Description for selection

  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)
