Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a heat dissipation and lubrication connecting shaft includes a flange mounting plate 1, with bolts 2 passing through the surface of the flange mounting plate 1. One side of a universal joint 3 is fixedly connected to the inner side of the flange mounting plate 1, and a long shaft 4 is fixedly connected to the other side of the universal joint 3. The inner side of a bearing assembly 5 is fixedly connected to the surface of the long shaft 4, and a spline shaft 6 is fixedly connected to the inner side of the long shaft 4. A sleeve 7 is fitted onto the surface of the spline shaft 6. An mounting plate 8 is fixedly connected to the outer side of the bearing assembly 5, and an oil reservoir 9 is fixedly connected to the side of the mounting plate 8.

[0025] Furthermore, a number of heat dissipation holes 71 are equally spaced on the outer surface of the sleeve 7, and the inner wall of the sleeve 7 is slidably connected to the surface of the spline shaft 6.

[0026] During operation, the design of having several heat dissipation holes 71 at equal intervals on the outer surface of the sleeve 7 improves the heat dissipation effect of friction between the sleeve 7 and the spline shaft 6.

[0027] Furthermore, the bearing assembly 5 includes an outer ring 51, an inner ring 52 is provided on the inner side of the outer ring 51, ball bearings 53 are tightly fitted between the outer ring 51 and the inner ring 52, and an oil inlet pipe 54 is fixedly connected to the top of the outer ring 51.

[0028] During operation, the ball bearings 53 are tightly fitted between the outer ring 51 and the inner ring 52, which reduces the friction between the outer ring 51 and the inner ring 52.

[0029] Furthermore, both the outer ring 51 and the inner ring 52 have drainage grooves 55 on their inner walls, and the inner ring 52 has a through groove 56 inside, with the two ends of the through groove 56 connected to the drainage groove 55 and the outer wall of the drainage groove 55, respectively.

[0030] During operation, through the structural design of connecting the two ends of the through groove 56 to the outer wall of the guide groove 55 respectively, the lubricating oil flows from the inner wall of the outer ring 51 to the outer wall of the inner ring 52, and flows into the inner wall of the inner ring 52 through the through groove 56 to lubricate the surface of the long shaft 4.

[0031] Furthermore, an oil outlet pipe 10 is fixedly installed at the bottom of the oil storage tank 9, and the oil outlet pipe 10 is engaged with the surface of the bearing assembly 5.

[0032] During operation, the oil outlet pipe 10 is connected to the bearing assembly 5 by a snap-fit ​​structure, which facilitates the introduction of lubricating oil from the oil reservoir 9 into the bearing assembly 5, thus activating the lubrication effect of the bearing assembly 5.

[0033] Furthermore, one side of the sleeve 7 is fixedly connected to one end of the long shaft 4, and the mounting plate 8 is rotatably connected to the surface of the long shaft 4 through the bearing assembly 5;

[0034] During operation, the mounting plate 8 is rotatably connected to the surface of the long shaft 4, so that the mounting plate 8 is located directly above the long shaft 4, and the oil reservoir 9 on the side of the mounting plate 8 can continuously replenish the surface of the long shaft 4 with lubricating oil.

[0035] Working principle: The long shaft 4 is driven to rotate by the flange mounting plate 1 on one side of the drive device, and the spline shaft 6 drives the sleeve 7 to rotate, which in turn drives the long shaft 4 on the other side of the device to work with the flange mounting plate 1. The angle of the long shaft 4 between the two flange mounting plates 1 is automatically adjusted by the universal joint 3, and the distance between the flange mounting plates 1 is automatically adjusted by the sliding connection between the spline shaft 6 and the sleeve 7. Several heat dissipation holes 71 are opened at equal intervals on the outer surface of the sleeve 7, which improves the heat dissipation effect of the sleeve 7 and the spline shaft 6. The long shaft 4 is rotatably connected to the mounting plate 8 through the bearing assembly 5, so that the oil tank 9 is located above the bearing assembly 5, and the oil outlet pipe 10 is engaged with the surface of the oil inlet pipe 54. The lubricating oil adheres to the surface of the ball 53 through the oil inlet pipe 54 and the drainage groove 55, and then flows to the surface of the long shaft 4 through the through groove 56, which improves the heat dissipation and lubrication effect of the device.
