Abstract
Dynamiczny tłumik drgań z nastawianą sztywnością magnetyczną, jest wyposażony w usytuowaną pionowo cylindryczną, szczelną obudowę (6), w zamku której jest zamocowana obejma nieruchoma (12) w postaci tulei kołnierzowej, której kołnierz umieszczony w obudowie (6) jest połączony rozłącznie z zamkiem obudowy (6), osadzona nieruchomo na górnym końcu wałka (13) umieszczonego w osi obudowy (6). W kołnierzu obejmy nieruchomej (12), od dołu jest zamocowany magnes pierścieniowy (4), zaś na dolnym końcu wałka (13) jest osadzona suwliwie obejma ruchoma (10) w postaci tulei kołnierzowej, której kołnierzowy koniec umieszczony w obudowie (6) jest połączony połączeniem gwintowym ze ścianką wewnętrzną obudowy (6). Drugi koniec obejmy ruchomej (10) jest wsparty na walcowej powierzchni śruby blokującej (16) wkręcanej od dołu w nagwintowany otwór wałka (13). W kołnierzu obejmy ruchomej (10), od strony obejmy nieruchomej (12), jest zamocowany magnes pierścieniowy (9). Pomiędzy obejmami (10, 12) jest osadzona przesuwnie na wałku (13) masa swobodna (7) w postaci tulei, z zachowaniem szczelin (δ) między jej czołami i czołami obu obejm (10, 12), w której czołach są zamocowane magnesy pierścieniowe (5, 8), po jednym w każdym czole. Magnesy w obejmach (10, 12) i w masie swobodnej (7) są skierowane do siebie biegunami jednoimiennymi. Między powierzchnią zewnętrzną masy swobodnej (7) i powierzchnią wewnętrzną obudowy (6) jest zachowana szczelina dylatacyjna (h).The dynamic vibration damper with adjustable magnetic stiffness is equipped with a vertically located cylindrical, tight housing (6), in the lock of which a fixed clamp (12) is mounted in the form of a flange sleeve, the collar of which located in the housing (6) is detachably connected to the housing lock. (6), fixedly mounted on the upper end of the shaft (13) located in the axis of the housing (6). In the flange of the fixed clamp (12), a ring magnet (4) is mounted from the bottom, and on the lower end of the shaft (13) there is a sliding movable clamp (10) in the form of a flange sleeve, the flange end of which placed in the housing (6) is connected threaded connection with the inner wall of the housing (6). The other end of the movable clamp (10) is supported on the cylindrical surface of the locking screw (16) screwed from below into the threaded hole of the shaft (13). A ring magnet (9) is mounted in the flange of the movable clamp (10), on the side of the fixed clamp (12). Between the clamps (10, 12) there is a free mass (7) mounted slidably on the shaft (13) in the form of a sleeve, with gaps (δ) between its faces and the faces of both clamps (10, 12), in which ring magnets are mounted. (5, 8), one in each forehead. The magnets in the clamps (10, 12) and in the free mass (7) have the same poles directed towards each other. An expansion gap (h) is maintained between the outer surface of the free mass (7) and the inner surface of the casing (6).
