Large-Module Bronze Worm Wheels for Heavy Industrial Applications

Yile Machinery is a leading manufacturer of custom, large-module bronze worm wheels. As the heart of high-torque worm drive systems, these gears are engineered to withstand extreme loads in the most demanding industrial environments. We specialize in producing high-integrity replacement worm wheels that meet or exceed original equipment specifications, minimizing downtime and extending the life of your critical machinery.

The Core of a Reliable Worm Drive: Superior Material & Manufacturing

In a worm gear set, the bronze worm wheel is designed to be the conformable component, meshing with a hardened steel worm. Its quality directly dictates the performance, efficiency, and service life of the entire gearbox. We ensure excellence through two key areas:

1. High-Performance Bronze Alloys: We use specific bearing-grade bronze alloys selected for their combination of strength, wear resistance, and low friction. Common choices include:

• Tin Bronze (e.g., ZCuSn10Pb1 / C93200): The industry standard, offering excellent load-carrying capacity and anti-seize properties.

• Aluminum Bronze (e.g., ZCuAl9-4 / C95400): Offers higher tensile strength and is ideal for applications with very heavy shock loads.

2. Superior Casting Method: Centrifugal Casting:

For large worm wheels, we utilize centrifugal casting to produce the bronze ring blanks. This method spins the mold at high speed, forcing the molten metal outward and creating a part that is:

• Exceptionally Dense & Pure: Impurities are forced to the center and machined away.

• Completely Free of Porosity: Eliminates internal voids that can lead to catastrophic failure under load.

• Structurally Superior: Results in a refined, uniform grain structure for maximum strength and wear resistance.

Precision CNC Machining for a Perfect Mesh

After casting and heat treatment, the bronze blank is precision machined on our large-format CNC equipment.

• CNC Turning: The blank is machined to its precise dimensions.

• CNC Gear Hobbing: The gear teeth are cut using specialized, large-capacity hobbing machines. This process ensures the highest accuracy of the tooth profile, pitch, and lead angle, guaranteeing a smooth, quiet, and efficient mesh with the worm.

• Final Inspection: Every gear is verified using CMM equipment to ensure all critical dimensions are within tolerance before shipment.

Reverse Engineering: Your Solution for Emergency Breakdowns

Have a failed worm wheel but no technical drawing? We can help.

Our reverse engineering service is designed for critical repair and maintenance situations. We can take your worn or broken sample part and create a new, production-ready drawing. Our process includes:

• Full dimensional analysis of the sample.

• Material testing (spectrometry) to identify the original bronze alloy.

• Creation of a new CAD drawing for your approval.

• Manufacturing of a brand-new worm wheel that fits perfectly.

This service is your fastest path to getting your essential machinery back online.
