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,/ d, = 0.6 and driven shaft is a solid shaft.
Take t= 100 MPa.
(b) Diameter of bolts, if the coupling uses four bolts. Take o. = 0, - 70 MPa andt= 25 MPa.
Assume pitch circle diameter as about 3 times the outside diameter of the hollow shaft.
(e) Thickness of the flange and diameter of the hub. Assume o = 100 MPa and t= 125 MPa.
(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.
