Stober PK - Permitted Shaft Loads for the Output Shaft

Notes
• The maximum permitted gear unit temperature (see the "Other product features" chapter) must not be
exceeded. Doing so may result in damage to the geared motor.
• For braking from full speed (for example when the power fails or when setting up the machine), note
the permitted gear unit torques (M
2acc
, M
2NOT
) in the selection tables.
8.6.2 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
2radN
= F
2rad100
; M
2kN
= M
2k100
)
• 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).
