Question #222272
A bushed-pin type flexible coupling is used to connect two shafts and transmit 5 Kw power at 720 rpm. Shafts, keys and pins are made of commercial steel (Syt=Syc = 240 N/mm2) and the factor of safety is 3. The flonges are made of grey cast iron FG 200 (Sut = 200 N/mm2) and the factor of safety is 6. Assume, Ssy = 0.5 Syt and Ssu = 0.5 Sut. There are 4 pins. The pitch circle diameter of the pins is four times of shaft diameter. The permissible shear stress for pins is 35 N/mm2. The permissible bearing pressure for the rubber bushes is 1 N/mm2. The Key have square cross-section. Calculate,
