"Device particularly for monitoring wear and breakage of components"

"Device particularly for monitoring wear and breakage of components"

The invention relates to a device for storing material and operating data of components as well as for monitoring wear and breakage, wherein the component is equipped with a microchip and an antenna coil for external reading of the data.

From older, unpublished applications of the applicant, electronic components encapsulated in plastic with transmission coils are known, whereby the data can be read out via these antennas.

In addition to the applicant's designs, a number of other solutions are known which deal in particular with the recording of data on rotating parts, for example in DE-199 25 460-Al, DE-199 37 203-Al, DE-694 12 390-T2, DE-198 10 674-Al, EP-0 509 745-Al, EP-0 685 297-Al, whereby in these literature references or in the following ones, wear data in particular is also to be recorded. For the sake of completeness, reference is also made here to DE-198 13 033, DE-35 24 101-Al, DE-298 13 731-Ul or DE-93 15 427-Ul.

Do the known solutions already have significant advantages over other wear monitoring devices?

However, they cannot be used in every case, as the geometry of the components often makes such monitoring impossible.

This is where the invention comes in, the task of which is to develop a system that enables the most precise monitoring possible, regardless of the geometry of the components, while at the same time not impairing the functionality of the antenna coils.

With a device of the type described at the outset, this object is achieved according to the invention in that a winding of the coil in the respective component is guided along a line adapted to the component geometry, such that in the event of component damage and breakage of the coil winding wire, the error that has occurred can be recognized immediately.

The invention ensures that monitoring, particularly against breakage, can be carried out regardless of the type of geometry of the component to be monitored. One coil winding can, for example, be distributed in a meandering manner over the component, it can be provided in the area of the outer contours, and so on.

In an embodiment, the invention provides that a coil winding is star-shaped, meander-shaped, zigzag-shaped or.

etc. is guided over the component surface.

It can be advantageous if the coil winding covering the component is cast and/or embedded in the component during its manufacture, as can be seen from the previously published
State of the art is already known.

The invention also provides, in particular in devices with at least two components that move relative to one another and are to be monitored, wherein one component is provided with a microchip and an antenna coil and the other component is also provided with a coupling or antenna coil, that each of the coil windings in the respective component
is guided along a line adapted to the component geometry. This allows, for example, pump wheels, fan wheels or similar to be recorded and the respective data
transmitted.

Further features, details and advantages of the invention
are based on the following description and the drawing. This shows in

Fig. 1 shows a symbolic representation of a component with a
Coil winding guided over the component surface,

Fig. 2 a tear-out from the front side of a component and in

Fig. 3 two counter-rotating, symbolically represented, wheel-shaped elements with the device according to the invention.

A microchip 2 for storing and recording the corresponding component data is cast into a component generally designated 1 in Fig. 1, which is provided with an antenna coil 3, via which the data can be transmitted to a reading head generally designated 4. One of the coil windings is clearly distributed in a meandering pattern over the component, this one coil winding is designated 5. If, for example, this component breaks in the area of the coil winding 5, this immediately interrupts the data transmission, so that a corresponding error can be detected immediately.

Fig. 2 shows the possibility of milling a circumferential groove 7 into the front side of a component, e.g. into a corresponding pump wear element, generally designated 6 in Fig. 2, with a receiving blind hole 8 for receiving the antenna coil 3a with electronics 2a. A corresponding antenna wire can then be inserted into the groove 7, with two variants shown in Fig. 2.

are to insert the antenna wire 5a as a simple uncorrugated wire or, if necessary, in a meandering or similar form, as shown on the right, this wire is designated 5b in Fig. 2. This device can then be inserted and, if necessary, cast in plastic or fixed there in another way.

Finally, Fig. 3 shows two disks rotating relative to one another. Here too, an antenna coil 3b is cast into one of the disks or fixed there in some other way in order to be able to transmit data to the reading head 4a. The component to be monitored in this way is designated 9 in Fig. 3, and this component is opposite the component 10 shown below, which carries a microchip 2a. Here, the design is such that a central coil, designated 11, transmits the data originating from the microchip 2a to the central coil 12 in the component 9 as a so-called coupling coil, so that this data can be passed on to the antenna coil 3b, which can then be read out by the reading head 4a.

It can be seen that in both components one of the coil windings, designated 5c or 5d, is guided over the surface of the component, so that in the event of a breakage the fault can be directly identified.

Of course, the described embodiments of the invention can be modified in many ways without deviating from the basic idea. As already mentioned above, any other configuration of the coil wire guide is possible, and the type of fixing of the antenna coils with the associated monitoring windings can also be carried out in different ways.
