Abstract

Eine Rotordrehvorrichtung für eine Dampfturbine, deren Rotor ein Antriebsritzel (3) aufweist, an dem der Rotor (1) mit der Rotordrehvorrichtung (5) antreibbar ist, weist einen hydraulisch antreibbaren Außenzahnradmotor (6), der wenigstens zwei im Außeneingriff miteinander kämmende Zahnräder (7,8) und ein die Zahnräder (7,8) einhausendes Gehäuse (9) aufweist, und eine Kupplungseinrichtung (15 bis 22) auf, mit der die Rotordrehvorrichtung (5), wenn sie an der Dampfturbine montiert ist, mit dem Antriebsritzel (3) kuppelbar ist, wobei das Gehäuse (9) eine Aussparung (13) aufweist, mit der eines der Zahnräder (7) derart freigelegt ist, dass das freigelegte Zahnrad (7) bei der mit dem Antriebsritzel (3) gekuppelten Rotordrehvorrichtung (5) mit diesem in Eingriff steht, wodurch das Antriebsritzel (3) von dem freigelegten Zahnrad antreibar ist.

Figure imgaf001
A rotor rotating device for a steam turbine, whose rotor has a drive pinion (3) on which the rotor (1) with the rotor turning device (5) can be driven, has a hydraulically drivable external gear motor (6), the at least two meshing with each other in external engagement gears (7 , 8) and a housing (9) housing the gears (7, 8), and a coupling device (15 to 22) with which the rotor turning device (5), when mounted on the steam turbine, is connected to the drive pinion (3 ), wherein the housing (9) has a recess (13) with which one of the gear wheels (7) is exposed such that the exposed gear (7) coupled to the drive pinion (3) rotor rotating device (5) this is engaged, whereby the drive pinion (3) is driven by the exposed gear.
