Worm Gear Screw
Jack,Right Angle Gearbox,Lift Table.
Worm Gear Screw Jack
Lift systems are ruggedly designed and produced in standard models
with load handling capacities from 1/4 ton to **0 tons. They may be
used individually or in multiple arrangements. There are no
"standard" travel lengths and all Worm Gear Screw Jack Lift systems
are built to specification. Multiple Worm Gear Screw Jack Lift
systems arrangements include In-Line Configuration Worm Gear Screw
Jack Lift systems, H Configuration Worm Gear Screw Jack Lift
systems, U Configuration Worm Gear Screw Jack Lift systems, T
Configuration Worm Gear Screw Jack Lift systems.
Worm Gear
Screw Jack Lift systems parts include worm gear screw jacks, right
angle miter gearbox, jaw type and flex type couplings, linking
bars, electric motor / geared motor, When long distance between
jack and jack, extra additional pillow block bearings. For
lightweight and short stroke adjustment, manual operation Worm Gear
Screw Jack Lift systems is avaiable. Compared with pneumatic
cylinder systems, air cylinder lift systems or hydraulic table lift
system. Multiple Worm Gear Screw Jack Lift systems arrangements
have heavy duty-load capacity up to several hundreds tons, self
locking-no need brake mechanism or others locking systems,
precision positioning-easy to control according to your own design,
synchronizing lifting-multi-units uniform travel speed, easy
installation, maintenance free and long service life.

Installation Of Worm
Gear Screw Jack Lift Systems:
Direction
of rotation: Before starting installation work, the direction of
rotation of all worm gear screw jacks, right angle bevel gear boxes
and the drive motor must be checked with regard to the feed
direction of each individual worm gear screw jack.
Alignment
errors: All components must be carefully aligned during
installation. Alignment errors and stresses increase power
consumption and lead to overheating and premature wear. Before a
drive unit is attached, each worm gear screw jack should be turned
through its entire length by hand without load. Variations in the
amount of force required and/or axial marks on the outside diameter
of the screw indicate alignment errors between the worm gear screw
jack and its additional guides. In this case, the relevant mounting
bolts must be loosened and the worm gear screw jack turned through
by hand again. If the amount of force required is now constant
throughout, the appropriate components must be aligned. If not, the
alignment error must be localized by loosening additional mounting
bolts.
Test run:
The direction of rotation of the complete system and correct
operation of the limit switches must be checked again before
attaching the drive motor. In the case of translating screw jack,
check that the screw is lubricated with grease from the interior of
the gear box and re-lubricate if necessary. In the case of
travelling nut rotating screw jack, the jack screw should be coated
with suitable grease to provide lubrication for lifting operation.
The first test runs can then be carried out without load. A maximum
operating time of *0 % can not be exceeded at trial runs under
weight for worm gear screw jacks with trapezoidal
screws.
Operation: The loads,
speeds and operating conditions specified for the worm gear screw
jacks and transmission components must not be exceeded even
briefly.
Worm Gear
Screw Jack Lift Systems Application Cases In Pakistan:
Per screw
jack lift systems parts includes 4 pcs 5t travelling nut rotating
screw jacks, 2 pcs 1:1 ratio right angle bevel gear boxes, 5 pcs
linking bars, *1 pcs couplings, 4 pcs steel plates, 4 pcs flange
type pillow block ball bearings, 1 electric motor and 2 sets
forward & reversible switches and contractors.
The
linking bars, worm shafts of jacks, input & output shafts of
gear boxes, output shaft of motor must be are installed and
aligned. So all parts center height must be same, jt*5 gear boxes
are *0 mm, 1.5kw motor is *0 mm, jacks are *1.5 mm matching steel
plate thickness *8.5mm, equal to *0 mm. So the main three parts
center height is same with *0 mm. Easy to install them inline
alignment.
The screw
jack lift systems position is ***7.5x***7.5mm, included all safety
factors, max. loading capacity ***0kg, travel stroke up to ***8.5
mm, after calculation, lifting screw total length ***2.5 mm.
Lifting speed about **5 mm/min. Because lifting screw is very long,
assured the whole lift system stable for linear motions, at the top
end, extra additional 4 pcs flange type pillow block ball bearings
to fix the long lifting screws, and extra additional guiding
supports for the lift system.
