Function and application

The EHMB rotation−stroke module combines two movements, rotation and stroke,
in one product. A toothed belt transfers the rotation of a motor to a hollow shaft.
The stroke of a pneumatic/electric cylinder is transferred via a connection bolt aJ
to the drive flange 1 and the grooved shaft guide 4 of the EHMB.
The shafts run in ball bearings. The reference position of the rotation can be
detected with the aid of an inductive proximity sensor in the threaded hole 6.
The position of the stroke is detected on the cylinder.
The EHMB rotation−stroke module is intended for turning and lifting work loads
(e.g. with grippers). The EHMB is not permitted for operating 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 EHMB is not fitted with a brake: When the input torque of the drive motors
is not applied, the rotation−stroke module can be moved freely. Generally
self−locking of the complete system can be achieved by the use of motors with a
spring−loaded holding brake or with high self−braking torque.
Note
Without stop nut 5 and linear drive, the shaft 4 can slip out of the seat of the
EHMB. Then a repair by Festo is required.
· If the linear drive is dismantled, make sure that the stop nut is not removed.
· Use the related motors from Festo (è catalogue specification,
www.festo.com/catalogue).
You will then be operating mating devices, which are especially adapted to
each other.
When using other motors:
· Observe the limit values for torques and speeds è chapter 12 Technical
data".
· Observe the interface geometries (e.g. for the drive shaft) è catalogue
specifications under www.festo.com/catalogue
