[0029] Outer sealing lip 2 is arranged along the outer wall of outer ring 1 vertically, and first six edge groove 11 is arranged along the axis point of outer ring 1 circularly, and first six edge groove 11 is provided, which can reduce the weight of outer ring 1 on one hand, and can increase the pressure resistance of outer ring 1 to a certain extent on the other hand, and the outer wall of first buffer ring 4 and aramid fiber ring 5 is fixedly connected with the outer wall of connecting plate 3.
[0030] The outer wall of aramid fiber ring 5 side away from first buffer ring 4 is fixedly connected with second buffer ring 6, and the outer wall of second buffer ring 6 is fixedly connected with inner ring 7.

[0032] The inner wall of the inner ring 7 is provided with a second hexagonal groove 71, and the outer wall of the side of the inner ring 7 away from the second buffer ring 6 is fixedly connected with an inner sealing lip 8. The second hexagonal groove 71 is similar to the first hexagonal groove 11 of the outer ring 1, which can optimize the pressure resistance of the inner ring 7 while reducing the weight.
[0033] The second hexagonal groove 71 is arranged in a circular array along the axial center point of the inner ring 7, and the inner sealing lip 8 is vertically arranged along the outer wall of the inner ring 7.
