helical worm gear

1 Performance Characteristics
Systematic and modular design;Transmiss­ion ratio with good stage covers a wide range.
High efficiency; Low energy consumption; Superior performance.
High Precision gearwith teeth grinding;Sta­ble transmission; Low noise; Solid bearing capacity; Long Support life.
Deft design: Small quantity; Simple Installa­tion; Wide utilization.
Suitable for all types of mounting positions
ES .. and ERF .. conjoined combination for special low swiftness.
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 equipment; seals; bearings;Effecti­vely reduces friction; Stage effectiveness of ge­ar drive reaches 97%.
For some ways of installation, the input gear is completely helical worm gear immersed in the lubricant, please contemplate the churning loss when it comes to big frame size and high input rate .
