Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a bearing with a sealing structure. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] Some bearings are often immersed in water. Although this type of bearing does not rotate quickly, its sealing structure is relatively simple. Often only a sealing gasket is set at the installation location, resulting in poor sealing. Liquid will still flow between the inner ring and the outer ring of the bearing, easily causing the bearing balls to rust. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a bearing with a sealing structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A bearing with a sealing structure comprises a bearing body, the bearing body is composed of a bearing inner ring and a bearing outer ring, a plurality of bearing balls are evenly arranged between the bearing inner ring and the bearing outer ring, and sealing cover plates are symmetrically installed on the side walls of both sides of the bearing outer ring;

[0007] A plurality of mounting holes are evenly arranged on the side edge of one surface of the sealing cover plate, and fixing components are installed on the mounting holes. A limiting protrusion is arranged on the other side edge of the surface of one side of the sealing cover plate away from the mounting holes, and a groove is arranged on the outer side of the limiting protrusion.

[0008] In addition, a preferred structure is that a sealing gasket is attached to the surface of the sealing cover plate provided with the limiting protrusions and the grooves, and a surface of one side of the sealing cover plate provided with the sealing gasket contacts the inner ring of the bearing.

[0009] In addition, a preferred structure is that first protrusions are symmetrically arranged on the side walls of both sides of the bearing inner ring, and second protrusions are arranged on the inner side of the first protrusions, and the first protrusions can be inserted into the grooves.

[0010] In addition, a preferred structure is that a circular arc groove is formed on the second protrusion, and the limiting protrusion can be buckled into the circular arc groove.

[0011] In addition, a preferred structure is that a plurality of screw holes are evenly opened on the side walls of both sides of the bearing outer ring, and the fixing components can be screwed into the screw holes, and the screw holes are aligned with the centers of the mounting holes.

[0012] The beneficial effects of the utility model are as follows: by arranging the first protrusion and the second protrusion on the inner ring of the bearing, and with the cooperation of the groove and the limiting protrusion, the sealing gasket can be squeezed into an irregular shape, thereby making its sealing performance better, and when the bearing body is located in water, the liquid will not penetrate into the interior of the bearing body, and the sealing cover plates on both sides are also arranged to be detachable.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4 A bearing with a sealing structure includes a bearing body 001, which is composed of a bearing inner ring 4 and a bearing outer ring 3. A plurality of bearing balls 5 are evenly arranged between the bearing inner ring 4 and the bearing outer ring 3. Sealing cover plates 1 are symmetrically installed on the side walls of both sides of the bearing outer ring 3. A plurality of mounting holes 11 are evenly opened on the side edge of one surface of the sealing cover plate 1. A fixing component 2 is installed at the mounting hole 11. A limiting protrusion 13 is arranged on the side edge of the other side of the surface of one side of the sealing cover plate 1 away from the mounting hole 11. A groove 12 is arranged on the outer side of the limiting protrusion 13. The sealing cover plate 1 can effectively prevent the infiltration of liquid, thereby improving its sealing performance.

[0020] In addition, a sealing gasket 6 is attached to the surface of the sealing cover plate 1 where the limiting protrusions 13 and the grooves 12 are provided. The surface of one side of the sealing cover plate 1 where the sealing gasket 6 is provided is in contact with the bearing inner ring 4. The sealing gasket 6 is used to increase the sealing performance of the connection.

[0021] Moreover, first protrusions 41 are symmetrically arranged on the side walls of both sides of the bearing inner ring 4, and second protrusions 42 are arranged on the inner side of the first protrusions 41. The first protrusions 41 can be inserted into the grooves 12. The first protrusions 41 inserted into the grooves 12 can improve the sealing performance.

[0022] At the same time, a circular arc groove 421 is formed on the second protrusion 42, and the limiting protrusion 13 can be buckled into the circular arc groove 421. The limiting protrusion 13 is buckled into the circular arc groove 421 to improve the sealing performance.

[0023] In addition, multiple screw holes 31 are evenly opened on the side walls of both sides of the bearing outer ring 3. The fixing component 2 can be screwed into the screw hole 31. The screw hole 31 is aligned with the center of the mounting hole 11. The mounting hole 11 facilitates the fixing component 2 to be installed into the screw hole 31, thereby installing the sealing cover plate 1 on the bearing outer ring 3, and taking sealing measures at the connection.

[0024] In this embodiment, when installing the sealing cover plates 1 on both sides, align the mounting holes 11 with the screw holes 31, then screw each fixing component 2 into the screw holes 31, and take sealing measures at this connection, such as adding sealing gaskets, etc. When the bearing is running, the first protrusion 41 of the bearing inner ring 4 can be inserted into the groove 12, and the arc groove 421 of the second protrusion 42 cooperates with the limiting protrusion 13, so that the sealing gasket 6 is squeezed, making it difficult for liquid to penetrate.

[0025] In the utility model, by setting the first protrusion 41 and the second protrusion 42 on the bearing inner ring 4, and with the cooperation of the groove 12 and the limiting protrusion 13, the sealing gasket 6 can be squeezed into an irregular shape, so that its sealing performance is better. When the bearing body 001 is located in water, the liquid will not penetrate into the interior of the bearing body 001, and the sealing cover plates 1 on both sides are also set to be detachable.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
