helical worm gear

1 Performance Characteristics
Systematic and modular design;Transmiss­ion ratio with good stage covers a wide range.
High efficiency; Low energy usage; Superior performance.
High Precision gearwith teeth grinding;Sta­ble transmission; Low noise; Solid bearing capacity; Long Service life.
Deft design: Small quantity; Simple Installa­tion; Wide use.
Suitable for all sorts of mounting positions
ES .. and ERF .. conjoined combination for special low speed.
2 Material
Housing: High strength 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 effectiveness of ge­ar drive gets to 97%.
For some means of installation, the input gear is helical worm gear completely immersed in the lubricant, please consider the churning loss with regards to big frame size and high input speed .
