Robust Gears for Heavy Transmission Systems

Large module gears are key components in heavy-duty transmission systems. Larger module values provide larger tooth profiles and higher load capacity. Our products cover module ranges from m3 to m12. These gears are widely used in mining equipment, metallurgical machinery, and heavy-duty reducers. Tooth size directly affects gear strength and durability under high-load operating conditions. We have extensive experience manufacturing large module gears for demanding industrial applications.

Precise Tip Circle Control for Proper Meshing

Tip circle accuracy is one of the key technical challenges in large module gear machining. The tip circle directly affects meshing clearance and tooth root strength. We control tip circle tolerances within ±0.025 mm and achieve Grade 7 precision. For maximum-size specifications, we maintain overall dimensional tolerances within ±0.03 mm and achieve Grade 9 precision. This strict tolerance control ensures accurate meshing between mating gears. Proper meshing helps reduce premature wear and improves the service life of transmission systems.

Extensive Experience in Large Gear Manufacturing

Our company has supported the heavy machinery industry since 2007. We have established quality management procedures, including 8D reports and one-page quality analysis reports, to handle production issues efficiently. Our team follows the "Three No" quality principle to prevent defective products from entering the next process. Our CNC gear hobbing machines and gear shaping machines are capable of manufacturing large module gears with stable accuracy. We regularly maintain fixtures and cutting tools to keep consistent tooth profile quality throughout production. This manufacturing approach helps ensure reliable performance across production batches.

Service Designed Around Your Project Schedule

Custom sample development for large module gears typically takes 15 to 30 days. Batch production lead times range from 30 to 90 days depending on tooth quantity and machining complexity. We provide flexible payment options based on project requirements. For large-volume orders, we offer tiered pricing solutions. We also support batch delivery schedules according to customer needs. This flexibility helps customers manage inventory planning and project timelines effectively.
