Development of Gear Design Software Package

Abstract

This report presents an overview of the Gear Design software package developed by us. This package was developed as an attempt to dive into interdisciplinary pool of engineering, Often during designing gears for gearboxes or other transmission systems, the engineer faces the problem of extracting information from standard data- books, manually calculating the forces and torques and then solving for module. This process is highly inefficient and time- consuming and does not guarantee optimized design or does not allow the engineer to view the variations in parameters at a single glance. Thus in order to make the engineer's job easy this package has been developed using fundamental programming practices and open source language, Python. The package features an ergonomic graphical user interface(GUI). It automatically generates 3D CAD model of the gear pair and also auto- generates a logically complete industrial grade report. Python-based gear design software with GUI automatically calculates optimum module, generates 3D CAD models, and creates industrial-grade reports. Optimization shows face-width factor of 12-15 gives safe design. For optimized safe design face-width factor must be taken between 12 to 15. Optimum BHN is 550 to 400 for lower number of pinion teeth to higher number of pinion teeth. For Grade 1-5 both module with and without Buckingham load is same. For Grade 6-12 module considering Buckingham Load =primary module +1.
