Description

Technical Field

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

[0002] A bearing is a mechanical element that limits relative motion to a desired range of motion and reduces friction between moving parts. The design of the bearing can provide free linear motion of the moving parts or free rotation around a fixed axis, or prevent motion by controlling the vector of the normal force acting on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Horizontal bearings are characterized by being parallel to the axis and can withstand horizontal loads as well as vertical loads, but are limited in size and are widely used in machinery with larger loads, such as hydroelectric generators, compressors, and gearboxes. Due to different working environments, there may be a lot of dust that hinders the movement of the bearing, which requires a horizontal bearing sealing structure.

[0003] Today's horizontal bearing sealing structure can basically meet people's use needs, but there are still some problems. The specific problems are as follows:

[0004] 1. The sealing structure of horizontal bearings is difficult to isolate external dust and internal lubricating oil at the same time. Most of the horizontal bearings nowadays cannot be completely sealed, causing dust to enter and affect the rotation of the bearings and internal lubricating oil to leak out. In addition, due to the different working environments of horizontal bearings during use, the requirements for sealing conditions are also different, making it difficult to adjust during use.

[0005] 2. The sealing structure of horizontal bearings is difficult to adapt to various working environments. When using horizontal bearings, due to the high temperature and high pressure in the working environment, the horizontal bearings need to be able to adapt to various harsh conditions to improve their own stability. Utility Model Content

[0006] The utility model aims to provide a horizontal bearing sealing structure to solve the defects of the existing horizontal bearings that are difficult to seal and have poor bearing capacity.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a horizontal bearing sealing structure, comprising an inner wheel;

[0008] A dustproof structure is arranged on the outer side of the inner wheel, and the dustproof structure comprises a spring ring, a dustproof cover, a dustproof lip, and a frame, and the spring ring is installed on the outer side of the inner wheel;

[0010] The outer side of the dustproof structure is provided with a shaft ring structure, the inner side of the inner wheel is provided with an electroplating coating, and one end of the dustproof structure is provided with a cabin body.

[0011] When in use, first the outer wheel and inner wheel of the horizontal bearing are fixed in contact with the corresponding working surfaces respectively, and the inner rolling body rolls in the rolling groove, so that the inner and outer diameters of the horizontal bearing and its working surface can rotate freely around the fixed axis. During operation, the dust cover can prevent external dust and other debris from entering the horizontal bearing and affecting its operation. The dustproof lip ensures that the lubricating oil inside the bearing will not leak outward. The ceramic layer, insulating layer, carbide layer and electroplating coating arranged on the inner and outer diameters make the bearing have excellent high temperature resistance, wear resistance and corrosion resistance, so that the horizontal bearing can maintain a good working condition even in extreme environments, thereby achieving the sealing and rolling of the horizontal bearing.

[0012] Furthermore, the shaft ring structure includes a carbide layer, an insulating layer, a ceramic layer, and an outer wheel. The outer wheel is installed on the outside of the dustproof structure, a ceramic layer is provided on the outside of the outer wheel, an insulating layer is provided on the outside of the ceramic layer, and a carbide layer is provided on the outside of the insulating layer, to ensure that the outer wheel of the horizontal bearing has excellent high temperature resistance, wear resistance and corrosion resistance.

[0013] Furthermore, the spring ring is elastic, and the spring ring and the outer wheel form a snap-fit ​​structure, so that the dust cover of the horizontal bearing can be disassembled at will according to usage requirements.

[0014] Furthermore, the dust lip is elastic, and the dust lip and the inner wheel form a closed structure, thereby ensuring that the lubricating oil in the horizontal bearing compartment will not leak outward.

[0015] Furthermore, a rolling structure is arranged on the outer side of the inner wheel, and the rolling structure includes a retaining frame, a rolling body, and a rolling groove. The rolling groove is arranged on the inner side of the shaft ring structure, and the rolling groove is arranged on the outer side of the inner wheel, thereby ensuring smooth rolling of the rolling body and increasing the bearing capacity of the bearing.

[0016] Furthermore, the inner diameter of the rolling groove is larger than the outer diameter of the rolling body, and the rolling body and the rolling groove form a sliding structure, thereby ensuring that the rolling body rolls on the same path.

[0017] Furthermore, a retaining frame is arranged on the outer side of the rolling body, and the rolling body is distributed in a ring shape, so as to stabilize the relative position of the rolling body and ensure smooth rolling.

[0018] The horizontal bearing sealing structure provided by the utility model has the following advantages: a dustproof lip is arranged between the outer wheel and the inner wheel of the horizontal bearing, one end of the dustproof lip is fixed on the outer wheel, and the other end is in contact with the inner wheel; the dustproof lip is elastic and uses the internal skeleton to maintain a stable shape, thereby forming a closed cabin, ensuring that the lubricating oil inside the bearing will not leak outward; at the same time, a card slot is arranged on the inner side of the inner and outer wheels, and a dust cover can be placed in the card slot and fixed with an elastic spring ring, thereby preventing external dust and other debris from entering the interior of the horizontal bearing to affect the work, ensuring smooth rolling of the rolling body, and the dustproof cover can be disassembled according to use requirements, thereby achieving the purpose of facilitating complete sealing of the horizontal bearing sealing structure.

[0019] A ceramic layer, an insulating layer and a hard alloy layer are sequentially arranged on the outer wheel of the horizontal bearing. The ceramic layer is made of ceramic, the insulating layer is made of rubber, and the hard alloy layer can be made of tungsten, cobalt, nickel and other metals. An electroplating coating is installed on the inner wheel. The electroplating coating can be made of nickel, chromium, cadmium and other metals. The bearing has excellent high temperature resistance, wear resistance and corrosion resistance, and the horizontal bearing can maintain a good working condition even in extreme environments. In this way, the sealing structure of the horizontal bearing can adapt to complex and changeable working conditions and improve the reliability and stability of the bearing.
