  Technical Data
Design features ( PC )
page 1 of 1
The PC construction is modular and therefore it can be as a separate unit mounted on any type of fitted geared motor (PAM),whose the various possibilities of flange/output shafts can be found on page 15. Fitting the pre-stage helical module on the main reduction unit is easily done as for any motor of type B14.The prestage unit cannot be used by itself, but only coupled with another reduction unit.
Case in aluminium alloy.
Gears : 20CrMo, machined accurately base on the accurate involute.
Coupling to electric motor
Correctly fitting the pinion on the electric motor shaft requires you keep to the following instructions:
a) Thoroughly clean the electric motor shaft.
b) Remove the motor key from its seat.
c) Fit the bush ① to the drive shaft as shown in the diagram. To make this easier, you      can heat the bush to approximately 70/80°C.
d) Fit the new key ③ provided in place of the one removed beforehand.
e) Fit the pinion ④ taking the same precautions as described in point c).
f ) Fit the washer ⑤ and tighten with the screw ⑥ .
g) Remove the rubber cap mounted on the seat of the oil seal, taking care since the      pre-stage unit is already complete with lubricant.
h) Fit the oil seal ② and then the motor assembly, taking care not to damage the lip of      the oil seal. N.B. For correct operation, with no vibration or noise, it is      recommended to use good quality motors.
