F. Deflection Force Comparison
Compare the actual force (F act ) necessary to deflect the installed belt at the center of the free span by
the amount calculated in step B. If the measured force (F act ) is greater than (F min ) and less than (F max ),
the drive is properly tensioned. Otherwise, adjust until the (F act ) falls between the two.
G. Dynamic Force Calculation
For new designs, it is advisable to verify dynamic loading on shafts and bearings. The general procedure
for determining these loads can be found in MPTA-B7i-2007, a publication from the Mechanical Power
Transmission Association. It may be downloaded at no charge from their website at mpta.org.
METHOD 2: SIMPLIFIED PLATINUM BELT INSTALLATION AND TENSIONING PROCEDURE
This procedure can be used for most drive installations. It provides an average tension over a range of
speeds that generally are adequate for the typical application. However, it can result in tension levels that
do not meet the needs of more demanding drives and result in shorter service live or ratcheting.
Method 1 is the preferred method and should be followed whenever possible. Refer to Appendix A for
the Method 2 procedure.
