　 Generally, We choose the size of universal shaft according to transmission torque, beaning life and critical revolution speed. sometimes it is necessary to check the maximum revolution speed.

Check strength

Tc<Tn or Tc<Tf or Tc<Tp

Where:

Tc--calculated torque (N.m)

Tn--nominal torque (N.m)

Tf--fatigue torque under alternative load (N.m)

Tp--fatigue torque under pulsating load (N.m)

Determination of calculated torque Tc:

　　　　　　Tc= KT<Tn or Tf(Tp)

　　　Where:

Tc--Calculated torque (N.m)

T--Theory torque (N.m)

Pw--Driving power (KW)

n--Working revolution speed (r/min)

k--Operating status coefficient (see table)
