Problems solved by technology

If rudder stocks with large lengths are to be forged, only a small number of forgings with comparable capacity are available, and most orders for rudder stocks, especially rudder stocks with a length greater than 10m, are close to the capacity of the forging, creating difficulties in these areas
Furthermore, such a long and often large-diameter rudder stock has a high weight, which usually exceeds the 100 ton limit

Embodiment Construction

[0015] exist figure 1 and 2 In the illustrated embodiment, reference numeral 10 designates the hull, 20 designates the rudder bearing in the rudder barrel with its ends 20a, 20b, 30 designates the rudder blade and 40 designates the rudder stock.

[0016] The inner rudder bearing 20 of the rudder tube, designed as a cantilever beam, is fixedly connected via its upper end 20 a to the hull 20 and has an inner bore 25 which accommodates a rudder stock 40 . The inner rudder bearing 20 of the rudder barrel penetrates into the rudder blade 30, and its rudder blade 30 is fixedly connected with the free lower end portion 20b of the rudder stock 40 passing through the inner hole 25 of the inner rudder bearing 20 of the rudder barrel. A preferably cylindrical lead-in portion 35 formed in the rudder blade 30 is defined by lateral outer plates 36, 37 for accommodating the free end 20b ( figure 2 ).

[0017] In order to support the rudder stock 40, the rudder bearing 20 in the rudder ba...

Abstract

The stock has end sections (41, 42) made of a wrought iron, and a middle stock section (45) connected with the end sections. The middle stock section is made of a carbon fibrous composite or graphite fibers, which form the section (45) in the form of windings. The windings extend into the opposite ends of the end section of the stock and are firmly connected with the end section. -

Description

technical field [0001] The invention relates to a rudder stock for a marine rudder. Background technique [0002] The rudder stock of the ship's rudder is mainly made of wrought iron. If rudder stocks with large lengths are to be forged, only a small number of forgings with comparable capacity are available, and most orders for rudder stocks, especially rudder stocks with a length greater than 10m, are close to the capacity of forging, which creates difficulties in these aspects . Furthermore, such long and often large-diameter rudder stocks have a high weight, which usually exceeds the 100-ton limit. This requires a special structure to support and hang the rudder blade on the rudder stock. Contents of the invention [0003] It is therefore the object of the present invention to provide a rudder stock which, in the case of a large length, has a low weight and is partly made of metallic material, in particular wrought iron, which nonetheless retains a high bending and t...
