Abstract

A power tool system includes at least one power tool separation device and at least one portable power tool. The power tool separation device includes at least one cutting unit and at least one guide unit which forms a closed system at least together with the cutting unit. The portable power tool includes a motor unit configured to be coupled to the cutting unit of the power tool separation device. At least in the mounted state, a longitudinal axis of the motor unit extends at least essentially perpendicular to the longitudinal axis of the guide unit.

First claim

The invention claimed is:

1. A machine-tool system, comprising:
a portable machine tool having a motor unit; and
at least one machine-tool parting device including at least one cutting strand and at least one guide unit which forms a self-contained system at least together with the at least one cutting strand, the at least one machine-tool parting device configured to be mounted to and supported by the portable machine tool, wherein,
when the at least one machine-tool parting device is mounted to and supported by the portable machine tool, a motor unit longitudinal axis of the motor unit runs at least substantially perpendicular to a longitudinal axis of the guide unit,
the at least one guide unit is generally planar in a first plane,
the motor unit longitudinal axis and the longitudinal axis of the guide unit in a mounted state are arranged at least substantially in a second plane parallel to the first plane,
the portable machine tool includes a torque transfer shaft which defines a third longitudinal axis, the third longitudinal axis perpendicular to the first plane,
the at least one machine-tool parting device has a torque transmission element mounted at least partially in the guide unit, and
the torque transmission element, at least in an unmounted state, is arranged in the guide unit so as to be linearly movable with respect to the guide unit at least transversely with respect to a cutting direction of the cutting strand and/or along the cutting direction.

2. The machine-tool system as claimed in claim 1 , wherein the portable machine tool has at least one support unit configured for support on a workpiece, the longitudinal axis of the guide unit in a mounted state extending through said support unit at least substantially perpendicularly at least with respect to a support surface of the support unit.

3. The machine-tool system as claimed in claim 1 , wherein the portable machine tool has a gearing unit comprising a bevel gear.

4. The machine-tool system as claimed in claim 1 , wherein the cutting strand has at least one cutter carrier element which, on a side of the cutter carrier element facing toward the torque transmission element of the machine-tool parting device, has at least one recess into which, in at least one operating state, the torque transmission element engages so as to drive the cutting strand.

5. The machine-tool system as claimed in claim 4 , wherein the cutter carrier element is configured with at least a substantially circular-arc-shaped form at least on the side facing toward the torque transmission element.

6. The machine-tool system of claim 1 , wherein the at least one cutting strand is a continuous loop cutting strand.

7. A machine-tool system, comprising:
a portable machine tool having a motor unit with a first longitudinal axis; and
at least one machine-tool parting device configured as a self-contained system to be mounted to and supported by the portable machine tool, the at least one machine-tool parting device including a cutting strand guided by a guide unit having a second longitudinal axis, the guided cutting strand defining a cutting plane, wherein when the at least one machine-tool parting device is mounted to the portable machine tool (i) the first longitudinal axis is substantially perpendicular to the second longitudinal axis, (ii) the first longitudinal axis and the second longitudinal axis are substantially arranged in a second plane parallel to the cutting plane, and (iii) the portable machine tool includes a torque transfer shaft which defines a third longitudinal axis, the third longitudinal axis perpendicular to the cutting plane, wherein
the machine-tool parting device has a torque transmission element mounted at least partially in the guide unit, and
the torque transmission element, at least in an unmounted state, is arranged in the guide unit so as to be linearly movable with respect to the guide unit at least transversely with respect to a cutting direction of the cutting strand and/or along the cutting direction.

8. The machine-tool system as claimed in claim 7 , wherein the portable machine tool has at least one support unit configured for support on a workpiece, the second longitudinal axis in the mounted state extending through said support unit at least substantially perpendicularly with respect to a support surface of the support unit.

9. The machine-tool system as claimed in claim 7 , wherein the portable machine tool has a gearing unit comprising a bevel gear.

10. The machine-tool system as claimed in claim 7 , wherein the cutting strand has at least one cutter carrier element which, on a side of the cutter carrier element facing toward the torque transmission element of the machine-tool parting device, has at least one recess into which, in at least one operating state, the torque transmission element engages so as to drive the continuous loop cutting strand.

11. The machine-tool system as claimed in claim 10 , wherein the cutter carrier element is configured with at least a substantially circular-arc-shaped form at least on the side facing toward the torque transmission element.

12. The machine-tool system of claim 7 , wherein the cutting strand is a continuous loop cutting strand.
