GEARBOXES V-DRIVE
The advice given in the preceeding paragraph are also valid in this case. If the gearbox is installed
separately, it is necessary to use a universal joint with variable lenght. To make the joint work in the
best conditions (omokinetic transmission) and to avoid damaging the gearbox or the motor, it is neces-
sary to respect some rules for the installation, as indicated in the following schemes.
ALIGNMENT METHOD WITH PARALLEL FACES FLANGES
The motor and the gearbox must be installed so that flanges A and B are parallel.
1 Motor
2 Flexible coupling
3 Universal joint with variable lenght.
– Selected in accordance with the manu-
facturer advice.
– In compliance with the instructions for the
installation.
4 Propeller axle.
5 Marine gearbox with input and output on the
same face.
Make sure the longitudinal axis of the flexible
coupling, the universal joint and the gearbox
input shaft are aligned on the same vertical plane.
ALIGNMENT METHOD WITH COUNTERPOINT SHAFTS
1 Motor
2 Gearbox
3 Universal joint with variable lenght.
– Selected in accordance with the manu-
facturer advice.
– In compliance with the instructions for the
installation.
4 Propeller axle.
To facilitate the correct alignment of the motor
and the gearbox, that is to say to obtain iden-
tical connecting angles: ß1 and ß2:
– install two alignment shafts 6 instead of
the universal joint;
– the shafts must have the same lenght;
– align the two units so that the heads of
the shafts meets each other, to ensure
the angles identity (ß1 and ß2);
– then remove the alignment shafts and
install the universal joint;
– make sure the longitudinal axis of the
flexible coupling, the gearbox alignment and input shafts are aligned on the same vertical plane.
