The utility model is further arranged to the second sealing lip tensioner and is arranged in inserting groove, second sealing lip
It is extended with inclined plate to outer ring inner peripheral surface direction, combination forms accommodation groove between the inclined plate and the second metallic framework.
The beneficial effect being arranged in this way is: using the above scheme, the second sealing lip is extended with tiltedly to outer ring inner peripheral surface direction
Plate combines to form accommodation groove between inclined plate and the second metallic framework, and the dust outside bearing operation and sundries will enter bearing
When internal, dust and sundries can be stopped by the inclined plate of the second sealing lip, then be downwardly into accommodation groove along inclined plate, in this way
The dust of Bearing outer and impurity are just not easy to enter Bearing inner through the second sealing lip, the leakproofness of the sealing structure compared with
It is good, and structure is simple, is conducive to realize, and when bearing shuts down, the sundries in accommodation groove can be cleaned out with dust
Come, is convenient to clean and cleans.
The utility model is further arranged to combine to form closed accommodating cavity between first sealing ring and inclined plate.
The beneficial effect being arranged in this way is: using the above scheme, oil liquid or other filling liquids, shape is filled in closed accommodating cavity
At a kind of seal protection, the leakproofness of bearing entirety is further improved.
Detailed description of the invention
