Ball screw lifter is composed of screw, nut, steel ball, pre-pressing piece, cement bulk machine reverser, dust collector, the function of ball gas filter screw is to convert rotary motion into linear motion, ball screw lifter is called column for each cycle closure, the number of lead contained within each ball cycle closure is called lap.Ball screw nut, according to the circulation way of steel ball can be divided into bent tube type, circulator type, end cap .The characteristics of these three types of loops make the ball screw jacks have a lot of balls rolling between the screw shaft and the screw nut, so they can get a high efficiency of movement.
Ball screw lifter can add pressure, because the pressure can make the axial clearance unloading device to negative values, and then get a higher rigidity, ball screw lifter by adding pressure to the ball, in the actual use of mechanical devices.Ball screw because of high efficiency of movement, so can achieve high-speed feed.Ball screw bearings to adapt to a variety of uses, to provide a wide range of standardized products.The ball screw is widely used in machine tools, the ball circulation method has circulation conduit type, circulator type, end cap type, pre-pressure method has positioning pre-pressure double nut method, bit pre-pressure method, fixed pressure pre-pressure. Ball screw lifter is a precision lifting part which uses worm vice to drive ball screw vice to lift, it has the advantages of high transmission efficiency, small volume, convenient control and smooth movement. It is widely used in the field of stage lifting, radar antenna lift mechanism, rocket, artillery launcher and construction medical.
Ball screw lifter in the process of work mainly using ball screw vice for lifting, ball screw vice does not have self-locking function, used for vertical lifting transmission system when the loss of power source, will produce reversal movement, so ball screw lift on the use of self-locking worm gear vice to achieve locking, to avoid lifting items when the screw drop. Ball screw jacks are equipped with ball screw for square box housing, ball screw has many advantages such as high transmission efficiency, high precision and long life. The life of ball screw screw jack series products is mainly determined by the life of ball screw and worm gear and other parts; we mainly calibrate the life of ball screw, worm gear will be subject to wear and tear, but the life is generally longer than ball screw.
