Optimalisering van de roldiameter van bandtransporteurs

The design of any equipment invariably involves compromises between
technical and economic factors. For industrial equipment it is generally
possible to reduce the operating costs by increasing the initial costs. The
design variables over which the designer has some control may be adjusted
whithin certain limits to ensure that a particular item of the equipment
being designed meets the required specification. Such variables include
those relating to the geometrical size of the equipment; the diameter of
an idler in a conveyor has to be one of these variables. The influence of the
diameter of a roll on the indentation resistance and the consequences to the
rating life of the rolls and additional costs will be considered. Special
attention is paid to the radial load acting on the rolls. The material on
the belt causes a deformation of the belting and the resulting forces must
be kept in equilibrium by normal reactions on the rolls. These reactions can
be determined by theoretical analysis based on the mechanics of solids.
