Question
A flanged protective type coupling is required to transmit 50 kW at 2000 r.p.m.. Find:
(a) Shaft diameters if the driving shaft is hollow with d, I d, = 0.6 and driven shaft is a solid shaft.
%3D
Take t = 100 MPa.
(b) Diameter of bolts, if the coupling uses four bolts. Take o = o, = 70 MPa and t = 25 MPa.
Assume pitch circle diameter as about 3 times the outside diameter of the hollow shaft.
Thickness of the flange and diameter of the hub. Assume o.= 100 MPa and t= 125 MPa.
(c)
(d) Make a neat free hand sketch of the assembled coupling showing a longitudinal sectional elevation
with the main dimensions. The other dimensions may be assumed suitably.
