Abstract

982,292. Turbine stop gear. FAIRFIELD SHIPBUILDING & ENGINEERING CO. Ltd. June 29, 1961 [June 30, 1960], No. 22866/60. Headings F1K. and F1T. A turbine trip gear includes a feeler 15 arranged to be displaced following excessive axial displacement of the turbine shaft 10 resulting from wear of the turbine thrust bearing, motion multiplying means associated with the feeler and a loaded valve 18 adapted to be held in a normal setting by a trip element 21 movable with the motion multiplying means, the construction being such that displacement of the feeler is accompanied by movement and ultimate withdrawal of the trip element and by displacement of the valve to bring about stoppage of the turbine. The trip gear may be carried by a cover 12 associated with the thrust bearing of the turbine being secured to the turbine casing, the bearing including a thrust collar 13 on the turbine shaft which collar is engaged by circumferentially spaced thrust bearing pads 14 and is engageable with the feeler. The gear may be arranged to operate in association with a turbine overspeed or other governor normally of centrifugal type incorporated in a pressure oil system from which release of pressure brings about closure of a stop valve of the turbine. Thus the valve 18 of the gear is interposed in the pressure oil system and so devised that when the gear is tripped the oil is by-passed from the system and drained into a sump within the turbine casing.
