Опора состоит из установленны.х на валу и в корпусе дуплекса подшипников. .Между наружными и внутренними кольцами подшипников установлены упругие элементы в виде пружин щих шайб. Наружное кольцо одного и внутреннее кольцо другого подшипника имеют возможность осевого перемещени . При нагружении дуплекса осева  сила распредел етс  между подшипниками пр мо пропорционально жесткости ука- .uiHHbix упруги.ч элементов. 1 ил.The invention relates to mechanical engineering. The goal is to improve the accuracy of the axial load distribution between the onory bearings. The support consists of installed x on the shaft and in the housing of the duplex bearings. . Between the outer and inner rings of the bearings there are installed elastic elements in the form of spring washers. The outer ring of one and the inner ring of the other bearing have the possibility of axial movement. When the duplex is loaded, the axial force is distributed between the bearings in direct proportion to the stiffness of the elastic elastic elements. 1 il.
