Do rubber parts for gearbox have the characteristics of high temperature resistance and anti-aging?
Publish Time: 2024-12-19
In the automotive manufacturing industry, the gearbox is the core component of power transmission, and its performance and reliability are directly related to the operating efficiency and safety of the whole vehicle. Inside the gearbox, rubber parts play a vital role. They are not only used for sealing and shock absorption, but also undertake multiple functions such as connection and fixation. Given that the gearbox generates a lot of heat during operation and is exposed to a variety of chemicals, the high temperature resistance and anti-aging properties of rubber parts for gearbox are particularly important.Rubber parts for gearbox mainly include O-rings, gaskets, oil seals, etc. These rubber parts play a sealing role inside the gearbox to prevent oil leakage and ensure the normal operation of the gearbox. However, the gearbox will generate high temperature when working, especially when driving at high speed, climbing or working continuously for a long time, the oil temperature may exceed 100℃ or even higher. In such a high temperature environment, ordinary rubber parts are easy to age, deform, and harden, resulting in reduced sealing performance and oil leakage, thereby affecting the lubrication effect and performance of the gearbox.The application of high temperature resistant rubber materials is the key to solving this problem. For example, fluororubber is widely used in the manufacture of rubber parts for gearbox due to its excellent high temperature resistance and chemical corrosion resistance. Fluororubber can work stably in the temperature range of -20℃ to +200℃. It is not only resistant to high temperature, but also resistant to corrosion and can resist erosion by various chemical substances. In addition, silicone rubber is another commonly used high temperature resistant rubber material, with an operating temperature range of 100-300℃ and excellent weather resistance and ozone resistance.In addition to high temperature resistance, anti-aging performance is also an important consideration for rubber parts for gearbox. Rubber aging refers to the fatigue caused by oxidation of oxygen and ozone in the air, light, temperature and mechanical deformation during storage and use of rubber, which leads to changes in the elasticity, hardness, anti-swelling and insulation of rubber, discoloration, stickiness or hardening, brittle cracking and other phenomena, and eventually loses its use value. Once the rubber parts for gearbox age, the sealing performance will be greatly reduced, which may cause oil leakage, and even affect the normal operation of the gearbox in severe cases.In order to improve the anti-aging performance of rubber parts for gearbox, manufacturers usually take a variety of measures. On the one hand, by optimizing the rubber formula and adding antioxidants, anti-ultraviolet agents and other additives, the aging resistance of rubber can be improved; on the other hand, by improving the production process, such as using plasma treatment and other technologies, the rubber surface can be cleaned, impurities such as oil stains and oxide layers can be removed, and the hydrophilicity and roughness of the rubber surface can be enhanced, thereby improving the sealing performance and durability of rubber parts.In addition, regular maintenance and inspection are also important means to extend the service life of rubber parts for gearbox. Car owners should regularly replace the gearbox oil to avoid oil deterioration and contamination, and check the status of rubber parts for gearbox at the same time. If there are aging, deformation, hardening and other phenomena, they should be replaced in time.High temperature resistance and aging resistance are important performance requirements for automotive rubber parts for gearbox. By selecting high temperature resistant rubber materials, optimizing formulas and production processes, and strengthening maintenance and inspection, the high temperature resistance and aging resistance of rubber parts for gearbox can be effectively improved, thereby ensuring the normal operation of the gearbox and extending the service life of the car. For car manufacturers and car owners, paying attention to the performance and quality of rubber parts for gearbox is an important part of ensuring the safe and reliable operation of the car.
