Computer-aided selection of roller chain drives

Abstract

This work presents a computer-aided analysis for the selection of roller chain drives, which are commonly used in mechanical power transmission systems. Computer programs are written and proposed to improve the traditional method of drive selection for the roller chain drives. The algorithms are mainly based on the existing equations for the mechanics of the drives, including the geometry and the power transmission capabilities. The purpose of attempting to computerize the selection procedures is to reduce the number of tables and charts that are required in traditional selection routines. In addition, it is also intended to cut down the amount of iteration and calculation work performed. To evaluate the accuracy and limitations of the proposed programs, comparisons are made with the existing examples of drive selections. It is found that the programs implemented in the present selection process are able to substitute for most of the traditional selection charts and tables. Furthermore, the selection using the proposed methodology can be performed in a shorter time owing to the computer-generated process.
