The thesis describes the development of a computer-aided design and computer-aided draughting package of industrial gearboxes for transmitting power between shafts having parallel major axes. The package mainly consists of the following functions: (a) Determination of gear tooth numbers from the properties of continued and conjugate fractions (b) Generation of gear teeth by a rack-type cutter (c) Calculation of gear tooth profile and production of gear tooth grid for finite element stress analysis (d) Detailed strength analysis and design of a spur or helical, external or internal, standard or modified, single- or double- reduction gear set based on the ISO gear standards (e) Shaft design and analysis (f) Bearing selection and analysis (g) Production of the working drawings of the main gearbox components. This package works on the IBM PC and its compatible machines, operates in an interactive mode, combines the experience of the designer with the power of the computer, and produces substantial savings in time and cost over conventional design methods. Design examples illustrating this package are given. In addition, the maximum tooth root bending stresses have been studied by using finite element techniques and the results have been compared with those using the ISO gear standards.
