Bevel Gear Screw Jack

Bevel Gear Screw Jack

A bevel gear screw jack is a mechanical device used to lift heavy loads and apply great forces with the use of a screw mechanism. It is widely used in various industrial applications due to its efficient and reliable nature.

What is a screw jack used for?

  • Industrial Machinery

    Screw jacks are used in various industrial machines and equipment such as conveyors, printing presses, and packaging machines to lift and move heavy loads with ease.

  • Construction and Infrastructure

    Screw jacks are used in construction and infrastructure projects such as bridges, buildings, and tunnels to provide temporary support during construction and maintenance works.

  • Agricultural Machinery

    Screw jacks are used in agricultural machinery such as tractors and harvesters to control the height of implements for better ground clearance and improved performance.

  • Metal and Steel Fabrication

    Screw jacks are used in metal and steel fabrication to provide precision control over the height and angle of cutting, welding, and assembly equipment.

  • Automotive Industry

    Screw jacks are used in the automotive industry for lifting and positioning heavy engine components and sub-assemblies during assembly and maintenance works.

What is the working principle of screw jack?

screw jack

The working principle of a screw jack is based on the simple machine of a screw. It consists of a screw mechanism that converts rotational motion into linear motion. The screw is turned manually or by a motor, which in turn moves a load-bearing nut along the length of the screw, providing linear motion to the load attached to the nut. The load is lifted or lowered by controlling the rotation of the screw.

The screw jack can be designed with different screw pitch and lead to provide different lifting speeds and load capacities. It can also be designed with different types of screws such as ball screws and acme screws to provide better efficiency and precision control.

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 uses the mechanical advantage of a screw mechanism to lift and move heavy loads while a hydraulic jack uses the pressure of a hydraulic fluid to create mechanical force.

Screw jacks are generally more efficient, reliable, and easier to maintain than hydraulic jacks. They also have a longer lifespan and can be used in harsher environments. However, hydraulic jacks can lift heavier loads and provide smoother and faster lifting action.

How to choose or customize a suitable screw jack?

  • Load Capacity

    The load capacity of the screw jack should match the weight of the load and the force required to lift it. The load capacity can be increased by using multiple screw jacks in a synchronized system.

  • Lifting Height

    The lifting height of the screw jack should match the required height of the load. The lifting height can be extended by using a telescopic screw jack or by adding extension tubes.

  • Screw Pitch and Lead

    The screw pitch and lead determine the lifting speed and load capacity of the screw jack. A lower pitch and lead provide higher load capacity but slower lifting speed.

  • Screw Type

    The screw type can be chosen based on the required efficiency and precision of the screw jack. Ball screws provide higher efficiency and precision while acme screws are more durable and cost-effective.

  • Environment

    The screw jack should be designed to withstand the environmental conditions such as temperature, humidity, and corrosion. Material selection and surface treatment are important factors to consider.
