ABSTRACT:
A marine reversing gearing having a drive shaft, a forward clutch, a forward pinion coaxially arranged with respect to the drive shaft and capable of being coupled therewith by means of the forward clutch for forward travel. Two intermediate gears continuously mesh with the forward pinion, there also being provided two intermediate pinions which are rigidly connected with a respective one of the intermediate gears. A large gear continuously meshes with both intermediate pinions. There are also provided a reverse clutch and a rearward pinion which is coaxially arranged with respect to the drive shaft and can be coupled therewith by the reverse clutch for rearward travel, and two reversing pinions are driven by the rearward pinion. The intermediate gears meshing with the forward pinion exclusively transmit power as forward gears during the forward travel. Both of the reversing pinions mesh with the rearward pinion and with a respective rearward gear, and each of both intermediate pinions also are fixedly connected with one of the rearward gears.
