    The field of gear design is an extremely broad and complex area, and a complete coverage in any research work is not possible. In this work only parallel axis spur gear reduction unit which is the type, probably encountered most often in general practice, has been considered. A review of relevant literature in the areas of optimized design of spur gear indicates that compact design of spur gears involves a complicated algebraic analysis. A series of iterations is normally required to arrive at a practical combination of pinion teeth and module from their theoretical values. The present work describes the development of such a design methodology and diagnostic tool for determining the modes of failures for spur gear and also the causes of these failures have been studied. The ray diagram is also considered for finding out the minimum diameter and maximum transmission range. The focus is on developing a design space which is based on module and pinion teeth by using a simple logical statement in computer software. This is a much simplified approach for obtaining practical values of the module and pinion teeth for an optimum minimum centre distance between the two transmission shafts. Attention has been devoted to determine the exact mode of failure which dictated the design at the optimum conditions corresponding to the minimum centre distance for the design of gear reduction unit minimum dimensions
