MITCalc - Worm Gear v.1.14 MITCalc - Worm Gear is an application that can help you with the geometric design and strength check of worm gears. The application is developed in MS Excel, is multi-language and supports Imperial and Metric units. Related Resources: gears. Worm Gear Formula Table. Gear Engineering and Design Data. Worm gears are grouped into two general classes, fine-pitch worm gearing, and coarse-pitch worm gearing. 1) Fine-pitch worms and worm gears are generally used to transmit motion (linear or rotary) as opposed to power or torque. Using the right push-button, calculate the maximum power the particular worm gearing is able to transmit. 1.4 Speed (Worm / Worm gear). Enter the worm speed. The common worm speed is up to 3000 rpm, while extreme speed may be up to 40000 rpm. Worm gear speed is calculated from the number of teeth of both gears.
