Product Description
A chain sprocket is a profiled wheel with teeth that mesh with a chain. It is a fundamental component of a chain drive system, which is used for positive power transmission, conveying, or indexing. Unlike gears, sprockets are never meshed with other sprockets; they work in a pair with a chain.
Key Features and Purpose
-
Positive Drive: The primary function of a chain and sprocket system is to provide a positive drive, meaning there is no slippage between the sprocket teeth and the chain. This makes them highly efficient for transmitting power and maintaining speed ratios.
-
Toothed Design: The teeth of a sprocket are precisely shaped to fit the links of the chain. The size of the teeth and the distance between them (known as the pitch) must match the chain pitch for smooth operation and to prevent premature wear.
-
Material: Sprockets are typically made from steel, cast iron, or other durable materials to withstand high loads and abrasion. For high-performance applications, they can be hardened to extend their service life.
-
Types: Sprockets come in various types to accommodate different chain configurations:
-
Simplex: Designed for a single-row chain.
-
Duplex: Designed for a double-row chain, for higher power transmission.
-
Triplex: Designed for a triple-row chain, used in heavy-duty applications.
