Relationship between V-belt drive tension and frequency
Thread Content
What is the relationship between the tension of a V-belt drive and its frequency? When installing a V-belt, the tension is adjusted while simultaneously measuring the vibration frequency of the belt – what is the relationship between these two factors?
Vibration indicates that the V-belt is loose and the tension is insufficient. As the tension in the V-belt drive increases, elastic sliding decreases and the vibration frequency rises; when the tension is appropriate, the V-belt vibrates only slightly.
When installing a V-belt, there is a preload. When this preload is appropriate, the tension on the loose side and the tight side of the belt is roughly equal; if the difference in tension between these two sides is too large, vibration problems occur, and it is necessary to adjust the preload again.
