Bearing arrangement
A bearing arrangement with at least one inner ring ( 1, 2 ) and a first outer ring ( 4 ) arranged coaxial to the inner ring is provided, wherein the outer contours ( 15 ) of the at least one inner ring ( 1, 2 ) and the inner contours ( 10 ) of the first outer ring ( 4 ) form a number of bearing receptacles ( 30 ), which have conical raceways and axes of symmetry ( 17 ) inclined to a main axis ( 23 ) of the at least one inner ring ( 1, 2 ) or the first outer ring ( 4 ).
1 . Bearing arrangement, comprising at least one inner ring ( 1 , 2 ) and a first outer ring ( 4 ) arranged coaxial to the at least one inner ring, wherein outer contours ( 15 ) of the at least one inner ring ( 1 , 2 ) and inner contours ( 10 ) of the first outer ring ( 4 ) form a number of bearing receptacles ( 30 ), which have conical raceways and axes of symmetry ( 17 ) inclined to a main axis ( 23 ) of the at least one inner ring ( 1 , 2 ) or the first outer ring ( 4 ).
2 . Bearing arrangement according to claim 1 , further comprising a number of axial tapered rollers ( 3 ) in contact with the at least one inner ring ( 1 , 2 ) and the first outer ring ( 4 ) via the raceways, the axial tapered rollers are formed for transfer of an axial load between the at least one inner ring ( 1 , 2 ) and the first outer ring ( 4 ).
3 . Bearing arrangement according to claim 1 , wherein a plurality of inner rings ( 1 , 2 ) are arranged axially one next to the other.
4 . Bearing arrangement according to claim 3 , wherein each of the inner rings ( 1 , 2 ) has an axial end surface ( 13 ), through which an axial load from an axially adjacent shoulder of an axially adjacent functional module can be transferred into the inner ring ( 1 ).
5 . Bearing arrangement according to claim 1 , wherein the contours of the first outer ring ( 4 ) have a number of bearing surfaces ( 10 ) formed from hardened and/or ground bearing steel for defining the raceways of the bearing receptacles ( 30 ).
6 . Bearing arrangement according to claim 2 , wherein the first outer ring ( 4 ) has a number of raceway flanges ( 11 ) for positioning and/or guiding the axial tapered rollers ( 3 ).
7 . Bearing arrangement according to claim 1 , wherein the first outer ring ( 4 ) has an axial end surface ( 9 ), and a main axial load can be transferred between the end surface ( 9 ) and a load-bearing shoulder of an engine housing.
8 . Bearing arrangement according to claim 1 , wherein the contours of the at least one inner ring ( 1 , 2 ) have several bearing surfaces ( 15 ) formed from hardened and/or ground bearing steel, for defining the raceways of the bearing receptacles ( 30 ).
9 . Bearing arrangement according to claim 1 , further comprising a second outer ring ( 6 ), which is formed for receiving an axial load directed opposite a main axial load.
10 . Bearing arrangement according to claim 9 , wherein the first outer ring ( 4 ) and the second outer ring ( 6 ) are fixed to each other by a band with a slot or a clip ( 5 ).
11 . Bearing arrangement according to claim 9 , wherein inner contours ( 21 ) of the second outer ring ( 6 ) and outer contours ( 12 ) of an adjacent inner ring ( 2 ) form raceways for ball bearings ( 7 ).
12 . Bearing arrangement according to claim 11 , wherein the inner contours ( 21 ) of the second outer ring ( 6 ) form bearing receptacles with conical raceways, in which axial tapered rollers are held, rotational axes of the axial tapered rollers are inclined to a main axis of the inner ring or the second outer ring ( 6 ) and are inclined opposite the axes of symmetry ( 17 ) with regard to the main axis ( 23 ), with the outer contours of the adjacent inner ring ( 2 ).
13 . Bearing arrangement according to claim 1 , wherein the bearing arrangement is installed in a drilling engine.
