1 Clamping ring hub
2 Clamping ring
3 Clamping screws (DIN912)
Note!
The motor shaft must be designed with fit k6.
1. Grease the contact surfaces of the motor shaft using a thin-bodied oil, e. g.
“Castrol 4 in 1” or “Klüber Quitsch Ex”!
Stop!
Do not use oil or grease with molybdenum-disulphide or high-pressure
additives, or grease pastes!
2. Push the coupling hub over the motor shaft, mounting dimension “m” (see Fig. 3
and Tab. 3) must be observed.
3. Align the hub and tighten the clamping screws until they have contact.
4. Tighten the clamping screws evenly and crosswise with gradually rising torque
until the indicated tightening torque (see Tab. 3) is reached at all clamping screws.
In the intermediate steps, this procedure should also be repeated until the
indicated tightening torque is reached at all clamping screws.
5. Lay spider in the coupling claw on the gearbox side.
6. Align claws of the motor-side coupling hub with its counterpart.
7. Slowly push on motor, and bolt on to the gearbox flange.
