Product Description
Product Description
A conveyor will always consist of at least 2 pulleys, head pulley and tail pulley, with additional pulleys used depending on the configuration. Standard-duty pulleys are usually adequate for simple applications, but mine-duty and engineered pulleys are also available where heavy-duty pulleys are required.
Different kinds of conveyor pulleys
KONWEYOUR sells conveyor pulleys in all the following sub-categories:
Head pulleys
The head pulley is located at the discharge point of the conveyor. It usually drives the conveyor and often has a larger diameter than other pulleys. For better traction, the head pulley is usually lagged (with either rubber or ceramic lagging material).
Tail and CHINAMFG pulleys
The tail pulley is located at the loading end of the belt. It comes with either a flat face or a slatted profile (wing pulley), which cleans the belt by allowing material to fall between the support members.
Snub pulleys
A snub pulley improves the traction of the drive pulley, by increasing its belt wrap angle.
Drive pulleys
Drive pulleys, which can also be the head pulley, are driven by a motor and power transmission unit to propel the belt and material to the discharge.
Bend pulleys
A bend pulley is used for changing the direction of the belt.
Take-up pulley
A take-up pulley is used to provide the belt with the proper amount of tension. Its position is adjustable.

How do V pulleys handle variations in load capacity and speed?
V pulleys, also known as V-belt pulleys or sheaves, are designed to handle variations in load capacity and speed effectively. Here’s an explanation of how V pulleys accommodate these variations:
Load Capacity:
V pulleys handle variations in load capacity through the selection of appropriate belt and pulley sizes. The load capacity of a V-belt drive system depends on factors such as the width and thickness of the belt, the material of the belt, and the angle of wrap around the pulley. For higher load requirements, wider and thicker belts with higher tensile strength are chosen. By selecting the right combination of belt and pulley sizes, V pulleys can handle a wide range of load capacities, from light-duty applications to heavy-duty industrial applications.
Speed:
V pulleys handle variations in speed by adjusting the pulley diameter ratio. The speed ratio between the driving pulley and the driven pulley determines the speed at which the driven component operates. By using pulleys of different sizes, the speed ratio can be adjusted to achieve the desired speed. Increasing the diameter of the driving pulley or decreasing the diameter of the driven pulley will result in higher speed, while decreasing the diameter of the driving pulley or increasing the diameter of the driven pulley will result in lower speed. This flexibility allows V pulleys to accommodate a wide range of speed requirements in different applications.
It’s important to note that while V pulleys can handle variations in load capacity and speed, there are limits to their capabilities. Exceeding the recommended load capacity or operating at extremely high speeds can lead to belt slippage, reduced efficiency, and potential belt failure. Therefore, it’s crucial to adhere to the manufacturer’s guidelines and specifications when selecting V pulleys for specific applications to ensure optimal performance and longevity.
In summary, V pulleys handle variations in load capacity by selecting the appropriate belt and pulley sizes, while variations in speed are accommodated by adjusting the pulley diameter ratio. This flexibility allows V pulleys to effectively transmit power in a wide range of applications, providing reliable and efficient operation.
What is the role of V pulleys in HVAC systems and air conditioning units?
V pulleys play a significant role in HVAC (Heating, Ventilation, and Air Conditioning) systems and air conditioning units by facilitating efficient power transmission and driving various components. Here’s a detailed explanation of the role of V pulleys in HVAC systems and air conditioning units:
1. Blower Motor Drive:
In HVAC systems and air conditioning units, V pulleys are commonly used to drive the blower motor. The blower motor is responsible for circulating air through the system, facilitating the movement of conditioned air into the desired space. The V pulley provides the necessary power transmission to drive the blower motor efficiently.
2. Fan Drive:
V pulleys are also employed in HVAC systems to drive fans that assist in airflow and heat exchange. These fans include condenser fans, evaporator fans, and circulation fans. The V pulley connects the motor to the fan, enabling the fan to operate at the desired speed to enhance heat transfer and air circulation.
3. Belt-Driven Compressors:
In some HVAC systems and air conditioning units, V pulleys are used in conjunction with belt-driven compressors. The compressor is responsible for pressurizing and circulating the refrigerant throughout the system, facilitating the cooling process. The V pulley provides power transmission from the motor to the compressor, allowing for efficient operation of the cooling system.
4. Speed Control:
V pulleys allow for speed control in HVAC systems and air conditioning units. By using pulleys of different sizes, the speed ratio between the motor and the driven components can be adjusted. This flexibility in speed control enables precise airflow regulation and cooling capacity adjustment based on the specific requirements of the space being conditioned.
5. Belt Tensioning and Alignment:
Proper tensioning and alignment of the belts are essential for efficient power transmission and to prevent belt slippage or premature wear. V pulleys in HVAC systems are often accompanied by tensioners and idler pulleys that help maintain the correct tension in the belts and ensure proper belt alignment. Proper tensioning and alignment contribute to the overall efficiency and longevity of the system.
6. Noise Reduction:
V pulleys, along with properly tensioned belts, contribute to the smooth and quiet operation of HVAC systems and air conditioning units. The design of V pulleys, combined with the flexibility and smooth engagement of V-belts, minimizes noise generation, providing a quieter environment for occupants.
7. Durability and Maintenance:
V pulleys used in HVAC systems and air conditioning units are typically made of durable materials such as steel or aluminum. These materials can withstand the demanding conditions of HVAC operation, including high temperatures and continuous use. Regular maintenance, including inspection, lubrication, and occasional belt replacement, ensures the continued efficiency and reliability of the V pulley system in HVAC applications.
Overall, V pulleys are integral components in HVAC systems and air conditioning units, enabling efficient power transmission, precise speed control, and reliable operation of blower motors, fans, compressors, and other components. Their design features, combined with properly tensioned belts, contribute to the overall performance, airflow, and cooling capacity of HVAC systems, ensuring optimal comfort and energy efficiency in various indoor environments.
