CL Gear Coupling
- Typical Applications : Suitable for low-speed and heavy-load scenes such as metallurgy, mining, and lifting, and can adapt to temperatures of -40℃~45℃.
- Material : 45# steel or cast steel, tooth surface hardness HB300-350, drum-shaped tooth surface hardening treatment.
- Permissible torque : 710 N·m ~ 1,000,000 N·m (Drum tooth design has 15%-20% higher load capacity than straight tooth design).
-
Permissible speed :
3780 r/min (small model) ~ 300 r/min (large model), high-speed models require dynamic balancing.
