ABSTRACT:
A reversing gear assembly (13) for use in yachts having an angle drive system 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 forward direction drive path includes meshing cylindrical gear (18) and conical gear (20) on the input and output shafts (15, 16). The reverse direction drive path has on the input and output shafts (15, 16) two cylindrical gears (19, 21) with which a skew cylindrical gear (22) on the intermediate shaft (17) meshes at respective axial halves of the skew gear. The center of engagement between the meshing gears (19, 22) on the input and intermediate shafts (15, 17) is located on the sole, common perpendicular line of these shafts. A reversing clutch (23) is disposed on the output shaft (16).
The minimum number of shafts and gears for attaining the forward and reverse direction drives and a speed reduction in a reversing gear assembly is three shafts and five gears. Using only one conical gear in such an assembly reduces the troublesome backlash-adjusting work associated with conical gears.
