| 摘要 |
A drive transmission which is particularly suitable for ship propulsion, comprises nested, contra rotating propeller shafts (32,34) which in one example are driven by a single input shaft (4) and which transmits contra rotating drives to the shafts (32,34) via respective planet carriers (24,22). particular advantages are the equal division of torque between the shafts (32,34) and the enabling of location of thrust bearings (122,124) and (126,128) in positions which are easy of access.
