Flexible couplings solve problems due to alignment and centring of shafts. Moreover, flexible couplings facilitate assembly by providing a tolerance of 2º when aligning and centring the shaft over the gearbox fixing plate. SELECTION EXAMPLE P' = Engine Power = 40 CV N = maximum engine rpm = 3000 rpm R = Gearbox reduction ratio = 2:1 = 2 N' = Shaft Revolutions = N/R = 3000/2 = 1500 rpm P = Coupling Permissible Power P=(N'/100)x f --> P>P' Our engine has an SMI-R3 (ØD=63.5) gearbox, so we look in the catalogue for a coupling that fits the gearbox flange's. We choose the 40025100 and determine its admissible power P. P = (1500/100)x3 = 45CV > 40CV --> CORRECT
