Company Profile




1. Avoid the idler being covered by the material, causing the rotation to be ineffective, prevent the leakage of the material from being stuck between the roller and conveyor belt, and pay attention to the lubrication of the moving part of the conveyor belt, but do not contaminate the rubber conveyor belt;

2. Prevent rubber conveyor belt load from starting;

3. If the rubber conveyor belt deviates, measures should be taken to correct it in time;

4. When the rubber conveyor belt is found to be damaged locally, repair materials in time to avoid expansion;
5. Prevent the rubber conveyor belt from being blocked by the frame, pillars, or block materials, and prevent it from being broken and torn.


1. Local wear (skin damage)
Fabric-core rubber conveyor belts and steel-core rubber conveyor belts are prone to such damage. The main reason is that the transfer place, the material CZPT trough, the failed idler, and other parts are easily stuck with large material blocks. Once the rubber conveyor belt is running, it will definitely cause excessive wear of the rubber conveyor belt.

2. Partial fragmentation (penetrating injury)
Fabric core rubber conveyor belts and steel core rubber conveyor belts have such damage. When the rubber conveyor belt is transporting materials, there are often larger stones and sharp material blocks mixed in. These material blocks break through the rubber conveyor belt with a large impact force at the transition because of insufficient buffering, forming holes. lf the material is mixed with sharp objects, such as iron crowbars, it is very easy to scratch the rubber conveyor belt, resulting in large-area tearing of the rubber conveyor belt.

3. Damage to the glued part
The adhesive part of the rubber conveyor belt is formed by re-lap vulcanization when the tape is installed. If the joints are not handled properly, it is easy to cause premature wear of the joints, peeling, and other phenomena. If it is not dealt with in time, the damage and deterioration of the joint part will be faster, and the belt breakage accident will easily occur.

4. Longitudinal crack of steel wire rubber conveyor beltSome steel-core rubber conveyor belts often have longitudinal penetrating scratches, which can be as long as tens of meters or even hundreds of meters. Such damages are generally called longitudinal cracks. Most of the reasons are that the sharp object is stuck in some places, such as the scraper cleaner, and the operator does not clean it up in time. After the belt runs, the rubber conveyor belt is scratched and torn over a long distance.


During the use of conveyor belts, there are also many forms of damage, such as edge delamination, festering, defects, and cracks; long-distance longitudinal tears, and deep scratches. noles, large areas of wear, covering rubber drums or peeling, joints internal defects, etc. Among them, the longitudinal tear is the most urgent, the edge damage is the most common inherent defects of the joint are unavoidable, and the service life after repair is the most concerned.
The commonly used repair methods for conveyor belts mainly include the following three

1. Hot repair methods: Usually, special repairers, vulcanizers, and hot vulcanization materials suitable for conveyor belts are used to repair the damaged parts of the conveyor belt with equal strength “no trace”. This kind of repair can completely eliminate the damage to the conveyor belt and restore it to its original state. lt is suitable for more important, long-distance, high-speed, and large-volume transportation systems. Completing this type of maintenance requires specialized equipment and professionals. The hot repair method is the most reliable and ideal method for the maintenance of rubber conveyor belts.

2. Cold repair method: Usually, special cold adhesives, repair films, and special tools for conveyor belts must be used to fill in the damaged parts of the conveyor belt to achieve the purpose of continuous operation. Obviously, this infill repair is a stopgap measure. Therefore, its main purpose is: when the conveyor belt is damaged, timely cold repair can prevent the damaged part of the conveyor belt from continuing to expand and extend, so as to effectively protect the core of the conveyor belt from damage, so as to wait and obtain Time and opportunity for repairs.

3. Mechanical repair method: Usually, clips, nails, connecting plates and screws or metal cords, and special appliances made of metal materials are used to fix or connect the damaged parts of the conveyor belt to achieve the purpose of maintaining operation. Even in many times and on many occasions today, this seemingly simple, rough, and even ugly treatment method can play an emergency function and achieve twice the result with half the


Abrasion-resistant rubber conveyor belts are a widely used conveying device in various industrial settings. its properties such as wear resistance, high-temperature resistance, and tensile strength play an important role in industrial production.

