5. Clamping the toothed belt 5
In the untensioned status, the strands (C) of the toothed belt 5 are lightly
arched.
• If necessary, loosen the screws 2 only so much that a relative movement
between the motor and the lower part 1 is just possible.
• Tension the toothed belt 5 slightly until both strands (C) run just parallel,
that is they are no longer curved, as follows:
With EAMM-U-50/-60/-86:
– By moving the motor by hand with the specified clamping force Fv
( Table).
With EAMM-U-110/-145:
– By moving the motor using the clamping element bD as follows:
D
• Place the clamping ele2
ment bD into the hole (D) in

the lower part 1.

• Tighten the clamping element bD with a spanner ß 8
and the recommended
torque ( Table).

• Place the additional seal aG
in the recess of the lower
part 1.
The notches of the seal aG and
the small holes in the recess
must be positioned on top of
each other.
• Attach the motor to the lower
part 1 using all the
screws 2, the seals aE and
square nuts 91).
• Tighten the screws 2 only
lightly at first to ensure that
the motor can still be moved
in the elongated hole.

With EAMM-U-110-D…-100AS1:
• Push the motor towards the
axis up to the stop.
• Only lubricate the thread and
cone of the clamping
sleeves 3/4 with
grease bC.
15980d_4
Greasing makes it easier to tighten the clamping sleeves 3/4 later and
avoids stick-slip effects.
• Insert the clamping sleeves 3/4 into the toothed belt pulleys 6.
• Lightly turn the clamping sleeves 3/4 into the thread.
• Place the toothed belt pulleys 6 on the toothed belt 5.
• Put the clamping sleeves 3/4 on the corresponding drive shafts.
• When tightening the toothed belt pulley 6, note that the surface (A) must
be aligned flush with the reference surface (B) on the lower part 1.

• Place the seal aB onto the
motor flange.
• Observe the permitted tightening torques ( Section 0).
• Clean the shafts of the motor and axis. The clamping sleeves 3 and 4
can only achieve a slip-free grip on dry and grease-free drive shafts.

Note
After each release or change in the position of the motor:
• Start a homing sequence for the axis.

Warning
Risk of injury due to uncontrolled movements of the axis!
Before assembly or disassembly:
• Make sure that the motor is de-energised.
• Observe the safety notes in the operating instructions for the motor and
axis.
• Make sure there are supplementary safety measures for applications in
which a belt failure could be the cause of an injury.

The kit is intended to connect an axis with a motor in parallel configuration
( Section 10) and fulfils protection class IP65.
When starting to tighten, the surface (A) should be about 1 mm in front of the
reference surface (B), since the toothed belt pulley 6 moves inward during
tightening by about this value.

A low pretension force is better than a high pretension force.
Excessive pretensioning of the toothed belt results in:
– impermissible radial loads/shaft break
– increased wear in the axis and motor bearings
– reduction of the service life of the toothed belt
For sizes 110 and 145:

D
Otherwise, the toothed belt 5 or toothed belt pulleys 6 will rub against the
lower part 1 or upper part 7, which in both cases will result in premature
wear or jamming.

If the tolerance is exceeded:
• Lightly loosen the clamping sleeve
• Re-adjust the toothed belt pulleys 6.

Attach the lower part 1 to the motor using all the screws 2 and seals aE.
Square nuts 9 are not required for this.

7. Mounting of the counter bearing aH … bB
Information
A counter bearing reduces the load of the axis or motor bearings to improve
the service life in the case of high loads. If the counter bearing is included
as standard, Festo considers it necessary to mount it on the axis-side to
achieve the expected service life. In all other cases, the use of a counter
bearing is also optionally possible on the axis and/or motor side

Note
Note that the transferable torque of the parallel kit is dependent on the
tightening torque of the toothed belt pulley 6:
• Select the tightening torque at the toothed belt pulley 6 between the
max. and min. value. This results in the transferable torque. It must be
greater than the max. used driving torque of the motor ( Table).
