Drive device for a rudder propeller

The innovation relates to a drive device for a rudder propeller of a watercraft ο »dgl · * at the the propeller is driven by a drive motor via a gearbox containing a shaft leading under the water surface ben is, the part of which is under the water has a reduction from the speeding into Laügössö «ad at the d @ r Propeller for the purpose of steering the vehicle around an approximately vertical axis pivotable 1st *

The gearbox between the drive motor and the propeller is Z-shaped in its basic structure / i.e. the motor initially has a Drive transmission device with essentially v / aagereeht horizontal main axis driven. This direction of force is with a bevel gear or the like. diverted into a wave leading under the waterline and from there the drive is again by means of a gearbox οβdgl, on the approximately horizontal Lying propeller shaft deflected The efficiency of the rudder propeller depends, among other things, on the ratio of the propeller diameter to the diameter of the one under the water <- ^ 3 gear housing containing angular gear. The size of the QfD the latter depends on the size of the gears of the transmission £ f £ and this again from the torque to be transmitted

The function of such a rudder propeller is known per se and does not need to be described as such, so that only the intended effect needs to be described 16, 17, 22, 23 are transferred to the lower part 52 of the overall transmission located in the pear. Since the pear, which contains the underwater part of the gear, is rotatably mounted in the shaft housing 19 with the underwater housing 2C and the control sleeve 39, the central cylinder not only exerts a rotary function on the propeller via the submerged gearbox, but also a reduction torque on the housing parts 25g 2O ₃ 39 »which strive * to rotate against the central shaft.

After the innovation, the overwater part 55 receives the overall gearbox, i.e. the part of the gearbox that is mounted in the structural parts that are fixed relative to the Viasser vehicle, no corrosion or even a translation, as shown in FIGS. 2 and 3 is drawn. This causes the central ball to rotate at a higher rate Speed »e.g. with the speed of the drive motor or even faster. This has the consequence that the torque at the Central v / el is correspondingly small and thus also the reaction moment. The main part of the reduction, preferably the entire reduction or even more than the reduction from the engine to the propeller is placed in the underwater part 52 of the transmission, so that this reduction can be housed in the "pear", the reduction is divided into several levels. i.e. so divided over several pairs of wheels. Eiri special "trick" the The innovation is to generate the reduction with a planetary gear, a spur planetary gear being particularly advantageous It's because spur gears are better sesrssitet wersgE kösnes and therefore run more smoothly and are relatively more durable than bevel gears.
