Precision M18 Helical Gear Fabrication for Heavy-Duty Rubber Machinery Restoration

The Challenge & Solution:

Operational downtime in tire production is often caused by the wear and tear of aging transmission components. For this project, we collaborated with a leading tire manufacturer in Qingdao to engineer high-performance replacements for their existing rubber machinery gearboxes. By replacing obsolete, worn-out gears with our custom-engineered M18 helical units, we successfully extended the equipment's service life and optimized torque transmission.

Project Parameters:

• Equipment Application: Industrial Rubber Machinery Gearbox

• Gear Architecture: Helical Gear (Designed for high-load, continuous-duty cycles)

• Module: M18 (Extra-large module for extreme industrial torque)

• Material Science: 20CrMnTi Alloy Steel (Engineered for high-stress environments)

• Batch Size: 2 Units (Matched precision pair)

• Technical Processing: Precision Gear Hobbing

• Heat Treatment: Quenching & Tempering (Ensuring excellent core toughness to withstand high torque)

• Tooth Surface Treatment: Carburizing & Tooth Surface Grinding (Achieving superior surface hardness and wear resistance)

• Precision Standard: DIN 7 (Ensuring smooth meshing and minimal heat build-up)

Engineering Highlights:

• Exceptional Load Capacity: The M18 large module design, combined with the core toughness of 20CrMnTi, allows these gears to handle the massive starting torques required in rubber processing without risk of tooth fracture.

• Advanced Surface Hardening: Through a rigorous carburizing and grinding workflow, we achieved a hard-wearing surface that maintains its profile integrity far longer than standard replacement parts.

• Seamless Retrofitting: Our engineers prioritized dimensional accuracy to ensure these 2 units functioned as a "drop-in" replacement, eliminating the need for complex modifications to the client's original gearbox housing.

Conclusion:

We specialized in reverse engineering for worn M18 gears to ensure perfect compatibility during restoration. This case highlights our ability to support the tire industry with critical spare parts and retrofitting services. By delivering these high-precision M18 gears, we empowered our client to revitalize their legacy machinery, ensuring a reliable and efficient production flow.
