Will the properties of a silicone rubber o-ring change when applied to gear oil?

Due to the richness of its application, silicone rubber o-rings can be used in many items. Today, I want to talk to you about the application of silicone rubber seals o-rings on gear oil. Gear oil is used as this sealing liquid. , it will have the necessary steam pressure. When using the silicone rubber o-ring, the ductility of the silicone rubber o-ring must be better, and it can integrate into the deformation caused by this type of steam pressure and extrude it. In the hydraulic transmission system, the hazard of gear oil (liquid) to the sealing properties of hydraulic seals, in addition to the compatibility of substances/rubber seals, the viscosity of refined oil, the change of viscosity with temperature, the rate of reciprocating (rotation) fitness , working pressure and shaft, engine block or hydraulic cylinder material, strength, geometric shape, surface smoothness, and the structure of hydraulic seals and other factors that endanger the production of the lubricating film and the characteristics of the film, all endanger the actual effect of sealing . In general, the creation of a sustained moisturizing film results in the desired sealing effect. Silicone rubber o-ring The Japanese NOK company first used the latest image processing technology to express the basic principle of the sealing of the clear frame seal. It is believed that the sealing principle of the skeleton seal (rotation dynamic sealing) consists of two parts: the lubrication characteristics and the basic principle of sealing. Lubrication characteristics: The friction characteristics of the skeleton seal are controlled by the viscosity and dragging rate of the fluid mechanics. The relativity between the skeleton seal and the shaft drags the surface layer to exercise under the lubrication condition separated by the oil slick, thus maintaining small friction and damage. Small. The basic principle of sealing: the fluidity of the oil on the drag surface of the skeleton seal is a circulation system in which the air side flows into the oil side and then flows from the oil side into the air side. The lubricating surface of the dragging surface is excellent, which can prevent the development of damage, so that there is no leakage. The basic theory of sealing is that there are layers of detailed moisturizing films in the middle of a dynamic soft sealing and mutual mating surfaces. Under normal circumstances, this layer of lubricating film is more relied on to exceed the purpose of sealing and increase the service life of hydraulic seals. When the exercise rate of the system software is too high, it will endanger the continuous production of the lubricating film, resulting in the increase of frictional heat, and exceeding the high temperature resistance range of the rubber seal will lead to the destruction of the hydraulic seal. When the working pressure is too large, in addition to the danger of oil slick, it will also cause damage to the hydraulic seals of rubber and plastic products.“Squeeze"Efficacy, usually optional“Flat Washers"to improve. Or choose PTFE with low friction resistance and good self-wetting to form a hydraulic seal structure, which will help to improve the lubrication in the middle of the friction pair. . Effective use of hydraulic seals and rubber seals, proper installation, application, and maintenance of hydraulic seals according to system software load standards and physical natural environment are important to obtain a reasonable sealing effect, reliability and service life. The gear oil does not have such strict requirements for the thickness of the silicone rubber o-ring, so everything is normal. Only the ductility of the silicone rubber o-ring is very high, so it is necessary to manufacture the silicone rubber o-ring. When ringing, in the raw materials that increase the ductility, the proportion must be adjusted again to facilitate the production of high-quality silicone rubber o-rings.
