Sprockets are a toothed wheel with a central bore, which is mounted onto a shaft, and the teeth mesh with the links of a chain, transmitting power from the driving shaft to the driven shaft.
Types Of Sprockets
- Standard sprockets: These are the most common type of power transmission sprockets and are used in a wide range of applications. They have a standard pitch and tooth profile and are available in various sizes.
- Idler sprockets: These sprockets are used to maintain tension in the chain and prevent it from sagging. The idler sprockets are typically used in applications where the chain has a long span between the drive and driven sprockets.
- Double sprockets: These sprockets have two sets of teeth and are used in applications where two single chains need to be driven from a single shaft. This allows machines to provide power to two different driven shafts from the main sprocket drive.
- Taper-lock sprockets: These sprockets have a tapered bore and are designed to be mounted directly onto a shaft without the need for a separate keyway or set screw.
- QD sprockets: These sprockets have a quick-disconnect mechanism that allows them to be quickly and easily mounted onto a shaft without the need for a separate keyway or set screw.
- Stainless steel sprockets: These sprockets are made from stainless steel and are ideal for use in corrosive environments where standard steel sprockets would quickly deteriorate.
