Beschreibung
Zusammenfassung:	The present invention relates to a linear drive (1) having at least one toothed rack (20) oriented along a longitudinal axis (L) and at least two slides (30) which are movable transversely to the longitudinal axis (L), and a drive shaft (60), wherein the at least two slides (30) are coupled to the drive shaft (60) in such a way that the at least two slides (30) each carry out at least one cyclic and out-of-phase movement in the course of one revolution of the drive shaft (60) and thereby push off by an operative contact at the at least one toothed rack (20) to generate propulsion in a direction of the longitudinal axis (L), wherein the linear drive (1) has at least one compensation means (15), by means of which the operative contact between at least one of the at least two slides (30) and the at least one toothed rack (20) is preloaded
