Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of dust-proof anti-extrusion roller rotating shaft, including
Bearing inner race 1, bearing outer ring 4, roller holder 5, occlusal crib circle 7, outer protective housing 8, damping supporting 12 and fluid are squeezed
Pressure chamber 13, the inner surface of bearing inner race 1 is inlaid with and lubricating oil pouring orifice 3 is inlaid with the middle of antiskid groove 2, and bearing inner race 1, anti-skidding
