and is threadedly connected to the permanent magnet rotor 3. When the gear 52 rotates, it can drive the rotating rod 53 to rotate together. The end of the rotating rod 53 is threadedly connected to the permanent magnet rotor 3, and the permanent magnet rotor 3 is slidably connected to the end cover 71.

[0026] like Figure 5-12 As shown, when the gear 52 drives the rotating rod 53 to rotate, the rotating rod 53 can adjust the position of the permanent magnet rotor 3 by sliding through the thread. A groove is provided on the outer wall of the gear ring 51, and the moving block 54 is set in the groove on the outer wall of the gear ring 51. Guide grooves 8 are provided on the side walls on both sides of the groove, and the moving block 54 is slidably connected in the guide grooves 8.

[0027] like Figure 5-12 As shown, there are two stop levers 56, which are respectively set on both sides of the gear ring 51. The gear ring has grooves at the positions of the two stop levers, and a housing 9 is provided in the grooves. The two stop levers are respectively set at both ends of the housing 9, and both stop levers 56 are slidably connected to the gear ring 51.

[0028] like Figure 5-12 As shown, both stop levers 56 are connected to the moving block 54 via drawstrings 55. The drawstrings 55 are located inside the toothed ring, and the two ends of the drawstrings 55 are respectively attached to the stop levers 56 and the moving block 54. The first spring 57 is located in the middle of the two stop levers 56, and the two ends of the first spring 57 are respectively in contact with the two stop levers 56.

[0029] like Figure 5-12 As shown, when the moving block 54 slides in the direction of the guide groove 8, the moving block 54 will pull the two stop levers 56 back into the toothed ring 51 through the draw rope 55. When the stop levers 56 move into the toothed ring 51, the two stop levers 56 will squeeze the first spring 57, thereby causing the first spring 57 to flip over, deform and store force.

[0030] like Figure 5-12 As shown, when the moving block 54 is released, the two stop levers 56 will be pushed outward by the first spring 57. During the process of the stop levers 56 being pushed outward by the first spring 57, the stop levers 56 will also pull the moving block 54 back to its original position through the draw rope 55. The load shaft 7 is provided with multiple locking holes 72 corresponding to the stop levers 56.

[0031] like Figure 5-12 As shown, when the stop lever 56 is inserted into the buckle, the load shaft 7 will drive the gear ring 51 to rotate synchronously. When the stop lever 56 is pulled out by the pull rope, the gear ring 51 can remain stationary while the load shaft 7 rotates.

[0032] like Figure 13-15 As shown, the axial movement mechanism 4 includes a fixed cylinder 41, a lifting rod 42, an electric push rod 43, an electromagnet 44, a second spring 45, a sliding plate 46, a plug-in rod 47, a ball bearing 48, and an auxiliary wheel. The fixed cylinder 41 is vertically arranged below the gear ring and is connected to the fixed base by screws.

[0033] like Figure 13-15 As shown, the lifting rod 42 is slidably connected inside the fixed cylinder 41, and the electric push rod 43 is vertically arranged inside the fixed cylinder 41. The electric push rod 43 is fixedly connected to the bottom plate of the fixed cylinder 41 by screws. The electric push rod 43 is located below the lifting rod 42, and the output end of the electric push rod 43 is connected to the bottom plate of the lifting rod 42.

[0034] like Figure 13-15 As shown, the electromagnet 44 is installed inside the lifting rod 42 and is fixedly connected to the center of the bottom plate of the lifting rod 42 by screws. A second spring 45 is vertically installed on both sides of the electromagnet 44. The sliding plate 46 is vertically installed above the electromagnet 44 and is slidably connected to the inner wall of the lifting rod 42.

[0035] like Figure 13-15 As shown, the second spring 45 is vertically arranged below the sliding plate 46, and the upper and lower ends of the second spring 45 are respectively connected to the sliding plate 46 and the lifting rod 42. Both ends of the sliding plate 46 are provided with a vertically inserted rod 47, and the bottom end of the inserted rod 47 is welded to the sliding plate 46.

[0036] like Figure 13-15 As shown, each plug rod 47 has a ball bearing 48 embedded at its top end. The ball bearing 48 can rotate freely inside the plug rod 47. The top end of the lifting rod 42 is rotatably connected to two auxiliary wheels, which are respectively set on both sides of the plug rod 47.

[0037] like Figure 13-15As shown, a limiting hole 10 is provided at the position of each of the two plug rods 47 on the gear ring. When the plug rod 47 is inserted into the limiting hole 10, the plug rod 47 can restrict the position of the gear ring.

[0038] The motion process in this embodiment is as follows: When the coupler is working, the motor shaft 6 will drive the conductor rotor 2 to rotate. When the conductor rotor 2 rotates, it will drive the load to rotate through the permanent magnet rotor 3 and the load shaft 7. Then, when speed adjustment is required, the electric push rod 43 can be activated to lift the lifting rod 42 upward.

[0039] When both auxiliary wheels 49 are in contact with the outer wall of the gear ring 51 and the auxiliary wheels 49 are rotated by the gear ring 51, the electromagnet 44 can be closed. At this time, the second spring 45 will push the sliding plate 46 and the plug rod 47 outward, and then the ball 48 and the top of the plug rod 47 will be inserted into the preset groove of the gear ring 51. At this time, the plug rod 47 will block the moving block, and the ball 48 will be in contact with the inner wall of the groove of the gear ring 51. Then the load shaft 7 and the gear ring 51 will continue to rotate.

[0040] As the gear ring 51 and load shaft 7 continue to rotate, the moving block 54 moves along the direction of the guide groove 8. When the moving block 54 moves to the end of the guide groove 8 and the insertion rod abuts against the gear ring 51 through the moving block 54, thus preventing the gear ring 51 from rotating, the top of the insertion rod 47 will also move to the position of the limiting hole 10. Then, the ball 48 and the insertion rod 47 will be pushed upward again by the second spring 45 and the sliding plate 46 until the top of the ball 48 and the insertion rod 47 are inserted into the interior of the limiting hole 10. This restricts the position of the gear ring 51, preventing it from rotating. When the load shaft 7 continues to rotate, it can drive the permanent magnet rotor 3 to slide through the gear 52 and the rotating rod 53, thereby adjusting the air gap between the permanent magnet rotor 3 and the conductor rotor 2.

[0041] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
