| PEEK Gears and Carbon PEEK Gears, with high strength, achieve lightweight designs and serve as a plastic replacement for steel. Featuring self-lubricating properties, they operate without frictional noise and exhibit excellent resistance to high temperatures, wear, and fatigue. Their superior mechanical performance ensures stable operation under high pressure and high-speed conditions, while also extending service life. These gears are widely used in the automotive and drone industries. | |||||||||
Gears play a crucial role in the modern automotive industry. Whether in transmission systems or steering systems, the performance of gears directly impacts the efficiency, stability, and durability of the entire system. Traditional metal gears are typically manufactured through processes such as cutting and grinding, which often result in significant machining errors, high costs, and installation difficulties. Additionally, they tend to produce high levels of noise due to friction and are prone to damage during daily use. To overcome these challenges, finding high-performance gear materials has become a major trend in the automotive industry.
Compared to traditional metal materials, PEEK offers the following advantages when used to manufacture gears:
PEEK material has a high glass transition temperature and melting point, enabling it to withstand high-temperature working conditions while maintaining stable performance. Its long-term no-load service temperature can reach 260°C, with a glass transition temperature (Tg) of 143°C and a melting temperature (Tm) of 343°C.
PEEK's superior mechanical properties ensure that gears made from it can operate stably under high pressure and high-speed conditions. It exhibits high resistance to creep and fatigue, extending the service life of gear components.
PEEK achieves a UL94 V-0 rating without the need for flame retardant additives. Its self-extinguishing properties and low smoke emission make it suitable for stringent safety standards, and it is widely used in aerospace and military defense applications.
PEEK's excellent self-lubricating properties make it ideal for applications requiring low friction coefficients and wear resistance. This reduces friction and wear, minimizes energy loss and noise generation, extends gear life, and lowers maintenance costs.
With a density of only 1.3 g/cm³, PEEK is significantly lighter than common metals. Compared to metal gears, PEEK gears contribute to reducing the overall weight and inertia of equipment, improving efficiency and performance.
Reduced Manufacturing Costs: PEEK is easy to process, and injection molding can be used to manufacture complex gears while ensuring high precision and quality control. This provides greater flexibility in gear design.
Carbon fiber has extremely high strength and modulus. When added to PEEK, it significantly enhances the strength and stiffness of the gear. This allows PEEK-CF gears to withstand higher loads and resist deformation under high-stress conditions, ensuring transmission accuracy and stability while extending gear life. For example, in some industrial transmission systems, PEEK-CF gears can handle higher torque than pure PEEK gears, making them suitable for harsher working environments.
Carbon fiber's high hardness and excellent wear resistance enhance the wear resistance of PEEK material. As a result, PEEK-CF gears experience less wear on the tooth surfaces during long-term operation, maintaining better tooth profile accuracy and stable transmission efficiency. This makes them particularly suitable for gear transmission systems requiring frequent starts, stops, and high-speed operation.
Carbon fiber has a low thermal expansion coefficient. When combined with PEEK, it significantly reduces the gear's thermal expansion coefficient. This ensures better dimensional stability under varying temperature conditions, minimizing deformation and loss of meshing accuracy due to temperature changes. For instance, in precision instruments sensitive to temperature variations, PEEK-CF gears can enhance stability and reliability.
Carbon fiber has good thermal conductivity, which helps dissipate heat more effectively in PEEK material. As a result, PEEK-CF gears can dissipate heat better during operation, reducing working temperatures and preventing material performance degradation and lubrication failure caused by high temperatures. This improves transmission efficiency and extends gear life, especially in high-speed, high-load gear systems.
The addition of carbon fiber enhances the overall performance of the material, giving PEEK-CF gears better fatigue resistance than pure PEEK gears. Under long-term cyclic loading, PEEK-CF gears are less prone to fatigue cracks and damage, ensuring reliability and stability over extended operation periods. This reduces maintenance costs and downtime.
