- Connection can be avoided, for example, a release of the handle from the machine housing and always ensure control of the power tool on the handle. Furthermore, a particularly simple and cost-effective production can be achieved with a cohesive connection, without the use of additional fastening means.
- the damping device is connected in an integral manner to the first housing part and to the second housing part by an injection molding process. This makes it easy on and inexpensively manufacture a power tool housing unit preferably of several materials. The attachment of the housing parts can be done without additional fasteners, since the housing parts are already firmly and durable connected by the injection molding alone.
- the hand-held power tool housing unit has a rotary joint via which the first housing part is connected to the second housing part.
- This hinge allows a rotational movement between the first housing part and the second housing part and thus also serves for the movement compensation between the first and second housing part.
- the damping device has a bellows-like construction.
- bellows in this case an elastic, “accordion-like” collapsing hose to be understood, which is mounted for damping reasons between the first housing part and the second housing part. Due to the movable due to the bellows embodiment of the damping device, the vibration transmission from the first housing part to the second housing part can be reduced or damped in a proper operation of the power tool.
- undesired tensile stresses and an associated vibration transmission in the damping device are avoided in the event of a tilting movement between the first and second housing parts.
- An overstretching of the damping device is due to the bellows-type construction avoided, whereby an extension of the life of the power tool is achieved.
- first housing part and / or the second housing part each have at least two shells,
- the shells can be filled after their preparation with components and connected to each other after filling become.
- a further advantageous reduction of the installation effort can be achieved by the damping device is at least formed in two parts.
- Damping has elastically deformable bending beam.
- the energy to be damped is then consumed in the bending work of the bending beam.
- the damping device is thereby elastically received within the housing unit. Vibration, vibrations and / or shocks are thus only attenuated or reduced transferred from the machine housing to the handle.
- the first housing is designed as a machine housing and the second housing as a handle.
- structurally simple and cost-effective transmission of vibrations, vibrations and / or impacts from the machine housing to the handle can be reduced or damped.
- this is in addition to the damping and thus a pleasant guidance of the power tool and a noise reduction during operation of the craft machine accessible.
- the hand tool is pleasant to run and quiet.
- the figure shows a simplified representation of a hand tool according to the invention with a Salesforcemaschinema- machine housing unit.
- the housing unit may encompass one or more components of the power tool.
- the component may be, for example, the machine part of the power tool with, in particular, an electric motor, a ventilation device, a gear unit, etc., a battery pack of the power tool, a charger for the battery pack of the power tool, etc.
- the housing unit all components the hand tool, apart from necessary openings and passages completely encloses.
