Antifriction bearing for longitudinal displacement guidance of a gun barrel

摘要

A rolling bearing arrangement for guidance of a gun barrel during longitudinal displacement comprising a gun barrel having at least three circumferential axis-parallel strips projecting radially outward, each strip having two bearing surfaces parallel to each other and to a radial plane, which in turn are associated with directly opposite bearing surfaces extending parallel thereto in a housing surrounding the gun barrel, and a flat cage containing a set of cylindrical rollers arranged between the directly opposite bearing surfaces, the two sets of rollers cooperating with a common strip being under tension by the arrangement, displaceable in a parallel manner, by at least one element carrying a bearing surface.
