WHAT IS THE SIMPLE EQUATION FOR CALCULATING , HOW MUCH TENSION NEEDED FOR AN INDUSTRIAL FAN BELT(V BELT) WHICH IS DRIVEN BY MOTOR.WE HAVE THE DIAMETERS OF PULLEYS , RPM ,POWER (KW) OF MOTOR , SPAN LENGTH OF MOTOR. KINDLY GIVE ME THE TIPS...
This link provides a number of belt tension calculators. It would be wise to use specific tension range based on OEM, belt type, and service conditions.
Setting and adjusting belt tension can be by one of these three methods:
1) Elongation or stretch
2) Span deflection with spring guage
3) Sonic method for belt span natural frequency (I perfer this method)
