AI Technical Summary
Existing axial force compensation devices lack protective structures during use, resulting in poor movement of the threaded rod and easy jamming. Furthermore, the lack of internal cleaning structures leads to the accumulation of impurities on the surface of the threaded channel, causing wear.
A mechanically extended axial force compensation device with a protective component and a cleaning component was designed. The protective component stores lubricating fluid and lubricates the threaded channel through structures such as a lubrication channel, a sealing block, a sealing ring, and a filling rod. The cleaning component cleans the threaded channel through structures such as a protective shell, a moving rod, and a cleaning pad.
It effectively prevents the threaded rod from moving poorly and getting stuck, extends the service life of the device, and reduces wear and impurity accumulation in the threaded channel through its self-cleaning function.
