Description
Technical field
The utility model is related to a kind of automobile hub bearing sealing ring tightness energy testing machine.
Background technology
Automobile hub bearing work under bad environment, the both sides of hub bearing employ special sealing ring carry out it is close
Envelope, to avoid the foreign matters such as dust, water, mud from entering Bearing inner, and then pollutes and corrosion hub bearing internal raceways and rolling
Body, so as to ensure the service behaviour and service life of bearing.Therefore, the quality of sealing ring tightness energy seems outstanding to hub bearing
For important.
The structure of automobile hub bearing：Automobile hub bearing is constituted by inner ring, outer ring and two row rolling elements, and two row are rolled
Body ensure that the relative position relation of inner ring and outer ring by this two row rolling element, i.e., in normal shape between inner ring and outer ring
The axis of inner ring and the axis of outer ring are consistent during state, and inner ring and outer ring can relatively rotate around axis.One complete
Whole automobile hub bearing, there is two sealing rings, is separately mounted to the outside of two row rolling elements, and its effect is to prevent dust, water, mud

Under part, tested using timing operation, i.e., test run time is up preset value when, be automatically stopped, manually disassemble and tested
Bearing, the vestige that observation Bearing inner is whether there is into slime water (because practical bearing both sides are sealing state, are only destroyed and is somebody's turn to do
Bearing can detect the state of sealing ring, otherwise be difficult to judge whether sealing ring fails).If Bearing inner does not have slime water
Vestige, then it represents that sealing ring does not fail also, but it is not aware that how long the sealing ring can also work；If Bearing inner has mud
The vestige of pulp-water, then it represents that sealing ring has failed, still cannot know specific effectively operating time.Therefore, this experiment
