DISMOUNTING
HSD type (see fig. 1c, page 9)
The tightening torques (TA) are indicated in table 1 (see page 9) 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 (see fig. 1d, page 9)
The tightening torques are indicated on the name plate (p) and on the dimensional 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 11).
Dismounting (see fig. 1b, page 8)
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.
