The chain sprocket on a paver's auger (screw conveyor) is a critical component of the drive system, transmitting power to the auger shaft for even asphalt mix distribution. Key features include:
1. Material & Craftsmanship: Typically forged from alloy steel with heat treatment for wear resistance, featuring high-precision tooth profiles for smooth operation.
2. Structural Design: Often dual-row sprockets paired with heavy-duty roller chains; some models integrate sealed bearings to minimize wear and contamination.
3. Function: Adjusting the sprocket speed ratio controls auger rotation, influencing paving thickness and material uniformity.
Maintenance requires regular checks of chain tension and sprocket tooth wear to prevent slippage or failure. Brands like Vögele and Volvo offer modular sprocket designs for quick replacement.
