High-Performance Industrial Worm Gears & Worm Shafts: 20 Years of Precision Engineering
1.1.1 1. Introduction: The Pinnacle of Power Transmission
At the heart of modern industrial automation lies the need for smooth, quiet, and high-torque power transmission. With over two decades of specialized manufacturing experience, our factory has perfected the art of producing high-precision Worm Gears and Worm Shafts.
Worm gearing is a unique solution where a worm (a gear in the form of a screw) meshes with a worm gear (similar in appearance to a spur gear). This configuration allows for high reduction ratios in a compact space, making it an indispensable component in heavy-duty machinery.
1.1.2 2. Why Choose Our Worm Gear Systems?
Our 20-year journey in the transmission industry has taught us that reliability is non-negotiable. Our products are engineered to provide:
High Reduction Ratios: Achieve significant speed reduction and torque multiplication within a single stage.
Self-Locking Capability: Depending on the lead angle, our worm gears can act as a natural brake, preventing back-driving and enhancing safety in lifting applications.
Quiet and Smooth Operation: The sliding contact nature of worm gearing results in significantly lower noise levels compared to spur or helical gears.
Space Efficiency: The right-angle configuration allows for compact gearbox designs, ideal for tight industrial footprints.
1.1.3 3. Material Excellence & Technical Specifications
A gear is only as good as the material it is made from. We utilize a combination of premium alloys to ensure a balance between strength and friction reduction.
| Component | Standard Material Options | Treatment |
| Worm Shaft | 20CrMnTi, 40Cr, 42CrMo Steel | Case Hardening (HRC 58-62), Nitriding |
| Worm Wheel | ZCuSn10P1 (Tin Bronze), Aluminum Bronze, Nylon | Centrifugal Casting for high density |
1.1.1 4. Advanced Manufacturing Process
Our factory utilizes a vertically integrated production line. Having managed our own facility for 20 years, we have optimized every step:
Precision Forging: We start with high-density blanks to eliminate internal voids.
CNC Worm Grinding: We use state-of-the-art Reishauer or similar high-precision grinding machines to ensure the worm profile is perfect, reducing friction and heat.
Hobbing & Centrifugal Casting: Our worm wheels are produced using centrifugal casting for bronze rings, ensuring a grain structure that resists wear better than standard sand casting.
Heat Treatment: Our in-house heat treatment facility allows for precise control over the case depth and hardness of the worm threads.
1.1.2 5. Rigorous Quality Control (QC)
"Quality is the lifeblood of a factory." Every gear set that leaves our facility undergoes a multi-stage inspection process.
Coordinate Measuring Machine (CMM): To verify complex geometries and lead accuracy.
Contact Pattern Testing: We perform "blueing" tests to ensure the contact area between the worm and gear is centered and optimized for load distribution.
Hardness Testing: Verification of the Rockwell or Vickers hardness to guarantee long-term wear resistance.
Surface Roughness Analysis: Ensuring the worm thread surface is mirror-finished to minimize the coefficient of friction.
| Module Range: | 0.5 – 25 Mod |
| Accuracy Grade: | DIN 5 to DIN 9 / AGMA 10-12 |
| Pressure Angle: | 14.5°, 20°, or customized per client blueprints. |
| Structure: | Solid wheel, bolted ring, or composite casting. |
Our transmission components are trusted by engineers worldwide across various sectors:
