The present report concerns a study of B.S.S, i 19^0 "Machine Cut Gears - Helical and Straight Spur'* for application to computer terminology^ Owing to the number of variables in the British Standard Specification gear design equations, it becomes a rather tedious matter to design a set of well proportioned gears direct from the Specification. A trial and error method seems to be the only approach. Equations with trial and error solution lend themselves to computer solution. This solution to gear design aims at reducing the number of variables from nine to four; namely, gear ratio, horsepower to be transmitted, speed of one gear in r.p.m., and hours of operation per day, all of which should be readily available to the designer. The programme developed will enable the design of a set of gears with these as the input, but depending upon the designer's experience and requirements, control over-rides have been allowed for adjustments. These include size of gears, number of teeth, type of material, helix angle and width of gears.
