A leader faced conical clutch has a cone angle of $30^0$ . If the intensity of pressure between the contact surfaces is limited to $0.35 N/mm^2$ and the breadth of the conical surfaces is not to exceed one-third of the mean radius, find the dimensions of the contact surfaces to transmit 22.5 KW at 2000rpm. Assume uniform rate of wear and take coefficient of friction as 0.15. -

Given:

Θ=30

Semicone angle = α = 30/2 = 15

pmax = 0.35 Mpa

B=Rm/3

P=22.5 kW

N= 2000 rpm

μ= 0.15

Solution:

Torque $= T = P/w = P \times 60/ 2πN = 22500 \times 60 / 2 π \times 2000 \\ = …
