The main characteristics of oil seal
The outer oil seal under the excellent china oil seal design is used to ensure the static sealing of the cavity – the outer edge of the rubber and the inner metal frame; the outer edge of the exposed metal frame needs to be polished and coated with anti-corrosion coating.
The sealing lips equipped with a spring to ensure the dynamic and static sealing reliability of the shaft. After long -term development research, the sealing lip structure of the oil seal is improved to excellent performance, which in turn improves the sealing reliability within a wider load range.
Adding dust -proof lips, or multiple dust -proof lips used under special circumstances can prevent external pollutants and dust invasion.
What is a box oil seal? Also known as maze oil seal
This kind of oil seal has a relatively special structural form, which is different from ordinary oil seals. Generally consisting of the outer ring and the inner ring. The outer ring is a bit like our ordinary skeleton oil seal, but it is generally specially designed, such as positioning, dustproof, oil storage and other structures. The special place is the internal slip ring. When working, the slide rings are rotated together, and the sealing lips are only coordinated and friction with the same slide ring. The characteristic of box oil seal is strong anti -pollution capacity and can be used for large pollution occasions, such as heavy car bridges, concrete machinery, agricultural machinery, etc.
The life of the box oil seal is generally longer than that of ordinary oil seals, so the replacement cycle is longer, and it is also suitable for changing oil seals. The biggest advantage of box oil seal is that the processing requirements for shafts have been greatly reduced. It can be seen from the structure in the figure that the sealing lips do not contact the surface of the axis. Therefore, compared with ordinary oil sealing, the surface roughness and surface hardness requirements of the shaft have been greatly reduced. Therefore, the entire processing cost will also be reduced.
The main function of a deceleration oil seal is to isolate the internal structure and the external structure, so that the impurities, dust and water vapor of the external environment enter the internal, and the effect of affecting the use of components is worse. The effect of oil seal is large, but some oil seals are not satisfactory to use. This may be caused by some factors. It should be avoided to avoid the role of oil seal.
1. Improper storage
Oil seal is a precision component. Improper storage will definitely affect the use effect. If the purchased oil seal is not planned for the time being, then it should be stored in a place where the sun can be irradiated, or a high temperature. At the same time, the packaging of the oil seal is disassembled when it needs to be used, which can effectively avoid direct contact with the air.
2. Rough installation
If you want to have a good use effect, you can’t do without reasonable installation procedures. This is a very critical point that affects the effect of use. The correct installation should be applied to the appropriate lubricant, as much as possible to do as much as possible, and avoid mixing with other impurities. Do not operate too violently in the installation process, and it is easy to cause the installation position to tilt, which is a wrong way.
3. The quality of itself
In addition to the two points mentioned above, because of the different production techniques of various manufacturers, the use of oil sealing will be largely different. However, the quality of the oil seal itself is not clear, which can easily affect the effect of isolation and closed. This factor can directly show the effect of oil sealing. You must buy products with reliable quality and excellent technology as much as possible.
The above factors will affect the use of the oil seal, and the quality of the oil seal will directly reflect the problem. Therefore, when buying and selecting oil sealing, you must compare it first to ensure that the quality is reliable, and you should store it reasonably. The installation process should be operated according to the steps. Do not perfunctory things at will.
