Description

Technical Field

[0001] The present invention relates to the technical field of reduction motors, and more particularly to a clutch structure of a reduction motor. Background Art

[0002] In the clutch structure of a reduction motor, the coupling plays a crucial role. As the core component for power transmission, it is responsible for firmly connecting two shafts to ensure smooth and efficient power transmission between the shafts. The performance of the coupling not only directly affects the overall efficiency of the clutch structure but also profoundly impacts the stability and service life of the clutch structure.

[0003] When using the clutch structures of some existing reduction motors, there are problems of inconvenient coupling replacement and poor lubrication. Specifically, the connection between the coupling and the transmission mechanism is tight and the design is complex. When the coupling is severely worn due to long-term use and needs to be replaced, the operation process is cumbersome and time-consuming. This non-easy-to-dismantle characteristic not only increases the maintenance cost but may also affect the overall performance of the clutch structure due to improper operation. Secondly, there is contact and friction after the coupling is docked. For traditional lubrication methods, such as applying lubricating oil or using an oil ring for lubrication, there are problems of uneven or insufficient lubrication, which leads to increased wear of the friction surface, thereby affecting the transmission efficiency and the service life of the equipment. Therefore, a clutch structure of a reduction motor is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a clutch structure of a reduction motor, which can solve the problems of inconvenient coupling replacement and poor lubrication of the coupling in the clutch structures of some reduction motors, resulting in increased wear of the friction surface, reduced transmission efficiency, and shortened equipment life.

[0005] To solve the above problems, the present invention adopts the following technical solution: A clutch structure of a reduction motor includes a box body, and also includes a cover plate, a support seat, a driving mechanism, a driven mechanism, a driving mechanism, an oil liquid circulation mechanism, a transmission mechanism, and a displacement mechanism. The cover plate is slidably arranged on the upper part of the box body, and there are two cover plates. The support seat is arranged on the outer surface of the box body.

When it is necessary to replace the first docking block and the second docking block, by rotating the hand wheel, the cover plate can be opened, and the first docking block and the second docking block can be rotated to appropriate positions, and then the first docking block and the second docking block can be replaced without complex disassembly processes, thereby reducing the difficulty and time of device maintenance and alleviating the work burden of personnel;

[0016] Intelligent lubrication and heat dissipation: Through the oil circulation mechanism, sufficient lubrication of key components such as the first docking block, the first ball tooth coupling, the second ball tooth coupling, and the second docking block is achieved. This design can effectively reduce the wear of the friction surface, thereby improving the transmission efficiency and the service life of the equipment. Moreover, the first pipeline, the second pipeline, and the third pipeline are all made of aluminum-plastic composite materials, which have good heat dissipation performance. When the lubricating oil flows inside, it can effectively reduce the oil temperature. In addition, the setting of the filter can effectively filter the impurities generated by wear in the oil, further improving the stability and reliability of the equipment.

[0028] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, the driving mechanism 4 includes a motor 41 disposed on the outer surface of the box body 1. A first connecting shaft 42 is provided at the output end of the motor 41. A second connecting shaft 43 is provided on one side of the first connecting shaft 42.

A second docking block 55 is provided at one end of the third rotating shaft 53. Two positioning blocks 56 are provided on the outer surface of the third rotating shaft 53 on the side of the second docking block 55;

[0030] The driving mechanism 6 includes an electromagnet 61 disposed on the side of the box body 1. An iron block 62 is provided on one side of the electromagnet 61. The iron block 62 is rotatably connected to the second rotating shaft 52. A spring 63 is provided on the outer surface of the iron block 62.

Two buffer blocks 10 are provided on the outer surface of the iron block 62 away from the spring 63.

[0031] It should be noted that the positioning block 56 is used for positioning when the support block 83 axially moves on the third rotating shaft 53 during the angle adjustment of the second docking block 55. After the support block 83 is positioned and blocked by the positioning block 56, the angle adjustment of the second docking block 55 can be carried out, so as to facilitate the subsequent replacement of the second docking block 55;

[0032] The second rotating shaft 52 is in contact and cooperation with the box body 1, that is, the second rotating shaft 52 can axially move and can also rotate, so as to ensure the normal operation of the second rotating shaft 52.

[0033] As Figure 1 、 Figure 2 and Figure 3 shown, the oil liquid circulation mechanism 7 includes a first pipeline 71 and a second pipeline 72 respectively disposed on the side of the box body 1. A oil pump 73 is provided at one end of the first pipeline 71. The oil pump 73 is fixedly connected to the box body 1. A third pipeline 74 is provided at the input end of the oil pump 73. A filter 75 is provided at one end of the third pipeline 74. The filter 75 is fixedly connected to the box body 1. The filter 75 is fixedly connected to the second pipeline 72. The first pipeline 71, the second pipeline 72 and the third pipeline 74 are all made of aluminum-plastic composite materials.

[0034] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the transmission mechanism 8 includes two connecting rods 81 rotatably arranged at the lower part of the cover plate 2. One end of each connecting rod 81 is rotatably provided with a connecting plate 82. Support blocks 83 are arranged on the outer surfaces of the two connecting plates 82. One of the support blocks 83 is rotatably connected to the second connecting shaft 43, and the other support block 83 is in contact and cooperation with the third rotating shaft 53.

