Document Type and Number:
Japanese Patent JP5422040
Kind Code:
B2
Abstract:
The invention relates to a bearing arrangement for supporting a shaft (3), comprising a bushing (2) in which the shaft (3) is received, a circumferential ring gap (4) being present between the bushing (2) and the shaft (3), and the bushing (2) and the shaft (3) being made of materials having different thermal expansion coefficients, a connection arrangement (21) comprising a retaining element (8; 32, 33, 34) connected to the shaft (3) and a rotating bearing ring (7) in order to provide a centering support of the bushing (2) at the outer circumference (2b) thereof relative to the shaft (3), a stationary bearing ring (6, 6′) that is disposed radially outside of the bushing (2) and forms an axial sliding bearing (14) with the rotating bearing ring (7, 7′), and is characterized in that the connection arrangement (21) comprises a circumferential annular band element (9, 9′), wherein the annular band element (9, 9′) is connected to the rotating bearing ring (7, 7′) by means of a shrinkage connection in order to form an interconnected element (23), wherein the interconnected element (23) is inserted in a recess (8a; 32a) of the retaining element (8; 32) with a centering snug fit, and the annular band element (9, 9′) is connected to the retaining element (8; 32) in the axial direction (X-X) of the shaft (3).
