Heavy-load Adaptive Input Shaft High Gear

Input shaft high gear is the core hub of power input and transmission in the power transmission system, specially adapted to precise power conversion under high-speed working conditions, providing stable transmission guarantee for high-end equipment. Its precision advantage lies in full-process precision control, adopting five-axis linkage machining + tooth profile correction technology, the cumulative pitch error is ≤ GB/T 10095.1-2008 grade 6 standard, the tooth surface roughness reaches Ra0.8μm after superfinishing, and the meshing gap is controlled at 0.02-0.05mm, which greatly reduces transmission impact and energy loss. The impact resistance and heavy load resistance are guaranteed by both material and process. High-strength 20CrMnTiH carburized steel is used, and after carburizing quenching + low-temperature tempering treatment, the tooth surface hardness HRC58-62 forms a wear-resistant layer, and the core HRC30-40 ensures toughness, which can withstand instantaneous impact of…
