Description

Bei Konstruktionsteilen aus 'keramischen Stoffen macht es Schwierigkeiten, bestimmte Maßtoleranzen einzuhalten, da beim Brennprozeß solche keramischen Teile ungleichmäßig schwinden. Auf der anderen Seite wird aber das Einhalten bestimmter Maße, besonders das Einhalten von Maßen der Achsabstände, gefordert, um ein ordnungsmäßiges Arbeiten .des Gerätes sicherzustellen.In the case of structural parts made of ceramic materials, it is difficult to to adhere to certain dimensional tolerances, since such ceramic parts during the firing process shrink unevenly. On the other hand, however, compliance becomes more specific Dimensions, especially compliance with the dimensions of the center distances, are required to ensure that the To ensure that the device works.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die für die Aufnahme einer Achse oder Welle vorgesehene Bohrung nicht kreisförmig, sondern vieleckig, beispielsweise sechseckig, vorgesehen wird, und daß in diese Bohrung ein entsprechender prismatischer Körper mit einer exzentrischen Bohrung eingesetzt wird. Beim Einsetzen des prismatischen Körpers lassen sich dannLängenunterschiede des keramischen Körpers dadurch ausgleichen, daß je nach der Plus- oder Minustoleranz der Mittelpunkt des exzentrischen Loches unter oder über die Mittellinie der prismatischen Bohrung des keramischen Körpers gelegt wird.According to the invention this object is achieved in that the for The hole intended to accommodate an axis or shaft is not circular, but polygonal, hexagonal, for example, is provided, and that a corresponding one in this hole prismatic body with an eccentric hole is used. When inserting differences in length of the ceramic body compensate by the fact that, depending on the plus or minus tolerance, the center of the eccentric hole below or above the center line of the prismatic hole of the ceramic body is placed.

Werden solche keramischen Teile mit harten mechanischen Stößen beansprucht, so ist es weiter vorteilhaft, diese harten Stöße von einem elastischen Zwischenglied auffangen zu lassen. Es ist deshalb vorteilhaft, den prismatischen Körper mit dem exzentrischen Loch aus leicht verformbarer Masse, z. B. Gummi, herzustellen, so daß harte Schläge über dieses Gummipolster auf den keramischen Körper übertragen werden.If such ceramic parts are subjected to hard mechanical impacts, so it is further advantageous to have these hard impacts from an elastic intermediate member to be caught. It is therefore advantageous to combine the prismatic body with the eccentric hole made of easily deformable mass, e.g. B. rubber to produce so that hard blows are transmitted to the ceramic body via this rubber pad will.

In der Abbildung ist ein Ausführungsbeispiel dargestellt. i ist ein derartiger keramischer Körper mit etwa kreuzförmigem Querschnitt. 2 sind die an beiden Enden angebrachten prismatischen Körper mit der exzentrischen Bohrung für die Aufnahme eines Bolzens. In der Abbildung ist der Fall dargestellt, daß der keramische Körper Minustoleranzen hat, da die Mittellinien der kreisrunden Bohrungen in dem prismatischen Körper außerhalb der Mittellinien der prismatischen Bohrungen liegen. Hätte der keramische Körper beispielsweise Plustoleranzen, so würde man die relative Lage der prismatischen Körper entsprechend ändern.An exemplary embodiment is shown in the figure. i is a such a ceramic body with an approximately cruciform cross-section. 2 are on both ends attached prismatic body with the eccentric hole for the inclusion of a bolt. The figure shows the case that the ceramic Body has minus tolerances, because the center lines of the circular holes in the prismatic body lie outside the center lines of the prismatic holes. If the ceramic body had plus tolerances, for example, one would use the relative Change the position of the prismatic bodies accordingly.
