Worm gear

spiralshaftedflange

ISO/DIN/GB Grade 5 precision (gear tolerance ≤5μm): 40% reduction in backlash compared to traditional Grade 6 precision, with a 15% increase in transmission efficiency. Single-lead worm gear backlash of 3-5 arc minutes, adjustable to 1-3 arc minutes for double-lead, specifically designed for precision transmission applications such as servo motors and robot joints. Utilizing shaving process + helix angle optimization, surface roughness Ra ≤ 0.8 μm, with noise levels below 60 dB for 1-2 head worm gears (conventional 7-grade precision noise ≥ 65 dB). Grade 5 precision worm gears have a fatigue life of 10^6 cycles (Grade 6 precision is 5×10^5 cycles), with finite element analysis verifying more uniform tooth surface contact stress distribution. Full specification coverage and material advantages Standard module: 0.5–4 mm (customizable non-standard modules from 0.3–6 mm), reduction ratio 10–80 (customizable 5–100). Matching worm gears and non-standard customization capabilities Worm gears are processed on the same production line, ensuring matched tooth surface hardness and high meshing accuracy. Custom processing available for special tooth profiles (involute/normal straight profile), non-standard installation distances (±0.01mm tolerance), and irregular hole diameters (spline holes/step holes), as well as corrosion-resistant coatings (Ni-P plating), high-temperature alloys (e.g., Inconel), and noise-optimization (tooth tip profiling) customization requirements.
