Velocity Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity Ratio = Number of Teeth on Driven/Number of Teeth on Driver
i = T_d/T_dr
This formula uses 3 Variables

Variables Used

Velocity Ratio - Velocity ratio is the distance through which any part of a machine moves to that which the driving part moves during the same time.
Number of Teeth on Driven - Number of Teeth on Driven is the count of number of teeth on the driver.
Number of Teeth on Driver - Number of Teeth on Driver is the count of number of teeth on the driver.

STEP 1: Convert Input(s) to Base Unit

Number of Teeth on Driven: 15.6 --> No Conversion Required
Number of Teeth on Driver: 20 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

i = T_d/T_dr --> 15.6/20

Evaluating ... ...

i = 0.78

STEP 3: Convert Result to Output's Unit

0.78 --> No Conversion Required

FINAL ANSWER

0.78 <-- Velocity Ratio

What id velocity ratio?

Speed ratio (or velocity ratio) of gear train is the ratio of the speed of the driver to the speed of the driven or follower(or) the ratio of speeds of any pair of gears in mesh is the inverse of their number of teeth.

How to Calculate Velocity Ratio?

Velocity Ratio calculator uses Velocity Ratio = Number of Teeth on Driven/Number of Teeth on Driver to calculate 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 calculate Velocity Ratio using this online calculator? To use this online calculator for Velocity Ratio, enter Number of Teeth on Driven (T_d) & Number of Teeth on Driver (T_dr) and hit the calculate button. Here is how the Velocity Ratio calculation can be explained with given input values -> 0.78 = 15.6/20.

FAQ

What is 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 and is represented as i = T_d/T_dr or Velocity Ratio = Number of Teeth on Driven/Number of Teeth on Driver. Number of Teeth on Driven is the count of number of teeth on the driver & Number of Teeth on Driver is the count of number of teeth on the driver.

How to calculate 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 is calculated using Velocity Ratio = Number of Teeth on Driven/Number of Teeth on Driver. To calculate Velocity Ratio, you need Number of Teeth on Driven (T_d) & Number of Teeth on Driver (T_dr). With our tool, you need to enter the respective value for Number of Teeth on Driven & Number of Teeth on Driver and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Velocity Ratio?

In this formula, Velocity Ratio uses Number of Teeth on Driven & Number of Teeth on Driver. We can use 3 other way(s) to calculate the same, which is/are as follows -

Velocity Ratio = Product of Number of Teeth on Driven/Product of Number of Teeth on Drivers
Velocity Ratio = Speed of Last Driven Pulley/Speed of First Driver
Velocity Ratio = Product of Diameters of Drivers/Product of Diameters of Drivens
