[0028] A limiting frame 2 is arranged inside the outer ring 1, an inner ring 3 is arranged inside the limiting frame 2, a ball 4 is movably connected to the outer side of the inner ring 3, the ball 4 penetrates and is movably connected in the limiting frame 2, and the ball 4 is movably connected to the inner wall of the outer ring 1; a sealing mechanism 5 is arranged on one side of the limiting frame 2, and a heat dissipation mechanism 6 is arranged on the outer side of the outer ring 1.

[0029] The blocking mechanism 5 includes a first U-ring groove 501, a second U-ring groove 502, a sealing ring 503, a first arc ring groove 504, an anti-slip groove 505, a steel ball 506 and a second arc ring groove 507. The first U-ring groove 501 is provided on the inner wall of the outer ring 1, and the second U-ring groove 502 is provided on the outer side of the inner ring 3. The first U-ring groove 501 and the second U-ring groove 502 are abutted with a sealing ring 503. The sealing ring 503 is arranged on one side of the limiting frame 2. The first U-ring groove 504 is provided on the inner wall of the first U-ring groove 501, and an anti-slip groove 505 is provided on the outer side of the sealing ring 503. A steel ball 506 is movably connected in the anti-slip groove 505, and the steel ball 506 is movably connected in the first arc ring groove 504. The second U-ring groove 502 is provided on the inner wall of the second arc ring groove 507, and the steel ball 506 is movably connected in the second arc ring groove 507.

[0030] In specific implementation, the cross-section of the sealing ring 503 is H-shaped to prevent the utility model from falling off from between the outer ring 1 and the inner ring 3 when working. The sealing ring 503 is abutted against the first U-ring groove 501 and the second U-ring groove 502, and multiple seals are performed between the outer ring 1 and the inner ring 3. The steel ball 506 is movably connected in the anti-slip groove 505 and abutted against the first arc ring groove 504 and the second arc ring groove 507. When the sealing ring 503 rotates in the first U-ring groove 501 and the second U-ring groove 502, the resistance during the rotation process can be reduced. The gap between the outer ring 1 and the inner ring 3 is blocked by the sealing rings 503 on both sides, thereby sealing to prevent internal lubricating oil leakage when the utility model is working.

[0031] See also Figure 1 and Figure 3 It can be seen that the heat dissipation mechanism 6 includes a heat conductive sheet 601, a heat dissipation port 602, a heat conductive ring 603, a heat dissipation hole 604, a connecting ring 605 and a fan blade 606.

If one side of the utility model is blocked during installation, air can be circulated through the heat dissipation hole 604 to accelerate the heat discharge of the heat conducting sheet 601 and the heat conducting ring 603. The heat generated by the utility model is conducted through the heat conducting sheet 601 and the heat conducting ring 603, thereby increasing the heat dissipation area. At the same time, the air circulation is accelerated with the help of external driving force, thereby assisting heat dissipation.

[0033] To sum up: before using the utility model, first install the utility model on the supporting structure, and insert the drive shaft into the inner ring 3. When the drive shaft rotates, it drives the inner ring 3 to rotate, thereby driving the ball 4 to roll between the outer ring 1 and the inner ring 3.
