Abstract
After a brief introduction the paper gives a discussion of the steps of sprocket design with the ultimate aim of keeping the flutter to a minimum. — First the selection of the proper sprocket-tooth pitch is considered, then the steps required in arriving at the proper basic tooth profile, and finally the modified tooth profile are illustrated by an example. — Curves of theoretical flutter versus per cent of film shrinkage are given for several cases for a 24-tooth sprocket. The effect of number of teeth is also shown by curves. — An analysis of film and friction forces gives a clue to proper film guide design. — A word about sprocket-tooth shapers and results obtained from an experimental sprocket conclude the paper. — The degree of accuracy and the directness of the method, as well as the resulting optimum performance, are noteworthy.
