Mounting Several Worm Gear Screw Jacks in Parallel
Requirement:
One worm gear screw jack is already installed and fastened as described in chapter 4.
1.
Bring the second worm gear screw jack into the planned position, but do not fasten it yet.
2.
If rotating screws are used, bring the travelling nuts into the same position.
3.
Push the coupling or drive shaft onto the worm gear shaft of the worm gear screw jack that is already
fastened.
4.
Push the coupling or drive shaft onto the worm gear shaft of the second worm gear screw jack.
5.
Fasten the worm gear screw jack.
6.
Repeat steps 1-5 with any other gear units.
Attention!
Check the sense of rotation of all lifting elements before assembly.
Attention!
Use torsionally flexible couplings, drive shafts or cardan shafts in order to compensate for any misalignment
of the worm gear screw jackets.
Attention!
Observe the lubricating film and screw temperature during run-in. If the screw quickly runs dry (or if there
are loud running noises with ball screws) and if the temperature is increased despite observing duty time
and permissible power, this indicates impermissible lateral forces.
