Product Features

 

  • Features: The helical tooth meshing structure enables efficient power transmission with smooth operation and low noise. The worm's spiral design provides reverse self-locking to prevent equipment reversal and ensure safety. The compact structure adapts to space-constrained equipment layouts.
  • Material Introduction: Worm: High-strength alloy steel with heat treatment for enhanced wear resistance. Worm gear: Commonly uses antifriction alloys such as tin bronze to reduce meshing friction; gray cast iron is applied in cost-sensitive applications.
  • Advantages: It achieves large gear ratios in single-stage transmission to simplify equipment design. The compact design facilitates integration with smooth, low-noise operation. Reverse self-locking ensures safety in lifting equipment and withstands heavy loads.
  • Applications: In industrial manufacturing: machine tools, robotic arms, and automated conveying equipment. In lifting systems: safe transmission for elevators and escalators. In specialized fields: medical devices, aerospace, and marine power units.

 

Application

 

image001

Chemical Mixing Equipment: Applied in chemical reaction kettles for stirring raw materials. The worm gear reducer converts the high-speed rotation of the motor into low-speed rotation of the stirring shaft, increasing torque to adapt to high-viscosity materials. Its self-locking function prevents the stirring shaft from reversing.

Food Packaging Conveyor Line: Controls the conveyor belt speed to ensure stable transportation of food materials to packaging stations. It runs smoothly with low noise, meeting the hygiene requirements of food workshops.

Question

 

Q: What's the typical reduction ratio range of your worm gear reducers?

A: The typical reduction ratio range of our worm gear reducers is 5:1 to 100:1. Single-stage worm sets typically provide ratios of 10:1 to 50:1, while double-stage configurations can achieve higher ratios to suit low-speed, high-torque working scenarios.

Q: Can worm gear reducers achieve self-locking?

A: Yes. When the worm's lead angle is smaller than the friction angle (usually ≤3°), the reducer features a self-locking function, which prevents the worm gear from backdriving the worm. This makes it ideal for vertical lifting equipment or scenarios requiring position retention when power is off.

Q: What lubricants are recommended for food-grade applications?

A: For food-grade applications, NSF H1-certified synthetic lubricants (such as PTFE-based grease) are recommended. These lubricants comply with FDA standards, offering high stability, no odor, and no risk of food contamination, while maintaining gear transmission efficiency comparable to that of mineral oils.

 

Company introduction

 

One Of The Best Rack and Pinion Manufacturers In China
Kunshan Devotec Automation Co., Ltd. was established in 2012, but its origins trace back to an initial investment by the German company WMH HERION in Qingdao, Shandong Province in 2007. Since then, we have accumulated extensive experience in engineering, manufacturing, and quality control. As a specialist in drive technology, Kunshan Devotec Automation focuses on the production of high-precision gear racks, gears, pinions, gearboxes, linear guideways, and other linear transmission components.
