7. Mounting the toothed belt

15980d_4

 Move the motor in the

direction of the axis as far as
its stop.

 Grease the spring

pins 3/4 on the thread
and the outside of the cone
with lubricating grease dA.

Greased spring pins 3/4 can
be tightened evenly.

 Screw the sp ring pins 3/4 into the threads of the toothed belt

pulleys 6. Do not tighten.

 Insert the tooth ed belt pulleys 6 into the toothed belt 5.
 Place the spring pins 3/4 onto the drive shafts.

Information

The position of the surface (A) depends on the size.
50/60 70/86 110/145

15346d_9

15980d_19

 Position surfaces (A) approx. 1 mm above the reference surface (B).

Background: The tooth belt pulley 6 moves inwards when tightening.

15980d_5

 Select the required tightening torque for the toothed belt pulleys 6

( Section 10).

 Tigh ten the toothed belt pulleys 6. Apply counter pressure to the

spring pins 3/4.

Check: The surfaces (A) of the toothed belt pulleys 6 are flush with the
reference surface (B) (tolerance: ± 0.5 mm).

15980d_8

Note

 Comply with the tolerance.
If the toothed belt 5 or one of the toothed belt pulleys 6 is grinding against
the housing:

 Unscrew the sp ring pin 3/4 slightly.
 Readjust the toothed belt pulleys 6.

8. Tensioning the toothed belt

Note

A low toothed belt pretension is recommended.
Excessive toothed belt pretension can cause:
– impermissible radial loads/breaking of the shafts
– increased wear of the toothed belt 5 and the bearings of the axis and

motor.

 Avoid excessive toothed belt pretension.
The toothed belt 5 is tensioned when the strands (C) run approximately
parallel.

Untensioned: y , x Tensioned: y L 1 … 1.05 x

15. Operation

Warning

For EAMM-U-145-D100 with mounting accessories on the threads (I):
Breakouts of the screws aJ in the housing. Unexpected movement of
components. Injury due to impacts or pinching.
 Limit the feed forces of the axis:
– maximum 13 kN in the event of a dynamic tensile load
– maximum 11 kN in the event of an alternating tensile/pressure load.

Warning

Belt failure. Unexpected movement of components.
Injury due to impacts or pinching.
 Make sure there are supplementary safety measures if a belt failure could

result in injuries.

Caution

Hot surface. The motor attachment set becomes hot due to the heat
dissipation of the motor. Injury due to burns.

 Avoid contact withou t suitable gloves.
 Let the motor attachment set before mounting work.

16. Maintenance

The toothed belt 5 is a wearing part ( www.festo.com/spareparts).
 Check the toothed belt 5 at regular intervals:
– during maintenance of the machine
– when replacing an axis.

 Replace the toothed belt 5 at the following indicators of wear:
– excessive accumulation of wear particles in the housing
– cracks on the back of the toothed belt
– visible glass fibre cords in the tooth base.

Caution

For EAMM-U-145-D100 with mounting accessories on the threads (I) and with
use of axis ESBF in the high-load range (, 50 % of the maximum ESBF feed
force):
Breakouts of the screws aJ in the housing. Unexpected movement of
components. Injury due to impacts, shocks, or pinching.
 Replace the axis and parallel kit at the same time.

The service life of the components is comparable with one another.
