Definitions
- the invention relates to a system with a tool holder according to the preamble of claim 1.
- the grinding machine tool holder has a driver and a clamping nut.
- the driver is pushed onto a collar of the drive shaft with an assembly opening and clamped non-positively against a support surface of the drive shaft via the clamping nut.
- the driver has a collar which extends in the axial direction on the tool side and which is radially connected to two has opposite sides on its outer circumference recesses which extend in the axial direction to a bottom of the collar. Starting from the recesses, a groove extends in each case against the drive direction of the drive shaft on the outer circumference of the collar. The grooves are closed against the drive direction of the drive shaft and taper axially from the recesses against the drive direction of the drive shaft.
- the grinding wheel has a hub with a mounting opening in which two opposite, radially inward-pointing tongues are arranged.
- the tongues can be introduced into the recesses in the axial direction and then into the grooves in the circumferential direction, counter to the drive direction.
- the grinding wheel is positively locked in the axial direction via the tongues in the grooves and is non-positively fixed by the tapering contour of the grooves During operation, the frictional connection increases as a result of reaction forces acting on the grinding wheel, which act counter to the drive direction.
- a stopper arranged on the circumference of the collar which is movably mounted in an opening in the axial direction. In a working position with the grinding wheel facing downwards, the stopper is deflected axially by gravity in the direction of the grinding wheel, closes the groove in the direction of the recess and blocks a movement of the tongue located in the groove in the drive direction of the drive shaft.

- the driving device advantageously has at least one functional element which forms at least part of the means.
- Existing components can be used advantageously and additional components for realizing the agent can be avoided.
- the means can be designed in different ways, for example the means can be formed by a specially shaped tensioning hook which blocks a rotational movement required for complete assembly when the insert tool is reversed.
- At least one corresponding coding is particularly advantageous, which forms the means for avoiding reverse mounting of the insert tool.
- a reverse reversal of the insertion of the insert tool onto the tool holder can advantageously be avoided, and an inexpensive and simple protection against incorrect assembly can be achieved in which existing components can be used and additional components can be avoided.
- the coding can be formed by various components which appear sensible to a person skilled in the art. However, the coding is particularly advantageously formed at least in part by a functional element, such as, for example, a tensioning hook or a latching element, which secures the insert tool in the initial direction.

- a hub can be achieved which is inexpensive and easy to manufacture.
- the hub can be made from a special material, in particular from a sheet metal, so that a recess corresponding to the functional element can be made precisely and inexpensively, for example with a stamping process.
- the hub can also be formed from other materials which the person skilled in the art considers useful, such as, for example, from a plastic, a glass fiber, a composite, etc., and / or can also be integrally formed on the insert tool.
- the insert tool particularly advantageously has a hub with a shape pointing in the axial direction. Protection of the functional elements can be achieved simply and inexpensively and, in addition, the shape advantageously prevents the insert tool from being reversed. If the hub is formed from a sheet metal part, the formation can be formed inexpensively in a deep-drawing process.
- the shape can have various shapes which appear useful to the person skilled in the art. If the hub is cup-shaped or if the shape extends in the central area of the hub over a larger area, the shape can be molded on with a simple tool and, in addition, a high stability of the hub can be achieved. Furthermore, in particular in hand-held power tools that have a protective hood, the functional element can be positively locked with a Recess of the hub of the insert tool can be prevented in the case of an inverted assembly, namely by the insert tool resting on the protective hood as a result of the shaping in an inverted assembly before the functional element comes into engagement in the recess.
- the solution according to the invention can be used in various hand-held power tools which appear to be suitable for this purpose, in particular in angle grinders.
