Involute Tooth Spacing, Gear Profile and 3D Gear development with MATLAB® Graphical User Interface and Solidworks

Abstract

The present work has proposed an algorithm for the development of geometry of gear tooth space and complete gear profile using MATLAB® coding. It is executed through the MATLAB®Graphical User Interface (GUI) and developing 3D Gear solid model in Solidworks® environment. The work described here, has three phase approach for the construction of GUI. The initial analysis phase has considered the user requirement and critical specifications. Next in the design phase the layout was initiated, which has targeted in meeting out the calculations and plot of the technical aspects of gear. Finally the prototyping phase that involves the development and testing of GUI. The output of calculated values of the gear parameters are displayed in their corresponding text blocks. The single tooth plot provision provides the plot of the tooth space of the pinion or gear. The complete gear profile is provided in the pushbutton of pinion or gear plot. The visual display of the tooth spacing for Pinion and gear are comprehensible. The output coordinates of the points, XYZ, of involute and trochoidal root fillet are stored in the Excel/Text files. These were imported and curve was introduced and completed for 3D modeling of gear in Solidworks® part environment with suitable editing of the gear sketch. The outcome of the work supports a lot in investigating the critical geometric parameters of standard and non-standard spur gear system, and further stress and kinematic analysis.
