Dismounting
Danger!
Loose drive components or drive components falling down may cause
injury to persons or damage to the machine. Secure the drive
components
before
disassembly.
1. Remove protective cap (1).
2. Loosen clamping screws (2) evenly one after the other each by ¼ revolution in
several passes. Do not unscrew clamping screws completely to prevent accidents!
3. Press off outer ring (see Fig. 15), if necessary. For this, loosen the outer ring using
the forcing threads and some clamping screws (number corresponding to the
forcing threads in the inner ring). For loosening the outer ring, screw in the screws
evenly to prevent canting. Press off the outer ring until loosened completely.
4. Remove the drive from the machine shaft.
Stop!
Dismantle the shrink disc
only
for cleaning purposes. Afterwards, grease
bevel surfaces and screws using a solid lubricant with a friction factor of
m
= 0.04.

Suitable lubricants on molybdenum−disulphide lubricant (MoS2) basis are, e.g.:
–
Molykote G Rapid (company Dow Corning)
–
Molykote BR2 Plus (company Dow Corning)
–
Molykombin UMFT1 (company Klüber Lubrication)
Usually, disassembly problems only occur if:
¯
the connection is spinning due to overload or a too low friction factor and fretting
corrosion has occurred,
¯
the shrink disc has been tightened too much leading to a plastic deformation of
components,
¯
the components are corroded.
