To prevent strains on the housing, fasten the gearbox only on the ange or the foot fastening
for force and torque transmission. Refer to Gearbox with foot mounting (Page486).
The second mounting option (foot or ange) is intended for add-on elements, e.g.protection
covers with an intrinsic weight of up to max.30% of the weight of the gearbox.
12.3.11 Mounting an input or output element on the gearbox shaft
WARNING
Risk of burns caused by hot parts
Do not touch the gearbox without protection.
NOTICE
Damage to shaft sealing rings caused by solvent
Avoid contact of solvent or benzine with the shaft sealing rings.
NOTICE
Damage to shaft sealing rings caused by heating
Use thermal shields to protect shaft sealing rings from heating above 100°C due to radiant
heat.
NOTICE
Premature wear or material damage due to misalignment
Misalignment caused by excessive angular or axial misalignment of the shaft ends to be joined.
Ensure precise alignment of the individual components.
NOTICE
Damage caused by improper handling
Bearings, housing, shaft and locking rings are damaged due to improper handling.
Do not use impact or knocks to mount input and output elements onto the shaft.
Note
Deburr the parts of elements to be tted in the area of the hole or keyways.
Recommendation:0.2x45°
Where couplings are to be tted in a heated condition, observe the specic operating
instructions for the coupling. Unless otherwise specied, apply the heat inductively using
a torch or in a furnace.
Use the center holes in the shaft end faces.
