Which one do you need?
- Gear Ratio & Output Speed Calculator
- Calculate the ratio, output speed and output torque of a single or multi-stage gear train from tooth counts, input RPM, input torque and stage efficiency.
- V-Belt Length Calculator
- Calculate V-belt pitch length from two pulley diameters and center distance, or solve the center distance a standard belt needs. Includes wrap angles.
- Pulley Speed & Ratio Calculator
- Solve any belt drive unknown: driven RPM, driver RPM or either pulley diameter. Get the drive ratio, belt surface speed in FPM and m/s, and shaft torque.
