Positioning drives with continuous hollow shaft permit the direct replacement of handwheels without mechanical modification of the spindle shaft. In this way the conversion of the manual drives to automatic positioning systems is significantly simplified.
The manual adjustment of format-dependent stations costs time in many production lines. Automatic positioning systems rectify this problem and enhance the efficiency. They also support „Industry 4.0“ requirements. The conversion does not need to be time-consuming: mounting a positioning drive with hollow shaft significantly reduces the effort required.
As is the case on the new variant of the PowerDRIVE product series. The positioning drive GEL 6113 has a hollow shaft with an inside diameter of 20 mm. With the aid of slotted double clamping rings, the dimension is reduced by up to 10 mm. Mounting on typical spindle shafts with diameters from 10 to 20 mm without mechanical modification of the spindle is possible. The engineer undertaking the conversion only needs to realise the mounting for the torque support by using a 5 mm headless screw.
The positioning drive requires only a little more space than a standard handwheel on the spindle axis. With a mounting depth of 90 mm in the axis direction, the PowerDRIVE is extremely compact. The clamping ring is already taken into account in this dimension.
The angled gear delivers nominal torques up to 10 Nm and has an absolute multiturn encoder. The robust sensor acquires the position directly at the spindle axis, as such very precise positioning is ensured.
Two lengths are available depending on the installation space. The short variant with a device length of 170 mm delivers nominal torques of 5 or 7 Nm. On the other hand the 20-mm longer device achieves a powerful 10 Nm.
The new PowerDRIVE can be connected via hybrid cable, compact M17 or robust M23 coupling. The positioning drive can be integrated directly into a plant control system via the integrated communication interfaces and the ready-to-use function blocs (PowerDRIVE-Lib).
The flexibility, particularly during the upgrading of plants, is considerably increased by the PowerDRIVE with through hollow shaft. Mounted directly on the spindle shaft without modification, the GEL 6113 saves significant conversion costs. In the end the investment pays off due to shorter, error-free format changes.
