- Product Description
Large Spur Gear - Heavy-Duty Industrial Power Transmission Solutions
Henan Yizhi Machinery Co., Ltd. specializes in manufacturing precision Large Spur Gear frameworks planned for overwhelming mechanical applications. Our enterprise-level capabilities incorporate ISO-certified generation with 15 a long time of fabricating encounter, conveying customized adapting arrangements inside 35-60 days. We offer exactness grades ISO 5-6 and 8-9 with modules extending from 0.5–50, surface hardness up to 58–62 HRC, and comprehensive warm treatment forms counting carburizing and extinguishing. Our progressed fabricating combines producing, cutting, hobbing, processing, and pounding advances to guarantee uncommon quality and performance.

What Makes Our Large Spur Gear Superior?
When you require solid control transmission for heavy-duty applications, our product solutions convey unmatched execution. These mechanical transmission components include straight teeth cut parallel to the revolution pivot, designed particularly for high-load mechanical environments.
Our gears exceed expectations in applications where conventional adapting falls flat. They dispense with hub pushed loads, streamlining your bearing arrangements whereas diminishing lodging complexity. This plan advantage makes them perfect for parallel shaft control transmission frameworks requiring extraordinary durability.
Key Design Features
Your applications advantage from our gear's direct tooth geometry. The straight tooth profile produces zero hub strengths, anticipating pushed bearing disappointments that torment other adapt sorts. This auxiliary advantage gives prevalent resistance to bowing weariness and stun loads.
We fabricate each adapt utilizing high-grade combination steels counting 20CrMnTi, 40CrNiMo, and 18CrNiMo7. Our specialized warm treatment forms guarantee ideal surface hardness whereas keeping up center toughness.
