Chevron Conveyor Belt | |||||||
Chevron conveyor belt is composed of belt carcass and pattern. Pattern shape and height(depth) may be different because of different conveyes material and gradient of conveyors.
With smooth surface conveyor belts, the maximum conveying angle of inclination is approximately 20° depending on the material. Using chevron cleated belts makes steeper angles of inclinations up to 40° possible, which allows for higher lift in lesser space.
Chevron conveyor belts have rubber cleats that are integrally vulcanized with the top cover of the belt. These profiles are made with highly abrasion resistant rubber types and are offered in softer compounds (45 to 50 Shore hardness) as also 60 shore materials. The profiles are shaped in such a manner that there is no need for special idlers and these can be run on conventional conveyors. The pitch between 2 cleats ensures a smooth ride over return idlers.
Characteristics
BELT WIDTH
Depending upon the profile, chevron belts are available in widths from 600 mm to 2300 mm.
EDGES
Chevron Belts are normally supplied with cut edges. However, Belts with moulded edges can also be supplied.
PATTERNED CONVEYOR BELT
Wavy-top conveyor belts, herringbones conveyor belts, and a host of other options are available in open ends or built endless. Multi-V constructions with 1/4 inch (6 mm) height are also available.
SPECIAL PROFILE WEIGH CONVEYOR BELT
We manufacture special profile weigh feeder belts for use in thermal power plants and cement factories. These are highly caliberated seamless belts with side profiles and centre guides.
CUSTOM BELTS
We have the expertise to design a new chevron profiled design to meet your needs with it’s experience in CZPT manufacturing and product designing.
Steel Cord Conveyor Belt | |||||||
As conveyor systems get longer, and handle increased volumes and tonnage, the belt itself needs to get stronger. Steel cable delivers higher strength, and decreased elongation compared to fabric; and steel cord belts deliver cheaper and more reliable performance for any system with long conveying distances or high lifts.
Steel Cord Rubber Conveyor Belts is composed of core glue, steel wire rope, cage cover layer and edge glue. It has the characteristics of CZPT proof, moth proof, anti-aging and good heat resistance.

Corrugated Sidewall Conveyor Belt | |||||||
Corrugated Sidewall Belting ensures long life service and best operational outcomes within your bulk handling operation.
Corrugated Sidewall Belts consists of 2 corrugated sidewalls bonded to a base belt. This makes it possible to design a steep angled conveyor system that will move a far greater volume of bulk material at any angle of inclination.
Depending on the types of cleats and height of the sidewalls, we can actually move product at angles up to and including 90°.
Conveyors can be designed in almost any conceivable configuration and to fit in even the most confined areas.
Instead of having to transfer material from 1 conveyor to another, corrugated sidewall belting simply changes the planes of travel.
Our corrugated sidewall belting ensures material handling and retention of material within the belts sidewalls whilst providing optimal performance.

Pipe Conveyor Belt | |||||||
The tubular conveyor belt is a new type of conveyor belt with a ribbon skeleton (EP cloth, steel cord, etc.) as the skeleton and high elastic, high wear-resistant and high strength rubber as the working surface. It is mainly used for conveying powder and granular materials that are polluted to the environment. When working, the rubber belt changes from a flat shape to a ∪ shape, and finally into a tubular shape, folding the material to achieve a closed conveying process.
The main features of the belt
1, the material closed transport, not only to protect the material, but also to protect the environment.
2, large Angle transmission, transmission Angle can generally reach 30 degrees.
3, the transmission line can be arranged according to the space curve.

