helical worm gear

1 Performance Characteristics
Systematic and modular design;Transmiss­ion ratio with fine stage covers a variety.
High efficiency; Low energy consumption; Superior performance.
High Precision gearwith teeth grinding;Sta­ble transmission; Low noise; Strong bearing capacity; Long Service life.
Deft design: Small volume; Simple Installa­tion; Wide use.
Suitable for all sorts of mounting positions
ES .. and ERF .. conjoined helical worm gear combination for special low rate.
2 Material
Housing: High power cast iron HT250, die casting lumen, reduce the abrasion of parts.
Gears: 20CrMo, Carbonitriding, Tooth hard­ness: HRC 60 after grinding.
Flat keys: C45, Surface hardness: HRC 50.
3 Gear Unit Efficiency
High precision gear; seals; bearings;Effecti­vely reduces friction; Stage performance of ge­ar drive reaches 97%.
For some ways of mounting, the input gear is totally immersed in the lubricant, please contemplate the churning loss when it comes to big frame size and high input speed .
