Belts are common mechanical parts that are popular among many industries. There are various types of belts for you to choose. And some of them can also be further divided into many types such as the V Belt. It is the basic power-transmission belt, providing the best combination of traction, operating speed, bearing load, and service life.
The wedging action of the V belt in the pulley groove allows them to transmit higher torque at less width and tension than flat belts. Typically, it is endless. It requires larger pulleys than flat belts because of their greater thickness. When compared to the flat belt, it is far more superior at small center distances and high reduction ratios.
As is mentioned above, the V belt can be further divided into many other types such as the open-ended V belt, V-ribbed V belts, variable speed V belts, cogged V belt, and double-sided V belt, etc.
The first category is constructed the same as traditional ones, except that they are open-ended and do not need metal fasteners. This type of drive has a limited load capacity and tends to be expensive. And they are useful where obstructions make access to the drive belt difficult.
The second type of V belts is combined variable speed V belts that are banded together to achieve different speeds, strength and transmission capabilities. They are recommended for multi-sheave drives.
The third type allows for a greater range of speeds and better resistance to twisting while transitioning from one speed to another. It is recommended for variable-speed sheave drives that need to control speed to achieve a certain result.
The fourth category has a trapezoidal shape. It can either be a conventional or narrow raw edge cogged V belt. The former one is designed for high-tension drives, while the latter one can be applied for all drives.
The fifth type is characterized by its hexagonal cross-section shape. And its special shape enables it to be applied in serpentine reverse bend drives where a transmission may need to drive in reverse to generate power.
