STEEL CORD CONVEYOR BELT

 

Usage

Steel cord conveyor belts are suitable for high strength, long distance, and heavy load transportation of materials, which are widely used in coalmines, mines, ports, metallurgy, electricity, chemical industries, etc.

 

Characteristics

1. High tensile strength: The belts are suitable for large span, long distance transportation of materials.

2. Small elongation in use: The belts need only a very short take-up stroke distance.

3. Small diameter of drive pulley: The carcass has a layer of longitudinally arranged steel cords as its skeleton,and thus is resistant to flex fatigue. Therefore, drive pulley of smaller diameter can be used to make the equipment smaller.

4. High adhesion between rubber and steel cord: The steel cords are coated with zinc on their surface, and also the rubber used has the property of good adhesion with steel cords. Therefore, the rubber is tightly adhered to the steel cords and is resistant to shock and difficult to drop, so the rubber belts are long in service life.

5. Even tension of steel cords: Out of our advanced techniques in manufacturing, the steel cords are very evenly arranged and have the same tension, so the belts are well balanced in running and difficult to run deviation.

6. Good troughability: As the carcass has no transverse skeleton, it is easy to form a deep trough, so the belts can load more materials and prevent the materials from escaping.

7. Good troughability: As the belt body has no transverse skeleton, it is easy to from a deep trough, so the belts can load more materials and prevent the materials from escaping.

8. Inspection of the belt with X-rays: Users can take X-rays to inspect damages of the skeleton steel cords on the conveyor machines to prevent accidents from happening.

Are there any specific guidelines for aligning pulleys and V-belts?

Proper alignment between pulleys and V-belts is essential to ensure smooth operation, minimize wear, and maximize the efficiency of the belt drive system. Here are some specific guidelines for aligning pulleys and V-belts:

  1. Parallel Alignment:
  2. The pulleys should be aligned parallel to each other, meaning that the axes of the pulleys should be in the same plane. This ensures that the V-belt runs straight and evenly between the pulleys. Misalignment can cause the belt to run at an angle, leading to increased wear and reduced efficiency.

  3. Angular Alignment:
  4. In addition to parallel alignment, the pulleys should be aligned angularly. This means that the pulley faces should be perpendicular to the belt’s direction of travel. Angular misalignment can cause the belt to twist and create uneven tension, resulting in increased wear and potential belt failure.

  5. Alignment Tools:
  6. To achieve proper alignment, various alignment tools can be used, such as straightedges, laser alignment tools, or alignment software. These tools help in measuring and adjusting the alignment of pulleys, ensuring precise parallel and angular alignment.

  7. Adjustment Methods:
  8. To adjust the alignment of pulleys, different methods can be employed. Common adjustment methods include shimming, moving the pulley on its shaft, or using adjustable pulleys. The specific method depends on the type of pulley and the adjustment capabilities of the system.

  9. Regular Inspections:
  10. Regular inspections are crucial to identify and correct any misalignment issues promptly. Inspect the pulleys visually and check for any signs of misalignment, such as uneven belt wear, belt tracking issues, or abnormal belt noise. If misalignment is detected, take corrective measures to realign the pulleys.

  11. Manufacturer Recommendations:
  12. Always refer to the manufacturer’s guidelines and specifications for pulley alignment. Manufacturers often provide specific alignment tolerances and recommendations for their products, considering factors such as belt type, load, and operating conditions. Follow these recommendations to ensure proper alignment and optimize the performance of the belt drive system.

By following these guidelines for aligning pulleys and V-belts, you can minimize wear, reduce the risk of belt failure, and maximize the efficiency and lifespan of the belt drive system.

Can V-belts be used in high-speed or heavy-duty applications?

V-belts are versatile power transmission belts that can be used in a wide range of applications, including high-speed and heavy-duty applications, depending on the specific design, construction, and material of the V-belt. Here’s a detailed explanation:

High-speed applications:

V-belts are capable of transmitting power efficiently at various speeds. However, the speed limitations of V-belts depend on factors such as the belt’s design, material, and construction. Traditional V-belts, also known as classical V-belts, are generally suitable for moderate to high-speed applications but may have limitations at extremely high speeds due to centrifugal forces and heat generation.

