helical worm gear

1 helical worm gear performance Characteristics
Systematic and modular design;Transmiss­ion ratio with fine stage covers a variety.
High efficiency; Low energy intake; Superior performance.
High Precision gearwith teeth grinding;Sta­ble transmission; Low noise; Solid bearing capacity; Long Services life.
Deft design: Small volume; Simple Installa­tion; Wide usage.
Suitable for all sorts of mounting positions
ES .. and ERF .. conjoined combination for special low velocity.
2 Material
Housing: High strength cast iron HT250, die casting lumen, reduce the abrasion of parts.
Gears: 20CrMo, Carbonitriding, Teeth 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 gets to 97%.
For some ways of installation, the input gear is totally immersed in the lubricant, please consider the churning loss with regards to big frame size and high input velocity .
