Title (EN) TOP DRIVE AXIAL BEARING HAVING A DISTANCE SENSOR FOR DRILLING SYSTEMS
(FR) PALIER DE BUTÉE À TÊTE ROTATIVE D'ENTRAÎNEMENT COMPRENANT UN CAPTEUR DE DISTANCE POUR INSTALLATIONS DE FORAGE
(DE) KRAFTDREHKOPFAXIALLAGER MIT ABSTANDSSENSOR FÜR BOHRANLAGEN
Abstract:
(EN) The invention relates to a top drive axial bearing (600) for a drilling system, comprising a first bearing ring (632), in particular a shaft disk, a second bearing ring (634), in particular a housing disk, and a plurality of rolling elements (636), wherein the plurality of rolling elements (636) is arranged between the first bearing ring (632) and the second bearing ring (634). According to the invention, the top drive axial bearing (600) comprises at least one distance sensor (640) for sensing the distance between the first and second bearing ring, for determining measurement parameters of the drilling operation. The distance sensor (640) is preferably an inductive proximity sensor, in particular an eddy current sensor.
(FR) L'invention concerne un palier de butée (600) à tête rotative d'entraînement pour une installation de forage. Le palier comprend une première bague (632), en particulier un disque de butée, une deuxième bague (634), en particulier un disque de carter, et une pluralité de corps roulants (636), la pluralité des corps roulants (636) étant agencés entre la première bague (632) de palier et la deuxième bague (634) de palier. Selon l'invention, le palier de butée (600) à tête rotative d'entraînement comporte au moins un capteur de distance (640) destiné à détecter la distance entre la première et la deuxième bague de palier, pour établir les paramètres de mesure de la procédure de forage. Le capteur de distance (640) est de préférence un capteur de proximité inductif, en particulier un capteur à courants de Foucault.
(DE) Kraftdrehkopfaxiallager (600) für eine Bohranlage mit einem ersten Lagerring (632), insbesondere einer Wellenscheibe, einem zweiten Lagerring (634), insbesondere einer Gehäusescheibe, und einer Vielzahl von Wälzkörpern (636), wobei die Vielzahl der Wälzkörper (636) zwischen dem ersten Lagerring (632) und dem zweiten Lagerring (634) angeordnet ist. Erfindungsgemäß umfasst das Kraftdrehkopfaxiallager (600) mindestens einen Abstandssensor (640) zur Erfassung des Abstandes zwischen dem ersten und zweiten Lagerring, zum Ermitteln von Messparametern des Bohrvorgangs. Der Abstandssensor (640) ist vorzugsweise ein induktiver Näherungssensor, insbesondere ein Wirbelstromsensor.
