Fastening using IM B5 or IM B14 flanges:
a)
Remove the anti-rust varnish: First of all, clean the surface of the flange before fastening.
b)
Connect and fastened the counter-flange: For correct fastening, use bolts with an appropriate diameter in accordance
with the dimensions of the flange as per the EN 60072 standard.
c)
Make sure of the perpendicularity of the machine shaft and the counter-flange plane: Perpendicularity errors must be
below 0.05 mm.
d)
Make sure that the counter-flange is appropriate: In accordance with section b) of the IM B3 assembly.
NB
Application of additional loads on the flange
The motor flange is dimensioned only to support its own weight. If there are additional loads, the flange may not be sufficiently
heavy duty and, therefore, faults may occur that affect the motor and the machine to which it is coupled.
Machine coupling
5.1.3
The motor must be coupled to the machine very carefully since it is fundamental in order to ensure the correct service life of the
motor.
Before mounting the coupling, remove the protective lacquer and clean the surface well.
PRECAUTION
Damages to the motor bearings
Prevent solvent from entering the interior of the bearings since they could be damaged.
If the motor works with a direct drive (coupled directly to the load), the appropriate coupling must be used to compensate the
alignment errors and radial forces that are applied. Please check with VASCAT in case of doubt.
In any case, make sure that the alignment between the motor shaft and that of the machine corresponds to the coupling between
both parts.
PRECAUTION
Damages to the shaft and bearings
Excessive misalignment can cause overloads on the bearings and break the shaft or cause the bearings to seize up through
fatigue. The customer is responsible for ensuring the correct alignment of both shafts.
VASCAT motors and rotors are dynamically balanced using a half-key on the end of the shaft (in accordance with the 60034-14
standard). To ensure the correct balance of the entire transmission unit, all the parts of the transmission system must also be
balanced (pulley, coupling, etc.).
The installation of the coupling or the transmission element must be made gently without knocking, previously heating the pulley
or using an appropriate tool (please see Figure 8).
