The range of gear materials can be made from wood to the current synthetic material, including black metals, non -ferrous metals, powder metals and plastic. Ancient gears were found even made of stones. The selected material will affect the carrying capacity, strength, anti -point erosion, life and cost of the gear. The choice of gear material is complicated, and the choice will be based on service, manufacturing and economic requirements. First of all, the selection of gear materials should be based on the function required by the application, and must be related to the specific load and life required for the application. The compatibility of the material, chemical composition, ingredients, mechanical properties and costs of the material, chemical composition, ingredients, mechanical properties and costs must always be evaluated. According to gear application materials, its characteristics may require the characteristics of corrosion resistance and electrical or magnetic characteristics. 1. The gear material must meet the requirements of the working conditions. For example, the gear on the aircraft must meet the requirements of small quality, large transmission power, and high reliability. Therefore, it is necessary The dust content in the surrounding environment is extremely high, so it is often selected for cast steel or cast iron; the power of home and office machinery is small, but it is required to be stable, low noise or no noise, and it can be normal under less lubricating or lubricating state. Work, so engineering plastics are often used as gear materials. In short, the requirements for working conditions are the factors that should be considered first when choosing gear materials.
