The working principle is as follows:
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 hinge seat 53 is fixed;
when the coupler is used at a high speed and is to be cooled, cooling liquid is conveyed into the liquid inlet tank 43 through external infusion equipment, then the cooling liquid enters the first cooling groove 41, when the cooling liquid flows through the first cooling groove 41, the interior of the outer 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, along with the gradual increase of the cooling liquid in the box body 451, 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 tank 41 is insufficient, the push plate 452 is pushed to stabilize the hydraulic pressure in the second cooling tank 42 under the action of the pressure spring 453, so that the cooling effect is stable, then the cooling liquid flows into the second cooling tank 42, cools the interior of the inner ball joint 2, and then is discharged through the outlet end of the second cooling tank 42, after the coupler is used for a period of time, because two shafts connected by the coupler are not on the same straight line, the outer ball joint 3 deflects relative to the inner ball joint 2, part of the spherical surface of the inner ball joint 2 is exposed outside, and the wiping rod 51 is positioned outside the part of the spherical surface; the electromagnetic slider 56 is initially located on one side of the electromagnetic slide rail 55 close to the shaft body 1, then the electromagnetic slider 56 is activated, so that the electromagnetic slider 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 activated, the output end of the electric push rod 54 drives the wiping rod 51 to approach to the exposed spherical surface of the inner ball-and-tooth joint 2 through the electromagnetic slider 56 and the connecting rod 57, when the wiping rod 51 moves to the joint of the exposed spherical surface and the outer ball-and-tooth joint 3, the electromagnetic slider 56 is activated again, the electromagnetic slider 56 moves in the direction close to the shaft body 1, so that the wiping rod 51 is attached to the exposed spherical surface of the inner ball-and-tooth joint 2, meanwhile, the electric push rod 54 is activated to contract, meanwhile, the electromagnetic slider 56 moves to keep the wiping rod 51 attached to the inner ball-and-tooth joint 2 all the time, when the wiping rod 51 moves, the exposed spherical surface of the inner ball-and-tooth joint 2 is wiped, metal chips on the metal chips are scraped, and then sprayed on the wiping rod 51 and dropped on the metal chips are sprayed through the nozzle 58 after the cooling liquid enters the second cooling groove 42.
