Starting in 2010 the BEHAbelt Newsletter and website take on technical topics in the "Things you should know" section. Here we discuss topics that you may run into on your day- to- day routine at work or with a client. Our first topic of the year is Pulley Diameter. 1. "How does the pulley diameter impact the conveyor belt?"
- In general, the pulley diameter has a remarkable effect on the durability of the belt in use. Therefore, we recommend that you do not go below the recommended minimum pulley diameter mentioned within the BEHAbelt delivery program , instead chose a larger diameter. Undersized pulley diameters always reduce the durability of the belts because extreme flexing cycles reduce the materials quality. The mentioned min. pulley diameters always refer to an angle of grip of 180°. The flexing cycle specifies with how much degree the belt is enlacing the pulley. For more questions or comments on Pulley Diameters, contact us via the web email, or give us a call.
2. " Why do some belts "fizzle/wheeze within the application's machinery?"
-
The phenomenon of the fizzling belts within the machinery can have different reasons. In general sounds (fizzling, permanent or discontinuous wheezing) can be effected trough friction between the pulley and the belt. This friction can be caused by failure of the drive geometry (profile shape). Moreover sounds can appear when the belt slips over the pulley when the belt tension is to low or there is a underdimensioning of the belt. When the belt tension is to low, vibrations within the empty side rope may appear and the belt will derail off the pulley.
