Single plate clutch transmits 25 Kw at 900rpm. The maximum pressure intensity between the plates is $85KN/m^2$ .The outer diameter of the plate is 360mm. Both sides of the plate are effective and the coefficient of friction is 0.25. - Determine the - (i) Inner diameter of the plate - (ii) Axial force to engage the clutch.

Given:

pmax = 85 kpa

R0 = 0.36m

P=25 kW

N= 900 rpm

μ= 0.25

n = 2

Solution:

Torque $= T = P/w = P \times 60/ 2πN = 25000 \times 60 / 2 π \times 900 \\ = 265.4 Nm$

T $=n \times μ \times F \times R_m …
