* The code refers to the purchasing of the single shrink disk. In case of purchasing a gearbox assembly KIT (flange, shrink disc and screws), please refer to the dxD dimensions to identify the shrink disc.
Gearbox assembly
■
Place the axis as shown in the figure with the gear assem-
bly component facing upwards.
■
Assemble the flange (1) on the gear and tighten the screws
(2) until the torques shown in Table 2 are reached.
■
Place the gearbox complete with flange on the unit without
locking it.
■
Insert the spacer (3) from below and then insert the Shrink
disk (4) without locking it.
■
Tighten the flange fixing screws (5).
■
Tightening sequence of the shrink disc screws:
■
Tighten the two diametrically opposite screws until the
surfaces are in contact with the shaft and hub.
■
Tighten all the screws to 50% of the value of the tighte-
ning torque indicated in Tab. 3 in a crossed sequence.
■
Repeat the same operation at 100% of the tightening
torque indicated in Tab. 3.
■
Check, in continuous sequence, that the tightening tor-
que has been reached.
■
Loosen and then tighten the gear fixing screws (5) until the
torques shown in Table 2 are reached.
