How to Evaluate Velocity Ratio?

Velocity Ratio evaluator uses Velocity Ratio = Number of Teeth on Driven/Number of Teeth on Driver to evaluate the Velocity Ratio, Velocity Ratio formula is defined as the ratio of the rotational speed of the driven gear to that of the driver gear in a mechanical system, which helps to determine the gear train's efficiency and torque transmission. Velocity Ratio is denoted by i symbol.

How to evaluate Velocity Ratio using this online evaluator? To use this online evaluator for Velocity Ratio, enter Number of Teeth on Driven (T_d) & Number of Teeth on Driver (T_dr) and hit the calculate button.

FAQs on Velocity Ratio
