Belts can be defined as common mechanical parts which are quite popular and widely used in different industries. There are different types of belts to choose from, depending on the usages and requirements of every individual. Some of those industrial belts can again be further classified into different types and one such major and significant type is V-Belts. These can be stated as a power transmission belt of the basic level which offers the best combination of operation speed and traction. There are two other vital features available with this product namely high load bearing capacity and good service life.
The wedging action associated with V-Belts in the pulley groove can easily allow the material to transmit even higher amount of torque with less tension and width, when compared with other flat belts and mainly the function is endless. These require larger pulleys than the belts which are flat to look at due to their high thickness. If you gain compare these belts with other flat belts, then it can be said that the V ones are far more important in small centered distances and also when it comes to ratios with high reduction values.
It has already been mentioned earlier that V-Belts can be subdivided into various other types and some of the notable ones are V ribbed, open ended, cogged one, variable speed, double sided and more. The open sided ones are actually manufactured in the same manner, only the ends are open and this does not require any metal fasteners. These drives consist of limited load bearing capacity and are always expensive in nature. When obstruction makes access difficult in the drive belt, then these can be used without any tension.
Variable speed ones are another significant type of these belts which are banded all together in order to achieve various types of speed along with transmission capabilities and also different strength, at the same time. These are solely recommended for those drives which comprises of multi sheaves. The third category of these belts is used for generating different ranges of speeds and also for better resistance to different twisting methods. It generally works while speed transitioning takes place from one speed to another one. This is solely recommended for those which comprises of sheave drives along with variable speeds. It needs to control the speed in order to achieve a specific result.
There is another category of V-Belts and that consists of a trapezoidal shape.
It either comprises of a raw narrow edge or a conventional cogged shape. The former one can be used for different drives and the latter is solely used for drives with high tension. The last but not the least category is the cross section shape which is hexagonal in nature. As suggested from the name itself, this belt comprises of two Vs situated on each side. Due to its special shape it can be easily applied in various reverse serpentine drives where a reverse transmission might be needed for generating power.
