A random search method for optimum design of a pair of helical gears has been developed. The sequence of optimization consists of two principal components. The first is the selection phase, where the output is the starting solution for the design variables - module, facewidth, helix angle and number of teeth on the pinion. The input for the selection phase includes the application environment, approximate center distance, minimum helix angle, desired values of gear ratio, pinion speed and the power to be transmitted. The limits on each of the design variables and the constraints are imposed interactively during the first phase. A standard tooth form is assumed for the design. Standards published by the American Gear Manufacturers Association are employed for the design process. The second phase consists of the implementation of the optimization procedure to find the minimum weight. The method employs a random number as the search direction with the step size being altered based on the value of the constraints. A number of random directions are generated and a minimum in each of those directions are determined to form a set of feasible solutions. The optimum solution is then determined from the set of feasible solution. Graphs are presented during optimization to create a user interactive environment. The program generates a complete set of manufacturing data for the designed gear.

This thesis is a small part of a much larger work, the aim of which is to continue the transition from gear theory to gear practice. The thesis deals with some aspects of the testing and theoretical development of equiangular and plain polyangular gears respectively. Initial prototypes of the equiangular spatial involute gearing, a small subset of a general spatial involute gear set, developed in previous works are to be tested for both function and form. The tests, based on the principles of the single flank gear tester, investigate constancy of transmission ratio and use both electronic and mechanical means. The former of these highlights the shortcomings of some aspects of the experimental set up. Algebraic expressions are also developed for plain polyangular gearing, a more general form of spatial involute gearing. These equations demonstrate the links to the underlying kinematic principles and are, consequently, more robust. This is verified by their application to both the equiangular and plain polyangular cases. The expressions were checked by comparing their results to graphical and numerical models developed concurrently with the algebraic expressions. Initial investigations are also undertaken into turning the mathematical theory into gear machining theory. / Master of Engineering (Hons.)
