Product Introduction
This is a heavy‑duty double‑row sprocket with integrated hub, generally made of 45# carbon steel with hardened teeth. Matched with double‑row roller chain, it is widely fitted on combine harvesters, seed drills, straw crushers, silage harvesters and other agricultural equipment.
Key Functions on Agricultural Machinery
Power Transmission It transmits torque from engines or gearboxes to working assemblies including cutter headers, augers, reel wheels and seed metering units. The double‑row tooth design delivers higher load capacity, resisting tooth breakage and chain slipping under heavy‑load and bumpy farm‑field conditions.
Speed Adjustment via Transmission Ratio Sprockets of different teeth quantities change the transmission ratio to regulate operating speed. Operators can adjust the speed of crop conveying or seed discharging to fit different crop varieties and working conditions.
Reliable Mounting & Axial Positioning The thickened hub enables direct shaft mounting with keyway fastening. The shoulder structure provides axial limit to avoid chain deviation and derailment, suitable for high‑vibration farm‑working environments.
Shock‑resistance for Harsh Farm Conditions Farms feature heavy dust, straw residues and frequent impact loads. Compared with gear drives, chain‑sprocket drive offers better tolerance to dirt and debris. It provides certain buffer effect under sudden overload to protect core machine components.
Typical Application Scenarios
Combine harvesters: header conveying, grain auger and elevator drive
Seed planters: drive for seed metering shafts to control seeding frequency
Straw returners & crushers: power transfer for cutter shafts
Silage harvesters: material feeding and conveying mechanism drive.
Working‑Condition Requirements
Hardened tooth surface for anti‑wear performance against sand and mud
Double‑row structure for heavy‑load anti‑jump‑tooth performance
Keyway bore for stable installation against continuous mechanical vibration
