Abstract

1308977 Variable speed gears; fluid friction brakes GOODYEAR TIRE & RUBBER CO 30 June 1970 [14 Aug 1969] 31492/70 Headings F2D and F2E A planetary gear train (e.g. of three interconnected gear sets 18, 20, 22) has its reaction member adjustably braked to vary the transmission ratio by a brake comprising a liquid filled chamber 34, 36 in which a sun gear 48 driven by the reaction member of the gear train meshes with pinions 38 to form gear pumps, the volume of the chamber being reduceable (e.g. by an annular piston 54 under hydraulic pressure via 56, 58) to thereby restrict flow: of the liquid (e.g. round the side of the pinions 38) and brake the sun gear. The chamber may have small accumulators 68 to collect displaced fluid. The input of the gear train may have an aircraft wheel 12 splined to a common ring gear 84 for the trains 18, 20, 22 and the output drive an impeller 16 to brake the wheel.
