Patent number: 10508564Abstract: A bearing housing for an exhaust gas turbocharger may include a bearing housing cover arranged on a bearing housing wall. The bearing housing cover may include a penetrating rotation-symmetrical sealing recess with a centre axis and may have a locating surface facing the bearing housing wall and radially extending from the centre axis. The bearing housing may include a sealing bush arranged in at least one region of the sealing recess. The sealing bush may have a stop surface arranged opposite the locating surface and may include a penetrating shaft recess disposed rotation-symmetrical relative to the centre axis. The bearing housing cover may further include an at least partly circulating groove disposed on the locating surface radially spaced from the centre axis. The groove may include a drainage region arranged below the centre axis and extending from the centre axis radially to an outside.Type: GrantFiled: February 19, 2018Date of Patent: December 17, 2019Assignee: BMTS TECHNOLOGY GMBH & CO.Inventors: Fabian Haslinger, Simon Henzler, Ruediger Kleinschmidt, Oliver Kuhne, Steffen Schmitt, Frieder Stetter

Patent number: 9719557Abstract: A bearing for an exhaust gas turbocharger may include an annular body and a centrally arranged passage opening for bearing a shaft at least one of axially and radially with respect to a rotation axis. The body may include an oil pocket, a wedge surface extending at least partially in a circumferential direction, and a detent surface circumferentially spaced from the oil pocket via the wedge surface. The detent surface may include a predetermined wear height configured to be worn down over an operating lifespan of the bearing. A radially inner flange may extend at least partially along the wedge surface in the circumferential direction and define an inner sealing web. A radially outer flange may extend at least partially along the wedge surface in the circumferential direction and define an outer sealing web.Type: GrantFiled: July 9, 2015Date of Patent: August 1, 2017Assignee: Bosch Mahle Turbo Systems GmbH & Co.

Patent number: 9719558Abstract: A bearing for a turbocharger may include an annular body and a centrally arranged passage opening for bearing a shaft at least one of axially and radially with respect to a rotation axis. The body may include at least one segment extending at least partially about the passage opening in a circumferential direction. The at least one segment may include an oil pocket, a circumferentially extending wedge surface and a detent surface circumferentially spaced from the oil pocket. The segment may also include a radially inner flange extending at least partially along the wedge surface in the circumferential direction. The inner flange may define an inner sealing web that may continue uninterruptedly into the detent surface.Type: GrantFiled: July 9, 2015Date of Patent: August 1, 2017Assignee: Bosch Mahle Turbo Systems GmbH & Co.
