Abstract: An element for compensation of tolerances and/or gap widths of a device, having a main body which has at least one annular cross-sectional portion, wherein the cross-sectional portion has, in its peripheral direction, at least one auxetic portion which exhibits auxetic behavior in a radial direction of the main body. The invention also relates to an engine which comprises the element, to an assembly method for a shaft/hub connection which has at least one element, and to an adaptation method for adapting a tolerance and/or a gap width in the engine.

Abstract: The invention relates to an element (1) for compensation of tolerances and/or gap widths of a device, having a main body (2) which has at least one annular cross-sectional portion (3), wherein the cross-sectional portion (3) has, in its peripheral direction (4), at least one auxetic portion (5) which exhibits auxetic behavior in a radial direction (6) of the main body (2). The invention also relates to an engine (20) which comprises the element (1), to an assembly method for a shaft/hub connection (19) which has at least one element (1), and to an adaptation method for adapting a tolerance and/or a gap width in the engine (20).
