Power Transmitted Solution

STEP 0: Pre-Calculation Summary

Formula Used

Shaft Power = 2*pi*Speed of Rotation*Torque applied
W_shaft = 2*pi*N*τ
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Shaft Power - (Measured in Watt) - Shaft Power is the mechanical power transmitted from one rotating element of a vehicle, ship, and all types of machinery to another.
Speed of Rotation - (Measured in 1 per Second) - The Speed of Rotation is the speed at which an object rotates or revolves is called rotational speed. Unlike linear speed, it is defined by how many rotations an object makes in a period of time.
Torque applied - (Measured in Newton Meter) - Torque applied is described as the turning effect of force on the axis of rotation. In brief, it is a moment of force. It is characterized by τ.

STEP 1: Convert Input(s) to Base Unit

Speed of Rotation: 17 1 per Second --> 17 1 per Second No Conversion Required
Torque applied: 46 Newton Meter --> 46 Newton Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_shaft = 2*pi*N*τ --> 2*pi*17*46

Evaluating ... ...

W_shaft = 4913.45091021444

STEP 3: Convert Result to Output's Unit

4913.45091021444 Watt -->4.91345091021444 Kilowatt (Check conversion here)

FINAL ANSWER

4.91345091021444 ≈ 4.913451 Kilowatt <-- Shaft Power

Ratio Factor for Bevel Gear

Go Ratio Factor for Bevel Gear = (2*Number of Teeth on Bevel Gear)/(Number of Teeth on Bevel Gear+Number of Teeth on Pinion*tan(Pitch Angle for Bevel Gear))

Velocity Factor for Generated Teeth of Bevel Gear

Go Velocity Factor for Generated Teeth = 5.6/(5.6+sqrt(Pitch Line Velocity of Bevel Gear))

Power Transmitted

Go Shaft Power = 2*pi*Speed of Rotation*Torque applied

Bevel Factor

Go Bevel Factor = 1-Face Width of Bevel Gear Tooth/Cone Distance

Velocity Factor for Cut Teeth of Bevel Gear

Go Velocity Factor for Cut Teeth = 6/(6+Pitch Line Velocity of Bevel Gear)

Power Transmitted Formula

Shaft Power = 2*pi*Speed of Rotation*Torque applied
W_shaft = 2*pi*N*τ

Define power?

power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity
