The alignment of the complete drive packages mounted on a bedplate has been carefully
checked before shipment. It is nevertheless required to check that the bedplate has not been
deformed during transport or erection. Therefore check again alignment of couplings or other
elements after final installation.
5.5 SECURING OF HOLLOW SHAFT GEAR UNITS
5.5.1 Hollow shaft gear unit with shrink disc connection
The HANSEN supplied shrink disc is ready to be installed.
Therefore do not dismantle shrink disc prior to first mounting.
The HSD-type is used as standard.
Upon request the SD-type is possible.
Mounting (see fig. 1a)
- Clean and degrease contact surfaces (a) and (b)
- Smear surface (b) - and not surface (a) - with "Molykote D321R" or similar.
- After the applied coating has hardened, slide the O-ring (c) onto the shaft.
- Draw the gear unit onto the shaft of the machine using threaded rod (e), nut (f) and
distance ring (g) until faces (h) and (i) make contact.
- Fit shrink disc (s). A locating groove on the shaft indicates the position of the shrink disc.
Tighten bolts (ZS) with a torque wrench. The required tightening torque for the HSD-type
is shown in table 1 (page 9).
For the SD-type it can be found on the dimensional drawing.
NOTE: Never tighten bolts when shrink disc is unmounted.
