    • The invention relates to a bearing assembly (1) comprising two tapered roller bearings (2, 3), each having an inner ring (4, 5), an outer ring (6, 7) and tapered rollers (8, 9) arranged between the rings, wherein the inner rings (4, 5) are mounted in or on a first machine part (10), in particular a shaft, and wherein the outer rings (6, 7) are mounted in or on a second machine part (11), in particular a housing. In order to automatically build a preload in the bearing assembly at an increased operating temperature, according to the invention the outer rings (6, 7) or the inner rings (4, 5) are arranged with a cylindrical seat (11, 12) on an adapter sleeve (14) that carries the rings and has a cylindrical counter-seat (15), wherein the one bearing ring (7) arranged on the adapter sleeve (14) is seated directly or indirectly against an axial stop (16) of the first or second machine part (10, 11), wherein the other bearing ring (6) arranged on the adapter sleeve (14) is seated against an axial stop (17) of the adapter sleeve (14), wherein the axial stop (17) of the adapter sleeve (14) is formed by a radially enlarged or reduced section (18) of the adapter sleeve (14), wherein the section (18) on the side facing away from the bearing ring (6) has an end face (19) that is located opposite an axial stop (20) on the first or second machine part (10, 11).
    • 本发明涉及一种包括两个圆锥滚子轴承(2,3)的轴承组件(1),每个圆锥滚子轴承具有内环(4,5),外环(6,7)和布置在两个圆锥滚子轴承 其中内环(4,5)安装在第一机器部件(10)中或者第一机器部件(10)上,尤其是轴上,并且其中外环(6,7)安装在第二机器部件 11),特别是一个住房。 为了在增加的工作温度下在轴承组件中自动建立预加载荷,根据本发明,外环(6,7)或内环(4,5)布置成具有圆柱形座(11,12) (14)上的适配套筒(14),其中设置在适配套筒(14)上的所述一个轴承套圈(7)直接或间接抵靠轴承座(14)的轴向止挡 所述第一机器部件或所述第二机器部件(10,11)中布置在所述适配器套筒(14)上的所述另一轴承环(6)抵靠所述适配器套筒(14)的轴向止挡部(17),其中所述轴向止挡部 (14)的径向扩大或缩小部分(18)形成适配套筒(14)的远离轴承环(6)的一侧上的部分(18)的端部 (19),其位于所述第一或第二机器部件(10,11)上的轴向止动件(20)的对面。
