Speed of bigger pulley given speed of smaller pulley Solution

STEP 0: Pre-Calculation Summary

Formula Used

Speed of Larger Pulley = Diameter of Small Pulley*(Speed of Smaller Pulley/Diameter of Big Pulley)
n₂ = d*(n₁/D)
This formula uses 4 Variables

Variables Used

Speed of Larger Pulley - (Measured in Radian per Second) - Speed of Larger Pulley can be defined as the number of revolutions the larger sized pulley makes in a given unit of time.
Diameter of Small Pulley - (Measured in Meter) - Diameter of Small Pulley is the distance from side to side of the flat of the Small pulley.
Speed of Smaller Pulley - (Measured in Radian per Second) - Speed of Smaller Pulley can be defined as the number of revolutions the smaller-sized pulley makes in a given unit of time.
Diameter of Big Pulley - (Measured in Meter) - Diameter of Big Pulley is the distance from side to side of the flat of the Big pulley.

STEP 1: Convert Input(s) to Base Unit

Diameter of Small Pulley: 270 Millimeter --> 0.27 Meter (Check conversion here)
Speed of Smaller Pulley: 640 Revolution per Minute --> 67.0206432731694 Radian per Second (Check conversion here)
Diameter of Big Pulley: 810 Millimeter --> 0.81 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n₂ = d*(n₁/D) --> 0.27*(67.0206432731694/0.81)

Evaluating ... ...

n₂ = 22.3402144243898

STEP 3: Convert Result to Output's Unit

22.3402144243898 Radian per Second -->213.333333333333 Revolution per Minute (Check conversion here)

FINAL ANSWER

213.333333333333 ≈ 213.3333 Revolution per Minute <-- Speed of Larger Pulley

(Calculation completed in 00.020 seconds)

Pitch diameter of big pulley of V Belt drive

Go Diameter of Big Pulley = Diameter of Small Pulley*(Speed of Smaller Pulley/Speed of Larger Pulley)

Correction Factor for Industrial Service given Design Power

Go Correction Factor for Industrial Service = Design Power of Belt Drive/Power transmitted by belt

Transmitted Power given Design Power

Go Power transmitted by belt = Design Power of Belt Drive/Correction Factor for Industrial Service

Design Power for V Belt

Go Design Power of Belt Drive = Correction Factor for Industrial Service*Power transmitted by belt

Speed of bigger pulley given speed of smaller pulley Formula

Speed of Larger Pulley = Diameter of Small Pulley*(Speed of Smaller Pulley/Diameter of Big Pulley)
n₂ = d*(n₁/D)

Define a Belt Drive?

A belt drive is a transmission system that uses a flexible strip to transfer power. The turning disk is connected by a belt drive to the electric motor. A rubber belt drive is used to transfer power from one pulley to another.
