    • A linear module having a housing with a holder being secured against rotation and having an element for axial adjustment relative to the housing. The holder is surrounded by a sleeve proximate the housing, with the sleeve being provided with an external thread and an internal thread with the same direction of rotation, but with a differing lead. A guiding tube, being a first tube, is shaped as a rectangular tube and is located within the housing. A second tube is located within the guiding tube and is also constructed as a rectangular tube, which is capable of coaxial movement within the guiding tube. A linear motor connected to the second tube with the linear motor exerting a force on the second tube which is coaxial to a common axis of the guiding tube and the second tube. The linear motor is rigidly connected at one end to the holder. Guiding rail include a bearing for guiding coaxial movement of the second tube within the first tube with the guiding rails allowing for adjusting the bearing spatially. A position measuring device is located in at least one of the guiding tube or the second tube for determining a relative coaxial position of the guiding tube as compared with the second tube and a control unit in communication with the position measuring device for indicating the relative coaxial position of the guiding tube relative the second tube.
    • 具有壳体的线性模块具有保持器抵抗旋转而被固定,并且具有用于相对于壳体进行轴向调节的元件。 保持器被靠近壳体的套筒包围,套筒设有外螺纹和具有相同旋转方向但具有不同引线的内螺纹。 作为第一管的引导管被成形为矩形管并位于壳体内。 第二管位于引导管内,并且也被构造成矩形管,其能够在引导管内同轴运动。 连接到第二管的线性马达与线性马达在第二管上施加力,其与引导管和第二管的公共轴线同轴。 线性电机的一端与支架刚性连接。 引导轨包括用于在第一管内引导第二管的同轴运动的轴承,导轨允许空间调节轴承。 位置测量装置位于至少一个引导管或第二管中,用于确定与第二管相比导引管的相对同轴位置;以及控制单元,与位置测量装置连通,用于指示相对同轴 引导管相对于第二管的位置。
