Abstract

Toczno-ślizgowy węzeł łożyskowy wałów maszynowych zawierający łożysko toczne i łożysko ślizgowe charakteryzuje się tym, że posiada tuleję pośredniczącą (6) i co najmniej trzy rozmieszczone po obwodzie wału (1) segmentowe obejmy (8) zawierające sprężyny (9), przy czym obejmy segmentowe (8) są połączone z tuleją pośredniczącą (6) elementami aktywnymi (7), a łożysko ślizgowe (3) podparte jest na środniku (4) wspólnej obudowy (5). Elementy aktywne (7) stanowią pierścienie. Elementy aktywne (7) wykonane są z materiału z pamięcią kształtu.The rolling-sliding bearing unit of machine shafts containing a rolling bearing and a sliding bearing is characterized by the fact that it has an intermediate sleeve (6) and at least three segment clamps (8) located around the circumference of the shaft (1), containing springs (9), and the segment clamps (8) are connected to the intermediate sleeve (6) with active elements (7), and the slide bearing (3) is supported on the web (4) of the common housing (5). The active elements (7) are rings. Active elements (7) are made of shape memory material.
