company news about PU Round Belts Performance in Power Transmission Explained

In the precision-driven world of modern industry, mechanical power transmission plays a pivotal role. If engines are the heart of industrial operations, transmission belts serve as the vital veins connecting this heart to critical components. Among the various belt materials available, polyurethane (PU) round belts stand out for their exceptional performance. Compared to traditional leather or rubber belts, PU round belts offer superior wear resistance, longer service life, enhanced anti-slip properties, and easier maintenance. For instance, in textile workshops, outdated leather round belts often slip, reducing productivity. Switching to PU round belts not only eliminates slippage but also significantly extends replacement cycles, lowering operational costs.

PU round belts can be categorized into two types based on surface characteristics: smooth and rough surfaces. Each type excels in specific performance metrics and applications. This article provides an in-depth analysis of smooth and rough surface PU transmission belts, offering detailed application guidelines to help users make informed choices that enhance equipment efficiency and longevity.

Smooth surface PU round belts, as the name suggests, feature a flat, polished surface with a fine texture. This characteristic grants them unique advantages, making them ideal for specific applications.

• Easy Cleaning: The smooth surface resists dirt accumulation, and any minor contaminants can be effortlessly wiped away, ensuring hygienic transmission processes.
• High Elasticity: Excellent elasticity allows these belts to adapt to complex mechanical transmission systems, maintaining stable performance even under high-speed operation or frequent start-stop cycles.
• High Strength: Outstanding tear and tensile strength enable them to withstand significant tension and impact without breaking or deforming.
• Chemical Resistance: Resistant to various chemicals and oils, ensuring stable performance even in harsh environments.
• Wear Resistance: The surface exhibits superior wear resistance, minimizing aging or degradation over extended use.
• Low Noise: Operates quietly, making it suitable for noise-sensitive environments such as offices, laboratories, or food processing facilities.

• Light to Medium Load Transmission: Ideal for conveying lightweight or medium-weight materials like agricultural products, fruits, vegetables, and newspapers.
• Food and Packaging Industry: The easy-to-clean surface makes these belts perfect for food processing and packaging equipment, preventing bacterial growth and ensuring food safety.
• Textile and Printing Machinery: Their elasticity and wear resistance make them well-suited for textile and printing machines, where they endure high-speed operation and frequent start-stop cycles.

Unlike their smooth counterparts, rough surface PU round belts feature textured or uneven surfaces. This design enhances friction, making them ideal for heavy-load transmission and long-distance conveying.

• High Friction: The rough surface significantly increases the coefficient of friction, improving grip and preventing material slippage or drops during transmission.
• Robust Physical Properties: Retains high elasticity, tear resistance, chemical resistance, and oil resistance, ensuring reliable performance in demanding conditions.
• Medium-Load Transmission: Capable of handling heavier materials, such as construction supplies, metal products, or large equipment.

• Medium-Load Transmission: Suitable for systems requiring higher load-bearing capacity, such as logistics centers transporting packages or cartons.
• Long-Distance Conveying: Excellent wear resistance makes these belts ideal for long-haul applications, such as mining or port operations involving bulk materials like ore or coal.
• Industrial Equipment: Widely used in packaging machinery, canning lines, textile machines, paperboard processing plants, and agricultural transport systems, where they deliver reliable power transmission.

PU round belts are typically joined using thermal fusion, a simple and cost-effective method for on-site installation and maintenance.

1. Heating: Preheat the heating plate of the PU belt connector to the appropriate temperature.
2. Cutting: Cut the PU belt to the desired length, ensuring a clean edge.
3. Welding: Press both ends of the belt onto the heating plate until melted, then quickly join them under pressure until cooled.
4. Trimming: Use diagonal pliers to smooth the joint, ensuring seamless transmission.

Although thermal-fused PU belts have joints, their no-mold requirement and extended lifespan make them more cost-effective than seamless O-ring belts, solidifying their status as an industrial staple.

Smooth and rough surface PU round belts each excel in specific scenarios. Smooth belts are optimal for light-load, clean environments, while rough belts are better suited for medium-load, long-distance applications. Consider the following factors when selecting:

• Load Capacity: Choose smooth belts for lighter materials and rough belts for heavier loads.
• Transmission Distance: Rough belts are preferable for long-distance conveying due to their wear resistance.
• Operating Environment: For humid or oily conditions, prioritize belts with chemical and oil resistance.
• Hygiene Requirements: Smooth belts are easier to clean, making them ideal for food, pharmaceutical, and other hygiene-sensitive industries.

By understanding application requirements, selecting the appropriate diameter, and mastering connection techniques, users can tailor PU round belts to their needs, achieving efficient and durable mechanical power transmission.

Beyond the applications mentioned, PU transmission belts are also widely used in textile machinery, printing equipment, food processing lines, ceramic production, glass manufacturing, and tile production—any industrial setting requiring reliable mechanical power transmission. A thorough understanding of smooth and rough surface PU round belts empowers users to optimize equipment performance and longevity.
