Application of the graphical computer simulation methods to determine the optimal settings for gearing machines

Abstract

© Published under licence by IOP Publishing Ltd. The article describes an example of the practical application of graphic computer simulation methods to determine the setup parameters of gear-broaching machines. The adjustment parameters found using computer simulation methods provide a favorable distribution of lateral clearances to achieve the design positions of the total contact spots along the sides of the valleys of the gears. The determination of the adjustment parameters consists in imitating the process of gearing which results in 3D models of bevel wheels. The troughs of the interacting 3D wheel models are dissected along the inner, middle and outer cones. Graphic run-ins were performed for the side profiles of the wheel cavities along the length of the tooth. The graphs of changes in the lateral clearances of the tooth tooth profiles are constructed and the best position of the extrema in the middle part of the side surface of the tooth teeth is selected. Thanks to the application of graphical modeling methods, it becomes possible to exclude from the total adjustment error the errors of parts and moving machine parts that are individual for each gear-broaching machine.
