What are the characteristics of screw lifter?

Today's screw elevator, do you understand its characteristics? I believe that most of my friends are not so familiar with this aspect, so please follow the lead screw elevator Xiaobian to understand it well.

Screw elevator is also known as screw elevator. It is mainly used to transform rotary motion into linear motion or linear motion into rotary motion. There are mainly to transfer weight, such as screw press, Jack, etc.; there are mainly to transfer movement, such as feed screw of machine tool workbench; and screw transmission mechanism to adjust the relative position of parts.

It can be used alone or in combination. It can accurately control and adjust the lifting or pushing height according to a certain procedure. It can be directly driven by electric motor or other power, or can be manually driven. It has different structural forms and assembly forms, and the lifting height can be customized according to the requirements of users.

Screw lifter has sliding friction mechanism and rolling friction mechanism.

The sliding screw nut mechanism has the advantages of simple structure, convenient processing, low manufacturing cost and self-locking function, but it has large friction torque and low transmission efficiency (30% - 40%).

Although the ball screw nut mechanism has complex structure, high manufacturing cost and can not completely self-locking, its advantages are small friction resistance moment, high transmission efficiency (92% - 98%), high precision, good system stiffness, reversible movement and long service life.

Screw elevator is a kind of basic lifting components, which is widely used in all walks of life.

The structural design of screw elevator is stable, which can play a more stable and safe effect in the use process. The installation design is more simple to meet the use requirements of different environments. It is widely used in the industrial production environment, and the processing cost is particularly low. Naturally, it can reduce the production and processing costs of enterprises and improve the profitability.
