Made In China Sprockets For Standard Conveyor Chains
Comprehensive Guide to Made-in-China Conveyor Chain Sprockets
Conveyor chain sprockets serve a vital role in transferring motion and power within conveyor systems by interacting with the conveyor chains. In essence, these components are toothed wheels that engage with conveyor chains to drive movement. Conveyor sprockets are available in multiple configurations, such as single, double, and even quintuple formats, to suit various operational needs. Key specifications for these sprockets include the number of teeth, bore diameter, hub diameter, outside diameter, whether they have a hub on one or both sides, length-through bore, and overall weight.
Key Structural Components of Conveyor Sprockets
Sprocket Teeth
he teeth on a sprocket are designed to engage directly with the conveyor chain bushings or rollers. As the sprocket rotates, the teeth pull the chain along in the direction of rotation. The number of teeth is determined by the sprocket’s outside diameter (OD). Notably, choosing an odd number of teeth can help extend the sprocket’s service life, as it prevents the same chain rollers from continuously contacting the same tooth, distributing wear more evenly.
Bore
Most conveyor sprockets come “Bored to Size,” meaning they are pre-machined to fit a specific shaft diameter and include a keyway for secure mounting. This setup facilitates easy assembly and disassembly, especially when paired with Taper Lock clamping sets, which allow for straightforward attachment and removal.
Hub
The hub diameter is a crucial dimension for sprocket stability, as it represents the width across the hub, from one side to the other. The hub size must be balanced to ensure adequate strength while accommodating the keyway and set screws. Importantly, the hub diameter should not exceed the pitch circle diameter minus the conveyor chain’s plate height to prevent chain lifting from the sprocket teeth, which could affect power transmission. Hubs can be placed on one or both sides of a sprocket and vary in diameter depending on the application requirements.
Pitch Circle Diameter (PCD)
The Pitch Circle Diameter (PCD) is an essential measurement as it defines the circle that the chain pins follow when the sprocket rotates. Ensuring correct PCD dimensions is vital for proper chain meshing, which optimizes load distribution and prevents slippage.
Tooth Flank
The tooth flank is the portion of each tooth that directly contacts the conveyor chain’s bush or roller, bearing the brunt of wear. High-quality materials and a precise tooth profile are critical in this area to ensure durability and consistent performance.
Standards for Conveyor Chain Sprockets
While no single international standard exists solely for conveyor chain sprockets, several relevant standards address conveyor chain and sprocket dimensions, ensuring efficient load transmission and compatibility across components. Here is an overview of some key standards:
| Standard | Title | Scope |
|---|---|---|
| ISO 1977:2006 | Conveyor chains, attachments, and sprockets | General conveyor chains and sprockets |
| ISO 1275:2006 | Double-pitch precision roller chains, attachments, and sprockets | Suitable for double-pitch conveyor chain systems |
| ISO 6971:2002 | Cranked-link drag chains of welded construction, attachments, and sprockets | Cranked-link drag conveyor chains |
| ISO 6973:1986 | Drop-forged rivetless chains for conveyors | Used for rivetless conveyor chain systems |
| BS 4116-4:1992 | British series conveyor chains and attachments | British-standard chains and attachments |
| DIN 8165-1:1992 | Solid Bearing Pin Type FV Conveyor Chains | German standard for solid pin type conveyor chains |
| ASME B29.10M-1997 | Heavy Duty Offset Sidebar Power Transmission Roller Chains and Sprockets | Heavy-duty power transmission chains |
Recognizing Sprocket Wear and Planning Replacement
Timely replacement of worn conveyor sprockets is crucial for maintaining efficiency and minimizing additional chain wear. Excessive wear on sprocket teeth can significantly impact conveyor chain longevity, leading to increased maintenance costs. However, premature replacement can also incur unnecessary expenses.
To assess the wear level, inspect the sprocket tooth faces for visible signs of damage or irregularities. When replacement is necessary, proper alignment with the shaft is essential to prevent accelerated wear on the conveyor chain. Misaligned sprockets lead to uneven load distribution, causing strain on the chain and reducing its lifespan.
Alignment Procedure
To ensure proper alignment, use tools such as a straight edge, nylon line, or laser sight across the machined faces of the sprockets. This step verifies that there is no wobble in the alignment. Once alignment is confirmed, ensure that the keys are fully driven home to secure the sprocket in place, providing a stable and reliable setup.
Summary
Conveyor chain sprockets play a fundamental role in the power transmission and efficiency of conveyor systems. Understanding each component’s purpose—from teeth profile to hub specifications—and adhering to relevant standards ensures durability, precise performance, and optimal compatibility within a conveyor chain system. Regular maintenance and timely replacement contribute to reducing downtime and achieving consistent operational efficiency.

Frequently Asked Question
Popular questions about Adjustable Cam Sprocket
A sprocket is a wheel with teeth that engages with a conveyor chain, transferring power and motion in conveyor systems.
Consider teeth count, bore size, material, and hub style based on power, speed, load, and operating conditions.
Common materials include stainless steel, hardened steel, and plastic, chosen for durability, corrosion resistance, or noise reduction.
Measure the pitch circle diameter (PCD), bore diameter, teeth count, and hub dimensions to ensure compatibility.
Replace when teeth show wear or chain tension issues arise; usually every 2–3 years in heavy use or during scheduled maintenance.
Sprocket wear is primarily due to misalignment, heavy loads, poor lubrication, and abrasive environmental conditions.
Larger sprockets increase speed but reduce torque; smaller ones decrease speed while boosting torque, affecting chain efficiency.
Pitch is the distance between chain pins on the conveyor chain that matches the teeth spacing on the sprocket.
Minor wear can be managed temporarily, but for long-term reliability, replacing a worn sprocket is recommended.
Odd-tooth sprockets distribute wear more evenly as each tooth contacts different rollers, extending sprocket life.
