MAIN HEADING FLEXIBLE SHAFT & SPLIT HALF COUPLINGS

FLEXIBLE SHAFT COUPLINGS

Contoured flexible disc moulded in tough Polyester Elastomer. Gives clearance for bolt heads, and is able to flex freely to take up any temporary misalignment of the engine and shaft, due to flexing of the boat structure or the engine moving on its rubber vibration isolation mountings. • For engines 5 to 1500 HP. • Reduces engine noise and vibration transmission. • Fail safe design. • Bolts between existing shaft flanges. • Requires no machining. • Simple to install. • Simple to periodically check alignment. • Accepts propeller thrust. • Impervious to salt water, diesel and lubrication oils. • Electrical continuity available. HOW TO SELECT 1. Engine horse power and engine speed. 2. Gearbox type and reduction ratio. 3. Gearbox flange details, diameter of flange, diameter of register, pitch circle diameter of fixing holes, size and quantity of holes. (Pitch circle diameter is the distance between the centre of hole at 12 o’clock position to the centre of the hole at 6 o’clock).

Example: 1. Ford 150 HP at 2500 RPM

Horse power of engine x reduction ratio x 100 = HP/100rpm Engine Speed 150 x 2 x 100 = 12HP/100rpm 2500 2. Borg Warner Velvet Drive 72C 2:1 Reduction 3. 5" Flange, 2.500 dia Register, 4.250 PCD, 4 off holes 0.437 diameter To calculate Power of coupling required.
