There comes the role of V-belt pulley as sit is created to transmit power between axles with the help of belts. Such V-belt pulleys are highly in demand of its robust contribution and high-speed transformation of power.
V-belts are transmission belts that can be used to transform power from drive shaft to driven shaft. V-belts are popularly used in different range of industrial and automotive application including pumps, conveyors and heavy-duty machines. They are designed to help them grip the pulleys to transmit friction.
How does the pulley work?
According to the Business wire, industrial pulleys are becoming the first choice of smart idlers who are seeking mechanical advancement to drive growth in their operations.
As the most proficient material handling tool, V-belt pulleys are certified for smooth operations, heavy load-carrying capacities and low friction on surfaces. As per the reports, experts forecasted a 4% growth for the global industrial pulley market.
Thus, by providing a compact and efficient means of transmitting power, different types of v belt pulleys help improve system efficiency, reduce maintenance costs, and increase the overall reliability of mechanical systems. Choosing the correct type and size of V-belt is important for several reasons:
- V-belt pulleys efficiently transform power by improving the overall efficiency of the system.
- It should also be reliable as the V-belt can slip out more quickly, resulting into accident and bearing additional maintenance.
- You should also check if the V-belt is compatible with the other components like shape, design, material and size.
- You should select the correct belt tension as tension is important for power transmission and long-term reliability for the industrial application.
- You should also check if the belt is able to operate in different circumstances and can be tolerant to moisture, chemicals, temperature and other factors, affecting the long-term durability of the application.
Thus, it is ideal to check all these aspects before finalizing the V-belt pulleys for your industrial application. Besides, here are other factors that you should determine before investing in highly-durable pulleys.
V-Belt Types
There are many possible types of V-belts available:
- Light Duty – Suitable for light duty applications typically using fractional horsepower motors
- Classical Heavy Duty – Wide range of sizes
- Molded cogs – cogs allow the use of smaller diameter pulleys and provide heat dissipation; Raw edge sidewalls prevent slippage
- Wedge – narrower, deeper profile with greater power potential than classical V-belts; Allows for smaller, more compact drives
- Wedge Cogged – Same properties as a wedge, but cogged for greater flexibility and heat dissipation
- Banded – Two or more V-belts are joined to form a single belt which allows the belt to operate as a single belt with uniform load distribution and wear.
Comparing all types of V-belts
Here is a detailed comparison between standard V-Belts, multiple V-belts and narrow V-belts.
| Descriptions | Standard V-belts | Multiple V-belts | Narrow V-belts |
|---|---|---|---|

| Cost | They are the most economical option for industries | They are more expensive due to the multiple belts | They are typically more expensive than standard V-belts |
| Maintenance | They require routine maintenance | Routine adjustments are necessary for this type. | They require less maintenance due to their smaller size |
V-Belt Sizes
V-belts are belts with trapezoidal cross-sections. Like other types of belts, they are used to transmit power or torque from the driving component to the driven component. Their design facilitates grip on the roller components (i.e., pulleys) during operation, reducing the risk of slippage and increasing the stability of the system’s output.
These components come in many variations, each offering unique characteristics that make them suitable for use in a wide variety of applications. examples include:
- A type V-belt with 1/2 inch top width
- B type V-belt with top width of 21/32 inches
- C type V-belt with 7/8 inch top width
- D type V-belt with top width of 1 1/4 inches
- E type V-belt with top width of 1 1/2 inches
Choosing the Right Size for efficient performance:
Measure the width of the belt to determine which type of belt is right for your application. Most belts are the belt type with a gauge of 1/2″. If the belt measures 5/8″ it is classified as a Type B belt.
You may see a belt described as an AX type. X means it has a cogwheel design or notch in the belt. Cogged profiles enhance power transfer and are generally used only for industrial applications due to their high cost.
Tips for selecting the accurate belt size:
Here are some tips that you should consider for selecting the accurate belt size.
- The belt profile, or the style and shape of the belt, is being consolidated.
- The outside diameter, or distance around the pulley, as measured between the edges of the groove.
- The center diameter is the center or distance between the pulley shafts in the transmission. V-belt transmission is limited by the center distance, which should not exceed three times the diameter of the largest pulley, otherwise significant slippage may occur.
- Grooves, including the number of grooves on the pulley and the angle and width of the flange.
- The pitch diameter, or the diameter of the pulley where the belt is engaged, is critical to the power-to-weight ratio of the drive.
- Arc of contact is the degree to which the belt wraps around the pulley.
