PROGRESS IN QUALITY ASSESSMENT OF CONVEYOR IDLERS

摘要

The paper deals with the transformation of term quality according ISO standards into industrial practice. There are given investigations which give background for understanding of noise structure generated by a belt conveyor. It is shown that the role of idlers to generated noise by the belt conveyor is crucial. It has shone that for quality assessment of idlers, parameters connected with vibration has to be taken. The paper gives: general consideration on the quality term, describes dynamic properties of idler/(test rig), idler/(belt conveyor belt structure), presents results of computer simulations, gives the noise nature of the belt conveyor, describes the test rig, shows investigations on vibration generated by an idler, and gives vibration levels for idlers in different quality and condition.
