Question
Q2. Two 35 mm shafts are connected by a flanged coupling. The flanges are fitted with 6 bolts
on 125 mm bolt circle. The shafts transmit a torque of 800 N-m at 350 r.p.m. For the safe stresses
mentioned below, calculate 1. diameter of bolts; 2. thickness of flanges ; 3. key dimensions ;
4. hub length; and 5. power transmitted.
Safe shear stress for shaft materia! = 63 MPa
Safe stress for bolt material
Safe stress for cast iron coupling
= 56 MPa
= 10 MPa
Safe stress for key material
46 MPa
