These products are integral to various industrial reducers. They demand high load-bearing capacity, smooth transmission, and low noise levels. Currently, gears for industrial reducers predominantly utilize gear grinding processes, which significantly enhance product quality. Depending on the product's application, materials like 20CrMnTi and 20CrMnMo (low carbon alloy steels) are typically selected. These undergo carburizing and quenching heat treatment, achieving a tooth surface hardness of HRC58-62 for superior wear resistance.
Products for high-precision oil pumps have unique requirements. Oil pump gears demand very small or no tooth chamfering to ensure sufficient oil inflow and outflow during operation. Furthermore, extremely high precision and surface roughness are critical to minimize temperature variations caused by high-speed operation, which could otherwise affect oil volume.
Oil pump gears operate under demanding conditions, so materials like 18CrNiMo7-6, 17CrNiMo6, and 20Cr2Ni4A are typically chosen for their superior performance and enhanced impact resistance. The tooth surface hardness can reach HRC58-62.
