Because of error of manufacture and assembly, the output kinematic characteristics of a Geneva mechanism will be different from the desired ones. In this paper an analysis procedure is developed to find the error in acceleration and jerk of internal Geneva mechanisms from the viewpoint of probability theory. A synthesis procedure, using nonlinear programming techniques, of distributing tolerances and clearances in the mechanism for specified maximum allowable errors in acceleration and jerk is discussed. The application of analysis and synthesis procedures is demonstrated by means of numerical examples.
