ABSTRACT:
In order to be able to adjust the axial play of a shaft in a shaft holder using a universal buffer component (1) for each unit in a production series, despite a wide tolerance range within the series, a buffer component is mounted so as to be rotatable in the shaft holder (3) at right angles to the axis of the shaft (2). The buffer component (1) is further provided with a circumferential buffer surface which is eccentric with respect to its axis of rotation (4.1). This buffer surface preferably follows an Archimedean spiral and is advantageously made up of individual buffer surfaces (F1-F14). The surfaces (F1-F14) extend tangentially to the Archimedean spiral and each have a buffer region disposed at right angles to the shaft (2). The buffer region is radially set back relative to the trailing edge of the buffer surface in the direction of rotation. The length of this set back corresponds to the desired, nominal axial play ("a") to be set for the shaft (2).
