PARAMETRIC MODELING OF GEAR TRANSMISSIONS IN CAD SOFTWARE WITH DEFINABLE SHAFT AXIS POSITIONS

Abstract

This paper presents a practical example of using current CAD software solutions for improved modeling of geared power transmissions. The parameterization process used is for creating individual models, elements and assembly models of transmissions. The assembly model parametrically defines the correlation between elements of the assembly and defines the position of the shaft axis. This approach presents an automation of the modeling process, a quick and effective approach to forming and changing technical documentation. The suggested approach forms a basis for automation of the complete design process for geared power transmissions. This paper also presents models of practically applicable geared transmissions which verifies the quality and efficiency of the development process, compared to a conventional approach. Practical examples also show ways of creating models and use of development processes. Models are developed for two-stage and three-stage geared power transmissions.
