The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a bearing seal ring, includes annular body, the ring body inner wall is provided with annular first seal lip, first seal lip surface is provided with the second seal lip, follows the stiff end to the free end direction of second seal lip, the second seal lip inside wall arrives the distance of annular body axis reduces gradually, the thickness of second seal lip increases gradually.
Preferably, the inner wall of the annular body is provided with a groove matched with the second sealing lip.
Preferably, the cross section of the second sealing lip is in a trapezoidal structure or a triangular structure.
Preferably, the distance from the free end of the inner side wall of the second sealing lip to the axis of the annular body is smaller than the distance from the end of the first sealing lip to the axis of the annular body.
Preferably, the outer surface of the first sealing lip is provided with a lug, and the lug is positioned at the end part of the first sealing lip.
Preferably, the end part of the annular body is provided with a second protective lug bent outwards.
The utility model has the advantages that: the utility model provides a bearing seal ring, includes annular body, the ring body inner wall is provided with annular first seal lip, first seal lip surface is provided with the second seal lip, follows the stiff end to the free end direction of second seal lip, the second seal lip inside wall arrives the distance of annular body axis reduces gradually, the thickness of second seal lip increases gradually. The inner side wall of the second sealing lip is of a wedge-shaped structure, one end of the free end of the second sealing lip is in close contact with the bearing inner ring under the extrusion action of the bearing inner ring, and the other end of the free end of the second sealing lip is in close contact with the inner wall of the annular body, so that the sealing performance is realized. The utility model discloses a first seal lip and second seal lip improve the sealing performance of sealing washer, avoid impurity to get into the bearing endosome, are favorable to improving bearing utility life.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the bearing seal ring of this embodiment, including annular body 1, the 1 inner wall of ring body is provided with annular first seal lip 2, 2 surfaces of first seal lip are provided with second seal lip 3, the cross section of second seal lip 3 is trapezium structure or triangle-shaped structure, follows the stiff end to the free end direction of second seal lip 3, 3 inside walls of second seal lip arrive the distance of 1 axis of annular body reduces gradually, the thickness of second seal lip 3 increases gradually, and annular body 1, first seal lip 2 and second seal lip 3 are coaxial, and all have the rubber material to make, and 3 inside walls of second seal lip (be the lateral wall that is close to second seal lip axis one side promptly) are the wedge structure. Because the distance from the inner side wall of the second seal lip 3 to the axis of the annular body 1 is gradually reduced, after assembly, the free end of the second seal lip 3 inclines towards the inner wall of the annular body 1 under the extrusion action of the bearing inner ring, one end of the free end of the second seal lip 3 is tightly contacted with the bearing inner ring, and the other end of the free end of the second seal lip 3 is tightly contacted with the inner wall of the annular body 1, so that the sealing action is realized; the utility model discloses a first seal lip 2 and second seal lip 3 realize sealed effect, improve the sealing performance of sealing washer, avoid impurity such as dust, water to get into inside the bearing. In addition, 3 inside walls of second seal lip are wedge structures, and the distance is a little bit between bearing inner race and the outer lane, the utility model discloses sealing performance also can be realized to the sealing washer.
The inner wall of the annular body 1 is provided with a groove 11 matched with the second sealing lip 3, one end of the second sealing lip 3 can be embedded into the groove 11, and the sealing performance is improved.
3 inside wall free ends of second seal lip reach the distance of 1 axis of annular body is less than 2 tip of first seal lip are arrived the distance of 1 axis of annular body is favorable to 3 one end of second seal lip and bearing inner race in close contact with, and simultaneously under second seal lip 3 and bearing inner race extrusion, the other end of second seal lip 3 can with the inside in close contact with of annular body 1, improves the sealing performance of second seal lip 3.
2 surfaces of first seal lip are provided with and protect ear 4, protect ear 4 to be located 2 tip of first seal lip, protect the ear can with the perpendicular setting of first seal lip surface is favorable to increasing the contact of 2 tip of first seal lip and race ring, reinforcing sealing performance.
The end part of the annular body 1 is provided with a second protection lug 5 which is bent outwards, so that the contact between the second protection lug 5 and the inner wall of the bearing outer ring is enhanced, and the sealing performance of the sealing ring is improved.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
