IV. Material Characteristics
(A) Characteristics of Plastic Materials
- Light Weight: The density of plastics is much lower than that of metal materials. Using plastic spur gears can significantly reduce the overall weight of mechanical equipment. This is of great significance for some application scenarios that are sensitive to weight, such as aerospace and robotics.
- Corrosion Resistance: Engineering plastics have good corrosion resistance and can be used in harsh environments such as wet, acidic, and alkaline conditions, without being prone to rust and corrosion like metal gears. This makes plastic spur gears widely used in industries such as food processing and chemical engineering.
- Good Self - lubrication: Many engineering plastics have self - lubricating properties. During the transmission process, there is no need to add additional lubricating oil, which reduces maintenance costs and environmental pollution. At the same time, self - lubrication can also reduce gear wear and extend the service life.
- Low Noise: The elastic modulus of plastic materials is relatively low, which can absorb and buffer the vibration and impact during transmission, thereby reducing the noise of gear transmission. This is an important advantage for application scenarios with high noise requirements, such as office equipment and household appliances.
(B) Characteristics of Aluminum Alloy Materials
- High Strength: Aluminum alloy has a high strength - to - weight ratio. While ensuring the strength of the gear, the weight of the gear can be reduced. Compared with steel gears, the weight of aluminum alloy gears can be reduced by 30% - 50% under the same load - carrying capacity.
- Good Heat Dissipation: Aluminum alloy has a high thermal conductivity, which can quickly dissipate the heat generated during gear transmission, avoiding the decline of gear material performance and increased wear caused by overheating. This enables aluminum spur gears to perform better in high - speed and heavy - load transmission scenarios.
- Excellent Machinability: Aluminum alloy is easy to process and can be manufactured into various complex - shaped gears through various processes such as casting, forging, and machining. This provides greater flexibility for gear design and manufacturing and can meet the personalized needs of different customers.
- Good Surface Treatment Performance: Aluminum alloy can be subjected to surface treatments such as anodizing and electroplating to improve the wear resistance, corrosion resistance, and aesthetics of the gear. The surface - treated aluminum spur gears have a great improvement in both appearance and performance.
