Allowable overhang load
When installing a sprocket, gear, or belt on the input shaft, use the following formula to verify that any overhang load applied to the shaft falls within the allowable OHL (Table 1).
Allowable O. H. L. ≧ T×f×Lf R
O.H.L.：Overhang load N{kgf}
T：Input torque N・m{kgf・m}
f：Transmission element factor
Lf：Factor by load acting position
R：Pitch circle radius of sprocket, gear, V pulley m
