Fig. 3 is an enlarged view of a portion a in fig. 1.
In the figure: 1. the sealing structure comprises a box body, 2, a rotating shaft, 3, a cylindrical roller bearing, 4, a shaft hole, 5, an oil seal, 6, a wave spring, 7, a sealing cover, 8, an annular sealing plate, 9, an inner annular boss, 10, an outer annular boss, 11 and an annular sealing groove.
Detailed Description
The invention will be further described with reference to the following detailed description and accompanying drawings.
Example (b): as shown in fig. 1 to 3, a sealing mechanism for a cylindrical roller bearing includes a housing 1 and a rotating shaft 2. The box body 1 is provided with a shaft hole 4. The rotating shaft 2 passes through the shaft hole 4. A cylindrical roller bearing 3 is arranged between the rotating shaft 2 and the box body. The cylindrical roller bearing 3 is arranged on the rotating shaft 2 at one side close to the through hole 4. An oil seal 5 is arranged between the rotating shaft 2 and the through hole.
One end of the cylindrical roller bearing 3 far away from the shaft hole 4 is covered with a sealing cover 7. The seal cap 7 includes an annular seal plate 8. The annular sealing plate 8 is circular. The annular seal plate 8 is attached to the side surface of the bearing outer ring of the cylindrical roller bearing 3. The inner edge and the outer edge of the annular sealing plate are respectively provided with an inner annular boss 9 and an outer annular boss 10 which are suspended in the direction perpendicular to the annular sealing plate 8. The inner annular boss 9 is sleeved on the bearing inner ring of the cylindrical roller bearing 3. The inner annular boss 9 is in interference fit with the bearing inner ring of the cylindrical roller bearing 3. The side of the bearing outer ring of the cylindrical roller bearing 3 facing the sealing cover 7 is provided with an annular sealing groove 11. An outer annular boss 10 is embedded in an annular seal groove 11. The front end of the outer annular boss 10 abuts against the bottom of the annular seal groove 11.
