New Gear/Gearbox Optimization Software from Excel Gear


In response to the gear market’s need for optimization software, Excel-LentTM gear/gearbox design and analysis software has been developed by Excel Gear, Inc., and written in Visual Basics.Net. This software has been written by engineers who also design and manufacture gears for their own use, according to company President N.K. “Chinn” Chinnusamy.

“Although commercial software has long been available in the gear industry, it has been too expensive or too complicated to be used by engineers without specialized gear design knowledge,” he says. “Our software is specifically designed with a user-friendly interactive input screen providing defaults and options in accordance with the AGMA 2001 standard.”


The users of Excel-Lent software can easily navigate through the input screens to edit, analyze, and produce reports on the optimum gear and gearbox design for various industrial and other applications. “This software is not designed for any specific industry,” Chinnusamy says. “It can be used for machine tools, heavy materials handling equipment, or even the wind turbine industry. For the wind industry, for example, the designer needs a full understanding of all the operating loads on the gear members to arrive at the required power rating.”

The key calculations performed are the AGMA power rating and load calculations, including bending strength geometry factor (J) and pitting resistance geometry factors (I). Output from the software is a single page of data printed in a format that is easy to read and interpret. Other commercial software typically prints five or six pages of information, which may be confusing to most design engineers unless they are gear experts.
