In the global industrial system, metric spur gears, as the core components of mechanical transmission systems, have become the common language in the field of multinational manufacturing with their standardized design and reliable performance. This type of gear is dimensioned using the International System of Units (SI), and its pitch, module and other parameters strictly follow ISO international standards to ensure seamless connection in the global supply chain.
From the technical characteristics, the module system of metric spur gears achieves precise control of the transmission ratio. Taking the module m=2 as an example, the pitch diameter of the gear is fixed as the product of the number of teeth and the module. This simplified calculation method provides great convenience for mechanical design. Its involute tooth design maintains a constant pressure angle during the meshing process, which not only reduces transmission noise but also improves power transmission efficiency. Under heavy load conditions, tooth surface quenching or carburizing can effectively improve wear resistance.
Current market data shows that the penetration rate of metric spur gears in machine tools, textile machinery, logistics equipment and other fields has reached more than 75%. Especially in the context of the booming new energy vehicle industry, precision-made metric spur gears combined with harmonic reducers are playing a key role in the innovation of drive systems. As the process of intelligent manufacturing accelerates, smart gears equipped with sensors are beginning to appear, which can monitor torque fluctuations and temperature changes in real time.
International trade rules require that export-oriented metric spur gears must be certified according to the ISO 6336 gear strength calculation standard. When selecting suppliers, buyers should not only pay attention to material properties (such as 20CrMnTi carburizing steel), but also examine whether the detection methods are complete, including three-coordinate measurement and tooth interference analysis. This standardized feature makes metric spur gears an ideal choice for cross-border procurement.
