| Selection Procedure |
|
• From the continuous Power ( P ) and operating Speed ( n ) calculate the Application Torque from the formula
T norm = 9549 X ( P / n ) Nm
• Select )_Prime Mover Service Factor ( Fp ) from the table below
• Select Driven Equipment service Factor ( F m ) from page no-- 15
• The mnimum Service Factor has been set at 1.5
• Calculate Tmax from the formula--
Tmax - tnorm ( Fp + Fm )
• Select Coupling such tnat Tmax < Tnorm
• Check n < Coupling Maximum Speed ( from coupling technical data )
• Check
coupling Bore Capacity such that dmin < d max.
• Consult the factory for alternatives, if catalogue limits are exceeded.
N.B.-- If you are within 80 % of maximum speed dynamic balancing is required. |
