Description

Technical Field

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

[0002] Spherical plain bearings are spherical sliding bearings, whose sliding contact surfaces are an inner spherical surface and an outer spherical surface. They can rotate and swing at any angle during movement. They are made by surface phosphating, blasting, inserting gaskets, spraying and other special processing methods. Spherical plain bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication, etc. Spherical plain bearings are widely used in engineering hydraulic cylinders, forging machines, engineering machinery, automation equipment, automobile shock absorbers, water conservancy machinery and other industries. Spherical plain bearings are spherical sliding bearings. The basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. Depending on its structure and type, it can withstand radial loads, axial loads, or combined loads of radial and axial forces acting simultaneously.

[0003] However, some sand and gravel impurities are easy to enter between the inner and outer rings of the spherical bearing. These impurities will accelerate the wear of the spherical bearing and affect the normal use of the spherical bearing.

[0004] Therefore, the utility model provides a bearing with dustproof function to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a bearing with a dustproof function, which solves the above-mentioned problems. By opening an annular groove on the outer ring of the joint bearing body and putting a rubber ring and a rubber cover in the annular groove, mud and water can be effectively prevented from entering. The through hole allows other transmission rods to be inserted and used in conjunction with the joint bearing body. The rubber ring and the rubber cover are both made of soft rubber. Since soft rubber has excellent elasticity, it can have a large deformation buffer to adapt to the spatial changes generated when the joint shaft body is used in conjunction with other components.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a bearing with dustproof function, including a joint bearing body, a protective component is arranged on the outside of the joint bearing body; the protective component includes an annular groove, the annular groove is opened inside the outer ring of the joint bearing body, a rubber ring is sleeved inside the annular groove, and a rubber cover is fixedly connected to one side of the rubber ring.

[0007] Furthermore, a through hole is formed at one end of the rubber cover.

[0008] By adopting the above technical solution, other components can be matched.

[0009] Furthermore, an auxiliary pull ring is fixedly connected to the outer wall of the rubber ring.

[0010] By adopting the technical solution, it is convenient to pull the rubber ring for sleeve connection.

[0011] Furthermore, the rubber cover and the rubber ring should be made of soft rubber.

[0012] By adopting the above technical solution, soft rubber is also called soft rubber and soft glue. It usually refers to vulcanized rubber with low sulfur content and good elasticity and softness. It can be used to make most rubber products such as tires, belts, hoses, rubber shoes, etc.

[0013] Furthermore, the auxiliary pull ring should be made of engineering plastics.

[0014] By adopting the above technical solution, the engineering plastic has high strength, corrosion resistance and high temperature resistance, and is lighter than metal of the same volume, effectively reducing the overall weight of the device.

[0015] Furthermore, a total of eight auxiliary pull rings are evenly fixed on the outer wall of the rubber ring.

[0016] By adopting the above technical solution, pulling force can be applied from all directions to provide leverage points.