Are there any alternatives to V-belts for power transmission applications?
Yes, there are several alternatives to V-belts for power transmission applications. These alternatives offer different advantages and may be suitable for specific requirements. Here are some commonly used alternatives:
- Synchronous Belts:
- Flat Belts:
- V-Ribbed Belts:
- Chain Drives:
- Gear Drives:
- Direct Coupling:
Synchronous belts, also known as timing belts, are toothed belts that provide precise and synchronous power transmission. They have teeth on the inner side that mesh with corresponding grooves on the pulleys, eliminating slippage and ensuring accurate power transfer. Synchronous belts are commonly used in applications that require precise positioning, high torque transmission, or low maintenance.
Flat belts are thin, flexible belts that transmit power by friction between the belt and the pulleys. They offer a simple and cost-effective solution for power transmission. Flat belts are available in various materials, such as rubber, leather, or fabric-reinforced synthetic materials. They are suitable for applications with moderate power requirements and can be used in both light-duty and heavy-duty applications.
V-ribbed belts, also known as multi-rib belts or serpentine belts, are similar to V-belts but have a different cross-sectional shape. They have a flat or shallow V-shaped profile with ribs on the inner side, which engage with corresponding grooves on the pulleys. V-ribbed belts offer higher power transmission capacity and reduced slip compared to standard V-belts. They are commonly used in automotive applications, such as engine accessory drives.
Chain drives use a series of interconnected links to transmit power. They are known for their high strength, durability, and ability to handle heavy loads. Chain drives are commonly used in applications that require high torque transmission, such as industrial machinery, motorcycles, or bicycles. However, chain drives require periodic lubrication and maintenance to ensure proper operation.
Gear drives utilize interlocking gears to transmit power. They offer high efficiency, precise power transmission, and the ability to transmit large amounts of torque. Gear drives are commonly used in applications that require high precision, such as robotics, machine tools, or automotive transmissions. However, they can be more complex and expensive compared to belt drives.
In some cases, power transmission applications may utilize direct coupling, where the motor shaft is directly connected to the driven equipment without the use of belts or other intermediate components. Direct coupling offers high efficiency, compactness, and eliminates the need for belt maintenance. It is commonly used in applications with high torque requirements or where precise alignment is critical.
The choice of the alternative to V-belts depends on various factors, including the specific power transmission requirements, space limitations, cost considerations, maintenance needs, and the desired level of precision. It is important to evaluate these factors and consult with experts to select the most suitable alternative for a particular application.
What are the factors that affect the lifespan and efficiency of V-belts?
The lifespan and efficiency of V-belts can be influenced by several factors. Here are the key factors that can affect the performance of V-belts:
- Belt Tension:
- Belt Alignment:
- Belt Condition:
- Maintenance and Lubrication:
- Operating Conditions:
- Load and Application:
Proper belt tension is crucial for the longevity and efficiency of V-belts. Insufficient tension can cause slippage, while excessive tension can lead to excessive load on the belt and other components. It is important to follow the manufacturer’s recommendations for the correct tension range.
Poor belt alignment can cause uneven wear, increased friction, and reduced efficiency. Misaligned pulleys can cause the belt to run at an angle, resulting in premature wear and potential failure. Regularly check and adjust the alignment of pulleys to ensure proper belt tracking.
The condition of the V-belt itself is a significant factor in its lifespan and efficiency. Regularly inspect the belt for signs of wear, cracks, fraying, or glazing. Replace worn-out or damaged belts promptly to avoid further issues.
Proper maintenance and lubrication can significantly extend the lifespan of V-belts. Adequate lubrication reduces friction and heat buildup, which helps to prevent premature wear and cracking. Follow the manufacturer’s recommendations for lubrication intervals and use the appropriate lubricant.
Operating conditions, such as temperature, humidity, and exposure to chemicals or contaminants, can affect the performance of V-belts. Extreme temperatures can cause the belt material to deteriorate, while exposure to chemicals or contaminants can lead to belt degradation. Ensure that the operating conditions are within the recommended range for the specific V-belt.
The load and application requirements also impact the lifespan and efficiency of V-belts. Excessive loads or improper application can cause excessive stress on the belt, leading to premature failure. Ensure that the V-belt is appropriately sized and rated for the specific load and application.
By considering these factors and implementing proper maintenance practices, such as regular inspections, correct tensioning, alignment checks, and appropriate lubrication, you can maximize the lifespan and efficiency of V-belts in your applications.
What are the common causes of V-belt failure and how can they be prevented?
V-belt failure can occur due to various factors, and understanding the common causes is essential for preventing premature belt failure and ensuring reliable operation. Here are some common causes of V-belt failure and preventive measures:
- Misalignment: Misalignment between the pulleys can cause excessive wear, uneven load distribution, and belt slippage. To prevent misalignment, ensure proper pulley alignment during installation and regularly inspect and adjust the pulleys as needed.
- Over-tensioning or under-tensioning: Incorrect belt tension can lead to excessive stress or slippage. Over-tensioning can cause accelerated wear, while under-tensioning can result in belt slipping and reduced power transmission. Follow the manufacturer’s recommended tension guidelines and use a tension gauge to achieve the proper tension for the specific V-belt.
- Pulley damage: Damaged or worn-out pulleys can cause belt damage and premature failure. Inspect the pulleys regularly for signs of wear, such as grooves, cracks, or deformation. Replace any damaged pulleys promptly to prevent belt damage.
- Contamination: Contaminants such as dirt, debris, oil, or chemicals can affect the belt’s grip and cause accelerated wear. Keep the belt and pulleys clean and free from contaminants. Regularly inspect the environment and implement appropriate measures to prevent contamination.
- Excessive heat: High temperatures can cause belt degradation, leading to reduced strength and increased wear. Ensure proper ventilation and cooling in the belt drive system. If the application generates excessive heat, consider using heat-resistant belts or implementing cooling measures.
- Excessive load: Overloading the V-belt beyond its capacity can cause excessive stress and lead to premature failure. Ensure the V-belt is appropriately sized for the application and consider factors such as torque, horsepower, and load requirements. If the load exceeds the belt’s capacity, consider using a higher-rated belt or alternative power transmission methods.
- Age and wear: Over time, V-belts naturally wear out and lose their effectiveness. Regularly inspect the belts for signs of wear, such as fraying, cracking, or glazing. Replace worn-out belts as part of a preventive maintenance schedule to avoid unexpected failures.
Preventive measures to reduce V-belt failure include regular inspections, proper installation, correct tensioning, pulley maintenance, cleanliness, temperature management, load monitoring, and timely replacement. Following manufacturer’s guidelines, conducting routine maintenance, and addressing any issues promptly will help extend the lifespan and reliability of V-belts in power transmission systems.
In summary, common causes of V-belt failure include misalignment, incorrect tensioning, pulley damage, contamination, excessive heat, excessive load, and age/wear. By implementing preventive measures and conducting regular maintenance, these causes can be minimized, ensuring optimal V-belt performance and longevity.
