    • An aircraft (10) having turboprop propulsion has a plurality of gas turbine engines (11), each with a two stage reduction gearbox (30, 41) with the engine output shaft (17, 17A) inline with the propeller drive output shaft (19, 51) to drive a propeller (12) in front of the engine in a tractor mode of propulsion. The input gear reduction stage (20) and output gear reduction stage (21) share a plurality of layshafts (22, 38) mounted in fixed circularly-spaced relation to each other about the axis of the ouptut shafts in the mechanical housing in the aircraft. Each layshaft of said plurality of layshafts has a layshaft first end toward the rear, input end of the gearbox, and a layshaft second end toward the output, front end of the gearbox. The layshaft gears are arranged to avoid any net thrust loading of the layshafts. Spur (26) and double helical (27) are used in FIG. 4, while spur gears (37 and 48) are used in FIG. 6 with suitable helix settings to neutralize end thrust on layshaft (38). Cantilever layshaft input gear (37) mounting in rear bearings (39) enables it to share some layshaft output gear (48) load sharing with the front bearing (40). A torquemeter (61) is conveniently situated at the gearbox input end. The engine output gear (25, 36) and gearbox output gear (28, 49), and propeller (12) all have colinear rotational axes.

    • PROBLEM TO BE SOLVED: To realize a simply constructed highly efficient transmission for an industrial vehicle. SOLUTION: The transmission has an input shaft 2, a first transmission mechanism 3, a second transmission mechanism 4, a clutch mechanism 5, a rotational direction changing gear row 6, a shifting gear row 7, and an output shaft 10. Both the transmission mechanisms 3, 4 are mechanisms for changing the speed of rotation inputted from the input shaft 2 between a plurality of stages. The clutch mechanism 5 is placed on the input side of both the transmission mechanisms 3, 4, and includes forward/reverse changing clutch mechanisms F, R for changing between forward and reverse movement, and also includes shift clutch mechanisms SC1, SC2 for selecting to which one of the first and the second transmission mechanisms 3, 4 rotation from the engine side is to be inputted. The rotational direction changing gear row 6 inputs rotation for forward movement and reverse movement into the forward/reverse changing clutch mechanisms F, R. The shifting gear row 7 inputs an output from the forward/reverse changing clutch mechanisms F, R into the shift clutch mechanisms SC1, SC2. COPYRIGHT: (C)2009,JPO&INPIT
