Square Thread Power Screw Efficiency Formula & Calculator
power screw efficiency (η) calculator - step by step calculation, formula & solved example problem to find the efficiency of square thread power screw in mechanical engineering for power transmission. Load in Newton F, square thread pitch distance l in mm & torque T in Nm are the key terms of this calculation.
For power transmission in mechanical engineering, the below mathematical formula is used to calculate the efficiency of the power screw
The below step by step solved example problem may helpful for users to understand how the input values are being used in such calculations to calculate the power screw efficiency in power transmission. Example Problem A vice using the square thread can withstand the maximum load of 650 Newton & torque T = 450 Nm having pitch width p = l = 4 mm. what is the efficiency of the square thread? Solution The given data load in Newton F = 650 N square thread pitch distance l = 4 mm torque T = 450 Nm Step by step calculation Formula to find η = (F x l)/(2 x π x T) substitute the values in the above formula = (650 x 4)/(2 x &pi x 450) = 0.91 Efficiency always be represented in percentage, to convert it into percentage, multiply 100 = 0.91 x 100 η = 91% In the field of power transmission by using square thread or power screw in mechanical engineering, it's important to analyse the efficiency of the mechanism. The above formula, step by step calculation & solved example problem may be useful for users to understand how the values are being used in the formula to find the efficiency of the power screw η, however, when it comes to online for quick calculations, this power screw efficiency calculator helps the user to perform & verify such mechanical engineering calculations as quick as possible.
