[0026] In the embodiment, the contact ball 313 is slidingly connected between the ball bottom contact groove 311 and the ball top contact groove 312. The contact ball 313 is made of high-hardness ceramic material. The cooperation of the ball bottom contact groove 311, the ball top contact groove 312 and the contact ball 313 can improve the load capacity of the bearing. The contact ball 313 made of high-hardness ceramic material has the advantages of high melting point, high hardness, high wear resistance, oxidation resistance and the like, thereby prolonging the service life of the contact ball 313. Meanwhile, the cooperation of the sealing ring 314, the clamping sealing ring 317 and the annular clamping groove 318 can seal the outside of the bearing outer ring 1 and the bearing inner ring 2, prevent the lubricating oil inside the bearing outer ring 1 and the bearing inner ring 2 from leaking outwards, and reduce the wear of the contact ball 313, thereby improving the service life of the bearing.

[0027] Further, the clamping sealing ring 317 is clamped with the annular clamping groove 318. The rubber sound insulation pad 316 can reduce noise, thereby improving the applicability of the device.

[0028] When the device is in use, first fix the bearing inner ring 2 to the external rotating shaft, then connect the bearing outer ring 1 to the steel belt, and then it can be used. By setting up double-row angular contact balls 313, the bearing can have better load capacity, and the contact balls 313 are made of high-hardness ceramic material, which can make the contact balls 313 have good advantages such as high melting point, high hardness, high wear resistance, and oxidation resistance, thereby extending the service life of the contact balls 313.

At the same time, by setting the rubber sound insulation pad 316, a better noise reduction effect can be achieved, thereby increasing the applicability of the device. Example 2

[0029] On the basis of Example 1, the preferred embodiment of the double-row angular contact groove steel strip bearing provided by the present invention is as follows: Figures 1 to 5 As shown: the heat dissipation mechanism 32 includes an annular groove 321 opened on the outer wall of the bearing outer ring 1, a steel belt contact groove 322 is opened on the inner wall of the annular groove 321, a guide block 323 is fixedly connected to the inner wall of the annular groove 321, and a heat dissipation hole 324 is opened on the outer side of the bearing outer ring 1.

Through the cooperation of the annular groove 321, the steel belt contact groove 322, the guide blocks 323, and the heat dissipation holes 324, when the bearing outer ring 1 rotates, the guide blocks 323 can rotate synchronously, so that the hot air inside the annular groove 321 can be discharged to the outside through the heat dissipation holes 324, thereby achieving a heat dissipation effect and preventing the steel belt from being damaged by the heat generated by the friction between the steel belt and the steel belt contact groove 322.

[0031] Furthermore, the heat dissipation holes 324 are inclined holes, which can better guide the hot air inside the bearing outer ring 1 to the outside, thereby achieving a better heat dissipation effect.

[0032] When the steel belt needs to be connected, the steel belt only needs to be placed manually in the steel belt contact groove 322 to complete the connection operation. When the bearing outer ring 1 rotates, the guide block 323 fixedly connected to the inner wall of the annular groove 321 can rotate synchronously, so that the hot air inside the annular groove 321 can be blown outward. Then, under the action of the heat dissipation holes 324, the hot air inside the bearing outer ring 1 can be discharged outward, which can prevent the steel belt and the steel belt contact groove 322 from generating excessive heat due to friction and causing damage to the steel belt.
