HSD type
(fig. 1c)
The tightening torques (TA) are indicated in table 1 and on the name plate (p).
Tightening bolts are prestressed to the right level when outer ring (o) and inner
ring (n) are flush (optical check).
SD type
(fig. 1d)
The tightening torques are indicated on the name plate (p) and on the dimen-
sional drawing.
Remove spacers, attached for shipping, from between outer rings (o). When
mounting and during tightening make sure that outer faces remain parallel.
HSD + SD type
Tighten bolts (ZS) in indicated sequence (q) one by one, progressively over
several rounds, until required tightening torque (TA) is reached.
Do not tighten bolts crosswise.
Mount protection hood.
Securing in case of axial load
If the axial load is not absorbed by the shoulder of the machine shaft,
a distance ring (g) must be included (see fig. 2b, page 7).
Dismounting
(fig. 1b, page 5)
- Loosen all tightening bolts (ZS) uniformly, one by one in a continuous
sequence, about a quarter of a turn per round.
- Should outer and inner ring of the HSD-type not release themselves, one
can remove some tightening bolts and install them in tapped holes (r), in
the inner ring, to trigger separation of both rings.
- Remove shrink disc from hollow shaft.
- Mount the distance ring (g) on the hollow shaft by means of bolts (ZY)
(dimensions of ZY: see dimension drawing).
- Place the disassembly bolt (l) into the central hole in the distance ring (g).
- Remove the gear unit from the shaft by tightening the disassembly bolt (l).
Note
The parts e,f,g,l and ZY are not included as standard. They can be supplied
upon special request.
For technical data, refer to catalogue or certified drawing.
Cleaning and greasing
Dismounted shrink discs do not have to be taken apart for cleaning and
regreasing prior to reinstallation, unless they have been used in a very dirty
environment.
After cleaning, recoat the tapered surfaces using a solid lubricant with a
friction coefficient of 0,04 , e.g. Molykote D321R or similar.
