[0024] Please see Figure 1 and Figure 2 A bearing housing cover with good dustproof effect;

[0025] Includes: a cover body 1 and a sealing gasket assembly 3. A mating ring 14 is installed on the outer side of the fixed end of the cover body 1. The sealing gasket assembly 3 is installed on the back of the mating ring 14. The sealing gasket assembly 3 is used to increase the sealing performance of the cover body 1. The sealing gasket assembly 3 includes a sealing gasket body 4, a metal ring 5 and an anti-corrosion layer 6. The sealing gasket body 4 is fixed to the back of the mating ring 14. The metal ring 5 is installed on the back of the sealing gasket body 4. The anti-corrosion layer 6 is coated on the outer side of the sealing gasket body 4. Multiple fasteners 2 are installed on the outer side of the mating ring 14.

[0026] The cover body 1 is used to install on one side of the bearing seat, and seals one side of the bearing seat. When the cover body 1 is installed, the butt joint ring 14 is butted with the connecting part of the bearing seat, and then the fixing part 2 is connected with the threaded hole on the bearing seat through the threaded rotation of the bolt, so that the cover body 1 is fixed on one side of the bearing seat. In order to improve the sealing performance between the cover body 1 and the bearing seat, and avoid dust entering the inside of the bearing seat through the connecting part, the sealing gasket assembly 3 is installed at the butt joint part of the butt joint ring 14 and the bearing seat. The sealing gasket body 4 in the sealing gasket assembly 3 improves the sealing performance of the butt joint part. In order to make the sealing gasket body 4 have better use effect, the metal ring 5 installed in the sealing gasket body 4 improves the mechanical properties thereof. The anti-corrosion layer 6 coated on the outer side of the sealing gasket body 4 avoids the corrosion of the sealing gasket body 4 caused by the influence of the external environment, so as to affect the use effect. Through the installation of the sealing gasket assembly 3, the sealing performance of the bearing seat cover is better, and the dustproof effect is better.

[0027] Please refer to Figure 1 , Figure 3 and Figure 4 , a bearing seat cover with good dustproof effect;

[0028] The straight-angle mounting plate 7 and the rolling shaft 13 are installed on the top and both sides of the butt joint ring 14. The through groove 9 is formed in the top of the straight-angle mounting plate 7. The connecting spring 8 is symmetrically installed on the top of the straight-angle mounting plate 7, and is located outside the through groove 9. The connecting plate 10 is installed on the top end of the connecting spring 8. The mounting block 11 is installed on the bottom of the connecting plate 10, and penetrates the inner wall of the top of the straight-angle mounting plate 7 through the through groove 9. The mounting groove 12 is formed in the bottom of the mounting block 11. The rolling shaft 13 is rotatably installed in the mounting groove 12, and protrudes from the bottom of the mounting block 11.

[0029] The through groove 9 is formed in the straight-angle mounting plate 7, and provides a position for the installation of the connecting spring 8. The through groove 9 provides a space for the mounting block 11 to penetrate the straight-angle mounting plate 7. The connecting spring 8 provides a position for the installation of the connecting plate 10. The mounting block 11 can be installed and used through the connecting plate 10. The bottom of the mounting block 11 provides a space for the rotational installation of the rolling shaft 13 through the mounting groove 12. Since the top of the straight-angle mounting plate 7 extends to the outside of the bearing seat, when the bearing seat cover is installed, the rolling shaft 13 is driven to move upward by the pressure, so that the connecting plate 10 stretches the connecting spring 8 upward. The connecting spring 8 generates a downward force to make the rolling shaft 13 generate a downward pressure on the outside of the bearing seat. The rolling shafts 13 on both sides generate pressure at the same time, so that the cover body 1 is pre-positioned at one end of the bearing seat. When the cover body 1 is fixed by the bolt, it will not move and fall off, which facilitates the installation of the cover body 1 by the bolt. Since the rolling shaft 13 can roll, it is also convenient for the staff to rotate the positioned cover body 1, and adjust the position of the fixing part 2, so that the cover body 1 is more convenient to install.

[0030] Working principle, first through the sealing gasket assembly 3 is installed in the bearing seat in one end of the cover 1, under the seal of sealing gasket assembly 3, the sealing between the cover 1 and the bearing seat is better, avoid dust through the interface into the inside of the bearing seat, at the same time, the cover 1 will be installed in the first through the connecting spring 8 on the pressure of the mounting block 11, the rolling shaft 13 is pressed on the outside of the bearing seat, so that the cover 1 can be pre positioned in one end of the bearing seat, then adjust to the corresponding position by rotating, fixed by bolt.

[0031] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments but can be implemented in other embodiments without departing from the scope of the present application. The scope of the present application is defined by the appended claims rather than by the foregoing description, and therefore all changes and modifications that come within the meaning and range of equivalents of the claims are to be embraced by the application. Any reference signs in the claims should not be construed as limiting the claims.
