Calculation on Variable Sag in Chain DrivesDOI: 10.4236/oalib.1102632, PP. 1-6 Subject Areas: Mechanical Engineering Keywords: Chain Drives, Variable Sag, Computer-Aided Analysis Abstract 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. Rong, C. (2016). Calculation on Variable Sag in Chain Drives.
