MARINE DRIVE POWER TRANSMISSION

摘要

A marine reversing gearing having a forward clutch which is coaxially arranged with respect to a drive shaft. A pinion of a first gearing stage or train can be coupled with the drive shaft by means of the forward clutch. Two mutually parallel gears of the first stage continuously mesh with the pinion of the first stage. A power take-off shaft can be driven by means of both gears of a second gearing stage or train. There is also provided a set of reversing gears composed of a number of reversing gears and at least one reverse clutch which is likewise coaxially arranged with regard to the drive shaft. The set of reversing gears can be coupled with the pinion of the first gearing stage by said at least one reverse clutch. For engaging and disengaging the forward and reverse clutches a slowly rotating auxiliary drive having reversible direction of rotation is connected by means of a reverse movement blocking device with the drive shaft.
