Dynamic Balancing or Two-Plane Balance of Drive Belt Pulleys
Tested by HIC
Drive belts to run at high speeds > 3,000 rpm or > 30 m/s requires dynamic balancing of belt pulley sheaves, systematic dynamic test performed on sheave balancing machine in HIC’s workshop.
Compute dynamic balancing, whether desirable, by following formula:-
RPM = 15,500 / √( D.F. )
Where, D = pulley Diameter in inches ; F = Face Width of belt pulley in inches
Resultant RPM is maximum suggested operating RPM for a belt pulley or sheave with a single plane balance.
Two-plane Balance is recommended in case belt pulley is to run at a very higher speed.
