5.3.5 Aligning the machine to the driven machine and attaching it to it (flange mounting,

vertical)

The standard flange is provided with a centering. The choice of fit for the mating flange on the

driven machine is the system manufacturer's or the plant operator's responsibility.

Note

If the machine is not fitted with a standard flange, align the machine to suit the driven machine.

Procedure

The machine axis must be vertical when it is lifted and the flange must be parallel to the mating

flange, so as to avoid seizing and stressing. Otherwise damage to the centering will result.

1. Grease the centering flange with assembly paste to make the process easier.

2. Screw in two studs into tapped holes on opposite sides of the driven machine flange. The

studs act as positioning aids.

3. Lower the machine slowly toward the driven machine and into the centering, so that the

flanges do not quite touch. Lowering too quickly risks damaging the centering.

4. If necessary, rotate the machine into the right position so that the clearance holes in the

flange are central to the tapped holes.

5. Lower the machine completely onto the mating flange so that it is fully in contact; then

remove the studs.

6. Fix the machine using the flange fixing bolts.
