Put your gears up against Convoloid^®

Enter your gear set. We rate your involute design and show, in real time, what the patented Convoloid^® tooth form does with the same envelope: more torque, longer life, or the same power from smaller, lighter gears.

Dimensions

Involute values use a simplified ISO 6336 / AGMA 2101 method with typical material allowables, for screening and comparison. Convoloid^® values are estimates calibrated to Gear Innovations' published comparisons and test history; exact performance comes from a profile computed for your application.
