Stober PK - 10.6.2 Permitted Shaft Loads for the Output Shaft

10.6.2 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

= F
2ax20
; F

)
• Only if radial forces on the gear unit are stabilized by its pilots for the pitch circle diameter and flange

For the V solid shaft design on both sides, the values for F
2rad20
and M
2k20
must be multiplied by a factor of
0.7.
