Description
Technical field
The present invention relates to a kind of hand held power machine as described in the preamble as claimed in claim 1.
Background technology
The known hand held power machine that is become by hammer drill and/or cutter hammer mechanism, it comprises that a motor unit and gear unit and one are by the auger spindle line and/or impact the processing axis that axis constitutes.At this, gear unit has some rotations, these rotations perpendicular to or to be parallel to described processing axis ground directed.
Summary of the invention
The present invention relates to a kind of hand held power machine, particularly hammer drill and/or cutter hammer machine, it comprises a motor unit and a gear unit and a processing axis.
The present invention proposes, and at least one transmission mechanism of gear unit has a rotation directed obliquely with respect to the processing axis.Here particularly be interpreted as a kind of unit that rotatablely moves that is used to transmit and/or change for " gear unit ".That particularly be interpreted as tool fitting for " processing axis " and/or rotation that can be positioned on the cutter in the tool fitting and/or impact axis can import to pulse on the described cutter that can be positioned in the tool fitting on the direction of this axis.In addition, particularly be interpreted as for " directed obliquely ": it is directed that rotation is neither parallel nor perpendicular to processing axis ground, and preferably pressing from both sides into one between 95 ° and 175 ° or the angle between 5 ° and 85 ° with processing axis, particularly preferably is between 100 ° and 150 ° or the angle between 10 ° and 60 °.Can realize very the compact structure mode and particularly can save structure length by corresponding configuration, exactly, particularly when the rotation of transmission mechanism has component at least one direction that extends in the processing axis, can realize above-mentioned situation.
At this, transmission mechanism can think that significant various mechanism constitutes by those skilled in the art, as by bearing shaft, belt pulley etc., but particularly advantageously constitute by a gear and/or by an axle at least in part, can realize compact structure mode and favourable power stream thus.If transmission mechanism constitutes (this motor drive shaft is considered as transmission mechanism equally clearly on meaning of the present invention) by a motor drive shaft, then particularly motor unit can be integrated in the machine hand tool housing with saving the position especially.In addition, the center of gravity of motor unit can be advantageously consistent with boundary condition on its position.Here particularly be interpreted as a kind of like this axle for " motor drive shaft ", this can drive by a turbine unit and/or by the electromagnetic unit of a motor unit.
In addition, when transmission mechanism is made of a speed change level, can save structure space.Here particularly be interpreted as a kind of like this unit for " speed change level ", this unit has different inputs and output radius, wherein a torque is continued to be delivered on the parts that are associated to torque of speed change level input and by the output radius by the input radius.
The solution of the present invention is suitable for all hand held power machines that those skilled in the art see fit in principle, but particularly advantageous is the hand held power machine that is suitable for having impact unit, although so that still can realize special compact structure mode for the required additional member of percussion unit.
At this, percussion unit can have the various driver elements that are used for converting to rotatablely moving ballistic motion, for example have an eccentric unit or advantageously have an oscillation bearing (Taumellager), this oscillation bearing can be integrated again with saving the position especially.Here particularly be interpreted as a kind of like this bearing for " oscillation bearing ", wherein owing to the swing mechanism that is bearing in obliquely on the supporting device, the oscillating motion that when this supporting device rotation, will produce swing mechanism.
In another configuration of the present invention, propose, hand held power machine has a motor drive shaft that is provided with driven region, this driven region is at least partially disposed on the side of the center of gravity that deviates from motor unit of processing axis, particularly can advantageously will is used for motor unit and motor drive shaft by the predetermined structure height of other construction unit and can realize little structure height generally thus.Same be suitable for be: hand held power machine has a motor drive shaft that is provided with driven region, and this driven region is at least partially disposed on the deviating from the side of processing axis of center of gravity of motor unit.
