Anchor bolt
Prior to tensioning the anchor bolts, the finegrout concrete must have set for
at least 28 days.
• Keep anchor bolts in their position by tightening the nut with your fingers.
• Place the protective sleeve.
• Place hydraulic tensioning device in position.
• Initially tension the bolts alternately (for initial tensioning forces, see item 6.23).
• Using a suitable tool, screw hexagon nuts on as far as the stop.
To ensure correct handling and adjustment of the pretensioning tool, the manufacturer’s
operating instructions must be adhered to.
The tensioning pressures and/or the initial tensioning forces should be recorded (see also item 7.2.9).
6.4
Assembly of a shaftmounting gear unit with hollow shaft and parallel keyway
The end of the drivenmachine shaft (material C60+N or higher strength) must be provided with a parallel
key to DIN 6885 Part 1 Form A. Furthermore, a centring hole to DIN 332 Form DS (tapped) should be
provided (for the connection dimensions of the driven machine shaft, see dimensioned drawing in the gear
unit documentation).
6.4.1
Preparatory work
To facilitate demounting (see also item 6.4.3.), we recommend providing a connection for pressure oil on
the end of the driven machine shaft. For this a hole must be drilled through to the hollow shaft bore
(see fig. 46). This connection may also be used for supplying rustreleasing agent.
