Heavy Duty Drum Gear Coupling | Angular Misalignment 1°30' · 99.7% Efficiency · Life Extended to 18+ Months | Henan Sankuang Machinery
Drum gear couplings are suitable for low-speed, heavy-load conditions in metallurgy, mining, and crane transport. Transmission efficiency: up to 99.7%.
Actual Delivery Case: In 2024, a mining belt conveyor drive system originally used straight-tooth couplings. Foundation settlement caused approximately 0.8° angular misalignment, resulting in severe edge loading and wear with service life under 6 months. After switching to our drum gear couplings (1°30' angular compensation), service life extended to over 18 months, reducing client maintenance costs by approximately 65%.
Core Design Advantages:
Load capacity: 15-20% higher than straight-tooth couplings
Angular misalignment: Up to 1°30', 50% better than straight-tooth types
Contact conditions: Crowned tooth profile eliminates edge loading and stress concentration
Easy assembly/disassembly: Bell-mouthed tooth ends on outer sleeve
Manufacturing Process: Forging → Normalizing → Rough Turning → Gear Hobbing (crowned tooth tooling) → Carburizing + Hardening (HRC 58-62) → Gear Grinding → Dynamic Balancing.
Material: 42CrMo or 45# carbon steel forgings, tooth HRC 58-62, core HRC 30-35.
