DISADVANTAGES OF V-BELT PULLEYS

It is impossible to obtain the same tension in the belts we use side by side in the pulley due to the difference in the length, hardness and colitis of the V-belts we buy from the market.
Machine builders and machine maintainers know very well that some V-belts installed side by side are too tight and some are too loose.

In this case, the belt, which is too tense, will take all the load. It will not last long and will wear out. As it wears out, it will definitely wear out the grooves of the pulley. It will not be of much use to install a new belt in that channel, and it will wear out the new belt in a short time.

For this reason, the loss in V pulleys manufactured in DIN 2211 standard is between and . In non-standard randomly opened V pulleys, the loss is between -. This means that at least one of the four belts in the standard pulley is excessive and three of the four belts are excessive in the non-standard pulley. These situations cause the mokinas to become cumbersome and increase the cost.
The excessive groove depth in V pulleys is also a disadvantage. For this reason, they cannot be produced in small diameters. For example; a V pulley with a diameter of at least 125mm can be installed on a 50mm diameter coma shaft. If we want to reduce the revolutions six times, the counter pulley should be 750mm in diameter. A large and heavy pulley both tires the machine, increases the cost and gives a bulky appearance.
