Abstract

A power tool, in particular a router, includes a motor shaft, at least one output shaft defining an output axis that is coaxial with the output shaft, and at least one electromotive drive acting on the motor shaft. The motor shaft defines a motor axis with the electromotive drive which is coaxial with the motor shaft. The motor axis and the output axis are arranged substantially parallel to and at a distance from one another.

Claims (46)

1. A power tool, comprising:

a motor shaft;

at least one output shaft defining an output axis that is coaxial with the at least one output shaft;

at least one electromotive drive that acts upon the motor shaft, the motor shaft, with the one electromotive drive, defines a motor axis that is coaxial with the motor shaft; and

a housing including at least one hand-rest surface intersected by the output axis of the at least one output shaft; and

a spindle driven by the at least one output shaft and extending downwardly out of the housing, the spindle having a tool receiver configured to receive a routing tool,

an operating element configured to activate the at least one electromotive drive, the operating element being arranged between the motor axis and the output axis,

wherein the motor axis and the output axis are arranged substantially parallel to each other and at a distance from each other,

wherein a transmission of torque from the at least one electromotive drive to the at least one output shaft is effected via a belt drive, and

wherein the power tool is a router.

2. The power tool as claimed in claim 1 , wherein the distance between the motor axis and the output axis is between 50 mm and 80 mm.

3. The power tool as claimed in claim 1 , wherein the distance between the motor axis and the output axis is between 15 mm and 60 mm.

4. The power tool as claimed in claim 1 , wherein the operating element is arranged on and/or in a region adjacent to the at least one hand-rest-surface.

5. The power tool as claimed in claim 1 , further comprising:

a first wall which is substantially parallel to an insertion direction of a rechargeable battery; and

a second wall which forms the at least one hand-rest surface.

6. The power tool as claimed in claim 5 , wherein an angle between the first wall and the second wall is between 70° and 75°.

7. The power tool as claimed in claim 1 , wherein the belt drive is arranged along the motor axis at a first upper free end of the motor shaft and at a second upper free end of the at least one output shaft.

8. The power tool as claimed in claim 2 , wherein the distance between the motor axis and the output axis is 65 mm.

9. The power tool as claimed in claim 3 , wherein the distance between the motor axis and the output axis is between 40 mm and 20 mm.

10. The power tool as claimed in claim 3 , wherein the distance between the motor axis and the output axis is 24 mm.

11. The power tool as claimed in claim 1 , wherein the belt drive is connected to an end of the output shaft that is opposite the spindle.

12. A power tool, comprising:

a motor shaft;

at least one output shaft defining an output axis that is coaxial with the at least one output shaft;

at least one electromotive drive that acts upon the motor shaft, the motor shaft, with the one electromotive drive, defines a motor axis that is coaxial with the motor shaft;

a housing including at least one hand-rest surface intersected by the output axis of the at least one output shaft; and

two adjusting elements arranged on the power tool in a space produced between a parallel arrangement of the motor shaft and the at least one output shaft,

wherein the motor axis and the output axis are arranged substantially parallel to each other and at a distance from each other,

wherein a transmission of torque from the at least one electromotive drive to the at least one output shaft is effected via a belt drive, and

wherein the power tool is a router.

13. The power tool as claimed in claim 12 , further comprising:

a base plate arranged on the two adjusting elements.

14. The power tool as claimed in claim 13 , wherein the base plate is arranged asymmetrically on the at least one output shaft.

15. A power tool comprising:

a motor shaft;

at least one output shaft defining an output axis that is coaxial with the at least one output shaft;

at least one electromotive drive that acts upon the motor shaft, the motor shaft, with the one electromotive drive, defines a motor axis that is coaxial with the motor shaft;

a housing including at least one hand-rest surface intersected by the output axis of the at least one output shaft;

a spindle driven by the at least one output shaft and extending downwardly out of the housing, the spindle having a tool receiver configured to receive a routing tool; and

a rechargeable battery arranged above the spindle,

wherein the motor axis and the output axis are arranged substantially parallel to each other and at a distance from each other,

wherein a transmission of torque from the at least one electromotive drive to the at least one output shaft is effected via a belt drive, and

wherein the power tool is a router.

16. The power tool as claimed in claim 15 , further comprising an operating element configured to activate the at least one electromotive drive, the operating element being arranged between the motor axis and the output axis.

17. The power tool as claimed in claim 15 , wherein the rechargeable battery is arranged parallel to the motor axis and to the output axis.
