The screw jack system components include: screw jacks, reducers, motors, reversing switches, drive shafts, couplings, brakes, clutches, etc. As long as the customer provides specific technical requirements, Engineers will provide detailed calculation procedures, system component selection, andCAD assembly drawing. Our technical support will be professional. A mature and reliable technical solution will ensure the safety of your equipment.

NM screw jacks can be used as a single drive unit or in a multi-screw configuration for a single lifting unit. Multi-screw units with mechanical synchronization are driven by a single motor, making them unsuitable for uneven load distribution and requiring high synchronization of lifting components. Multi-screw units with electrical synchronization have low requirements for mechanical connections but require more complex control components and systems. The configuration of the drive motor, combined with a master-slave layout, can achieve the necessary synchronization for the drive system.

Once the layout is set according to your requirements, it can be confirmed.: Worm gear reducer, gear reducer, couplings, connecting shafts, and dumbbell glaze. The installation of the bearing housing can be related to the length and speed of the connecting shaft.

ZBSeries ball screw lifters are suitable for high-speed, high-frequency, and high-performance devices.ZBSeries ball screw lifting machines are mainly composed of precision ball screw units and high-precision worm gear units, featuring high efficiency, ball friction, and improved overall efficiency with minimal driving power.Can generate a significant impetus.

Ball screw is an ideal product for converting rotary motion into linear motion, or vice versa. The structure of the ball screw lifting machine:

The structure of ball screw assemblies is traditionally divided into internal recirculation structures, represented by circular and elliptical reversers.) and the external circulation structure (represented by the pipe), both of which are commonly used structures. There is no fundamental difference in performance between the two structures; the only distinction is that the internal circulation structure has smaller installation and connection dimensions, while the external circulation structure has larger dimensions for the ball screw lifting machine. Currently, there are over 10 different structures for ball screw units, but the most commonly used ones are: internal circulation structure; external circulation structure; end cover structure; and cover plate structure.

Ball screw principle:

1. Ball screw actuators, in accordance with the national standard GB/T17587.3-1998 and application examples, are used to convert rotational motion into linear motion; or linear motion into rotational motion, featuring high transmission efficiency and precise positioning.

2. When the ball screw jack serves as the actuator, the nut converts the rotating angle of the screw into linear motion according to the specified pitch, allowing the passive workpiece to be connected to the nut bracket and nut to achieve the corresponding linear motion.

Ball screw features:

1、Ball screw vs. sliding screw, the driving torque is1/3

2、Ball screw with high precision_

3、Ball screw micro feed

4、Ball screw with zero side clearance and high rigidity

5、Ball screw high-speed feed possible.
