SWL Series Double Input Shafts Worm Gear Screw Jack for Construction Jump Form

SWL series worm gear screw jack is a basic lifting component. The screw jack achieves the functions of up and down, propulsion, and overturning through the worm gear drives the screw. There are two movement types of screw jacks, screw movement, and nut movement. Input forms of screw jack include single-shaft input, double-shaft input, flange input, and flange plus shaft input. The screw movement type and the double-shaft input type are the basic types of screw lifters, which are widely used.

Double Input Shafts Worm Gear Screw Jack Applications:

The application scope of the worm gear screw jack includes lifting, displacement, tightening, turning, and other executive devices in the production line, tightening, lifting, and turning devices in metallurgical equipment, flexible tooling, welding lifts, and car lifts in the vehicle manufacturing industry, solar power tracking devices for monocrystalline silicon and polycrystalline silicon destined furnaces in photovoltaic industry, remote control execution devices in aerospace, national defense, astronomical telescopes, etc., lifting devices in lifting stage, various actuators of medical equipment, woodworking machinery, and food machinery, lifting devices on machine tools such as vertical lathes and gantry, as well as shipbuilding, water conservancy, papermaking, food, warehousing, casting and other industries.

Hydraulic Jack VS Screw Jack:

Worm gear screw jacks are essential components in automated machinery and usually operate in high-load applications. They are playing a more and more important role in the lifting industry.

1. Accurate positioning, self-locking after power off.

2. The system structure is simple and compact, without the need for a variety of complex pump valves, fuel tanks or gas sources, and piping systems.

3. Less noise, no fluid leakage, and little pollution to the environment are an ideal green products.

4. Due to the deceleration structure, the system can achieve small horses that use a small motor to transmit a large torque.

5. Can constitute a closed-loop servo control system to achieve automatic control.

6. Accurate and smooth delivery of force

FAQ

Q: What is the difference between a trapezoidal worm gear screw jack and a ball screw jack?
A: The trapezoidal screw jack uses a threaded acme screw that is typically self-locking, meaning it will hold its position without a brake. Ball screw jacks incorporate ball screws to convert rotary motion to linear movement. Ball screw jacks are inherently more efficient, requiring 1/3 horsepower compared to trapezoidal worm gear jacks. Due to the efficiency of a ball screw jack, a brake must be used to stop and hold a load in position.

Q: What is a Translating or Keyed-Type Screw Jack?
A: This type of jack has a key fixed to the jack housing and inserted into a keyway milled into the lifting screw which forces the screw to translate through the gearbox housing without rotating.

Q: What is a Rotating or Traveling Nut-Type Screw Jack?
A: This design incorporates a lifting screw keyed to the worm gear as a single unit, forcing the lifting screw to rotate in the gearbox, but not translate. A traveling nut, running on the rotating screw generates linear motion for the attached load. This type of jack is ideal for applications that cannot accommodate a screw protection tube.

Q: Which type of screw jack is best for a single jack system?
A: In a single jack application, with no guide rails to isolate lateral load, a Rotating or Keyed screw jack must be used. Multiple jack applications or single jack applications that are fully guided may use Translating or Keyed-Type screw jacks.

Q: Can a screw jack be operated in multiple unit systems:
A: Yes, screw jacks may be easily configured in systems, motorized and manual, to raise and lower a load in unison.

Q: Can a worm gear screw jack be operated at high speed?
A: Input power should not exceed the KW rating in specification tables. Maximum gearbox speed should not exceed 1,800 rpm.
