[0022] The specific implementation method is as follows: when using the utility model, the inner shaft 4 can be rotated to drive the rotating cam 211 installed inside to rotate. The rotating cam 211 drives the multiple sets of rotating shafts 213 on the outer wall to rotate while rotating. After the multiple sets of rotating shafts 213 rotate at the same time, the rotation speed of the rotating inner shaft 4 can be enhanced. The rotating cam 211 is assembled inside the rotating inner groove 214. While the rotation stability is guaranteed, the rotation efficiency of the rotating inner shaft 4 is accelerated. The first flange 1 and the second flange 3 simultaneously protect the outer wall of the rotating inner shaft 4, further enhancing the use strength of the entire component.

[0023] As attached Figure 4 As shown, the utility model provides a high-strength automobile wheel hub bearing, which also includes an oil injection assembly 22. The oil injection assembly 22 includes: an injection hole 222 and a sealing installation bolt 221.

After the multiple sets of rotating shaft rods 213 rotate at the same time, the rotation speed of the rotating inner shaft 4 can be enhanced. Before the rotating inner shaft 4 is rotated and used, the inside of the rotating inner shaft 4 can be filled with oil through the four sets of injection holes 222. After the first flange 1 and the second flange 3 are filled with oil, the rotating shaft rods 213 installed inside can accelerate lubrication. The four sets of injection holes 222 are filled with oil at the same time, which further improves the oil filling efficiency and further enhances the uniformity of the internal oil filling of the component, effectively avoiding the use efficiency of the component caused by uneven oil filling, and after the internal lubricating oil of the component is scaled after use, clean water can be injected through the four sets of injection holes 222 to clean the internal oil scale.
