Tension of the V-belt
Thread Content
There is an air-cooled unit with a belt of 5V1700; how can one determine its tension level? Is there any empirical value for this? I hope everyone can help!
Press down from the middle; an offset of about 2–3 cm is sufficient
There are differences between the nominal values and empirical values, both for new V-belts and old V-belts.
It is related to the diameter of the pulleys and the distance between their centers. When aligning the belts, it is necessary to measure the parallelism of the end surfaces of the pulleys, as well as the tension of the belts.
Based on experience, the second floor can serve as a reference. However, this is not fixed; generally, when operating at full load for extended periods, it is advisable to adjust it more tightly. Both the pulleys and belts will heat up, and the belt may expand, and vice versa.
This is determined based on experience; you can tell how tight the belt is by pressing it with your hand.
It’s very simple; just follow what’s described on the second floor. If the belt is too tight, it’s not good for the bearings. The key is to ensure that the two pulleys are parallel – you can use a string to pull them and check accordingly.
The belt at 1700 can be pressed down by one finger to a height of –2CM
