Abstract
The present invention relates to a kind of bearing seal structures, can specifically bear the bearing seal structure of tilting moment, belong to bearing seal structure technical field.It includes bearing inner race, bearing outer ring, ball and dustproof cover, and dustproof cover circle end face is equipped with upper sealing ring, is equipped with outer collar dustproof groove on the inside of bearing outer ring, the upper sealing ring of dustproof cover outer circle is installed on the outer collar dustproof groove of bearing outer ring；Dustproof cover inner circle end face is equipped with the lower sealing ring extended vertically downward, the corner of bearing inner race towards the lower sealing ring of dustproof cover is equipped with the dust-proof inclined-plane of inner ring, the lower sealing ring of dustproof cover is pressed on the dust-proof inclined-plane of inner ring, realizes the compression sealing of dustproof cover inner side end and bearing inner race.The invention has the advantages of simple structure, compactness and reasonable structure, and bearing can be avoided to be happened because tilting moment generates seal clearance, enhance bearing seal performance, prevents grease from leaking and foreign matter intrusion, improves bearing life.
Description
Technical field
The present invention relates to a kind of bearing seal structures, can specifically bear the bearing seal structure of tilting moment,
Belong to bearing seal structure technical field.
Background technology
Leakage fat phenomenon easily occurs when in use for full ball bearing, and leakage fat phenomenon leads to bearing failure, reduces making for bearing
Use the service life.In the prior art, dustproof cover is set to be sealed generally between bearing internal external circle.In order to fix dustproof cover, need
The setting sealing card slot on bearing internal external circle, general sealing card slot is v-shaped structure or L-shaped structure.Existing sealing structure, in axis
Under the conditions of bearing certain tilting moment, as angle bias radially occurs for bearing internal external circle, sealing structure will not be with bearing
The mode of load and change, easily generate seal clearance, bearing seal performance caused to reduce, again generate leakage fat phenomenon.
Invention content
It is an object of the present invention to overcome the above deficiencies, so as to provide a kind of bearing seal structure, can avoid axis
It holds because tilting moment generates happening for seal clearance, enhances bearing seal performance, improve bearing life.
According to technical solution provided by the invention, a kind of bearing seal structure include bearing inner race, bearing outer ring, ball and
Dustproof cover, bearing outer ring is interior to be equipped with bearing inner race, and ball is equipped between bearing outer ring and bearing inner race, it is characterized in that：Ball
The left and right sides is equipped with dustproof cover, and dustproof cover circle end face is equipped with upper sealing ring, and outer collar dustproof groove is equipped on the inside of bearing outer ring, dust-proof
The upper sealing ring of lid outer circle is installed on the outer collar dustproof groove of bearing outer ring；Dustproof cover inner circle end face equipped under extending vertically downward
Sealing ring, the corner of bearing inner race towards the lower sealing ring of dustproof cover are equipped with the dust-proof inclined-plane of inner ring, the lower sealing ring of dustproof cover
It is pressed on the dust-proof inclined-plane of inner ring, realizes the compression sealing of dustproof cover inner side end and bearing inner race.
Further, upper sealing ring and outer collar dustproof groove are L-shaped structure.
Further, dustproof cover inner circle end face is equipped with to the horizontal-extending side seal ring in ball direction.
Further, side seal ring cross section is trapezoidal.
Compared with the prior art the present invention has the following advantages：
The invention has the advantages of simple structure, compactness and reasonable structure, and bearing can be avoided to increase because tilting moment generates happening for seal clearance
Strong bearing seal performance, prevent grease leak and foreign matter intrusion, improve bearing life.
Description of the drawings
Fig. 1 is front view of the present invention.
Fig. 2 is to amplify at A in Fig. 1.
Reference sign：In the outer collar dustproof groove of 1- bearing inner races, 2- bearing outer rings, 3- balls, 4- dustproof covers, 5-, 6-
Enclose dust-proof inclined-plane, 7- upper sealing rings, 8- lower sealing rings, 9- side seal rings.
Specific embodiment
The present invention will be further described with reference to the embodiment in attached drawing below：
As shown in Figure 1 and 2, the invention mainly comprises bearing inner race 1, bearing outer ring 2, ball 3 and dustproof cover 4, in bearing outer ring 2
Equipped with bearing inner race 1, ball 3 is equipped between bearing outer ring 2 and bearing inner race 1.
The left and right sides of ball 3 is equipped with dustproof cover 4, and 4 circle end face of dustproof cover is equipped with the upper sealing ring 7 of L-shaped structure, bearing
2 inside of outer ring is equipped with the outer collar dustproof groove 5 of L-shaped structure, and the upper sealing ring 7 of 4 outer circle of dustproof cover is installed on the outer ring of bearing outer ring 2
Dustproof groove 5.
4 inner circle end face of dustproof cover is equipped with the lower sealing ring 8 that extends vertically downward and close to the horizontal-extending side in 3 direction of ball
Seal ring 9, the corner of bearing inner race 1 towards the lower sealing ring 8 of dustproof cover 4 are equipped with the dust-proof inclined-plane 6 of inner ring.It is close under dustproof cover 4
Seal ring 8 is pressed on the dust-proof inclined-plane 6 of inner ring, realizes the compression sealing of dustproof cover inner side end and bearing inner race.
9 cross section of side seal ring is trapezoidal.
The lower sealing ring sealing cooperation on the dust-proof inclined-plane of inner ring and dustproof cover of middle (center) bearing inner ring of the present invention so that bearing is closing
Any angle in the range of reason can be generated and effectively be sealed, and enhancing bearing seal performance prevents that grease from leaking and foreign matter is invaded
Enter.
