Definitions
- Hand tool in particular electrically operated hand tool
- the invention relates to a hand tool, in particular an electrically operated hand tool, according to the preamble of claim 1.
- Eccentric drives which actuates a rotatably connected to the drive shaft transmission lever to implement the rotational movement of the eccentric disc in the oscillating movement of the drive shaft.
- the oscillating drive produces vibrations which contribute to the development of noise and, in particular, represent a mechanical load on the components of the power tool. It is therefore desirable to take appropriate measures such as the use of damping elements
- the invention has for its object to effectively reduce vibrations in a hand tool over a long period of operation with simple measures.
- the hand tool according to the invention which is in particular an electrically operated hand tool, for example an angle grinder, has in a housing a drive unit which drives a tool via a drive connection.
- the housing of the power tool is constructed in two parts and comprises two separate housing parts, between which a primary damping element is arranged, which contributes to an effective vibration damping or reduction between the housing parts and thus in the entire hand tool.
- the drive unit and the drive shaft with the tool accommodated thereon are arranged in the front housing part, whereas the rear housing part is designed as a grip, in which the electronics is accommodated and actuation switches are arranged.
- the primary damping element both the vibrations are damped, which emanate from the drive unit, as well
- Vibrations caused by the operation of the tool In particular vibrations generated by eccentric drive such as unbalance vibrations are reduced via the primary damping element, but also vibrations in the machine tool.
- the vibration load acting on a handle in the rear housing part is considerably reduced.
- the primary damping element also has a force-transmitting function and holds the two housing parts together.
- a secondary damping element is arranged between the two housing parts of the power tool in parallel to the primary damping element.
- This secondary damping element is at least approximately free of forces at regular function of the primary damping element and only comes into operation when the primary damping element is deformed beyond a defined level. In such a deformation also changes according to the relative position between the two housing parts, whereupon the secondary damping element comes into operation and can develop its damping effect.
- a graded, hierarchical operation is achieved: With intact primary damping element or loads on the hand tool below a threshold, the damping takes place exclusively or at least almost exclusively on the primary damping element.
- the function of the primary damping element for example, by material aging, or the function of the damping element is ineffective or extraordinary high forces occur, for example by impacts from the outside, so that the
- the secondary damping element cooperates with a securing element which bridges the two housing parts.
- the securing element can be designed in particular in the way - A -
- Secondary damping element on the securing part in the event of an overrun or a reduction in the function of the primary damping element effective vibration reduction.
- Securing part and secondary damping element can be optimized with respect to their different tasks.
- soft materials that do not serve for power transmission, but only for vibration damping, whereas the securing member does not damp vibrations, but serves for power transmission.
- the securing element is firmly connected to a housing part and loosely connected to the other housing part, in particular via the secondary damping element.
- a bolt-receiving connection device is provided in the area of the loose connection, in which a bolt, for example on the housing part, in a receptacle on
- Securing member engages, wherein the secondary damping element at least partially surrounds the bolt, for example, in an embodiment as a damping ring which is held either in the receptacle or on the bolt.
- the bolt projects loosely into the receptacle and is only via the secondary damping element with the
- Secondary damping element formed as an independent component, which is arranged or held on the securing element - possibly also on one of the housing parts. According to an alternative advantageous embodiment, however, it is provided that the secondary damping element is integrated into the securing element, in which case both an insertion of the executed as an independent component secondary damping element in the security part is possible as well as a one-piece or one-piece design of
- securing parts in particular in the form of a special structural design of the security part.
- securing parts have a portion with a wave or bellows shape; this section forms the secondary damping element, which can undergo a longitudinal expansion or compression at a corresponding application of force, wherein the damping takes place via the internal damping of the material of the securing part.
- the secondary damping element can either consist of known damping materials such as elastomers, thermoplastics, thermosets, TPE or other plastics. But it is also possible a design as a knit, which for example made of metal, plastic or other
- liquid or semi-liquid or viscous media are also suitable, for example silicone, gel, grease or oil.
- Gaseous media for the secondary damping element are also possible.
- the liquid or gaseous media have the advantage that the damping properties can be easily influenced or adjusted on the one hand by the pressure of the fluid and on the other hand by the choice of the viscosity of the fluid.
- secondary damping element in the material of the Securing part for example, executions as wire rope, carbon fiber, coil spring or the like into consideration.
- the integration in the securing part is carried out either by subsequent attachment of the secondary damping element to the securing part, for example by clamping in recesses or approaches of the security part or fastening using conventional fastening techniques, or even during the production of the security part, for example by encapsulation with the material of the security part or a other material.
- the secondary damping element is embedded for this purpose, for example, as an insert in the mold of the security part.
- an encapsulation after completion of the security part, wherein via the injection process, a connection to the security part is achieved.
- a further expedient combination of securing part and secondary damping element provides that the securing part is designed as a wire rope and the secondary damping element as pulled over the wire rope hose.
- the hose has the desired damping properties, the wire rope, however, is suitable for power transmission.
- the combination of securing part and secondary damping element is formed deformable and can therefore be adapted to different geometries in the power tool.

In the front, the front housing part 3 facing region, the securing part 10 has a recess 12 into which a one-piece with the front housing part 3 formed bolt 13 protrudes. Between the inner surface of the recess 12 and the bolt 13, a secondary damping element 14 is arranged, for example, from a soft
- the secondary damping element 14 may be connected to the securing part 10 and / or to the bolt 13.
- the secondary damping element 14 is designed as a damping ring, which is arranged in the intermediate space between the outer jacket of the bolt 13 and the inner wall of the recess 12 in the securing part 10.

In this central recess of the bolt 13 projects, wherein the relative positioning between the bolt and the secondary damping element takes place either in such a way that the lateral surface of the bolt is in contact with the inwardly directed nubs or, according to another Execution, in such a way that between the knobs and the bolt is an air gap.
- FIG. 5 largely corresponds to that of FIG. 1, so that reference is made to the local description with respect to the matching structure.
