 According to the failure form of gear transmission, the basic requirements for the material properties of gears are that the tooth surface is complex, and the tooth center is challenging. According to the above conditions, the materials often used in gear designing: are forged steel, cast steel, cast iron, and metallic materials. Forged steel is the most commonly used material in gear design. The cast steel is frequently used for giant gears. The cast iron plant is used in situations where the operation is stable, the speed is low, and the power is insignificant.The non-metallic gears can reduce noise, which is often used in high speed, light load, and low progress. When designing the structure of the gear, we must comprehensively consider factors such as the gear's geometric size, blank, material, processing technology, use requirements, and economic factors. Usually, the appropriate structural form is selected according to the diameter of the gear, and then the structural design is completed based on empirical data.
