3.3.5 Belt drive
Machines designed for belt drives are always equipped with cylindrical roller bearing in the D-
end. If a belt drive is used, make sure that the driving and the driven pulleys are correctly
aligned.
NOTE: Suitability of the shaft end and the bearings for the belt drive must be always checked
before use. Do not exceed the radial force specified in the order definitions.
3.3.6 Drain plugs
The machines are equipped with drain plugs in the lowest part of the machine. The drain plug is
constructed in such a way that it keeps the dust outside the machine and lets the condensation
water to drain out. The drain plugs should always be open, i.e. half of the plug is inside and half
of the plug is outside. The drain plug is opened by pulling it out from the frame. In AMI
machines the drain plug (M12 screw) is opened 6 - 12 mm (0.2” - 0.5”).
For horizontal machines, two drain plugs are fitted at both ends of the machine.
For vertical machines, two drain plugs are fitted to the lower end shield.
The main terminal box has one drain plug at the lowest part of the box which has to be closed
during operation.
3.4 Installation on concrete foundation
3.4.1 Scope of delivery
The machine delivery does not normally include installation, shim plates, mounting bolts,
foundation plate set or sole plate set. These are delivered according to special orders.
If new fixing holes need to be drilled, please contact ABB to ensure suitability.
3.4.2 General preparations
Before starting the installation procedure, consider the following aspects:
•
Reserve sheet steel material for shimming the machine. Possible alignment adjustments
require shims with thicknesses of 1, 0.5, 0.2, 0.1 and 0.05 mm (40, 20, 8, 4 and 2 mil)
•
Reserve a recoil hammer, adjusting screws or hydraulic jacks for axial and horizontal
adjustments
•
Reserve dial indicator gauges, or preferably a laser optical analyzer, to achieve accurate
and precise alignment of the machine
•
Reserve a simple lever arm for turning the rotor during alignment
•
With outdoor installations provide sun and rain protection to eliminate measuring errors
during installation.
NOTE: Machines are delivered with jacking screws for vertical adjustment at each foot.
