This worm gear set is specifically for worm gearbox. It uses high-strength materials, precisely controls heat treatment, and high precision accuracy levels to ensure reliable performance in power transmission applications.
The worm wheel is produced from CuSn12Ni2, known for superior resistance to wear and seizure under sliding contact conditions. The worm uses 20CrMnTi material, GB standard case-hardening steel, carburizing heat treatment reach hardness 58-62HRC, forms a hardened surface layer while preserving a tough, impact-resistant core. This material pairing improves the gear unit’s ability to withstand both continuous friction and intermittent shock loads.
In terms of manufacturing precision, the worm wheel is manufactured to DIN 8 accuracy, while the worm shaft meets DIN 6. The tighter tolerance on the worm shaft (DIN 6) minimizes transmission error and backlash, contributing to smoother motion control and quieter operation. The DIN 8 rating on the wheel represents a practical balance between production economy and reliable meshing behavior.
Worm gears, thanks to their carefully selected materials, heat treatment, and precision, offer excellent durability and operational stability in worm gear reducer environments.
