Abstract

Eine Exzenterteller-Schleifmaschine weist eine Schleiftellereinheit (8) auf, die drehbar an einem exzentrisch an einer Antriebswelle (5) angeordneten Exzenterzapfen (6) gelagert ist, so dass die Schleiftellereinheit (8) beim Betrieb eine planetarisch um die Achslinie (23) der Antriebswelle (5) kreisende Bewegung ausführt. Dieser kreisenden Bewegung kann zum Erreichen eines erhöhten Materialabriebs am Werkstück eine Rotationsbewegung um die Achslinie (24) des Exzenterzapfens (6) überlagert werden. Hierzu trägt die Schleiftellereinheit einen Zahnkranz (12), dem ein zur Antriebswelle (5) koaxialer, von der Schleiftellereinheit gesonderter Zahnkranz (19) an einem Ringkörper (20) zugeordnet ist. Der Ringkörper (20) ist drehbar gelagert und in axialer Richtung feststehend angeordnet. Die beiden Zahnkränze (12, 19) stehen dauernd in eingriff miteinander. Mittels einer Feststelleinrichtung (22) kann der ansonsten frei drehbare Ringkörper (20) arretiert werden.

Figure 00000001
An eccentric disc grinding machine has a grinding disc unit (8) which is rotatably mounted on an eccentric pin (6) arranged eccentrically on a drive shaft (5), so that during operation the grinding disc unit (8) is planetary around the axis line (23) of the drive shaft (5) circular motion. In order to achieve increased material abrasion on the workpiece, a rotating movement about the axis line (24) of the eccentric pin (6) can be superimposed on this circular movement. For this purpose, the grinding plate unit has a ring gear (12) to which a ring gear (19) coaxial with the drive shaft (5) and separate from the grinding plate unit is assigned on an annular body (20). The ring body (20) is rotatably mounted and arranged in a fixed manner in the axial direction. The two ring gears (12, 19) are in constant engagement with each other. The otherwise freely rotatable ring body (20) can be locked by means of a locking device (22).
