Stober PK - Permitted Shaft Loads for the Output Shaft

4.6.2 Permitted shaft loads for the output shaft
The values specified in the tables apply to the permitted shaft loads:
• For shaft dimensions in accordance with the catalog
• For output speeds n
2m*
≤ 100 rpm (F
2axN
= F
2ax100
; F

)
• Only if radial forces on the gear unit are stabilized by its pilots (housing, flange shaft)

You can determine the permitted radial forces from the permitted tilting torque M
2kN
and M
2k,acc
. The actual
radial forces may not exceed the permitted radial forces. The permitted radial forces pertain to the shaft
end (x2=0).

For applications with multiple axial and/or radial forces, you must add the forces as vectors.
In the event of EMERGENCY OFF operation (max. 1000 load changes), you can multiply the permitted forces
and torques for F

and M

by a factor of two.
