Mechanical Installation
Coupling of adapter AQ
1. Clean the motor shaft and flange surfaces of the motor and the adapter.
2. Type AQH: Unscrew the bolts of the coupling half (479) and loosen the conical connection.
3. Heat the coupling half (80 °C – 100 °C) and push it onto the motor shaft.
Version AQA / AGH: up to clearance "A" (see table).
4. Type AQH: Tighten the bolts on the coupling half in diametrically opposite sequence
(work round several times) until all bolts reach the tightening torque TA specified in
the table.
Type AQA: Use a setscrew to secure the coupling half (see table).
5. Check the position of the coupling half (clearance "A", see table).
Install the motor onto the adapter, making sure that the dogs of the two coupling
halves engage in one another. The force which must be applied when joining the two
coupling halves is dissipated after final assembly, so there is no risk of any axial load
being applied to adjacent bearings.
•
Use of the adapter AQH in a potentially explosive atmosphere is not permitted!
•
Do not insert spacer sleeves to facilitate assembly.
Only with AQA, not permitted with AQH: To avoid contact corrosion, we recommend
applying NOCO® fluid to the motor shaft before mounting the coupling half.
When mounting a motor on the adapter, use an anaerobic fluid seal to ensure that
no moisture can penetrate the adapter!
