The paper work is aimed at using Microsoft Visual Basic 6.0 to develop window based design software that combines flexibility with adequate users interface for the design of chain drives as an engineering transmission element. The chain drives considered are of two types; silent and roller. The calculations are programmed either through ‘known torque’ or ‘through guess pitch value’. The design software combines computational with sketch template in a single process to generate the required parameters of the chain drives. The package was tested with a number of case studies and the results obtained were quite satisfactory.
