Definition and classification of sprockets

A sprocket is a transmission device that transmits power or torque by connecting a chain to other sprockets or chains to gears. The sprocket consists of two main parts: the teeth and the wheel. The teeth are the protrusion on the sprocket used to bite the chain, and the wheel is the main structure of the sprocket, responsible for transmitting power and supporting the chain.

According to the shape and use of teeth, sprockets can be divided into the following categories:

Straight sprockets: The teeth of straight sprockets are arranged in a straight line, which is suitable for transferring small loads and speeds, and is often used in some low-speed applications, such as bicycles, motorcycles, etc.

Helical sprocket: helical sprocket teeth are inclined to arrange, can provide a larger transmission capacity, often used in industrial machinery and equipment, such as transmission machines, transport machines, etc.

Bent sprocket: bent sprocket teeth are curved shape, can provide less friction and noise in the transmission process, suitable for high noise requirements, such as printing machines, textile machines and so on.

Edged sprocket: Edged sprocket is a special shape of the sprocket, the top of its teeth have additional decorative edges, can provide better chain bite performance and transmission efficiency, often used in high load and high-speed transmission systems, such as automotive engines, aviation engines, etc.

These are the main categories of sprockets, and each type of sprocket has its specific application field and transmission characteristics, which need to be considered according to specific needs when choosing to use.
