Drive shaft 120 by bearing arrangement with can around rotation axis x rotation by the way of be bearing in housing
In 105 and be provided with cutter acceptance division 140, this cutter acceptance division is arranged in transmission case in the axial direction
In the front area 171 of body 110 and exemplarily there is drill chuck.Cutter acceptance division 140 is used for
Receive cutter and can be formed in drive shaft 120 or accessories type be connected with drive shaft.Drive
Axle 120 and case of transmission 110 in the front area 171 of case of transmission 110 from housing 105
Stretch out.It is internal that the Background Region 173 of case of transmission 110 is positioned at housing 105.
In hand held power machine 100 runs, variator 170 is rotated driving by driving motor 180.
At this point it can be pointed out that the structure of variator 170, especially planetary transmission and operation principle and with
Shown, to be used for adjusting the clutch of torque common effect is commonly known, therefore in this explanation
In the scope of book, this is not described in detail.In this utility model, case of transmission 110 is by extremely
A few positive and threadless attachment means are maintained at the housing 105 of hand held power machine 100
In.Here, attachment means includes the first connection geometry, it is at the rear portion of case of transmission 110
In region 173 periphery along case of transmission 110 constitute and with the shaped in housing 105
Two connect geometry correspondence.
Correspondingly, the first connection geometry both can make to act on the axial direction of rotation axis x
Axial force on case of transmission 110, can also make to act on the torque on case of transmission 110
Geometry transfer is connected to housing 105 by second.
Being illustrated in detail in figs 2 and 3, first connects geometry has at least two in the circumferential
Spaced, be perpendicular to the outward extending holding element of rotation axis x 172,174.Correspondingly,
In the housing 105 of hand held power machine 100 it can be seen that correspondence, be perpendicular to rotation axis x to
The notch 112,114 of interior sensing, wherein, holding element 172,174 positive ground are embedded into notch
In 112,114.Holding element 172 in the illustrated embodiment, 174 and corresponding notch 112,114
T shape, l shape and constitute circularly, wherein, however, it would be possible to imagination is possible not only to transmission and acts on speed change
Axial force on device housing 110 and the institute of the torque acted on case of transmission 110 can be transmitted
There is embodiment.
Axial force load between housing 105 and case of transmission 110 spreads out of in shown holding element
Mainly carried out by the week upwardly extending surface portion at case of transmission 110 in 172, and housing
Torque between 105 and case of transmission 110 mainly by holding element 172,174 in rotary shaft
The upwardly extending surface portion in line x side spreads out of.
Correspondingly holding element 172,174 and corresponding notch 112,114 such as H-shaped or star
The structure of shape is also feasible.In addition it can be seen in figs. 2 and 3 that some holding elements 172,174
Rotation axis x direction is positioned on identical height.It turned out for case of transmission 110 and shell
Particularly advantageously, holding element 172,174 along case of transmission in transmission torque between body 105
110 are positioned apart from along the biggest periphery, in order to have as far as possible about for rotation axis x
Big lever arm.
Two circular holding elements 174 are arranged, the most not only in transmission case with staggering in the axial direction
The biggest transmission along rotation axis x on body 110 and can be equipped with on housing 105 bear
The surface of lotus.
Being illustrated in detail in figures 4 and 5, case of transmission 110 has the back of the body in Background Region 173
Face 175, it is basically perpendicular to rotation axis x and blocks case of transmission 100 backward.This can be seen that,
3rd connects geometry is formed on the back side 175 of case of transmission 110, and the 3rd connects geometry
Shape is corresponding with the 4th connection geometry being formed in housing 105.Correspondingly, the 3rd connection is several
What shape connects geometry by the 4th and is possible not only to act on direction in rotation axis x-axis
Axial force on case of transmission 110 and the torque on case of transmission 110 can be will act on
It is delivered on housing 105.3rd connects geometry has on the direction of rotation axis x to evagination
Retainer member 176 for case of transmission 110.Correspondingly, the housing of hand held power machine 100
105 acceptance divisions 116 with correspondence so that be embedded into acceptance division 116 retainer member 176 positive
In.
Retainer member 176 and its corresponding acceptance division 116 cross as shown in the figure and about two mutually
Vertical mirror image axis y, z-axis is constituted symmetrically, and wherein, specular axis y, z are perpendicular to rotate
Axis x.At this, retainer member 176 exists the most crisscross from rotation axis x as shown in the figure
Extend radially outwardly in circumference.But also as in holding element 172,174 and the notch 112 of its correspondence,
In 114 like that, it is also contemplated that arrange multiple retainer member being distributed the most on the back side
176, they are received by the corresponding acceptance division 116 in housing 105.Therefore retainer member 176 is right with it
The acceptance division 116 answered may be constructed various imaginabale shape in principle, and it is suitable for, and is possible not only to
Transmission acts on the axial force on case of transmission 110, and can transmit and act on case of transmission
Torque on 110.
In the illustrated embodiment, spreading out of of axial force is perpendicular to rotary shaft by retainer member 176
Line x extend surface portion and carried out by the surface portion opposed with it on housing 105.And
Torque between case of transmission 105 and housing 110 is parallel to rotary shaft by retainer member 176
Line x extends or has at least one surface portion being parallel to the component that rotation axis x extends and spreads out of.
Correspondingly, the acceptance division 116 of retainer member 176 and its correspondence can also t shape, H-shaped, l shape
And/or constitute crisscross.Meaningfully, retainer member 176 is about at least one mirror image axis y
Axial symmetry, the most as shown in the figure about two orthogonal mirror image axis y, z-axis is constituted symmetrically.
As at Fig. 2 to 5 in be clearly shown that as, at the Background Region of case of transmission 110
Retainer member 176 positive ground outstanding on 173 is embedded into the housing at hand held power machine 100
In the acceptance division 116 constituted in 105.Then, the housing 105 of hand held power machine 100 is the most fixing
On the case of transmission 110 of variator 170 so that be arranged in case of transmission 110 front area
It is right that holding element 172,174 in 171 is disposed in the housing 105 of hand held power machine 100
Notch 12,114 positive ground is answered to receive.It is possible not only in this way be delivered in rotation axis x
Axial direction on act on the axial force on case of transmission 110, and can transmit and act on change
Torque on speed device housing 110.Thus obtain case of transmission 110 at hand held power machine 100
On housing 105 simple, easily perform, stable and fix reliably.
It is contemplated that other embodiment except illustrated in addition to embodiment illustrated, they are permissible
Other change and combination including feature.
