Belt Tensioning Procedure Using A Belt Tension Indicator
- Calculate the deflection distance in mm on a basis of 16mm per metre of centre distance.
- Set the lower marker ring at the deflection distance required in mm on the lower scale.
- Set the upper marker ring against the bottom edge of the tube.
- Place the belt tension indicator on top of the belt at the centre of the span, and apply a force at the right angles to the belt deflecting it to the point where the lower marker ring is level with the top of the adjacent belt.
- Read off the force value indicated by the top edge of the marker ring.
- Compare this force to the kgf value in the table above.
- If a Belt Tension Indicator is not available, a spring balance and rule will suffice.
After the drive has been running for approximately 30 minutes, the tension should be checked and readjusted to the higher value, if necessary.
