Core Technology and Materials

Key technology centers on durable worm gear and worm wheel systems made from carburized alloy steel and high-tensile alloy bronze, offering low friction and high transmission efficiency. Worm gears have deeper teeth and dual lead worms with dual bearings for heavy cutting resistance and precision. Brake systems use multi-disc pneumatic or hydraulic brakes with braking torque 2-3 times higher than competitors, ensuring stable operation without backlash. Bearings are triple-constrained with enlarged diameters to support heavy loads.

Precision and Performance Specifications

Indexing accuracy is within 10 seconds of arc (standard 15 seconds), with repeatability as precise as 4 seconds. Products comply with ISO 230.2 standards suitable for aerospace and military use. CNC worm grinding and German CNC hobbing machines ensure worm and worm wheel precision to ±0.002 mm and 5 seconds respectively.
