helical worm gear

1 Performance Characteristics
Systematic and modular design;Transmiss­ion ratio with fine stage covers a wide range.
High efficiency; Low energy consumption; Superior performance.
High Precision gearwith teeth grinding;Sta­ble transmission; Low noise; Strong bearing capacity; Long Program life.
Deft design: Small quantity; Simple Installa­tion; Wide usage.
Suitable for all kinds of mounting positions
ES .. and ERF .. conjoined mixture for special low quickness.
2 Material
Housing: High power cast iron HT250, die casting lumen, decrease the abrasion of parts.
Gears: 20CrMo, Carbonitriding, The teeth hard­ness: HRC 60 after grinding.
Flat keys: C45, Surface hardness: HRC 50.
3 Gear Unit Efficiency
High precision equipment; seals; bearings;Effecti­vely reduces friction; Stage helical worm gear efficiency of ge­ar drive reaches 97%.
For some means of installation, the input gear is completely immersed in the lubricant, please consider the churning loss with regards to big frame size and high input speed .
