Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-7：A kind of radial direction
The elastic floating ring oil sealing of bearing, including cartridge housing 10 and bearing tile 11, bearing tile 11 is fixed on bearing by spacer pin 16
The inner wall of shell 10, can be there are gap between axis 21 when the bearing tile 11 is installed on axis 21, which becomes oil pocket
22, lubricating oil is entered in oil pocket 22, and when 21 high speed rotation of axis, one layer of oil can be formed between bearing tile 11 and axis 21
Film reduces abrasion between the two, wherein, the both sides of the bearing tile 11 are both provided with retainer 12, the retainer 12
Outer wall be provided with limiting stop pin I 17, and pass through and limit the inner wall that stop pin I 17 is fixed on cartridge housing 10, prevent retainer
