The invention discloses a static lead screw pair internally provided with adjustable pre-pressing one-sided films for throttling, and relates to the technical field of static screw driving. The staticlead screw pair comprises a lead screw and a nut matched with the lead screw. The nut comprises an inner sleeve, an outer sleeve, adjustment devices, springs and a plurality of films, wherein the inner sleeve is matched with the outer sleeve, the adjustment devices and the springs are arranged on the inner sleeve, and the films are fixed through the inner sleeve and the outer sleeve. One end of each spring makes contact with the corresponding film, and the other end of each spring is fixed to the deep end of the corresponding adjustment device. The films are located between a groove A and a groove B. The static lead screw pair has the beneficial effects that independent work of oil cavities is achieved, and the defect of poor throttling performance caused by inconsistent gaps between theoil cavities is overcome; one-sided film throttle devices are arranged in the nut, so that the length of a sensitive oil path is decreased, and the dynamic throttling characteristic is improved; the response sensitivity of film throttling is much better than that of sliding valve throttling; and vibration of the films in work can be eliminated, so that deformation changes of the films are stable,and pressure-feedback active compensation is better achieved.
