Abstract

Tłumik drgań, którego element sprężysty (12) ma postaci walca o średnicy wyraźnie mniejszej od wewnętrznej średnicy cylindra prowadzącego (9) i przylega podstawami do powierzchni płyty oporowej (11) i płyty ciernej (10), zamykających światło cylindra prowadzącego (9) z obu stron, których średnice odpowiadają wewnętrznej średnicy cylindra prowadzącego (9), przy czym płyta oporowa (11), element sprężysty (12) oraz płyta cierna (10) mają osiowy przelotowy otwór dla śruby (13) z nakrętką (14) napięcia wstępnego elementu sprężystego (12).A vibration damper, the elastic element (12) of which is in the form of a cylinder with a diameter significantly smaller than the inner diameter of the guide cylinder (9) and is adjacent with its bases to the surface of a support plate (11) and a friction plate (10), closing the lumen of the guide cylinder (9) on both sides, the diameters of which correspond to the inner diameter of the guide cylinder (9), wherein the support plate (11), the elastic element (12) and the friction plate (10) have an axial through hole for a screw (13) with a nut (14) of the pre-tensioning of the elastic element (12).
