connection
2. For the connection of flange A (see Fig. 5.4), use DIN EN ISO 4762
property class 10.9 hexagon socket screws of a suitable length (dependent
on the connection geometry, see Tab. 5.1).
We recommend fillister head screws DIN EN ISO 4762, blackened, smooth
headed, permitted size and shape variance in accordance with DIN ISO
4759, Part 1, product class A.
3. Fasten all screws with the specified torque (Table 5.1).
4. Now remove the eye bolt(s) used for transportation and mounting.
Keep them in a safe place for future dismounting.
5. There are relevant tapped holes on flange B for continuing the shaft train
mounting. Again use screws of property class 10.9 and tighten them with
the pre scribed torque, as specified in Tab. 5.1.
Use a threadlocker (medium strength, e.g. LOCTITE) to glue the screws into
the counter thread to exclude prestressing loss due to screw slackening, in
the event of alternating loads.