[0035] The displacement mechanism 9 includes a bidirectional lead screw 91 rotatably arranged on the side of the box body 1. A hand wheel 92 is arranged at one end of the bidirectional lead screw 91. A limiting rod 93 is arranged on the side of the box body 1 far away from the bidirectional lead screw 91. Both cover plates 2 are threadedly connected to the bidirectional lead screw 91, and both cover plates 2 are slidably connected to the limiting rod 93.

[0036] It should be noted that one of the support blocks 83 is rotatably connected to the second connecting shaft 43, that is, the second connecting shaft 43 can rotate radially on the inner surface of the support block 83.

[0037] The other support block 83 is in contact and cooperation with the third rotating shaft 53, that is, the third rotating shaft 53 can rotate radially on the inner surface of the support block 83. At the same time, the support block 83 can move axially.

[0038] Working principle: During use, start the motor 41. The rotation of the output end of the motor 41 can drive the rotation of the first connecting shaft 42. Then, the rotation of the first connecting shaft 42 can drive the rotation of the first ball tooth coupling 44, and further drive the rotation of the second connecting shaft 43. Then, the rotation of the second connecting shaft 43 can drive the rotation of the first docking block 45.

[0039] When the docking block one 45 and the docking block two 55 need to be docked for transmission, the electromagnet 61 can be powered on to adsorb the iron block 62. When the iron block 62 moves, it can drive the rotating shaft two 52 to move. Then, through the movement of the rotating shaft two 52, the ball tooth coupling two 54 can be driven to move, and further the rotating shaft three 53 can be driven to move. Then, through the movement of the rotating shaft three 53, the docking block two 55 can be driven to move and dock with the docking block one 45. After docking, by rotating the docking block one 45, the docking block two 55 can be driven to rotate. Then, through the rotation of the docking block two 55, the rotating shaft three 53, the ball tooth coupling two 54, the rotating shaft two 52 and the rotating shaft one 51 can be rotated. During this process, the oil pump 73 is started, and the lubricating oil in the box body 1 can enter the filter 75 through the pipeline two 72 to filter the debris generated by the contact wear between the docking block one 45 and the docking block two 55. The filtered lubricating oil can return to the box body 1 through the pipeline three 74 and the pipeline one 71 to lubricate the structures such as the docking block one 45, the docking block two 55, the ball tooth coupling one 44 and the ball tooth coupling two 54, ensuring the smooth operation of the structure. At the same time, when the lubricating oil flows in the pipeline two 72, the pipeline three 74 and the pipeline one 71, the pipeline two 72, the pipeline three 74 and the pipeline one 71 are made of aluminum-plastic composite materials, which helps to dissipate the heat of the flowing lubricating oil;

[0040] When the docking block one 45 and the docking block two 55 need to be separated, the electromagnet 61 can be powered off. At this time, through the elastic force of the spring 63, the iron block 62 can move on the guide rod 64 to reset. Then, through the movement of the iron block 62, the rotating shaft two 52 can be driven to move, and further the ball tooth coupling two 54, the rotating shaft three 53 and the docking block two 55 can be moved to reset, completing the separation of the docking block two 55 from the docking block one 45;

[0041] When the docking block one 45 and the docking block two 55 are severely worn after long-term use and need to be replaced, the hand wheel 92 can be rotated. The rotation of the hand wheel 92 can drive the bidirectional lead screw 91 to rotate. Then, the rotation of the bidirectional lead screw 91 can drive the two cover plates 2 to move in opposite directions and open. Furthermore, it can drive the connecting rod 81 to move. Then, the movement of the connecting rod 81 can drive the connecting plate 82 to move. Furthermore, it can drive the support block 83 to move. During this process, when the support block 83 rotatably connected to the second connecting shaft 43 moves, it can drive the second connecting shaft 43 to rotate around the ball tooth coupling one 44 as the center. Furthermore, it can make the docking block one 45 rotate around the ball tooth coupling one 44 as the center. At the same time, when the support block 83 in contact and cooperation with the third rotating shaft 53 moves, the support block 83 will have an axial displacement of a certain distance on the third rotating shaft 53. When the support block 83 contacts the positioning block 56, through the movement of the support block 83 and the connecting plate 82 and the connecting rod 81 connected thereto, the third rotating shaft 53 can be made to rotate around the ball tooth coupling two 54 as the center. Furthermore, it can make the docking block two 55 rotate around the ball tooth coupling two 54 as the center. When the docking block one 45 and the docking block two 55 rotate to the appropriate positions, the rotation of the hand wheel 92 can be stopped. At this time, the cover plate 2 is in the open state (the cover plate 2 will move a certain distance first and will not affect the rotation of the docking block one 45 and the docking block two 55), and the docking block one 45 and the docking block two 55 are in the state of tilting upward, so that the docking block one 45 and the docking block two 55 can be disassembled and replaced. After the replacement is completed, reverse the hand wheel 92 to reset the docking block one 45, the docking block two 55 and the related connection structures, and then the structure can be used normally.

[0042] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
