Double Plus Sprocket

Understanding Double Plus Sprockets

Double Plus sprockets are engineered for a specific type of conveyor chain known as Double Plus® chain (or free-flow chain). This chain design incorporates two roller sizes: smaller inner rollers that carry the chain tension and larger outer (top) rollers that support the conveyed product.

Key Characteristics & Function:

• Specialized Tooth Profile: The sprocket teeth are designed to mesh only with the smaller, inner load-carrying rollers of the Double Plus chain.
• Free-Rotating Top Rollers: The design ensures that the large top rollers of the chain do not contact the sprocket teeth, allowing them to rotate freely even when the chain is driven by the sprocket.
• Accumulation Capability: This free rotation of the large top rollers enables products on a conveyor line to stop (accumulate) against a barrier while the chain continues to run underneath without excessive friction or product damage. This makes them ideal as accumulation-conveyor-sprockets.
• Smooth Product Transfer: The large, free-rolling top surface provides a smooth platform for moving goods, crucial for smooth-transfer-sprocket applications.

Applications:

Double Plus sprockets are primarily used in accumulation conveyor systems found in automotive assembly lines, electronics manufacturing, food and beverage processing, logistics, warehousing, and packaging applications where items need to pause or buffer during the conveying process.
