[0027] In this embodiment, the shaft ring 11 is provided, and a portion of the surface of the shaft ring 11 is in an inclined state, which can cooperate with the inclined surface of the inner wall of the seat ring 12, so that the shaft ring 11 and the seat ring 12 can be assembled into a whole. The shaft ring 11 is provided with a mounting groove 13 and a mounting groove 2 15, and the mounting groove 13 and the mounting groove 2 15 are both provided at intervals, so that the roller 14 and the roller 2 16 installed in the mounting groove 13 and the mounting groove 2 15 are also in a spaced state, and there will be no contact between them, thereby achieving the purpose of reducing friction damage. At the same time, there is no need to install a spacer block, which makes the installation efficiency of roller 14 and roller 2 16 higher. An oil filling groove 17 is provided, and the oil filling groove 17 is connected to the annular groove 18, so that the oil injected at the oil filling groove 17 can be transmitted through the annular groove 18, and then can seep out from the oil outlet groove 106 in the installation groove 13. Similarly, the oil filling groove 2 19 is connected to the annular groove 2 101, so that the annular groove 2 101 can transmit the lubricating oil to the oil outlet groove 106 in the roller 14, thereby lubricating the roller 14 and roller 2 16.

[0028] Example 2

[0029] like Figures 1-7As shown, the shaft ring 11 is sleeved with bolt 102, and the bolt 102 is threadedly connected to the shaft ring 11. The shaft ring 11 is sleeved with bolt 2 103, and the bolt 2 103 is threadedly connected to the shaft ring 11. A washer 104 is provided at one end of the shaft ring 11, and a bolt 3 105 is sleeved inside the washer 104, and the bolt 3 105 is slidingly connected to the washer 104.
