Function and application

An internal actuator converts the rotary movement of a motor into a linear
movement. The actuator moves the internal slide backwards and forwards.
Design of the actuator:
DGE−...−ZR: Rotating toothed belt
DGE−...−SP: Rotating spindle
Through a fixed connection, the driver also moves. The slot in the cylinder barrel
required for this is covered by a band system. With the DGE−...−KF designs a slide is
fastened to the driver. The slide has its own guide.
The DGE is intended for exact positioning of
masses. It is approved for operation in slide
mode and yoke mode (cantilever mode).
Designs with toothed belt (DGE−...−ZR) are not
permitted for application conditions in which
vegetable and water−soluble greases or oils
can penetrate into the axis.
Note
The DGE linear axis is not automatic locking: When input torque is not applied,
the slide can be moved freely. Generally, a latching function of the complete
system can be achieved with motors with an integrated holding brake or other
suitable means, such as clamping systems, motors with high gear ratios or
automatic−locking gear units. Which measure is appropriate to select basically
depends on the application and the safety requirements.
· Please select the appropriate motors from our catalogue

You will then be operating mating devices which are especially adapted to
each other.
· Observe the limit values for forces, torque and speeds
