Chain sprocket wheel

helical-toothedsplitmetal

Product Overview
Bucket Elevator Sprocket is a high-precision, wear-resistant component designed for material conveying in various industries such as mining, cement, power, ports, chemicals, and grain. Manufactured by Hansheng Automation, this sprocket features ±0.005mm machining accuracy, superior wear and impact resistance, and supports comprehensive customization for different application needs.

Product Features

• μm-level precision: Inner bore, keyway, and mating surfaces are machined to ±0.005mm, ensuring perfect concentricity with the drive shaft, eliminating destructive vibrations, and extending the service life of reducers, bearings, and chains.
• Superior wear & impact resistance: Made from high-strength, wear-resistant alloy steels with computer-controlled tooth surface heat treatment, resulting in a structure that is hard on the outside and tough on the inside.
• Comprehensive customization: Available as standard drive sprockets, tail sprockets, or split/segmented sprockets for easy maintenance. Custom production based on drawings and samples ensures 100% compatibility with your equipment.

Manufacturing Process

• Engineering Consultation and Solution Design: Engineers assess your equipment, materials, and environment to recommend optimal solutions.
• Precision Casting: Advanced lost foam or sand casting with ±0.03mm tolerance ensures dense internal structure and excellent mechanical properties.
• CNC Precision Machining: Large horizontal machining centers (up to 2100mm) ensure all critical dimensions meet or exceed requirements.
• Controlled Heat Treatment: Induction hardening or quenching/tempering for excellent wear resistance and fatigue strength.
• Coordinate Measuring and Measurement (CMM) Quality Inspection: Rigorous dimensional and geometric tolerance inspection for flawless delivery.

Application Areas

• Building Materials Industry: Cement plants, concrete mixing plants (conveying clinker, limestone, sand/gravel)
• Mining Industry: Metal and non-metal mines (hoisting ore and concentrate)
• Power Industry: Thermal power plants (conveying coal and fly ash)
• Ports and Terminals: Bulk cargo terminals (loading/unloading grain, ore, fertilizer)
• Chemical Industry: Fertilizer and chemical plants (conveying chemical raw materials)
• Grain Industry: Grain silos, feed mills (vertical hoisting of grains and feed)

FAQ Highlights

• Pricing reflects higher initial cost but lower total cost of ownership due to extended service life and reduced downtime.
• Split sprockets are as strong and rigid as integral sprockets, with easier replacement and maintenance.
• Typical production cycle for standard products is 15 working days, with delivery time depending on size and complexity.