First of all, the wear-resistant rubber conveyor belt has excellent wear resistance, and its surface cover is made of special materials with excellent wear resistance. In industrial production, it is often necessary to transport large quantities of hard materials such as ore, coal, sand, and gravel, and these materials are very CZPT to the conveyor belt. If ordinary conveyor belts are used, they will wear out quickly and need to be replaced frequently, whereas with wear-resistant rubber conveyor belts, the service life can be significantly extended and production costs reduced.

Secondly, wear-resistant rubber conveyor belts also have good resistance to high temperatures. In industrial production, many materials need to be transported at high temperatures. Ordinary conveyor belts cannot withstand the corrosion and thermal expansion of high-temperature environments and are prone to aging and cracking. Wear-resistant rubber conveyor belts are made of special materials that can withstand high temperatures and maintain good performance to ensure a smooth conveying process

In addition, the tensile strength of wear-resistant rubber conveyor belts is also very good. industrial production, conveyor belts need to withstand huge tensile forces, and if the tensile strength is not sufficient, the belt is prone to breakage and breakage, affecting productivity. The high strength of wear-resistant rubber conveyor belts, on the other hand, enables them to withstand large amounts of tensile force, ensuring the safety and reliability of the conveying process.

To sum up, wear-resistant rubber conveyor belts have important applications in industrial production. its excellent wear resistance, high-temperature resistance, and tensile strength can effectively improve production efficiency and reduce production costs, bringing many benefits to industrial production.

What are the key differences between standard V-belts and cogged V-belts?

Standard V-belts and cogged V-belts are two variations of V-belts that differ in their design and performance characteristics. Here are the key differences between these two types of belts:

  1. Design:
  2. Standard V-belts have a smooth, continuous surface on the inside, which comes in contact with the pulleys. On the other hand, cogged V-belts have notches or cogs on the inside surface. These cogs allow the belt to flex more easily and improve its flexibility and bending capabilities.

  3. Flexibility:
  4. The presence of cogs in cogged V-belts makes them more flexible compared to standard V-belts. This increased flexibility allows cogged V-belts to bend and wrap around smaller pulleys more easily. It also reduces the bending stress and heat generation, resulting in improved performance and longer belt life.

  5. Heat Dissipation:
  6. Cogged V-belts have better heat dissipation properties compared to standard V-belts. The cogs create additional surface area, which improves airflow and heat dissipation during operation. This helps to reduce heat buildup and minimize the risk of belt slippage or premature wear due to excessive heat.

  7. Power Transmission Capacity:
  8. Standard V-belts and cogged V-belts have similar power transmission capacity for most applications. However, cogged V-belts may have a slightly reduced power capacity compared to standard V-belts due to the presence of cogs, which can reduce the contact area with the pulleys. As a result, cogged V-belts are typically used in applications that require moderate power transmission.

  9. Noise and Vibration:
  10. Cogged V-belts generally produce less noise and vibration compared to standard V-belts during operation. The presence of cogs helps to reduce the vibration and noise caused by belt slippage or engagement with the pulleys. This makes cogged V-belts suitable for applications where noise reduction is important, such as in HVAC systems or household appliances.

  11. Application Suitability:
  12. Standard V-belts are commonly used in a wide range of industrial applications for power transmission. They are suitable for applications with larger pulleys and higher power requirements. Cogged V-belts, on the other hand, are often preferred in applications that involve smaller pulleys, tighter spaces, or where improved flexibility and reduced noise are desired.

It’s important to consider the specific requirements of the application and consult the manufacturer’s recommendations when choosing between standard V-belts and cogged V-belts. Understanding the key differences between these two types of belts can help in selecting the most appropriate option for a particular power transmission application.

What are the key differences between V-belts and other types of power transmission belts?

V-belts are a popular type of power transmission belts, but they differ from other types of belts in terms of design, construction, and specific applications. Here are the key differences:

1. Belt Profile:

V-belts have a trapezoidal or V-shaped cross-sectional profile, which gives them their name. This profile allows the belts to fit securely into V-shaped pulleys, providing effective power transmission and grip. Other types of belts, such as flat belts or timing belts, have different profiles suited for specific applications.

