Stober PK - Permitted Shaft Loads for the Output Shaft

5.6.2 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*
≤ 20 rpm (F
2axN
= F
2ax20
; F
2radN
= F
2rad20
; M
2kN
= M
2k20
)
• Only if radial forces on the gear unit are stabilized by its pilots for the pitch circle diameter and flange
housing design

The specified values for F
2rad20
and F

refer to an application of force at the center of the output shaft: x

= l/2.
Shaft dimensions can be found in the "Dimensional drawings" chapter.

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
2ax20
, F
2rad20
and M
2k20
by a factor of two.
