Device for producing a releasable clearance-free position of a rolling bearing and a corresponding method

A device for adjusting a clearance of a rolling bearing, comprising:

• a roller bearing having an outer ring, an inner ring mounted on a shaft, and a plurality of rolling elements arranged between the inner ring and the outer ring,
• and with a tensioning device mounted on the circumference of the rolling bearing outer ring for generating a radial and uniform preload over the outer circumference of the rolling bearing outer ring,
• wherein the tensioning device has an axially adjustable tensioning element which can be brought into a first alignment in which the rolling bearing has clearance between the outer ring and the rolling elements, and which can be brought into a second alignment in which the rolling bearing is free of clearance between the outer ring and the rolling elements,
• wherein the tensioning device has a closed cavity which extends axially over the entire circumference of the tensioning device in an annular manner and tapers in the axial direction, in which cavity the tensioning element is received in the form of a sleeve in an axially displaceable manner.
