%X This paper presents a computer-aided analysis to calculate sag in chain
drives exactly, which is commonly used in mechanical power transmission. With
sprocket rotating, sag in chain drives is different. Sag is a function of
meshing position of chain and sprocket. Because sag in chain drives is a variable,
the maximum and minimum sag can be obtained by numerical calculation. Corresponding
tensions in slack chain are obtained. A computer programme to calculate sag and
tensions in slack chain is programmed.
