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

A device for producing a releasable clearance-free position 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 between the tensioning device and 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 play, and which can be brought into a second alignment in which the rolling bearing is free of play,
• wherein the tensioning device has a closed cavity which extends axially and at least in sections, preferably 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.
