Product Characteristics
Precise Transmission Without SlippagePrecision meshing of tooth profile keeps fixed transmission ratio, no slipping or speed loss. Its transmission accuracy is far higher than belt drive.
High Load Capacity for Heavy DutyHigh overall structural strength and wear-resistant teeth can bear large torque and impact load, suitable for heavy industry and continuous working conditions.
High Transmission Efficiency & Low LossMeshing transmission reduces power loss effectively, delivers high efficiency, and runs more energy-saving and stably in long-term operation.
Durable Structure & Long Service LifeTooth surface can be hardened to enhance wear and fatigue resistance. It is not easy to cause tooth breakage or deformation under high-frequency continuous operation.
Easy Installation & Convenient MaintenanceCompact structure with simple alignment installation. No frequent lubrication required; only daily inspection of chain wear and tension is needed.
Strong Versatility & Good InterchangeabilityManufactured in accordance with national and European standards with standardized pitch, tooth quantity and inner bore size. Products of the same specification can be directly replaced.
Wide Application RangeCompatible with various standard chains, applicable for low speed, medium & high speed, heavy load and dusty working conditions.
Material：
1. Gray Cast Iron HT200/HT250 (Economical General Type)
Features: Moderate hardness, easy casting and machining, good shock absorption, not easy to deform.Advantages: Low price, high cost performance, low operating noise, suitable for mass production.Application: Ordinary conveyors, agricultural machinery, fans and light industrial general machinery for light-load and low-speed scenarios.Notes: Poor toughness and weak impact resistance, not suitable for high speed and heavy load; prone to rust in humid environments.
2. Ductile Iron QT500/QT600 (High-Strength Heavy-Duty Type)
Features: Much better toughness, tensile strength and impact resistance than ordinary gray cast iron, wear-resistant and hard to break teeth.Advantages: Vibration-proof, impact-resistant and high load-bearing capacity, stable and durable under heavy-load operation.Application: Mining machinery, crushers, heavy-duty conveyors and heavy equipment with frequent start and stop.Notes: Higher cost than ordinary cast iron; aging treatment is required to prevent processing deformation.
3. 45# Carbon Steel (Medium & Heavy-Duty Precision Turning Type)
Features: High strength and good toughness; tooth quenching is available to improve hardness and wear resistance with high precision.Advantages: Not easy to deform, strong load capacity, wear-resistant and durable, suitable for medium-high speed and medium-heavy load transmission.Application: Machine tools, printing & packaging machinery, medium assembly lines and industrial transmission equipment.Notes: Easy to rust without surface treatment; galvanizing, blackening or anti-rust oil treatment is necessary.
4. Alloy Structural Steel 40Cr/20CrMnTi (High-End Heavy-Duty Type)
Features: Extremely high hardness, wear resistance, impact resistance and fatigue resistance after carburizing and quenching.Advantages: Ultra-large torque bearing capacity, no tooth breakage or abrasion under high speed and heavy load, with the longest service life.Application: Large metallurgical and mining equipment, high-speed precision transmission and extreme heavy-duty working conditions.Notes: High cost, difficult processing, requires professional heat treatment.
5. Stainless Steel 304/316 (Anti-Corrosion Special Type)
Features: Rust-proof, acid and alkali resistant, high sanitary grade, adaptable to humid, watery and seaside environments.Advantages: Lifetime rust-proof, no frequent maintenance required, meeting both sanitary and anti-corrosion demands.Application: Food machinery, medical equipment, chemical industry, water treatment and seaside outdoor equipment.Notes: Moderate hardness and limited load capacity, only suitable for light and medium load.
6. Aluminum Alloy 6061/6063 (Lightweight High-Speed Type)
Features: Light weight, low inertia, high machining precision, available for anodizing anti-corrosion treatment.Advantages: Sensitive start-up, stable high-speed operation, exquisite appearance and good oxidation resistance.Application: Small automation equipment, light industry machinery and high-speed light-load transmission scenarios.
FAQ:
Q: Why can't sprockets of the same model mesh interchangeably with standard chains?
A: ① Not produced in accordance with national/European standards, with deviations in pitch and tooth thickness; ② Offset keyway position leading to tooth misalignment after installation; ③ Excessive machining dimensions of addendum circle and dedendum circle.
Q: Why does the sprocket easily jump teeth or derail during use?
A: ① Severe tooth wear and sharpened addendum leading to insufficient friction; ② Excessive chain stretching and increased pitch; ③ Overload beyond the sprocket's load capacity; ④ Eccentric installation of two sprockets leading to transmission deviation.
Q: How to avoid cast iron sprockets from breaking teeth and chipping edges?
A: ① Select qualified gray cast iron/ductile iron and do aging treatment to release internal stress; ② Avoid heavy load impact and frequent start-stop; ③ Regularly check tooth wear and replace in time.
