Abstract

646,632. Variable speed gearing. LOCKHEED AIRCRAFT CORPORATION. April 27, 1945, No. 10728. Convention date, March 6, 1942. [Class 80(ii)], [Also in Groups XI, XII, XIII, XXVI, XXVIII and XXXIII] A gas turbine jet propulsion engine has the turbine coupled to the compressor or compressors through a differential gear transmission which allows the relative speeds of the turbine and compressor or compressors to be varied during operation. The gear shown, Fig. 11, is mounted between two compressors driven by a single turbine. The shaft 76 of one compressor is connected to a planetary drive spider 194 carrying six planetary pinions which mesh with a sun gear 201 keyed to the shaft 32 of the second compressor and a ring gear 203 mounted on the spider 194 by ball bearings 205 and 206. An extension 196 of the spider 194 is rotatable on the shaft 32 and has fixed on its end the fluid coupling impeller 199. The speed of one compressor relative to the other can be varied either by filling or emptying the hydraulic coupling or by increasing or decreasing the load on the auxiliary drive shafts 208, 388. The amount of oil in the hydraulic coupling is regulated by a needle valve 447, Fig. 19. controlled by bellows 439 which are responsive to the discharge pressure of one of the compressors. An arrangement in which the gearing is modified to make it suitable for driving a reciprocating compressor and its associated valve gear is also described.
