Coupling Notes and Data - Mechanical Design Data Manual & Notes - 3rd Ed; (Chapter 5 - Couplings)
Assignment
1. The machine given in the example in the notes (p94) is working OK.
Now you are looking at building another machine with much
more output - the power is now 30kW. The torque is increased
by 4 times, so the shafts will be larger of course. The motor is a
flange mounted motor (select here),
from which you can determine the shaft size. The diameters of the motor
and driven shafts are the same. Everything else is the same as previous
design (as per the example in the notes).
