A multiflex flexible coupling, transmitting 15 kW power at 720 rpm, is shown in Fig. 9.46. It consists of two flanges keyed to the driving and driven shafts and connected together by means of a mumber of coils. The coils are placed in the slots on the periphery of the flanges at a distance of 30 mm from the axes of the shafts. The coils have a rectangular cross-section 4 x 2 mm and are made of steel FeE 220 (S, = 220 N/mm²). The factor of safety is 2.5. Calculate the required number of coils.
