V-belt is a low maintenance solution, which is suitable for medium and high power belt drive and can provide a high level of efficiency. V-belt has become the most common part in modern machinery, covering almost every industry from agriculture, automobile to pharmacy.
Hetuo Transmission has been studying what caused the premature failure of V-belts in many industries and how we can help you make full use of V-belts.
Visually inspect the belt for any of the following symptoms to prevent premature failure and unexpected shutdown:
1. The side wall wears rapidly.
Although sidewall wear will inevitably occur over time, rapid sidewall wear may be a sign of a bigger problem, because the most common cause may be pulley wear or damage. However, there are many other possible factors, such as using belts at extremely high temperatures, excessive oil, grease, moisture and other generally worn environments.
Solution: It is important to ensure that the pulley is replaced when replacing the belt, so as to ensure that you get the maximum benefit from the belt system. If the pulley wall is bright and shiny, it should be replaced.
2. Wear on the back
Most commonly, the back wear is the direct cause of the belt being pressed or pried onto the pulley, or there is some dislocation slack in the belt, which is damaged by the vibration of the idle pulley during operation. Although in some cases, a defective or worn rear idler will cause the rear side cover to wear, this is rare.
Solution: It is very important to ensure that the belt has the correct tension during installation. Even if the belt has been correctly measured and regarded as a "strip", it needs to be re-tensioned within 24-48 hours after installation.
3. The belt is soft and swollen
For some V-belts, too much contact with grease may be the source of disaster, because these products will cause the belt to soften and expand, so that it is no longer properly installed in the pulley groove. This problem can also be similarly attributed to the use of belt dressers.
Solution: If the belt works under extreme conditions, it may be that the belt cannot give full play to its potential. A simple belt guard can prevent foreign bodies including grease from polluting the transmission device, but care should always be taken to avoid using belt dressing.
If grease still exists, please consider using compound V-belts, because they are usually unaffected by grease, grease, water and common industrial solvents.
4. The belt slips and makes noise (rotating burn)
Wear or damage of pulley and incorrect tension may lead to rotational burn, which may lead to serious damage of belt, leading to damage or even premature damage. This may also be less common, due to the use of the wrong belt cross section or type, too much oil, too much grease or moisture, and insufficient winding on the small pulley.
Solution: This kind of wear means that it is necessary to check the tension of pulley and belt, because it means unnecessary wear under the tensioned belt and smooth pulley. You may find yourself needing a new pulley or re-tensioning the V-belt.
5. Separate belt cover
There is a lot to say about the damage that may be caused by forcibly pulling the belt onto the pulley or pulling the V-belt with incorrect tension, because this is the most common cause of belt damage, including cracks in the cover.
Solution: If you make sure that there is no foreign matter in the groove that causes the problem, then make sure to tension the belt regularly and order the correct size belt every time, which can help avoid this problem.
6. Cracking of bottom surface
Broken belt will cause serious problems, especially if it is not handled, it will affect the driving efficiency and eventually lead to belt failure. Overheated belts usually crack. Although this can't always be blamed, this kind of crack may also be caused by the pulley and the rear idler being too small or misaligned.
Solution: If your V-belt works in extreme temperatures, it may be time to consider buying a rubber belt that can withstand these temperatures without premature initial installation failure.
7. Lack of gears
No gears will cause belt slippage and failure. When missing teeth are found, the belt should be replaced immediately. The most common reasons why the belt may lack gears are overheating, too small pulleys or misaligned pulleys. It may also be caused by improper storage or too long time of the belt.
Solution: If your toothed belt works in extreme temperatures, it may be an ideal choice to consider a belt designed for these environments. In addition, using the laser calibration tool to confirm that the pulley has been calibrated correctly can eliminate possible causes and improve the operation of the machine.
8. The bushing is broken
A damaged bushing means that your drive is in a dangerous area. If the damage is too serious, the pulley may not be firmly installed on the shaft. Bushing may break due to excessive tension of the driver or the use of worn or damaged pulleys.
