The normal operation of the entire conveyor or conveying system largely depends on the quality of the chain drive. Choosing the sprocket correctly is as important as choosing the chain. Firstly, the design selection of the chain and sprocket must be consistent. Simply put, the sprocket and the matching chain should be of the same standard specification to ensure good meshing.

Standard sprockets are divided into two basic types: semi precision (cast teeth, flame cutting teeth) and precision (cutting teeth). The difference lies in their meshing and operation with the chain. sprockets with cutting teeth operate smoothly and have low noise, and are generally used in medium and high-speed conveying applications But it may not be suitable for low-speed, large pitch conveying situations: sprockets with cast or flame cut teeth have low cost and sufficient lifespan when paired with engineering steel chains. The medium and high-speed conveyor chain sprockets of general short pitch precision roller chains (GB/T 1243) and toothed chains (GB/T 10855) are made of steel or cast iron materials, and the gear teeth are mechanically cut and processed, and the gear tooth surface is precision machined when interacting with the chain. The sprocket materials of low-speed large pitch engineering steel conveyor chains are mostly made of steel or cast iron materials, and the gear teeth are cast or flame cut; The sprocket material of a flat top conveyor chain is generally made of steel, cast iron, or engineering plasticMaterials, steel and cast iron gear teeth are machined by mechanical cutting, and engineering plastic gear teeth are injection molded, but there are also many exceptions, especiallyIt is in the field of engineering transportation. In any case To ensure the design and precision level of the sprocket, as well as the surface accuracy of the interaction between the sprocket and the chainMust match with the chain.
