Technical Parameters
Crafted from high-strength cast steel or alloy steel, this harvester sprocket features a rugged wheel body that withstands high-intensity harvesting operations. Many models undergo surface quenching or overall quenching and tempering treatment, enhancing wear resistance and extending service life. The sprocket’s teeth are precision-machined to ensure tight meshing with conveyor chains, reducing slippage and minimizing wear on both the sprocket and chain. It includes strategically placed installation holes or splines for secure connection to the harvester’s main shaft or transmission shaft, ensuring reliable torque transmission. Some models feature a protective structure—such as blocking edges or reinforcement rings—to prevent the chain from falling off during operation. The sprocket’s compact design allows for easy integration into the harvester’s existing transmission system, with compatibility across multiple World Harvester models.

Product Uses
Installed in the cutting table conveyor systems of combine harvesters, this driving chain wheel powers conveyor chains. It ensures crops are smoothly transported from the cutting area to the threshing mechanism, preventing jams and improving harvesting speed.
Ideal for use in harvester lifting chain mechanisms, the sprocket drives the chain to lift crops from the ground to the processing components. It supports consistent lifting performance, even with heavy crop loads.
In the harvester’s cleaning system, this transmission sprocket powers the chain that drives vibrating screens and other cleaning components. It ensures the cleaning system operates at the correct speed, enhancing impurity removal efficiency.
Specifically designed for World Harvesters, this driving chain wheel is a direct replacement for original parts. It fits seamlessly into the harvester’s transmission system, eliminating the need for modifications or adjustments.
Built for heavy-duty use, this sprocket performs reliably in high-volume harvesting operations. It resists wear and deformation, even when exposed to continuous use in challenging field conditions.
Product Operate Guide
Before installing the driving chain wheel, inspect the sprocket for any signs of damage, such as worn teeth, cracks, or deformities. Check the harvester’s transmission shaft and mounting points to ensure they are clean and free of debris. Verify that the chain is in good condition, with no signs of excessive wear or stretching.
Align the driving chain wheel with the transmission shaft, ensuring the installation holes or splines fit securely. Tighten the mounting bolts to the recommended torque, ensuring a stable connection that prevents slipping during operation. Adjust the chain tension to the optimal level—neither too loose nor too tight—to prevent accelerated wear on the sprocket and chain.
During harvesting, maintain a consistent operating speed to avoid sudden stress on the driving chain wheel and chain. Avoid overloading the harvester with excessive crop volumes, which can strain the transmission system. Regularly monitor the sprocket and chain during operation, checking for signs of misalignment or unusual noise.
Clean the driving chain wheel regularly to remove soil, dust, and crop residues. Use a brush or compressed air to clear debris from the teeth and mounting area, preventing buildup that can cause friction or jamming. Inspect the sprocket’s teeth for wear during each maintenance cycle—replace the sprocket if teeth become sharpened, uneven, or missing. For optimal performance, replace the sprocket and chain as a set, ensuring proper meshing and extending the lifespan of both components. Store spare agricultural sprockets in a dry, protected environment to prevent corrosion and damage.
