<p>The present invention relates to a shaft rotating device for turbomachines, having a hydromechanical overriding clutch. Radial pistons (19), operated by means of pressure pistons (16), produce the connection between an inner ring (20) and an outer ring (21), when they are subjected to compressed oil, as a result of which a hydraulic motor (1) and the machine shaft (22) of a turbomachine are coupled. The radial pistons (19) are moved against the force of plate springs (17), so that they are disengaged in their quiescent position and engage when compressed oil is supplied. The hydraulic motor and clutch are supplied from the same high-pressure oil system (30) with interposition of a common restrictor (31). By means of an additional adjusting restrictor (37) in the compressed oil outlet (36) of the hydraulic motor (1), the shaft rotating device can be set such that all the desired functions of the hydraulic motor and clutch are carried out simply by switching the compressed oil supply on and off. …<IMAGE>… </p> |
