Abstract

1,140,115. Toothed gearing. DAVID BROWN GEAR INDUSTRIES Ltd. 8 Aug., 1967 [12 Aug., 1966], No. 36165/66. Heading F2Q. An epicyclic gear train comprises an element supported by an hydraulic mechanism of variable torsional rigidity. As shown, an annulus 10 is supported circumferentially by three piston and cylinder assemblies 12, one end of each cylinder being connected hydraulically with a master cylinder 15, and the other end of each cylinder being connected hydraulically with a sump 19. The master cylinder 15, sump 19 and an accumulator 18 all communicate hydraulically with a bore 20 formed in a valve body 21 containing a spool 22 adapted, when moved from a neutral position, to cause the master cylinder to communicate hydraulically with either the accumulator 18 or the sump 19. The spool 22 is connected to annulus 10 by a rod 23. A pump 24, driven from a sun gear 8, is connected hydraulically to sump 19 and accumulator 18. The master cylinder 15 contains a piston 16 acted upon by a spring 17, so that effectively the annulus 10 is connected to its casing by the spring 17, and hence its torsional rigidity increases as its angular displacement increases.
