High-Precision Hardened Gear Ring Processing Technology – Henan Sankuang Machinery Tech
As the core component of high-torque transmission, the gear ring’s tooth profile accuracy and flank intensity are key to transmission stability. Henan Sankuang Machinery Technology possesses comprehensive gear ring manufacturing capabilities, from forming and heat treatment to finishing.
We utilize precision mold forming and powder metallurgy sintering to ensure the density and consistency of the gear blank . For critical heat treatment, we employ local high-frequency induction hardening, precisely heating the tooth section. Combined with water-solvent quenching and low-temperature tempering, this process achieves a high-hardness tooth flank while effectively controlling deformation and maintaining core toughness . During post-processing, we strictly perform turning of the outer diameter and end faces, ensuring coaxiality and burr removal to meet stringent installation and transmission accuracy requirements . For large mining machinery, reducers, and mill drive systems, we offer customized, high-reliability, and long-life gear rings 。
