A linear movement device has a housing and a carriage which can move in a longitudinal direction with respect to the housing, wherein the housing extends with an essentially constant U-shaped cross-sectional shape in the longitudinal direction, with the result that the housing bounds a guide cavity, wherein the guide cavity is covered with a toothed belt which extends in the longitudinal direction, wherein the toothed belt is attached at both ends to the housing with the result that said toothed belt defines a toothed belt plane, wherein at least one separate guide rail which extends in the longitudinal direction is arranged within the guide cavity, on which guide rail at least one separate guiding carriage is mounted in a longitudinally movable fashion, which guiding carriage is permanently connected to the carriage, wherein a first and a second deflection wheel, which deflect the toothed belt out of the toothed belt plane, are rotatably attached to the carriage, wherein a rotatable drive wheel, which is in drive-transmitting engagement with the toothed belt, is arranged between the first and the second deflection wheels. The carriage has a single-piece carriage base body which extends in the longitudinal direction, wherein said carriage base body is embodied as a closed tube essentially over its entire length, with the result that it bounds a carriage cavity, wherein the guiding carriage is attached to the outside of the carriage base body, preferably directly to the outside of the carriage base body, wherein the toothed belt is guided through the carriage cavity, and wherein the first and second deflection wheels and the drive wheel are arranged within the carriage cavity.

Linear movement device with omega drive

A linear unit having a main module unit and a drive unit in which the main module unit has a housing with a table part that a drive belt is able to move in the longitudinal direction; the drive belt is wound around a drive roller, which is connected to a drive unit, and around a freewheeling roller; and the drive belt is connected to the table part and is divided into an upper span and a lower span, and a guide element is situated on the base leg of the housing and is able to separate the upper span from the lower span.
