3 Installation

3.1 Transport / storage

Important: provide a lateral stop to take the

axial thrust in engaged position (see table 1).

Our clutches are supplied in packaging guaranteeing
a preservation period of 6 months with land or air

transport, or after transport by ship to neighbouring
continents (with out crossing the tropics).

3.2 Handling

Avoid any impacts on the equipment so as not
to alter their performance.

Never carry the equipment by the electrical

supply cable

3.3 Installing

E330 clutches are supplied reamed to tolerance H7
and splined to tolerance P9.

The toothed rim (350) is supplied reamed to tolerance
H7. The toothed flange (367) (size 50 to 1600) is generally
sup plied in rough form and without fixing hole.

We recommend a tolerance h6 for the shaft and H7/
f7 for the toothed rim (350) or toothed flange (367)
centering.

Important: Do not forget to stop the inductor

(101) rotating by means of a fixed part shaped in

one of the slots.

Check the play between the inductor and this part;

3.3.1 Installing VAR04

• Centre the toothed flange (367) or toothed rim (350)

on the receiving part, then fix it by bolts and lock

them

Do not forget to tighten to torque the fixing bolts for
the mov ing toothed ring (352) or moving plate (353)
and secure them with a Loctite 243 type or
equivalent product.

• After adjusting the drive keyway, fit the assembled

inductor onto the shaft and clamp it axially

It is essential when assembling the 2 parts to
respect the travel Q (measured in engaged

position - see table 1)

3.3.2 Installing VAR 504

Detection discs (aluminium or steel) compatible with
induc tive proximity sensor are provided with unit.

The position of the sensor should not obstruct the
travel of the toothed flange (349) (351).

We suggest to use the inductive sensor (615) provided
by our company, (see technical form).

MOUNTING EXAMPLE

0.5 minimum in rotation - 1 mm at base of slot

the part should not cause any strain on the

bearings.

In case of vibrations, it is strongly recommended to

insert a damping elastic slot between the
anti-rotation device and the anti-rotation slot and to

fix the coil’s cable the near est of it to avoid whipping.

In the case where two co-axial shafts are
fitted, the recommended setover is 0,05 mm
maximum.

The angular misalignment should not be greater
than 0,1 mm over a length of 100 mm. If this is the

case, use a VAR05 (flexible coupling).
