Tensions in Straight and Curvilinear Belt Conveyers

Abstract

This paper presents a simplified method of tension calculations in belt conveyers, suggesting the same approach regardless of whether belts are straight or curvilinear. A Key Diagram is introduced for the quick identification of critical tensions for all basic conditions. It is common practice to use an analytical method for the calculation of tensions and horsepower of more complicated belt conveyers, especially curvilinear belt conveyers. The big advantage of this method is that it permits the establishment of tension values for the design of concave and convex curves and also for the design of drive and take-up when not located at conveyer ends. However, the so-called analytical method has a distinct disadvantage in practical engineering—it is tedious and time-consuming. The purpose of this paper is to present a faster way to find all belt tensions necessary for the proper design or selection of conveyer components.