2. Power Transmission Method:

V-belts transmit power through frictional forces between the belt and the pulleys. As the belt wraps around the pulleys, the friction between the belt and the pulley surfaces allows the transfer of torque and power. In contrast, other belts, like timing belts or chain drives, use toothed profiles or interlocking mechanisms to transmit power, providing precise synchronization and higher torque transmission.

3. Load Capacity:

V-belts are designed to handle moderate to high loads, making them suitable for a wide range of applications. However, certain applications with heavier loads may require specialized heavy-duty V-belts or alternative belt types, such as synchronous belts or chain drives, which offer higher load-carrying capacities.

4. Speed Range:

V-belts are suitable for a broad speed range, but their limitations may vary depending on the specific design, material, and construction. Traditional V-belts may have speed limitations at extremely high speeds due to centrifugal forces and heat generation. High-speed V-belts or narrow V-belts are available for applications that require higher speeds. In contrast, timing belts and synchronous belts are designed for precise speed control and are commonly used in applications with strict speed requirements.

5. Tensioning and Maintenance:

V-belts require periodic tensioning to maintain proper grip and power transmission efficiency. Tensioning is typically achieved through manual adjustment or automatic tensioners. Other types of belts, such as timing belts or chain drives, often have fixed tensioning systems and require less frequent maintenance.

6. Noise and Vibration:

V-belts generally operate with lower noise and vibration levels compared to other types of belts, such as chain drives. The design and frictional nature of V-belts contribute to smoother operation and reduced noise generation, making them suitable for applications where noise and vibration control is important.

7. Applications:

V-belts are widely used in various applications, including industrial machinery, automotive systems, HVAC systems, and power transmission in general. They are versatile and can accommodate different power requirements. Other belt types, such as timing belts, are commonly used in precision positioning, robotics, or applications that require synchronous motion.

Overall, V-belts offer reliable and cost-effective power transmission for a wide range of applications. However, the selection of the appropriate belt type depends on factors such as load requirements, speed range, precision, noise considerations, and specific application needs.

What are the different types of V-belts available and their applications?

There are several types of V-belts available, each designed for specific applications and requirements. The most common types of V-belts include:

  1. Classic V-belts: Also known as conventional V-belts, these are the standard V-belts with a trapezoidal cross-section. They are widely used in various industrial applications for general power transmission, such as in HVAC systems, agricultural machinery, and industrial equipment.
  2. Narrow V-belts: Narrow V-belts are narrower than classic V-belts and have a narrower V-shaped profile. They are suitable for applications where space is limited or where high-speed ratios are required. These belts are commonly used in automotive engines, power tools, and small appliances.
  3. Wedge V-belts: Wedge V-belts, also known as narrow section V-belts, have a wider and deeper V-shaped cross-section compared to classic V-belts. This design allows for higher power transmission capacity and better resistance to belt slippage. Wedge V-belts are used in heavy-duty applications, such as in industrial machinery, mining equipment, and large agricultural machinery.
  4. Double V-belts: Double V-belts consist of two V-belts joined side by side. These belts provide increased power transmission capacity and are commonly used in applications where high torque is required, such as in heavy-duty machinery, pumps, and compressors.
  5. Variable Speed V-belts: Variable speed V-belts, also known as V-ribbed belts or multi-rib belts, have a ribbed surface on one side of the belt. This design allows for improved flexibility and enhanced power transmission efficiency. Variable speed V-belts are commonly used in automotive engines, industrial machinery, and appliances where variable speed control is required.

The choice of V-belt type depends on factors such as the power transmission requirements, space limitations, speed ratios, and the specific application. It is important to select the appropriate V-belt type based on these factors to ensure efficient and reliable power transmission.

In summary, the different types of V-belts available include classic V-belts, narrow V-belts, wedge V-belts, double V-belts, and variable speed V-belts. Each type has its own characteristics and is suitable for specific applications based on power transmission needs and requirements.
