Working principle:
when in use, the two outer spherical tooth joints 3 on the coupler are connected with the shaft body to be transmitted, so that the exposed spherical surface is close to the wiping rod 51, and then the hinging seat 53 is fixed;
when the coupling is used at a high speed, when the coupling is to be cooled, the external infusion device is used for conveying cooling liquid into the liquid inlet box 43, then the cooling liquid enters the first cooling groove 41, when the cooling liquid flows through the first cooling groove 41, the inside of the external ball tooth joint 3 is cooled, the cooling liquid is discharged through the first cooling groove 41 and then enters the box body 451 through the connecting pipe 46, and as the cooling liquid in the box body 451 is gradually increased, the cooling liquid pushes the push plate 452 to compress the pressure spring 453, and meanwhile, the cooling liquid enters the second cooling groove 42; when the pressure of the first cooling groove 41 is insufficient, under the action of the pressure spring 453, the push plate 452 is pushed to stabilize the hydraulic pressure in the second cooling groove 42, the cooling effect is stable, then the cooling liquid flows into the second cooling groove 42 to cool the interior of the inner spherical tooth joint 2, and then the cooling liquid is discharged through the outlet end of the second cooling groove 42, when the coupling is used for a period of time, because the two shafts connected by the coupling are not on the same straight line, the outer spherical tooth joint 3 deflects relative to the inner spherical tooth joint 2, part of the spherical surface of the inner spherical tooth joint 2 is exposed, and the wiping rod 51 is positioned outside the part of the spherical surface; the initial state of the electromagnetic slide block 56 is positioned at one side of the electromagnetic slide rail 55 close to the shaft body 1, then the electromagnetic slide block 56 is started, so that the electromagnetic slide block 56 moves to one end of the electromagnetic slide rail 55 far away from the shaft body 1, then the electric push rod 54 is started, the output end of the electric push rod 54 drives the scraping rod 51 to approach the exposed spherical surface of the inner spherical tooth joint 2 through the electromagnetic slide block 56 and the connecting rod 57, when the scraping rod 51 moves to the joint of the exposed spherical surface and the outer spherical tooth joint 3, the electromagnetic slide block 56 is started again, so that the scraping rod 51 is attached to the exposed spherical surface of the inner spherical tooth joint 2, meanwhile, the electric push rod 54 is started, the electromagnetic slide block 56 moves, the scraping rod 51 is always attached to the inner spherical tooth joint 2, metal scraps on the inner spherical tooth joint 2 are scraped off when the scraping rod 51 moves, after the cooling liquid passes through the second cooling groove 42, the opening end of the second cooling groove 42 is discharged, and then the metal scraps on the scraping rod 51 are sprayed on the scraping rod through the nozzle 58.
