The clamping unit should (after loosening the tensioning screws) be loose. If not,
knock slightly on the loosened screws with a hammer in order to push back the
rear taper ring (not with K1M drive option).
Remove motor / gearbox from the hollow shaft.
ATTENTION!
Secure motor/gearbox against dropping!
Remove clamping unit (please refer to Figure 26 Pos.20a & Figure 27 Pos 20a).
Motor / gearbox mounting (ETH100&125)
The ETH100&125 electro cylinder is furnished with tensioned belt.
When mounting the gearbox / motor, the belt must NOT be detensioned or
retensioned.
Dismantle lid (please refer to Figure 26 Pos.4) and screws (please refer to Figure
26 Pos.11).
Loosen all tensioning screws of the clamping bushing (see Figure 26 Pos. 20)
(approx. 3mm) and remove them from the hollow shaft.
With K1M drive option: loosen tensioning element (please refer to Figure
27 Pos.20a) via flange sided mounting hole, do not remove tension unit. For this,
first loosen the lock screw (please refer to Figure 27 Pos. 16) and then the
adjusting screw of the tensioning element.
Clean contact surfaces of motor / gearbox shaft and hollow shaft bore.
Shaft and bores must be free of burrs, dirt and grease.
Insert motor / gearbox into hollow shaft.
with K1M drive option: insert tensioning element ((please refer to Figure
27 Pos.20) in the hollow shaft on the motor side and push up to the exterior stop.
Adjust tensioning element so that the adjusting screw can be tightened via flange
sided mounting holes.
The internal ballscrew is not self-locking!
Always take care, especially in vertical position of the ETH cylinder that the piston
rod must be safeguarded!
Secure motor/gearbox against dropping.
Eye bolts must be used with suitable lifting devices for motors and gearboxes with
eyes bolts.
Insert and tighten motor fixing screws slightly.
Insert tension bushing (please refer to Figure 26 Pos.20) into hollow shaft and
slide it up to the inner stop (not with K1M drive option).
Tighten screws crosswise until the inner ring touches the shaft and the outer ring
touches the hub (not with K1M drive option).
Tighten motor fixing screws.
Afterwards tighten tensioning screws of the clamping bushing (please refer to
Figure 26 Pos.20, please refer to Figure 27 Pos.20a) crosswise step by step (in
three turns with 1/3, 2/3 and full tightening torque), until the screw tightening
torque (please refer to Table 2) is reached.
You can apply counter pressure with the aid of a hook wrench, which can be
inserted into the bores on the toothed pulley.
Mount lid (please refer to Figure 26 Pos.4) and screws (please refer to Figure
