Custom M18 Active Helical Gear Shafts for Rubber Machinery Reducers

Project Overview:
The active gear shaft is the heart of a reducer's power transmission. For a world-renowned tire manufacturer, we engineered and fabricated 2 units of high-torque helical gear shafts. This project focused on replacing critical drive components to enhance the stability and torsional rigidity of their industrial reducer units.

Key Specifications:

• Component Type: Active Gear Shaft (Helical design for input drive)

• Module: M18 (Heavy-duty drive module)

• Material: 20CrMnTi (Optimized for high-stress shaft applications)

• Quantity: 2 Units (Specialized precision matching)

• Processing: Precision Gear Hobbing

• Heat Treatment: Quenching & Tempering (Ensuring excellent core toughness and torsional rigidity)

• Tooth Surface Treatment: Carburizing & Precision Tooth Grinding (Enhancing surface hardness and wear resistance)

• Accuracy Class: DIN 7 (Ensuring precise alignment and transmission efficiency)

Engineering Highlights:

• Optimized Drive Dynamics: As an active gear shaft, this component must handle intense input speeds and torques. Our helical design ensures smooth engagement with the mating gear, reducing shock loads within the gearbox.

• Superior Torsional Strength: Fabricated from 20CrMnTi, the shaft undergoes a rigorous carburizing and grinding process, providing the necessary surface hardness to resist pitting and the core toughness to handle peak torsional stresses.

• Master-Level Alignment: With DIN 7 precision grinding, we ensured that the gear profile is perfectly aligned with the shaft axis, significantly reducing heat generation and extending the service life of the entire reducer assembly.
