High-Performance Worm Gears for Elevator Traction Machines

The Heart of a Smooth, Safe, and Reliable Elevator Hoist

In an elevator's traction machine, the worm gear is the critical component responsible for converting the motor's high-speed rotation into the high-torque, low-speed motion needed to lift the cabin. Its performance directly impacts ride quality, noise level, and, most importantly, operational safety. Failure is not an option.

Yile Machinery specializes in manufacturing robust and precise worm wheels (worm gears) for elevator hoist motors. We engineer our gears using a proven two-piece construction that provides exceptional performance and value, meeting the stringent demands of the vertical transportation industry.

Key Features & Benefits:

• Superior Wear Resistance: The gear ring is forged from high-quality phosphor bronze or tin bronze, materials renowned for their low friction and excellent resistance to wear when meshing with a steel worm shaft. This ensures a long, reliable service life.

• Cost-Effective & Robust Design: Our two-piece assembly features a forged bronze gear ring securely mounted onto a high-strength cast iron hub. This intelligent design provides the critical performance of a bronze gear where it's needed most (the teeth) while reducing overall material cost and weight.

• Precision CNC Hobbing: Each gear is manufactured using precision CNC gear hobbing machines. This process guarantees a perfect tooth profile for smooth, quiet engagement with the worm shaft, minimizing vibration and ensuring a comfortable ride for passengers.

• Custom & Replacement Manufacturing: We produce gears directly from your technical drawings for new elevator models. We also specialize in reverse engineering worn or failed gears to provide dimensionally identical, drop-in replacements for maintenance and repair.
