Claim 0:
1. A linear drive (1), comprising:
a drive shaft (10) arranged along a longitudinal axis (X);
at least two propelling teeth (20); and
at least one gear rack (30) having a plurality of teeth (31),
wherein the at least two propelling teeth (20) are reciprocatingly movable perpendicularly to the longitudinal axis (X) and are drivingly connected to the drive shaft (10) in such a way that the at least two propelling teeth (20) carry out at least one cyclical reciprocating movement (21) during the course of one rotation (φ) of the drive shaft (10) and dip into and out of the at least one gear rack (30) for generating a propelling motion in the longitudinal axis (X),
wherein a respective one of the propelling teeth (20) has a greater, equal or smaller tooth length (L1) and/or a greater tooth height (H1) than a corresponding one of the teeth (31) of the gear rack (30), and
wherein the cyclical reciprocating movement (21) of the at least two propelling teeth (20) is carried out with a phase shift (Δφ).
