Technical Field

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

[0002] In the clutch structure of the reduction motor, the coupling plays a vital role. As the core component of power transmission, it is responsible for firmly connecting the two shafts to ensure smooth and efficient power transmission between the shafts. The performance of the coupling is not only directly related to the overall efficiency of the clutch structure, but also has a profound impact on the stability and service life of the clutch structure. When using the clutch structure of some existing reduction motors, there are problems such as inconvenient coupling replacement and poor lubrication. Specifically, the connection between the coupling and the transmission mechanism is tight and the design is complex, resulting in cumbersome and time-consuming operation when the coupling is severely worn due to long-term use and needs to be replaced. This feature of being difficult to disassemble not only increases maintenance costs, 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, and traditional lubrication methods, such as applying lubricating oil or using oil ring lubrication, have the problem of uneven or insufficient lubrication, which leads to increased wear of the friction surface, thereby affecting the transmission efficiency and equipment life. For this reason, a clutch structure of a reduction motor is proposed. Summary of the invention

After the support block 83 is positioned and blocked by the positioning block 56, the angle of the docking block 2 55 can be adjusted, thereby facilitating the subsequent replacement of the docking block 2 55. The second rotating shaft 52 is in contact with the box body 1 , that is, the second rotating shaft 52 can move axially and also rotate, thereby ensuring the normal operation of the second rotating shaft 52 .

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the oil circulation mechanism 7 includes a pipe 1 71 and a pipe 2 72 respectively arranged on the side of the box body 1, an oil pump 73 is arranged at one end of the pipe 1 71, and the oil pump 73 is fixedly connected to the box body 1, a pipe 3 74 is arranged at the input end of the oil pump 73, a filter 75 is arranged at one end of the pipe 3 74, the filter 75 is fixedly connected to the box body 1, and the filter 75 is fixedly connected to the pipe 2 72, and the pipe 1 71, the pipe 2 72 and the pipe 3 74 are all made of aluminum-plastic composite materials.

[0021] like 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 the connecting rod 81 is rotatably arranged with a connecting plate 82, and the outer surfaces of the two connecting plates 82 are provided with supporting blocks 83, one of the supporting blocks 83 is rotatably connected to the second connecting shaft 43, and the other supporting block 83 is in contact with the third rotating shaft 53; The displacement mechanism 9 includes a bidirectional screw rod 91 rotatably arranged on the side of the box body 1, a hand wheel 92 is arranged at one end of the bidirectional screw rod 91, a limiting rod 93 is arranged on the side of the box body 1 away from the bidirectional screw rod 91, and the two cover plates 2 are both threadedly connected to the bidirectional screw rod 91, and the two cover plates 2 are both slidably connected to the limiting rod 93.

[0022] 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 radially rotate on the inner surface of the support block 83; Another support block 83 is in contact with the rotating shaft three 53, that is, the rotating shaft three 53 can rotate radially on the inner surface of the support block 83, and at the same time, the support block 83 can move axially.

[0023] Working principle: when in use, the motor 41 is started, the output end of the motor 41 rotates to drive the connecting shaft 1 42 to rotate, and then the connecting shaft 1 42 rotates to drive the ball gear coupling 1 44 to rotate, and then the connecting shaft 2 43 rotates, and then the connecting shaft 2 43 rotates to drive the docking block 1 45 to rotate; When the docking block 1 45 and the docking block 2 55 need to be docked for transmission, the electromagnet 61 can be energized to adsorb the iron block 62. When the iron block 62 moves, the rotating shaft 2 52 can be driven to move, and then the ball gear coupling 2 54 can be driven to move through the movement of the rotating shaft 2 52, and then the rotating shaft 3 53 can be driven to move, and then the movement of the rotating shaft 3 53 can drive the docking block 2 55 to move and dock with the docking block 1 45. After the docking is completed, the docking block 1 45 can be driven to rotate the docking block 2 55, and then the docking block 2 55 can be rotated, so that the rotating shaft 3 53, the ball gear coupling 2 54, the rotating shaft 2 52 and the rotating shaft 1 51 can be rotated. In this process , start the oil pump 73, the lubricating oil liquid inside the housing 1 can enter the filter 75 through the second pipe 72, filter the debris generated by the contact and wear between the docking block 1 45 and the second docking block 55, and the filtered lubricating oil liquid can return to the housing 1 through the third pipe 74 and the first pipe 71, lubricate the docking block 1 45, the docking block 2 55, the ball gear coupling 1 44 and the ball gear coupling 2 54 and other structures to ensure the smoothness of the structural operation. At the same time, when the lubricating oil liquid circulates inside the second pipe 72, the third pipe 74 and the first pipe 71, the second pipe 72, the third pipe 74 and the first pipe 71 are made of aluminum-plastic composite materials, which is helpful to dissipate the heat of the circulating lubricating oil liquid; When the docking block 1 45 and the docking block 2 55 need to be separated, the electromagnet 61 can be powered off. At this time, the iron block 62 can be moved on the guide rod 64 to reset by the elastic force of the spring 63, and then the movement of the iron block 62 can drive the rotation shaft 2 52 to move, and then the ball gear coupling 2 54, the rotation shaft 3 53 and the docking block 2 55 can be moved and reset, completing the separation of the docking block 2 55 and the docking block 1 45; When the docking block 1 45 and the docking block 2 55 are worn out after long-term use and need to be replaced, the hand wheel 92 can be rotated, and the rotation of the hand wheel 92 can drive the bidirectional screw rod 91 to rotate, and then the rotation of the bidirectional screw rod 91 can drive the two cover plates 2 to move in opposite directions and open, thereby driving the connecting rod 81 to move, and then the movement of the connecting rod 81 can drive the connecting plate 82 to move, and then drive the support block 83 to move. In this process, when the support block 83 rotatably connected to the connecting shaft 2 43 moves, it can drive the connecting shaft 2 43 to rotate with the ball gear coupling 1 44 as the center of the circle, and then the docking block 1 45 can rotate with the ball gear coupling 1 44 as the center of the circle. At the same time, when the support block 83 contacting and cooperating with the rotating shaft 3 53 moves, the support block 83 will make an axial displacement of a certain distance on the rotating shaft 3 53. When the support block 83 contacts the positioning block 56 Afterwards, by moving the support block 83 and the connecting plate 82 and the connecting rod 81 connected thereto, the rotating shaft three 53 can be rotated with the ball gear coupling two 54 as the center, and then the docking block two 55 can be rotated with the ball gear coupling two 54 as the center. When the docking block one 45 and the docking block two 55 are rotated to the appropriate position, the hand wheel 92 can be stopped. At this time, the cover plate 2 is in an 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 an inclined upward state, so the docking block one 45 and the docking block two 55 can be disassembled and replaced. After the replacement is completed, the hand wheel 92 is reversed to reset the docking block one 45, the docking block two 55 and the related connecting structure, and then the structure can be used normally.

[0024] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
