Embodiment Construction

[0033] exist figure 1 and 2 shows a power tool designed as an electric saber saw 1 (also referred to as a foxtail saw or “reciprocating saw”) in the form of a sawing machine or sawing device for a straight reciprocating saw blade. The saber saw 1 is designed as a hand-held power tool, which has an electric drive motor in a housing consisting of two housing shells 2 a , 2 b for driving a tool designed as a saw blade 3 . saw blade 3 as figure 2 It can be seen that an oscillating, rectilinear working movement is performed according to the double arrow 4 , in which the saw teeth 5 of the saw blade 3 on a saw tooth line 6 are moved forward and backward. The working movement 4 takes place along a zigzag line 6 . Instead of a linear reciprocating movement, the saw blade can also perform an orbital movement.

[0034] Such as figure 1 and 2 It can further be seen that the saber saw 1 is provided with a support device 7 comprising a support element 8 on the carrier part 9 and a f...

Abstract

The invention relates to a tool machine (1), in particular a reciprocating saw, comprising an output spindle (24) that moves back and forth and comprising a drive motor (28), said spindle and motor being coupled to each other via a transmission system (30). A longitudinal face (38) of the output spindle (24) and a longitudinal face (40) of the drive motor (28) run adjacent to each other such that the drive motor (28) lies next to the output spindle (24). A very compact design is thereby produced.

Description

technical field [0001] The invention relates to a power tool with a reciprocating output spindle according to the preamble of claim 1 . Background technique [0002] Motor-driven saber saws or hand-held saws are known, such as electrically driven foxtail saws, in which the saw blade performs a reciprocating, oscillating working movement. [0003] US 2009 / 022307 A1 and US 2010 / 0162579 A1 disclose machine tools with a reciprocating spindle and a drive motor, which are coupled to each other via a transmission. The longitudinal axes of the drive motor and the driven spindle form an obtuse angle here. The drive motor, driven spindle and handle are arranged in a star shape, so that the machine tool requires a relatively large amount of space. Accordingly, the upwardly standing drive motor may block the view of the cut product. [0004] US7818887 discloses a machine tool with a reciprocating driven spindle and a drive motor, which are coupled to each other via a transmission, wh...
