Question
Design a shaft and flange for
a Diesel engine in which
protected type of flange
coupling is to be adopted for
power transmission. The
following data is available
:for design
Power of engine = 75 kW;
speed of engine = 200 r.p.m.;
maximum permissible stress
in shaft = 40 MPa; maximum
%3D
%3D
permissible twist in shaft = 1°
in length of shaft equal to 30
times the diameter of shaft;
maximum torque = 1.25 x
mean torque; pitch circle
3 x
diameter of bolts
%3D
diameter of shaft; maximum
permissible stress in bolts =
.20 MPa
Find out : 1. Diameter of shaft,
2. number of bolts, and 3.
.diameter of bolts
