stainless steel screw jack On Aug.9th, we talked about how to install the screw jack.Now l’ll talk something more about the installation. That is about screw jack alignment . Screw jack has the ability to turn rotary motion into tremendous linear force, within a compact envelope, is one of the miracles of mechanics.However, properly integrating a screw jack into a specific piece of machinery is no small feat. Beyond the actual selection of the appropriate size and configuration the mounting of a screw jack takes special care. Screw jacks can take very little side load. Therefore any side forces, either from weight or misalignment, must be minimized or eliminated. This is usually accomplished by guiding the load with rails, rollers or linear bearings of some type. It keeps the load moving in the intended direction without undue strain on the nut, or internal threads in the case of a traversing spindle, from something other than the axial load it needs to move. Aligning the guides

We often say that the worm gear screw jack is divided into a trapezoidal screw lifter and ball screw jack . In contrast, these two kinds of elevators have their own advantages, but the specific use of which kind of elevator to match the working conditions depends on the requirements of the speed and load of the equipment. Of course, the accuracy of the ball screw lifter, speed and service life is higher than that of the ordinary trapezoidal screw lifter. It is better for customers with high standards to use the ball screw lifter. No matter what machinery and equipment is used, if it is used for a long time or if it is used improperly, or if it is not properly maintained, there will be some big or small problems. Today, we come to tell everyone about the common problems and solutions of ball screw jacks. Worm gear wear of ball screw jacks : The worm gear of the lift is generally made of tin bronze, and the corresponding worm material is made of 45 steel. The wear of the lift durin

When the single screw jack cannot meet the need or is very big, we think of the multiple screw jacks system. Screw Jack Systems offer comprehensive lifting and positioning design solutions for a wide variety of industries.They are suitable for heavy load and big objects. Frequently several screw jacks are required to lift a load in synchronisation.  They can be mounted in line or in a T, H or U configuration, see below picture.  In each case as single motor or geared motor is used and connection is made by spacer shaft couplings and bevel gearboxes as required. Such systems are readily possible but care is needed particularly on the dimensional layout. Coupling rotation speeds may be limited and hence a gearbox is often used to reduce the motor speed.  Ideally metal disc shaft couplings are selected because they are torsionally rigid.  In some cases jaw couplings with high stiffness may be acceptable at a lower cost.
