Bearing assembly for a drive shaft guided in a protective tube

A bearing assembly for a drive shaft guided in a protective tube is provided with bearing tube segments arranged in the protective tube one after another in a longitudinal direction of the protective tube, wherein the drive shaft connects a tool and a driver. The bearing tube segments are penetrated by the drive shaft. The bearing tube segments include bearing sections. The bearing sections are provided with a central bearing sleeve and support elements projecting away from an outer circumference of the bearing sleeve. The bearing sleeve is radially supported by the support elements on an inner circumference of the protective tube. The bearing section with its bearing sleeve and support elements is formed as one piece. The bearing tube segments have a length measured in a longitudinal direction of the protective tube and the sum of the lengths of the bearing tube segments is greater than 60% of a length of the protective tube. 本发明涉及种用于在保护管中引导的驱动轴的支承组件，该驱动轴将工具与驱动器连接。支承组件具有多个布置在保护管中的支承管部段，其在保护管的纵向方向上处于个接个并且由驱动轴
