Abstract

Eine Vorrichtung zur Feineinstellung des Abstandes zwischen zwei Elementen weist folgendes auf: ein Verbindungsglied (10), das das erste Element (2) und das zweite Element (3) miteinander verbindet; ein erstes Abstandseinstellglied (4) und ein zweites Abstandseinstellglied (5); wobei das erste Abstandseinstellglied (4) mit einem ersten Gewinde (25) versehen ist, das mit einem zugeordneten Gegengewinde (40) eines der Elemente (2; 3) zusammenwirkt; wobei das zweite Abstandseinstellglied (5) mit einem zweiten Gewinde (52) versehen ist, das mit einem zugeordneten Gegengewinde (46) des ersten Abstandseinstellglieds (4) oder des anderen der Elemente (3; 2) zusammenwirkt und wobei das erste Gewinde (25) und das zweite Gewinde (52) unterschiedliche Gewindesteigungen aufweisen.

Figure imgaf001
A device for finely adjusting the distance between two elements comprises: a link (10) interconnecting the first member (2) and the second member (3); a first distance adjusting member (4) and a second distance adjusting member (5); wherein the first Abstandseinstellglied (4) is provided with a first thread (25) which cooperates with an associated counter-thread (40) of one of the elements (2; 3); wherein the second distance adjusting member (5) is provided with a second thread (52) cooperating with an associated mating thread (46) of the first distance adjusting member (4) or the other of the members (3; 2), and wherein the first thread (25) and the second thread (52) have different thread pitches.
