Description
Technical field
The present invention relates to a kind of bearing seal technical fields, and in particular to a kind of double-layer seal rings deep groove ball bearing.
Background technique
Deep groove ball bearing is most representative rolling bearing, such bearing friction coefficient is small, and limit speed is high, structure letter
Single, manufacturing cost is low, easily reaches the higher accuracy of manufacture, size range and form variation multiplicity, extensive as gearbox bearing
It is practical.
The sealing bearing of usually filling lubricating grease is that every face with a piece of sealing ring seals lubricating grease after loading lubricating grease.
National Specification loads the contact seal bearing of lubricating grease (i.e. sealing lip and inner ring seal groove are in close contact and have interference)
The leakage rouge rate of permission is 5%, the leakage rouge of non-contacting seal bearing (i.e. sealing lip and inner ring seal groove are contactless and have gap)
Rate is 10%.Actually by experiments have shown that, to be really achieved the above index has comparable difficulty.
And the sealing bearing requirements zero leakage for the filling lubricating grease that some occasions use, it is difficult using common sealing bearing
Accomplish zero leakage.Meanwhile in the case where the environment of certain special contaminations and the external world have certain pressure, extraneous dirt is easy to
Bearing inner is penetrated into through sealing ring, dirt can be such that bearing is quickly invalidated after penetrating into Bearing inner, and common single facer is also very
Difficulty blocks extraneous dirt and penetrates into Bearing inner.

The present invention provides a kind of double-layer seal rings deep groove ball bearing.
As shown in Figs. 1-2, a kind of double-layer seal rings deep groove ball bearing, including bearing outer ring 1, bearing inner race 2 and installation
Ball 3 between bearing outer ring 1 and bearing inner race 2 and the retainer 4 for fixing ball 3, the bearing outer ring 1 with it is described
It is additionally provided with the first sealing ring 10 and the second sealing ring 20 between bearing inner race 2, first sealing ring 10 and described second close
There are gaps between seal 20, so that bearing is during exercise, the first sealing ring 10 is not interfere with each other with the second sealing ring 20, in addition,
Double-layer seal coil structures have better seal effect.
The inner wall end of the bearing outer ring 1 offers the first seal groove 5 and the second seal groove 6, the bearing inner race 2
Outer wall end offers third seal groove 7 and the 4th seal groove 8, wherein an end face of second seal groove 6 is that guiding is oblique
Face.
The inner wall of first sealing ring 11 towards the bearing outer ring 1 is extended with the first sealing lip 11, and described first is close
Envelope lip 11 is bonded with 5 bottom surface of the first seal groove, so that the first sealing ring 10 is fixed on bearing outer ring 1, is also functioned to simultaneously
The phenomenon that preventing the first sealing ring 1 from falling.
Further, the outer wall of first sealing ring 11 towards the bearing inner race 2 is extended with the second sealing lip 12, institute
It states the second sealing lip 12 and forms clearance fit with 7 bottom surface of third seal groove, the lubricant grease in bearing can be prevented in this way
It leaks out, in addition, the first sealing ring 10 is formed with arc-shaped Oil Guide face 13 to center of circle direction, Oil Guide face 13 is made with Oil Guide
With the lubricant grease for being thrown on bearing sealed ring in bearing movable can tilt in water conservancy diversion to bearing, so that ball 3 begins
Good lubricant effect eventually, while also improving the utilization rate of lubricating oil.
The outer wall end of second sealing ring 20 towards the bearing inner race 2 is extended with third sealing lip 21, and described
Three sealing lips 21 are bonded with 8 bottom surface of the 4th seal groove, so that the second sealing ring 10 is fixed on bearing inner race 2, while
Play the phenomenon that preventing the second sealing ring 2 from falling.
Second sealing ring 20 is extended with the 4th sealing lip 22, the 4th sealing lip 22 and institute towards 3 direction of ball
The guiding surface for stating the second seal groove 6 forms clearance fit, and setting is so that bearing during exercise, reduces by the 4th sealing lip 22 in this way
With the friction between bearing outer ring 1, in addition, the guiding surface of the 4th sealing lip 22 and the second seal groove 6 formed clearance fit energy
It is enough further to prevent the lubricant grease in bearing from revealing.
Further, the second sealing ring 20 is extended with the 5th sealing lip 23 towards 1 inner wall end of bearing outer ring, and the described 5th
The bottom surface of sealing lip 23 and second seal groove 6 forms clearance fit, can effectively prevent so extraneous pollutant into
Enter in bearing, in addition, can also pass through the 4th sealing lip 22 even if there is lubricant grease to leak out by the second sealing lip 12 accidentally
Further limitation oil leakage.
In addition, the first sealing ring 10 and the second sealing ring 20 are by rubber bodies and are coated on the intracorporal skeleton of rubber and constitute,
Setting can reinforce the intensity of sealing ring, keep shape and tension in this way.
Finally it should be noted that: the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;To the greatest extent
Pipe implements that invention is explained in detail referring to preceding narration, it will be understood by those of skill in the art that it still can be with
