ISO 5 Precision Custom Metal Worm Gear

Precision Advantages

ISO/DIN/GB Grade 5 precision (gear tolerance 5m): 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 m, 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 106 cycles (Grade 6 precision is 5105 cycles), with finite element analysis verifying more uniform tooth surface contact stress distribution.

Full specification coverage and material advantages

Standard module: 0.54 mm (customizable non-standard modules from 0.36 mm), reduction ratio 1080 (customizable 5100).

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.
