Sprocket

Sprocket, also known as a chain wheel, is a mechanical component designed to mesh with a chain. It typically features a series of evenly spaced teeth around its circumference. These teeth engage with the links or rollers of the chain to facilitate the transmission of power and motion between different parts of a mechanical system.

 

Types:

• Plate sprocket(Type A): Provided as a flat plate with no hub. This enables you to drill and mount the sprocket on your machine without having a hub.
• Idler Sprocket: Spin freely on built-in bearings to guide and control slack in your chain. Idler sprockets are self lubricating andquiet, will extend the lifetime of a roller chain and sprocket.
• QD Sprocket: A specially designed sprocket, the “QD” in its name stands for “Quick Detachable”. The QD bushing is a tapered sleeve that can be easily installed and removed.
• Tapered Bushing Sprockets (TL): Bushing bore sprockets for ANSI Roller Chain. Change bore size without replacing sprocket. Easy to install, more flexibility.
• Double single sprocket(Type SD): Used in applications where two or more items are powered by a common drive shaft.
• Split sprocket: Cut through the entire diameter for ease of installation and removal. For applications that are limited in space, or require more frequent maintenance.
• Duplex Sprocket(Type C): The duplex sprockets are usually made of mild steel and sometimes of stainless steel in many different sizes.
• Finished bore sprocket(Type B): Associated with B- and C-style sprockets, where the inside diameter of the hub is machined to accommodate a specific shaft diameter.
• Plain bore sprocket(Type B): Associated with A-, B- and C-style sprockets, where there is no special machining performed to accommodate keyways or set screws, only a hole to accommodate shaft diameter.

 

Materials:

• Steel: Through proper heat treatment and surface treatment with its high strength, hardness, good workability and certain wear resistance.
• Stainless steel: Highly resistant to rust,suitable for applications where exposure to moisture or chemicals is a concern. But have lower tensile strength than steel material.
• POM: Made of durable polymer materials has the advantages of wear resistance and noise reduction compared with similar metal products. Lighter and more cost-effective.

 

Surface Treatment:

• Black Oxide: Forms a black oxide layer on the surface of the sprocket, which provides some corrosion resistance and a certain degree of lubricity.
• Galvanization (Zinc Coating): A layer of zinc is deposited on the surface of the sprocket through electroplating. Provides corrosion resistance and extends the sprocket’s lifespan.
• Chrome Plating: Has a hard and shiny surface. Offers a hard, wearresistant surface that can also enhance the appearance of sprockets, often used for decorative or functional.
• Nickel Plating: Used to improve the hardness and corrosion resistance of sprockets, as well as to provide a smooth, shiny surface finish. Suitable for environments where zinc or copper cannot be used, such as in the lithium battery industry.
• Hard Anodizing: Primarily used for aluminum alloy sprockets, this process forms a thick oxide film on the surface, enhancing hardness, wear resistance, and corrosion resistance.

 

Key Features:

• High Efficiency: Chain sprockets transmit power through positive engagement with chains, ensuring minimal slippage and high efficiency..
• Good Wear Resistance: Due to the materials used and oftenapplied surface treatments such as plating or heat treatment, sprockets have good wear resistance.
• Customizable:Chain sprockets can be customized to specific requirements, such as special sizes, tooth profiles, and materials.
• Precision:Accurate pitch and tooth profile ensure smooth and reliable chain movement.
• Versatilityand Durability: Available in various sizes and tooth configurations to suit different power transmission needs. Withstand high loads and resist wear in demanding environments.

 

Heat Treatment:

• Quenching & Tempering: Heats sprocket, quenches to harden surface (martensite), then tempers to reduce brittleness.
• Induction Hardening: Core remains tough; ideal for medium-carbon steels (e.g., 45 steel) to boost wear resistance.
• Carburizing Quenching: Surface hardness reaches HRC 58–62, while core stays ductile.
• Nitriding: Minimizes distortion; suits alloy steels (e.g., 38CrMoAl) for high wear/corrosion resistance.

 

Simple Structure:

Easy to install, easy to assemble and disassemble. They can be easily mounted on shafts or hubs using appropriate fasteners.

 

Application Scope:

Sprockets are widely used in various mechanical applications. Such as industrial machinery, conveyor systems, automotive industry,material handling systems, robotics, packaging machinery,food processing equipment an so many other heavy machinery.
