OHL
= Calculated OHL on gearbox shaft [lb]
T = Load torque on shaft [lb-in]
d
0
= Pitch diameter of overhung component [in]
f
z
= Power transmission component factor
F
OHL
=
2 x T x f
z
After calculating
F
OHL
compare to the
overhung load capacity found in the tables.
F
OHL
≤ F
R
or F
R1
If
F
OHL
exceeds the rated capacity (F
R
or F
R1
) of the
speed reducer then either heavy-duty bearings
or a larger gearbox must be selected.
