Motorized Worm Gear Screw Jack: Everything You Need to Know

If you are in the manufacturing industry, you might have heard of the motorized worm gear screw jack. This device is widely used in various industrial applications because of its versatility, durability, and efficiency. In this article, we will discuss everything you need to know about motorized worm gear screw jack, its uses, working principle, and how to choose the right one for your needs.

What is a Screw Jack Used for?

Screw jacks are used to lift heavy loads vertically or to push them horizontally. They are commonly used in manufacturing, construction, and transportation industries to lift heavy equipment, machines, or vehicles. Here are some of the common uses of screw jacks:

  • Adjustment of workpiece height in machine tools
  • Positioning of material in welding, cutting, and assembly operations
  • Adjustment of conveyor belts in material handling systems
  • Lifting and lowering of stages, platforms, and lighting rigs in the entertainment industry
  • Leveling of buildings, bridges, and other structures

What is the Working Principle of Screw Jack?

The working principle of screw jack is based on the simple machine called the inclined plane. It consists of a worm screw and a worm gear that mesh together. When the worm gear is rotated, it causes the worm screw to move axially, which in turn causes the load to move vertically or horizontally.

The efficiency of the screw jack depends on the angle of the thread, the pitch of the thread, and the number of threads. The higher the angle, the higher the efficiency; the smaller the pitch, the higher the load-bearing capacity; and the more the number of threads, the higher the speed of lifting or lowering.

What is the Difference Between a Screw Jack and a Hydraulic Jack?

The main difference between a screw jack and a hydraulic jack is the method of operation. A screw jack is operated by a motor that rotates the worm gear, while a hydraulic jack is operated by hydraulic pressure.

Screw jacks are more suitable for applications that require precise positioning and heavy load-carrying capacity, whereas hydraulic jacks are more suitable for applications that require rapid lifting and lowering.

How to Choose or Customize the Right Screw Jack?

When selecting or customizing a screw jack, you need to consider several factors such as load capacity, lifting speed, travel distance, duty cycle, and environmental conditions. Here are some of the factors in detail:

  • Load Capacity: The load capacity of a screw jack should be sufficient to lift or push the load. You should consider both static and dynamic loads, as well as the safety factor.
  • Lifting Speed: The lifting speed of a screw jack should be appropriate for the application. You should consider the duty cycle and the required lifting speed.
  • Travel Distance: The travel distance of a screw jack should be sufficient to reach the desired height or position. You should consider the length of the screw and the number of threads.
  • Duty Cycle: The duty cycle of a screw jack should match the application. You should consider the frequency and duration of use.
  • Environmental Conditions: The environmental conditions of the application should be considered. You should consider the temperature, humidity, corrosion, and other factors that may affect the performance of the screw jack.