For high-speed applications, specialized V-belt designs, such as high-speed V-belts or narrow V-belts, are available. These belts are designed to reduce heat buildup and minimize the effects of centrifugal forces, allowing them to operate effectively at higher speeds. It is important to consult the manufacturer’s specifications and recommendations to select the appropriate V-belt for high-speed applications.

Heavy-duty applications:

V-belts can also be used in heavy-duty applications that require the transmission of high torque or power. Heavy-duty V-belts, also known as industrial or agricultural V-belts, are specifically designed to handle heavy loads and provide reliable power transmission in demanding conditions.

Heavy-duty V-belts are constructed using reinforced materials, such as strong fabric layers or aramid cords, to enhance strength and durability. These belts are designed to resist stretching, withstand high loads, and operate in environments with high temperatures, humidity, or exposure to chemicals.

In addition to heavy-duty V-belts, there are other belt options available for heavy-duty applications, such as cogged V-belts and synchronous belts. These belts feature specialized designs and toothed profiles that offer increased power transmission capabilities, improved grip, and enhanced resistance to slip.

When considering the use of V-belts in high-speed or heavy-duty applications, it is crucial to consult the manufacturer’s specifications, guidelines, and application recommendations. The manufacturer can provide information on the suitable V-belt types, sizes, and materials that can withstand the specific demands of the application.

Overall, V-belts can be used effectively in high-speed and heavy-duty applications, provided the appropriate type, design, and construction are selected based on the application requirements and manufacturer’s recommendations.

What are the signs of a worn or damaged V-belt that needs replacement?

A worn or damaged V-belt can lead to decreased performance, increased energy consumption, and potential equipment failure. Recognizing the signs of a worn or damaged V-belt is important for timely replacement and preventing further damage. Here are some common signs to look out for:

  1. Visible wear: Inspect the V-belt for visible signs of wear, such as fraying, cracking, or glazing. Excessive wear indicates that the belt has reached the end of its service life and should be replaced.
  2. Chunking or missing pieces: If the V-belt shows signs of chunking or has missing pieces, it is a clear indication of severe damage. This can occur due to excessive tension, overloading, or prolonged use beyond the belt’s capacity.
  3. Excessive noise: A worn or damaged V-belt may produce noticeable noise during operation. This can be in the form of squealing, screeching, or rumbling sounds. The noise is often caused by slipping, misalignment, or belt degradation.
  4. Slippage: If the V-belt slips on the pulleys, resulting in reduced power transmission or inconsistent operation, it indicates a problem. Slippage can occur due to incorrect tension, pulley misalignment, or insufficient grip caused by belt wear.
  5. High heat or burning smell: Excessive heat generated by a V-belt can indicate friction caused by belt slippage or misalignment. If you notice a burning smell or feel excessive heat near the belt drive system, it is a sign of potential belt damage.
  6. Loss of tension: If the V-belt consistently loses tension and requires frequent readjustment, it indicates wear or elongation. Over time, the belt may stretch and lose its original tension, resulting in reduced power transmission efficiency.
  7. Reduced power transmission: A worn or damaged V-belt may struggle to transmit the required power, leading to decreased equipment performance. This can result in slower operation, reduced torque, or inability to handle the load.
  8. Visible cracks or separation: Cracks or separation in the V-belt’s rubber material are clear signs of damage. These can occur due to age, exposure to harsh environments, or chemical degradation. Cracked or separated belts should be replaced immediately.
  9. Shortened belt life: If a V-belt consistently fails or requires replacement sooner than its expected service life, it indicates a problem. Factors such as incorrect tensioning, misalignment, or excessive load can contribute to premature belt failure.

If you observe any of these signs in a V-belt, it is recommended to replace the belt promptly. Continuing to use a worn or damaged V-belt can lead to further damage, increased downtime, and potential equipment failure. Regular maintenance and inspections are essential for identifying and addressing these signs early, ensuring the reliability and longevity of the V-belt system.
