How to install and maintain the Screw Jack?
How to install and maintain the screw jack after you receive it? Do not worry. We have some suggestions for you.
Installation
The screw jack(no matter trapezoidal screw jack（self locking screw jack） or ball screw jack) must be installed in a manner that does not create lateral loads on the threaded spindle. If possible, use some guides to protect the jack.Great care must be taken to ensure that the threaded spindle is orthogonal to the mounting plane, and that the load and threaded spindle are on the same axis. Employing multiple screw jacks to handle the same load requires further verifications: it is critical that the load support points, (the end fittings for TP models and the lead nuts for TPR models), are perfectly aligned in order that the load can be uniformly distributed; otherwise the misaligned screw jacks would act as brake or counter-load.Whenever several jacks have to be connected by means of transmission shafts, it is recommended that they be perfectly aligned in order to avoid overloading of the worm screws. It is advisable to use joints capable of absorbing alignment errors but having, at the same time, a rigid torsion necessary to keep the synchronization of the transmission.The assembly or disassembly of the joints or pulleys of worm screw must be carried out by means of tie rods or extractors, using, if necessary, the threaded hole on top of the worm screw; striking or hammering could damage the inner bearings.For heat-shrinking joints or pulleys, we recommend a temperature between 80-100 °C. Installations environments with dust, water, vapors, etc. require precautions to protect the threaded spindle.This can be done by using elastic or rigid protections.The above protections are also used in order to avoid any accidental human contact with the moving devices.For civil applications it is always advisable to use the safety components.
Routine maintenance
The screw jack must be checked regularly, depending on the level of use and the working environment. It is advisable to check if there is a lubricant leak in the housing. If this happens, you need to find and remove the cause and fill the lubricant with the correct level.
The lubrication conditions of the threaded spindle must be checked regularly (if necessary, recovery must be made) and the presence of any foreign matter. Safety components must be inspected according to applicable specifications.
Storage
Do not let the dust and foreign matter deposits on the worm Gear Screw jacks during storage. Special attention must be paid to saline or corrosive atmospheres.
We also recommend to:
1 – Rotate the input shaft periodically to ensure lubrication of the internal parts and to avoid sealing Dry which may result in lubricant leakage.
2 – Lubricate and protect threaded spindles, worm and non-varnish components.
3 – Supports the thread spindle in the case of horizontal storage.
