Conveyor Chain Sprocket

Conveyor Chain Sprocket performance depends on maintaining precise alignment with the chain drive axis. Deviation in radial or axial alignment causes eccentric chain loading, resulting in asymmetric tooth wear and chain pitch elongation. Each Conveyor Chain Sprocket is CNC-machined with controlled runout and concentricity tolerances typically below 0.03 mm to prevent misalignment-driven mechanical degradation.

Product Description

Sprocket teeth in Conveyor Chain Sprockets are subjected to repetitive contact stress and cyclic loading from chain rollers. To resist micro-pitting and fatigue crack propagation, hardened tooth flanks are produced using induction hardening processes achieving surface hardness of 58–62 HRC with core ductility maintained above 25% elongation. This material gradient resists both surface wear and core deformation during high-cycle operation. 

Material Specification

Carbon Steel (AISI 1045, C45), Stainless Steel (SS 304, SS 316), Cast Iron (Grade 25, 35)

Hardness (Heat Treatment)

45-55 HRC (Hardened teeth for wear resistance)

Outside Diameter (OD)

Calculated based on teeth & pitch

Hub Diameter & Length

Hub Diameter – 1.2× Bore; Hub Length – 1.5× Bore (Customizable for heavy-duty applications)

Certification Standard

ANSI B29.1, ISO 606, DIN 8187, JIS B 1801

Technical Advantages

Proper interaction between chain rollers and Conveyor Chain Sprocket teeth reduces contact shock and minimizes load concentration. Tooth profiles are generated using involute geometry with full flank radius to promote gradual roller seating and controlled disengagement. This design minimizes stress risers and ensures uniform load transfer across the chain-sprocket interface, extending operational life of both components. 

Conveyor Chain Sprockets used in high-humidity or chemical exposure zones often fail due to surface oxidation or crevice corrosion. Selection of material grades such as AISI 420 or 316L stainless steel, or application-specific coatings like zinc-nickel, PTFE composite, or electroless nickel plating, ensures corrosion resistance. These treatments prevent material loss, galling, and fatigue degradation in Conveyor Chain Sprockets.

Industry Applications

Automotive Assembly Lines

Synchronizes chain-driven pallet conveyors for precise body transport, ensuring alignment and speed consistency across multiple robotic workstations. 

Steel and Metallurgical Plants

Drives heavy-duty roller chains under extreme loads and high temperatures in billet handling, cooling beds, and furnace feed systems. 

Cement Manufacturing Units

Transfers clinker and raw material via drag chain conveyors; sprockets resist abrasion from highly alkaline and dusty environments. 

Food and Beverage Processing

Operates stainless steel chain conveyors in washdown zones, requiring corrosion-resistant sprockets with hygienic tooth geometries and sealed bore interfaces. 

Pharmaceutical Packaging Systems

Powers precision indexing conveyors with fine-pitch chain sprockets for blister pack handling, ensuring dosage alignment and minimal vibration transmission. 

Mining and Bulk Material Handling

Engages high-tensile chains in scraper conveyors for ore and coal transfer under abrasive, shock-loaded, and high-humidity underground conditions. 

 

Conveyor Chain Sprocket

Dimensional Repeatability for Multi-Drive Systems

Multiple Conveyor Chain Sprockets operating in parallel require dimensional uniformity to prevent asynchronous chain travel and excessive strain on drive elements. All sprockets undergo coordinate measuring machine (CMM) validation for pitch accuracy, bore tolerance (H7 or custom as specified), and tooth indexing within micrometer-grade limits. Such precision ensures consistent meshing behavior across interconnected shafts. 

Applications with frequent stop-start cycles expose Conveyor Chain Sprockets to sudden torque spikes. High-toughness alloy steels with tempered martensitic microstructures are used to absorb dynamic forces without tooth chipping or hub fracture. Sprockets are verified for impact toughness (Charpy V-Notch > 20J at room temperature) and rotational fatigue using finite element simulation models under cyclic torque conditions. 

 

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure pitch accuracy in Conveyor Chain Sprocket manufacturing?

Frigate uses precision CNC machining and digital pitch measuring tools to maintain pitch error below ±0.05 mm. Each sprocket is validated using coordinate measuring machines (CMM) to ensure uniform tooth spacing. Accurate pitch alignment is critical for consistent roller engagement and chain tension control. This reduces vibration and extends both chain and sprocket life. 

What surface treatments does Frigate offer for Conveyor Chain Sprockets exposed to corrosive media?

Frigate applies treatments such as black oxide, electroless nickel plating, or zinc-nickel alloy coatings based on environmental conditions. These coatings provide barrier protection against oxidation, pitting, and chemical attack. Coating thickness and adhesion are tested per ASTM B117 and ISO 9227. This ensures long-term surface stability in corrosive or washdown applications. 

How does Frigate design Conveyor Chain Sprockets for high torque and intermittent shock loading?

Frigate selects high-toughness alloy steels like EN24 or 4340 with heat treatment tailored to achieve high surface hardness and ductile core. Tooth geometry is optimized to reduce stress concentrations under dynamic load. Fatigue simulations and FEA are used during design to evaluate torque distribution and failure zones. This approach enhances sprocket performance under cyclic impact. 

 

Can Frigate supply Conveyor Chain Sprockets with non-standard bore geometries and tolerances?

Frigate provides custom bore configurations including taper bore, spline bore, and interference-fit bores as per ISO H7, H6, or special class fits. Bore alignment is ensured using jig-based inspection during finishing. Keyways and retaining features are machined to ISO 773 and DIN 6885 standards. These customizations ensure precise fitment on all shaft types. 

 

How does Frigate handle Conveyor Chain Sprocket production for synchronized multi-shaft conveyors?

Frigate manufactures matched sprockets using identical machining programs and batch heat-treatment to ensure dimensional uniformity. Tooth indexing is verified to ensure synchronization across shafts. This avoids chain misalignment, uneven wear, and phase lag in parallel drive systems. Consistency across sprockets ensures stable multi-chain load distribution in synchronized conveyors.
