Abstract
A play-free rotary mounting for a drive roll held on stop surfaces in the axial direction on a cylindrical body, wherein V-shaped annular grooves with an opening angle V are provided at least in one of the end faces of the drive roll and the stop surface located opposite them on the body, V-shaped bearing shells with at approximately identical opening angles and approximately identical leg length are inserted into the annular grooves, the vertex diameters of the annular grooves differ from the vertex diameters of the bearing shells. Balls with a diameter matched to the opening width of the bearing shells are inserted into the bearing shells. At least one of the stop surfaces can be adjusted in the axial direction in order to clamp the drive roll in. Instead of different vertex diameters, different opening angles can also be provided for the annular grooves and opening angles for the bearing shells.
