High Load Capacity Polyurethane Coated AGV Drive Wheels

Polyurethane Coated AGV Drive Wheels are high-performance traveling components specifically designed for Automated Guided Vehicles (AGVs). Through material innovation and structural design, they significantly enhance the operational efficiency, stability, and maintenance convenience of AGVs in industrial scenarios. The following analysis covers four core aspects: key advantages, structural features, application scenarios, and technical parameters.

I. Key Advantages: Breakthroughs in Performance and Efficiency

High Load Capacity and Wear Resistance: The polyurethane coating offers a hardness range of Shore A 75-90, providing a load-bearing capacity 7 times that of natural rubber and 3-5 times higher wear resistance under the same dimensions. For instance, in automated warehousing environments where AGVs require frequent start-stop operations and steering, polyurethane wheels exhibit a wear rate only 1/5 that of rubber wheels, with a service life exceeding 5 years, significantly reducing downtime for maintenance.

Shock Absorption, Noise Reduction, and Precision Positioning: Polyurethane elastomers absorb over 90% of ground vibrations, resulting in an operational noise level below 55 decibels—meeting the requirements of noise-sensitive environments such as cleanrooms and operating rooms. Additionally, the low rolling resistance characteristic improves AGV positioning accuracy by 30%, ensuring precise navigation in narrow aisles or dense shelving areas.

Chemical Resistance and Antistatic Properties: Polyurethane materials demonstrate strong resistance to chemicals such as engine oil, lubricants, acids, alkalis, and salts, enabling long-term stable operation in industries like food processing and chemical manufacturing. Furthermore, their antistatic performance eliminates frictional sparks, making them suitable for flammable and explosive environments to ensure operational safety.

II. Structural Features: Modular and Reliable Design

Dual-Hardness Composite Layer Structure: The wheel adopts a composite design with an outer layer (Shore A 85-90 for high wear resistance) and an inner layer (Shore A 65-70 for shock absorption and cushioning), balancing grip and operational comfort. For example, in logistics sorting centers, the high-hardness outer layer resists frequent scratches from metal pallet edges, while the low-hardness inner layer cushions the impact force during AGV emergency stops.

Anti-Slip Groove and Wheel Flange Design: The wheel surface features a diamond-shaped closed-groove structure with an optimized drainage angle of 135°, ensuring an anti-slip coefficient ≥ 0.75 on wet and slippery surfaces. The wheel flange maintains close contact with shelf rails, guaranteeing stability during high-speed AGV movement (e.g., 1.5 m/s) and minimizing offset errors.

IV. Application Scenarios: Multi-Industry Adaptability

Medical and Clean Environments: Mobile CT equipment, surgical robots, and other medical devices demand exceptional movement stability. Polyurethane wheels comply with ISO 10993 biocompatibility standards, with no leachables and low odor. Their radiation resistance outperforms rubber, enabling them to withstand X-ray radiation during CT scans and ensuring precise movement of medical equipment.

Extreme Temperature Environments: In cold chain logistics (-25℃ to -40℃) or high-temperature workshops (80℃), polyurethane wheels retain their elasticity and strength, avoiding performance degradation caused by material embrittlement. For instance, in meat processing plants, polyurethane wheels maintain stable traction even in low-temperature conditions.

In summary, Polyurethane Coated Heavy-Duty AGV Drive Wheels have gained widespread application across multiple sectors due to their unique structural characteristics and superior performance advantages. They not only improve equipment operational efficiency and handling capacity but also enhance workplace environments and safety standards.
