Product Description

Product Description

Production DescriptionThe illustrated sprocket is made of high-quality alloy steel, with the surface quenched to achieve a tooth surface hardness of HRC58-62, providing excellent wear resistance; the wheel body features a ventilation hole design, which ensures strength while effectively reducing weight and facilitating heat dissipation; the central hole has a keyway and connects to the shaft via a flat key, ensuring efficient and reliable torque transmission. The product precision complies with the GB/T 1243-2006 "Roller Sprocket" standard, operating smoothly with low noise, suitable for continuous long-term operation.

Product FunctionsPower Transmission: The sprocket engages with the chain to transmit power from the drive unit to the conveying or working mechanism, enabling continuous equipment operation.Precise Transmission Ratio: The number of sprocket teeth combined with the chain pitch ensures an accurate and stable transmission ratio without slip loss.Heavy Load Capacity: The sprocket teeth are strengthened through heat treatment, enabling them to withstand high tension and impact loads during operation of equipment such as scraper conveyors and stage loaders.Wear and Impact Resistance: Tooth surface hardness can reach HRC 50 to 60, providing good wear resistance and impact toughness to adapt to high-wear and high-impact conditions in underground coal mines.Chain Guidance and Alignment: The precise tooth profile controls the chain's running path, preventing chain disengagement or misalignment and ensuring stable operation of the conveying system.Quick Replacement: Split or tooth ring type sprockets allow replacement of worn tooth rings without removing the entire shaft, reducing downtime and lowering maintenance costs.Overload Protection Function: In certain designs, sprockets can be equipped with shear pins or torque limiters to interrupt power transmission during overload conditions, protecting equipment from damage.Applications

Scraper Conveyor: Sprockets are installed at the head drive unit and tail return unit to drive the scraper chain for coal conveying. Operating conditions feature high tension, high impact, and continuous wear.
Stage Loader: Sprockets drive the scraper chain of the stage loader to transfer coal from the scraper conveyor to the belt conveyor. Operating conditions feature medium loads and frequent starts.
Shearer: Sprockets are used in the shearer traction mechanism, engaging with the rack bar to drive the shearer back and forth along the longwall face. Operating conditions feature high positioning accuracy, bidirectional forces, and dynamic impact.
Feeder Breaker: Sprockets drive the feeder conveyor chain to control material feed rate. Operating conditions feature low speed, high torque, and direct material impact.
Bucket Elevator: Sprockets drive the lifting chain and buckets to achieve vertical material lifting. Operating conditions feature continuous operation and medium loads.
Roadheader: Sprockets are used in the loading mechanism and traction mechanism of roadheaders to drive rakes or tracks. Operating conditions feature intermittent heavy loads and severe vibration.
Belt Conveyor Tensioner: Sprockets are used in manual or automatic tensioning devices for speed reduction transmission to adjust belt tension. Operating conditions feature low speed and intermittent operation.
Mine Hoist Auxiliary Mechanism: Sprockets are used in hoist gate opening/closing mechanisms or limit devices for precise position control. Operating conditions feature low-frequency operation and high positioning requirements.Main Products
