If you don’t maintain your belt drive properly, it can lead to several problems. Pulley misalignment or high or low voltage are a few indicators that indicate poor maintenance of your belt drive. It is wise to conduct a regular inspection to ensure proper alignment, correct tension and quick identification of abnormal wear signs. Once you are able to identify such wear signs, you would be able to maintain the performance of your V-belt and enhance its transmission. Sometimes, if the belt drive is not installed correctly can lead to premature failure. Hence, if you want to extend the shelf life of your belt, make sure to follow the installation process of belt and pulley correctly.
Storage and mishandling of belt can reduce the life of your V-belt. Proper sheave alignment is another step to make your belt last for a long time. There are few dos and don’ts to maximize the life of your V-belt. Here are some simple ways to make your V-belts last longer and that can prevent breakdown and unwanted stoppage
NEVER ROLL BELTS ON
Most of the time people tend to roll the belts in a hurry without loosening the motor. This is very unsafe and can often lead to a hard load on the bearing. It may also damage the belt as well as the sheave.
SIZE AND SHEAVE GROOVES MATTERS
Different V-Belts com in different shape size and profiles. It is your responsibility to buy a V-belt that matches with your sheave grooves. Sheave wear often is overlooked as most people are of the opinion that a rubber belt could never wear out a cast iron or steel sheave. However they can, you must use a groove measuring tool to check your sheave groove(s).
PROPER SHEAVE ALLIGNMENT AND BELT TENSION
In order to maintain your sheave alignment use laser tools as it checks both horizontal offset misalignment and also the vertical and horizontal angular misalignment. With a straightedge or string, it is difficult to detect misalignment. Furthermore, if you want your V-belt to last longer make sure that it has proper belt tension. Too little tension can create noise and excessive heat while too much tension can create band breakage. If the tension is not balanced it may lead to a reduction of the belt’s life.
ASSURE VENTILATION AND RE-CHECK BELT TENSION
V-belts are capable to produce excessive heat even in their normal operation. It is extremely important to make sure that your belt guarding is ventilated so that heat can dissipate easily. Further, when the belt matches the sheave groove, try to stretch it and heat up. This will cause the belt tension to normally change. This quick re-check and re-tightening can help you increase your belts life. If you are using a re-tensioned belt then use a laser tool to maintain the horizontal angular alignment.
The tips above if followed correctly can help you make a drastic difference in your V-belts life. It will not only increase its longevity but will also save you from countless hours of labor and unnecessary delay. One last advice would be to check the cleanliness of your belt, keep it away from various oil and dirt so that there is no operational problem in your belt.
