Fairloc® is a patented component fastening system
that is built into the hub of the part. How it works is
explained on page 65.
The relationship between the clamp screw fastening
torque and the torque at which the component starts
to slip on the shaft is shown in the charts. These are
typical values for stainless steel gears mounted on
stainless steel shafts.
Figure 1 shows the torque at which the sample Fairloc® gears started to slip on the shaft.
All gears and shafts were made of 303 Stainless Steel. Gear bores were within +.0003 inch of nominal values.
Shafts had surface finishes of 16 micro-inch maximum and were within –.0002 inch of the nominal diameters.
Figure 2 compares the slip torques for different values of the clamping screw fastening torques.
