Technical Data  Linear actuator  Linispeed Jack  Allowable overhang load

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.

Allowable O. H. L. ≧ T×f×Lf R

O.H.L.:Overhang load N

T:Input torque N・m

f:Transmission element factor

Lf:Factor by load acting position

R:Pitch circle radius of sprocket, gear, V pulley m

Overhang load

L:Load acting position

Q:Length of shaft

Table 2 Transmission element factor (f)

Chain 1.00
Gear, toothed belt 1.25
V-Belt 1.50
Flat belt 2.50
