Both hydraulic jacks and screw jacks have an important structure. The important structure of hydraulic jacks is the oil tank, and the important structure of screw jacks is the screw. Today, we will mainly understand the function and maintenance of screws.

Screw is the main component used to increase torque in screw jacks, and can be said to be the "backbone" of screw jacks. It is driven to rotate by gear meshing transmission, and then the top support is gradually lifted by the rotating thread to achieve the lifting purpose.

From this perspective, the threads on the screw play a crucial role, and maintenance of these threads is crucial because the smoothness of the screw jack's ascent and descent is directly affected by the threads. If impurities infiltrate the threads or if distortion and rust occur, the top support will not be able to ascend smoothly along the screw, leading to the failure of the screw jack transmission system.

The part of the screw jack that requires the most maintenance is the screw. Lubricating the threads on the screw can effectively increase the smoothness of rotation and reduce mechanical wear, thereby ensuring the good performance of the screw jack.
