has been named as the inventor.

Atlas-Werke Aktiengesellschaft in Bremen Steering system for ships

Addition to patent 649 Patented in the German Empire on November 3, 1936

The invention relates to the further development of that described in the 649,973 patent Steering system for ships with a rudder quadrant fixed on the rudder shaft and a resilient member between the pinion engaging in the rudder quadrant and the rowing machine driving this pinion. According to the main patent, the resilient member is on the head of the hollow pinion shaft arranged.

A particularly useful and useful for the connection with the auxiliary rudder device simple design can be achieved in that the spring housing accommodating the spring members with the worm or gear of the auxiliary rudder device firmly connected and for receiving the spring members in a vertical position Arrangement is formed. The known shutdown of the worm gear shaft is advantageously carried out by a detachable spline connection between spring housing and worm gear shaft.

To connect the vertical spring links to the pinion shaft, both directions of rotation rotatably mounted angle levers are provided, which control the torques of the rudder drive transmitted to the pinion shaft and the shocks coming from the rudder by transmission catch on the spring links.

By arranging the spring members vertically, this is not the case when they are arranged horizontally provided according to the main patent annular, the spring housing enclosing intermediate member continued, so that the spring housing The outside is free to attach the worm gear or gear wheel of the auxiliary rudder device. This enables the spring housing to be connected in a particularly simple manner

Claims (3)

allows the gear of the auxiliary rudder device, which the spring members not only at Using the rowing machine, but also when using the auxiliary rowing device Effect can come, so that the shocks coming from the rudder are also on the handwheel do not make the auxiliary rudder device uncomfortable. Furthermore, the perpendicular Arranging springs has the advantage that the springs are easily accessible and adjustable can be by placing actuators in the spring housing with externally accessible Heads are provided around the spring members, which are expediently designed as disc springs to bias or change it. / The invention is illustrated by way of example in the accompanying drawings, and it shows: Fig. Ι a side view of the steering gear, FIG. 2 shows a plan view of this, FIG. 3 shows a longitudinal section through the head the pinion shaft on a larger scale, Fig. 4 is a view of this head on a scale of Fig. 3, Fig. 5 is a section along the line V-V of Fig. 3. In the drawings, as in the Arrangement according to the main patent 2 a rudder stock, 4 one by wedge S with it connected rudder quadrant, 6 one in the Rudder quadrant engaging pinion, 7 a hollow pinion shaft, 8 part of the rowing machine, namely a worm gear shaft, 25 its worm gear, which is driven by a worm 24 on a shaft 23 of an electric motor 26 is driven. 3 is a housing for worm and worm wheel. According to the invention, the spring members in the illustrated embodiment are from each have a set of disc springs 30, arranged inside a body 31, the the connection with an auxiliary rudder, e.g. B. Manufactures hand rudder power transmission line. At 32 the handwheels of this line are shown, at 33 the power transmission line is shown. To connect to the power transmission line, a worm gear is provided on the body 31 or gear, in the illustrated embodiment a worm wheel 34 is provided. It forms part of the body 31. The worm wheel meshes with a worm 35 which is driven by the power transmission line 33 from. The body 31 is free rotatable on a shaft of the rowing machine, in the illustrated embodiment the pinion shaft 8 is arranged. A detachable intermediate piece is required to connect the two shafts, e.g. Keil36. It is advantageously secured by a screw bolt 37 held in place. The spring members 30 are expediently arranged vertically in the body 31 and act on pressure members 38. Actuators 39 are provided, by means of which the springs are provided with a forward movement . voltage can be given. For this purpose, heads 40 are provided on the actuators, which are freely accessible from the outside. A type of angle lever 41 is rotatably mounted on the body 31, which is expedient act in a double arrangement with the help of pressure surfaces 42 on the pressure members 38, when its other pressure surfaces 43 are acted on from the pinion shaft 7, e.g. by radial surfaces 44 of a flange 45 of the pinion shaft. The system works as follows: In ordinary operation, the hand rudder power transmission line is disconnected from worm wheel 34 in any way. The pinion 6 is from the rowing machine on parts 23, 24, 25, 8, 36, 31, 45 and 7 driven. As soon as impacts on the rudder and thus on the rudder quadrant 4 come, the pinion shaft 7 is slightly rotated with the flange 45, and the bumps are gently braked in the spring members 30 and finally in the worm drive 24, 25 intercepted so that they do not come on the drive motor 26 and its parts can. If, on the other hand, the hand rowing device is to be switched on, then the wedge 36 taken out, whereby the steering machine is switched off from the rudder quadrant. If now shocks come to the pinion 6, they are again by the spring members braked and finally intercepted in the worm gear 34, 3.5, so that they are not can affect the handwheels 32 of the hand rowing device. Pa τ entans v κ ü c η ε: ι. Steering system for ships according to patent 649 973 with a worm gear shaft that can be switched off, characterized in that the Spring housing (31) to accommodate the spring links. (30) in a vertical arrangement formed, with the worm or gear wheel (34) of the auxiliary rudder device firmly connected and for the purpose of switching off the worm gear shaft (8) with a detachable wedge intermediate piece (36) is provided. 2. rudder system for ships according to claim i, characterized in that for both directions of rotation of the pinion shaft between the vertical spring members (30) and the pinion shaft (7) rotatably mounted Angle levers (41) are switched on, the the torques of the rudder drive it transmitted to the pinion shaft and that of the The rudder absorbs incoming shocks by transmitting them to the spring links. 3. Rudder system for ships according to claims 1 and 2, characterized in that that in the spring housing (31) actuators (39) with externally accessible Heads are provided to the spring members designed as disc springs (30) to bias or change it. 1 sheet of drawings
