Gear Teeth Output Speed Ratio Calculator
Gear Teeth Output Speed Ratio is intended for the specific mechanics task described by its name. Enter input shaft rpm, driving gear teeth, driven gear teeth to calculate a result expressed in rpm. The formula works entirely in your browser and needs no account or external API. Ideal gear pair; no slippage or losses. This estimate is useful for comparing scenarios when the supplied measurements follow the stated assumptions.
How to use this calculator
- Measure input shaft rpm in the units indicated on the input label.
- Enter Driving gear teeth, Driven gear teeth.
- Read the rpm result, then compare alternative inputs to evaluate your own situation.
Gear Teeth Output Speed Ratio formula
input*driver/driven (rpm).
- The expression input*driver/driven combines Input shaft rpm, Driving gear teeth, Driven gear teeth. Follow the units on each input: the answer is expressed in rpm.
- Ideal gear pair; no slippage or losses.
Worked examples
Worked example: Gear Teeth Output Speed Ratio
Use these sample measurements: Input shaft rpm = 1600, Driving gear teeth = 20, Driven gear teeth = 50.
Compute input*driver/driven.
Using the example inputs, the result is 640 rpm. Use this value to verify the formula before changing the measurements.
Understanding the result
Interpret the output as rpm; it is not a measurement taken directly from a physical system.
Ideal gear pair; no slippage or losses.
Important notes
Ideal gear pair; no slippage or losses.
Review the input units, any required legal or engineering rules, and unusual edge cases before acting on this estimate.
