Function and application
A toothed belt transfers the rotary movement of a motor to a hollow shaft.
The shafts have ball bearings. The reference position of the hollow shaft can
be scanned with the aid of an inductive proximity switch in the threaded hole
6
.
The rotary module type ERMB is intended for turning work loads (e. g. with
grippers). The ERMB is not permitted for application conditions in which vegetable
and water-soluble greases or oils can penetrate into the axis. Vegetable greases or
oils can reduce the capacity of the toothed belt.
Note
The ERMB is not fitted with a brake. When the input torque is not applied,
the rotary module can be moved freely. Generally self-locking of the complete
system can be achieved with motors with integrated holding brake or with high
self-braking torque.
S
Use the motors specified in the Festo (
è
catalogue.
www.festo.com/catalogue).
You will then be operating two devices which are especially matched to each
other.
When using other motors:
S
Observe the maximum values for torques and speeds
è
chapter “12 Technical
specifications.”
S
Note the interface geometries (e.g. for the drive shafts)

Transport and storage
S
Take into account the weight of the rotary module. Depending on the design
the ERMB can weigh up to 3.3 kg.
S
Ensure storage conditions as follows:
– Storage times should be kept to a minimum
– cool, dry, shaded, corrosion-protected storage locations
