Step 1
3.2.2 Motor shaft without key (straight shaft) - conical clamping unit
•
REMOVE FLANGE (3) + PINION CLAMPING UNIT (100) FROM THE GEARBOX
Loosen the screws that fix the motor flange to the gearbox housing and gently pull the flange
until the whole assembly is removed. Pay attention not to damage the gears, as this would
result in unwanted noise during operation.
•
FIT THE PINION CLAMPING UNIT (100) ON THE MOTOR SHAFT (pictures on next page)
a)
Clean both motor shaft and pinion (9) hole
b)
Oil the areas that get in touch (hole/ shaft) **
c)
Before fitting the pinion (9) on the motor shaft, slightly loosen the screws (9a) so that
they're about
2 mm
from the pinion surface, while clamper sectors (15) are in position (
X
)
d)
Insert the pinion group unit (100) with motor interface flange (03) on the motor shaft
e)
Push both pinion (100) and screws (9a) until the gearbox flange is against the motor
surface
A
. To allow clampers (15) to slide and prevent them from getting stuck, screws
heads should always be kept about
2 mm
from the pinion (9) surface and the sectors
should always be in position (
X
) during motor shaft insertion.
NOTE: some gearboxes are equipped with threaded holes for set screws (14) to help keep
the screws (9a) and the sectors (15) in the right position during motor shaft insertion:
always remove the set screws when finished.
If there are no threaded holes, make sure that the sectors are always in position (X) and do
not get stuck, by hitting them with a hammer from time to time during motor shaft
insertion.
(**)
Don’t use Molybdenum
Disulphide lubricants to prevent slipping of the clamping unit!
This assembling operation is rather delicate.
Carefully follow the procedure described below!
