The product is built on a high-quality alloy steel substrate, featuring an innovative tooth-column curvilinear meshing zone design. The curved structure precisely aligns with the transmission engagement trajectory, minimizing meshing stress and frictional losses at the source. During production, integral precision forging enhances material density to solidify the structural foundation, while high-precision machining centers ensure precise alignment of bore diameters and positions for optimal installation compatibility. Finally, a multi-tooth-column quenching process strengthens critical components, achieving a stable tooth-column hardness exceeding HRC55. This comprehensive approach guarantees exceptional transmission wear resistance, installation accuracy, and operational stability.
