High rotating speed, big jerk value occasion to solve the technical issues of similar product is not high to the tracing ability of axis in the prior art, are changed
The technique effect of kind parts leakproofness.
To achieve these goals, the utility model uses following technical solution.
The utility model discloses a kind of axle sealing ring for adapting to the high big jerk value of rotating speed, including：Oil drive back thread is set
On the inside of at the lip of axle sealing ring；The support portion of Z-shaped shape structure, is connected with the lip of axle sealing ring；Metallic framework,
Supported portion coats completely；And radial load counterbalance spring, it is arranged on outside at the lip of axle sealing ring.
Further, metallic framework is in the one end of support portion away from lip.
Further, support portion is made of elastic material.
Further, pressure sensor is provided on the outside of support portion, the pressure sensor is connected with external indicator light.
Further, oil drive back thread is uniformly distributed in inside at lip.
The beneficial effects of the utility model are：Prior art problem is overcome, creatively proposes that the improved height that adapts to turns
The axle sealing ring of fast big jerk value；The axle sealing ring utilizes the high resiliency feature of support portion Z-shaped shape structure, greatly improves
Tracing ability of the lip to axis, and pass through interference fit and carry out runout compensation, on the one hand reach seal reliable and stable use will
It asks, another aspect radial load is smaller than traditional design by big interference volume compensation jerk value, makes life of product longer.
