Their high
reliability, practically maintenance free designs and their
simplicity of use, render mechanical worm gear screw jacks ideal
for the most demanding and variable working conditions. They can
be used for hoisting, pulling, lining up or moving within
permissible applications. As well as being used individually,
they can be mounted in systems to offer perfect synchronization
even with unbalanced loads. Their particular construction makes
them absolutely irreversible and therefore once the input shaft
has stopped they remain in position without the need for brakes
etc., even when the load is applied to the spindle. Having a
completely machined body with double guides makes all types of
mounting arrangements possible. Applications with electric,
pneumatic and hydraulic motors are within our range.
MODELS
"TP" WITH MOVING SPINDLE.
Rotation of the driving shaft is transformed into
a straight axial displacement of the spindle by the worm wheel.
However, the spindle must have a point of reaction to stop
rotation.
"TPR" WITH ROTATING SPINDLE AND MOVING
SCREW NUT.
On this type, the spindle is keyed to the worm
wheel. Spindle rotation takes place when the input shaft
rotates. The screw nut, which is firmly coupled to the load,
causes the displacement.
END TERMINALS
In order to match different applications, various
standard end fittings are available. Special end fittings can be
manufactured on request.
SPINDLES
Standard spindles are manufactured in carbon
steel and with single start threads, as per DIN 103. They can be
supplied in a maximum length of 6 metres. Multi start threaded
and/or stainless steel spindles are available on request.
GUARDS & BELLOWS
To prevent dust and foreign bodies entering the
assemblies, various guards can be used. For type TP, there is a
steel tube at the bottom and nylon bellows at the top. For the
type TPR, only bellows are used.
OPTIONS
In addition to the basic
screw jack, the following standard options and features are
available.
CS - Screw jacks with safety lead nut
CSU - Screw jacks with safety lead nut and wear control
RG - Screw jacks with backlash control
PRF - Screw jacks with travel control
PRA - Screw jacks with reaction against rotation
PRO - Screw jacks with rigid guard protection for continuous
lubrication of the spindle
DA - Double action jacks with opposite thread directions
(left-right)
P - Jacks with rocking brackets mounted directly on the casing
SP - Jacks with supplementary mounting surface
VARIATIONS
Stainless steel spindle
Complete (casing, guides etc.) construction in Inox steel
Telescopic spindles
Special constructions for very heavy
loads, and for specific design requirements. |
