Check for proper sheave or pulley alignment. If the sheaves are misaligned, it will cause premature belt wear, excessive belt noise, and vibration. Check the alignment by placing a straight edge along the outside face of both sheaves. Misalignment appears as a gap between the outside face of the sheaves and the straight edge. Align sheaves to eliminate the gap by adjusting the pump or the motor to make the shafts parallel. Check for “tilting” of the pulleys with a bubble level. Belts must be properly tensioned initially then rechecked periodically. The ideal tension for a V-belt is the lowest tension at which the belt will not slip at the highest load condition. With all belts in their grooves, adjust centers to take up the slack until they are fairly taut. Start the drive and continue to adjust until the belts have only a slight bow on the slack side while operating with load conditions.
hello sir, can u please tell what is shim calculation formulA?
Greetings,
Well Explained Sahim Khan.
I have a question, How do we align v belts in the refer compressor?
