Abstract

Toothed rack brush for cleaning a toothed rack of a toothed rack gear, with a toothed rack, a brush head with a plurality of bristles, which is rotationally arranged about a rotational axis, aligned in parallel to the toothed rack in order to carry out a rotational movement and is arranged in a linearly moveable manner to carry out a relative longitudinal movement relative to the toothed rack, a synchronization device for synchronizing the rotational movement with the longitudinal movement.

First claim

The invention claimed is:

1. A toothed rack brush for cleaning a toothed rack of a toothed rack gear comprising:
a toothed rack;
a brush head with a plurality of bristles, wherein the brush head is rotationally arranged about a rotational axis, aligned in parallel to the toothed rack in order to carry out a rotational movement,
wherein the brush head is further arranged in a linearly moveable manner relative to the toothed rack in a longitudinal direction of the toothed rack to carry out a relative longitudinal movement relative to the toothed rack; and
a synchronisation device for synchronising the rotational movement with the longitudinal movement, said synchronisation device comprising a toothed element which is coupled to the brush head and is in effective connection with an actuator of the toothed rack gear.

2. The toothed rack brush according to claim 1 , wherein the bristles are arranged along a helix.

3. The toothed rack brush according to claim 2 , wherein the toothed rack has helical teeth with a helix angle.

4. The toothed rack brush according to claim 3 . wherein the lead angle of the helix at least essentially corresponds to the helix angle of the toothed rack.

5. The toothed rack brush according to claim 1 , wherein the toothed element engages with the teeth of the toothed rack in order to rotationally drive the brush head in a longitudinal direction of the brush head relative to the toothed rack.

6. The toothed rack brush according to claim 1 wherein the toothed element engages with a take-off of an actuator of the toothed rack gear in order to drive the brush head.

7. The toothed rack brush according to claim 1 , wherein the toothed element is coupled to the brush head via a bevel gear.

8. toothed rack brush for cleaning a toothed rack of a toothed rack gear comprising:
a toothed rack;
a brush head with a plurality of bristles, wherein the brush head is rotationally arranged about a rotational axis, aligned in parallel to the toothed rack in order to carry out a rotational movement,
wherein the brush head is further arranged in a linearly moveable manner relative to the toothed rack in a longitudinal direction of the toothed rack to carry out a relative longitudinal movement relative to the toothed rack; and
a synchronisation device for synchronising the rotational movement with the longitudinal movement, wherein the synchronisation device comprises a brush head actuator connected to a control device of an actuator of the toothed rack gear.

9. The toothed rack brush according to claim 8 , wherein the bristles are arranged along a helix.

10. The toothed rack brush according to claim 9 , wherein the toothed rack has helical teeth with a helix angle.

11. The toothed rack brush according to claim 10 , wherein the lead angle of the helix at least essentially corresponds to the helix angle of the toothed rack.
