Description

Technical Field

[0001] The utility model belongs to the technical field of bearing sealing covers, and more specifically relates to a single-layer convex-edge outer spherical bearing sealing cover. Background Art

[0002] The outer spherical bearing sealing cover is a key seal installed on the outside of the bearing. It is of great significance to ensure the stable operation and extend the service life of the bearing. It has the functions of dustproof, waterproof and anti-pollution. However, after the traditional sealing cover is installed on the bearing, the contact area between the inner edge of the sealing cover and the bearing is relatively small. After a period of use, oil leakage is prone to occur, which reduces the service life of the bearing. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a single-layer convex outer spherical bearing sealing cover, which aims to solve the problem that the contact surface between the inner edge of the existing sealing cover and the bearing is relatively small, and oil leakage is likely to occur after a period of use.

[0004] The utility model discloses a single-layer convex outer spherical bearing sealing cover, which is achieved by the following specific technical means:

[0005] A single-layer convex-edge outer spherical bearing sealing cover comprises a sealing cover body; a support ring is installed on the bottom surface of the sealing cover body, and a dustproof layer is fixedly provided on the top surface of the sealing cover body.

[0006] Furthermore, the sealing cover body is a closed annular structural ring, and the sealing cover body is installed on the outside of the outer spherical bearing, with the top surface of the sealing cover body facing outward.

[0007] Furthermore, a raised convex edge is provided on the inner edge of the top surface of the sealing cover body, and the top surface height of the convex edge is higher than the top surface height of the sealing cover body. After the sealing cover body is installed on the outer spherical bearing, the convex edge can be fitted to the inner wall of the inner ring of the outer spherical bearing, and the convex edge is higher than the height of the roller, thereby increasing the sealing area and preventing oil leakage.

[0008] Furthermore, the dustproof layer is arranged on the top surface of the convex edge. When the sealing cover body is installed on the outer spherical bearing, the top edge of the dustproof layer is in contact with the inner ring of the bearing.

[0009] Furthermore, an external card groove is provided on the bottom surface of the sealing cover body. The external card groove is an annular structure and is made by integrally molding with the sealing cover body through a mold. The internal clamping support ring of the external card groove can be used to selectively increase the sealing thickness of the sealing cover body, and the hardness of the sealing cover body can be increased through the support ring.

[0010] The utility model has at least the following beneficial effects:

[0011] The utility model is provided with a convex edge. After the sealing cover body is installed on the outer spherical bearing, the convex edge can be attached to the inner wall of the inner ring of the outer spherical bearing. The convex edge is higher than the height of the roller, and the sealing area is increased. Compared with the traditional sealing cover, it can better prevent the lubricating grease inside the bearing from leaking.

[0012] By providing a dustproof layer, the gap between the convex edge and the bearing can be further prevented from leaking grease, thereby achieving better water-removing, anti-fouling, dust-proof and oil-leaking prevention effects.

[0013] In addition, the support ring increases the hardness of the sealing cover body, thereby avoiding deformation during use due to the soft material of the sealing cover body itself, thereby ensuring the protection effect and service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0023] Example:

[0024] As attached Figure 1 To the attached Figure 4 As shown:

[0025] The utility model provides a single-layer convex outer spherical bearing sealing cover, comprising a sealing cover body 1; a support ring 2 is installed on the bottom surface of the sealing cover body 1, and a dustproof layer 3 is fixedly provided on the top surface of the sealing cover body 1.

[0026] As attached Figure 2As shown, the sealing cover body 1 is a closed annular structure ring. The sealing cover body 1 is installed on the outside of the outer spherical bearing, and the top surface of the sealing cover body 1 faces outward. The sealing cover body 1 can protect the outer spherical bearing, play the role of waterproofing, anti-pollution, and anti-oil leakage, thereby improving the service life of the outer spherical bearing.

[0027] As attached Figure 4 As shown, the dustproof layer 3 is arranged on the top surface of the convex edge 101. When the sealing cover body 1 is installed on the outer spherical bearing, the top edge of the dustproof layer 3 is in contact with the inner ring of the bearing. By providing the dustproof layer 3, the gap between the convex edge 101 and the bearing can be further prevented from leaking grease, thereby achieving better water-repelling, anti-fouling, dust-proof and oil-leakage-proof effects.

[0028] As attached Figure 4 As shown, an external card groove 102 is provided on the bottom surface of the sealing cover body 1. The external card groove 102 is an annular structure and is made by integrally molding with the sealing cover body 1 through a mold. The internal part of the external card groove 102 is clamped with the support ring 2. The external card groove 102 can be used to selectively increase the sealing thickness of the sealing cover body 1, and at the same time, the hardness of the sealing cover body 1 can be increased through the support ring 2.

[0029] As attached Figure 4 As shown, a raised ridge 101 is provided on the inner edge of the top surface of the sealing cover body 1. The top surface height of the ridge 101 is higher than the top surface height of the sealing cover body 1. After the sealing cover body 1 is installed on the outer spherical bearing, the ridge 101 can be fitted to the inner wall of the inner ring of the outer spherical bearing. The ridge 101 is higher than the height of the roller, and at the same time, the sealing area is increased to better prevent oil leakage.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present invention, after the sealing cover body 1 is installed on the outer spherical bearing, the convex edge 101 can be fitted to the inner wall of the inner ring of the outer spherical bearing, and the top edge of the dustproof layer 3 is fitted to the inner ring of the bearing. By setting the dustproof layer 3, the gap where the convex edge 101 contacts the bearing can further prevent grease from leaking.
