5.4.1 Assembling the coupling5.4 Couplings
Introduction
The method used to assemble the coupling varies according to type. The procedure de-
scribed in these operating instructions is general rather than specific to one type of coupling.
Assemble the coupling as described in the operating instructions for the specific coupling.
Improper use can damage the gear unit. Be sure to take the following precautions:
• Do not use force (hammer blows, etc.) to fit the coupling parts as this can cause internal
damage to the gear unit.
• Take care not to damage the shaft sealing rings or shaft running surfaces when fitting
the coupling parts.
Procedure
To fit the coupling, proceed as follows:
1. Carefully clean the shaft ends and the coupling parts.
2. Use a suitable fixture to mount the coupling parts on the shaft ends.
3. Lock the coupling parts to prevent axial displacement.
4. Move the machines to be coupled close to one another and thenalign them (Page71).
5. Join the coupling parts together.
Heating coupling parts prior to mounting
Depending on the order specification, it may be necessary to heat the coupling parts before
mounting them.
WARNING
Risk of burns
Possible risk of serious burn injury from hot surfaces (>55°C).
Wear suitable protective gloves and protective clothing.
Improper use can damage the gear unit. Be sure to take the following precautions:
• The required joining temperatures can be found in the dimension drawings in the operat-
ing instructions for the coupling
• Unless otherwise instructed, heat the coupling parts by an induction heater, with a torch
or in an oven.
• Use heat shields designed to protect against radiant heat in order to safeguard the shaft
sealing rings against damage or heating to above 100°C.
• Quickly fit the coupling parts on the shafts. You will find the mounting dimensions in the
dimension drawings in the operating instructions for the coupling.
Gear units with hollow output shaft or flanged output shaft
There is no need to install the output-side coupling for gear units with a hollow output shaft
or flanged output shaft.
