A reversing gear assembly (13) for a marine angle drive comprises a horizontal input shaft (15), to be connected to a horizontally mounted engine (11) and an inclined output shaft (16) to be connected to the propeller shaft (12). Gear casing (14) includes an intermediate shaft (17) which extends parallel with the output shaft (16). The input shaft (16) fixedly mounts a cylindrical gear (22) which meshes with a forward drive conical gear (23) on the output shaft (16) and with a reverse drive cylindrical gear (25) on the intermediate shaft (17). Center of engagement between the cylindrical gears (22, 25) is located on the sole common perpendicular line of the input and intermediate shafts (15, 17). Reverse drive gear train further includes two meshing cylindrical gears (26, 24) on the intermediate and output shafts (17, 16). The gears (23, 24) on the output shaft (16) are selectively coupled to this shaft by clutch means (32). The parallel arrangement of the output and intermediate shafts (16, 17) and the use of a single conical gear (23) contributes to reducing the manufacturing cost while permitting drive of propeller shaft in either direction with equal power. |
