Drag Chain Conveyor – Sprocket & Shaft Assemblies
The Sprocket & Shaft Assembly is a critical component in drag chain conveyor systems, providing the driving torque to move the chain and the conveyed material efficiently. Constromech Solution offers precision-engineered sprocket assemblies tailored for drag conveyors, ensuring optimal engagement, reduced wear, and reliable operation under heavy-duty conditions.
Technical Highlights & Construction Features
| Feature | Technical Detail |
| Sprocket Profile | Custom tooth geometry for drag chain flights; precision-cut to match chain pitch |
| Material | High-strength alloy steel (42CrMo or equivalent) forged for durability |
| Heat Treatment | Carburized teeth with surface hardness 55–60 HRC; core toughness maintained |
| Dynamic Balancing | Balanced to ISO G 6.3 to reduce vibration and extend bearing life |
| Shaft Design | Solid or hollow shafts with keyways, stress-relieved for shaft rigidity |
| Mounting System | Split-hub or taper-lock bushings for quick installation and replacement |
| Sealing & Protection | Labyrinth seals or grease seals keep contaminants out of bearings |
Application Advantages in Drag Conveyors
• Optimized tooth engagement minimizes chain and flight wear
• Robust shaft design prevents deflection under high torque
• Modular sprocket segments allow in-situ replacement without shaft removal
• Sealed bearings and protective coatings extend service intervals
• Balanced assemblies reduce noise and increase conveyor uptime
