A device for concentrically positioning a first part relative to another part, in particular a sleeve relative to a shaft

摘要

An arrangement for concentrically positioning a first part relative to a second part, e.g. a sleeve (2) relative to a shaft (1), where the parts consist of materials of different coefficients of thermal expansion, provides a radial clearance (4) between the two parts (1, 2). The first part (2) is furthermore supported, along areas facing away from the second part (1) in the radial direction, against an abutment arrangement (7, 8) with the same or similar thermal expansion properties to those of the first part (2). The abutment arrangement (7, 8) is held concentrically relative to the second part (1). IMAGE
