Bearing device for an exhaust turbocharger, and exhaust turbocharger

Abstract

本发明涉及一种用于废气涡轮增压器的轴承装置,所述轴承装置具有第一径向轴承(8)和第二径向轴承(9),其中所述第一径向轴承(8)和所述第二径向轴承(9)构成为用于径向地支承废气涡轮增压器(1)的轴(6),其中第一径向轴承(8)具有第一轴承轴线(10)以及第二径向轴承(9)具有第二轴承轴线(11),并且其中第一轴承轴线(10)和第二轴承轴线(11)同轴地构成。根据本发明,构成有具有第三轴承轴线(14)的第三径向轴承(13),其中第三轴承轴线(14)定位成隔开一定的间距(E)平行于第一轴承轴线(10)和第二轴承轴线(11)。
The invention relates to a bearing device for an exhaust turbocharger, having a first radial bearing (8) and a second radial bearing (9). The first radial bearing (8) and the second radial bearing (9) are designed to radially support a shaft (6) of the turbocharger (1), and the first radial bearing (8) has a first bearing axis (10) and the second radial bearing (9) has a second bearing axis (11), said first bearing axis (10) and second bearing axis (11) being coaxial. According to the invention, a third radial bearing (13) with a third bearing axis (14) is provided, said third bearing axis (14) being positioned at a distance (E) to the first bearing axis (10) and to the second bearing axis (11) in a parallel manner.
