SWL Worm Gear Screw Jack

The screw jack, powered by worm gear and screw, facilitates lifting, lowering, advancing, and reversing functions, serving as a fundamental lifting component. It is widely employed across various industries such as machinery, metallurgy, hydrology, chemical, culture, and health sectors. It boasts compact structure, small size, light weight, easy installation, flexible operation, high reliability, excellent stability, and long service life. It can be driven directly by an electric motor or other power sources, or manually. This series of worm screw jacks features self-locking capabilities and high load-bearing capacity.2.5t to 120t, input speed 1500 rpm, lifting speed 2.7m/min, with various structural types and assembly methods. Working environment temperature ranges from -20 to 100°C, and lifting height is customized according to customer requirements.

Features of Screw Jack:

Smooth transmission, noiseless.

2. Low impact and vibration.

3. Suitable for low-speed applications, as well as high and low frequency scenarios.

4. Primarily for medium to light loads.

5. Maintain Load Capacity: Trapezoidal screw features an automatic locking function, which allows for the retention of load even without a braking mechanism.

6. Safety Setting: To prevent exceeding the stroke and damage to the screw and nut, a stroke switch is specially configured.

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 processes, 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 jack can be used as a single driving unit or in combination with multiple screws. The multi-screw units with mechanical synchronization are driven by a single motor, which makes them unsuitable for uneven load distribution and highly demands synchronization of lifting components. Multi-screw units with electrical synchronization have low requirements for their mechanical connection elements, but they require more complex control elements and systems. The configuration of the driving motor combined with master-slave layout can achieve corresponding synchronization of the drive system.

Once the layout is set according to your requirements, it can be confirmed.:Screwed Worm Reducers, Gear Reducers, Couplings, Connecting Shafts, and Dumbbell Glaze. The installation of the bearing housing can be related to the length and rotational speed of the connecting shaft.

Ball screw is an ideal product that converts 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 circulation structures, represented by circular and elliptical reversers.There are two types of structures: the internal circulation structure (represented by the tube) and the external circulation structure. Both of these are commonly used structures. There is no fundamental difference in their performance; 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 ten 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. They are characterized by high transmission efficiency and precise positioning.

2. When the ball screw lift mechanism serves as the actuator, the nut will convert the rotational angle of the screw into linear motion according to the corresponding pitch specifications. The passive workpiece can be connected to the nut through the nut bracket, thereby achieving the corresponding linear motion.
