Abstract:
1. A shaft coupling arrangement comprising: an input shaft operable to rotate about a first axis; an output shaft operable to rotate about a second axis; a gearing arrangement operable to engage said input and output shafts together for rotation in the same angular direction at different angular speeds, wherein said gearing arrangement includes a plurality of nested bevel gears; a first bevel gear engaged to said input shaft for rotation about said first axis; a second bevel gear engaged to said output shaft for rotation about said second axis; a layshaft operable to rotate about a third axis; and third and fourth bevel gears fixed to said layshaft and encircling said third axis, wherein said third bevel gear is meshed with said first bevel gear and said fourth bevel gear is meshed with said second bevel gear such that rotation of said input shaft in a first angular direction at a first angular velocity results in rotation of said output shaft in the first angular direction at a second angular velocity different from said first angular velocity.
