Description

(1) The invention is explained in closer detail by reference to the drawings in 3D, wherein:

(2) FIG. 1 shows the rotating apparatus with three link chains.

(3) FIG. 2 shows the subject matter of FIG. 1 in a second view.

(4) FIG. 3 shows the subject matter of FIG. 1 in a third view.

(5) FIG. 4 shows the subject matter of FIG. 1 in a top view in the direction towards the rotating axis of the rotating apparatus.

(6) FIG. 5 shows the individual components of a turbine blade bearing.

(7) FIG. 6 shows a rotating apparatus, installed in a hub body, in a first view.

(8) FIG. 7 shows the subject matter of FIG. 6 on an enlarged scale in a second view.

(9) FIG. 8 shows the subject matter of FIG. 6 on an enlarged scale again and in a third view.

(10) FIG. 1 shows the most important parts for adjusting the blades of a turbine (not shown). The central component is an adjusting body 10. The adjusting body 10 substantially has the shape of a cup. It comprises a drive pin 10.1 and a spherical shell 10.2.

(11) Three guide rod chains are connected to the spherical shell 10.2. They are completely identical in the present case. Deviations from this are also possible however. Each guide rod chain comprises two guide rods. The configuration of the three guide rod chains will be explained by reference to one of these guide rod chains with guide rods 1 and 2. FIG. 2 shows that the guide rod 1 comprises two swivel joints, namely a first swivel joint A and a second swivel joint B. Swivel joint A produces an articulated connection between the adjusting body 10 and the first end of the first guide rod 1. The first guide rod 1 could also be referred to as “articulated lever”.

(12) Swivel joint B is situated at the second end of the articulated lever 1 and represents an articulated connection to the second guide rod. Said second guide rod 2 could also be referred to as blade connection guide rod.

(13) The second end of the blade connection guide rod 2 has the shape of a circular ring. The circular ring comprises boreholes 3 for guiding screws through said boreholes, by means of which the blade (not shown) is fixed to the blade connection guide rod 2. The second end of the blade connection guide rod 2, which is shaped as a circular ring, is embedded in a hub body 11, which will be described below in closer detail.

(14) FIG. 4 shows a view of the adjusting body 10 in the direction of its rotating axis.

(15) FIGS. 5 to 8 also show a hub body 11 in addition to the adjusting body, the three guide rod chains, and the blade connections 4.

(16) FIGS. 6, 7 and 8 show clearly how the adjusting body 10 and the three guide rod chains are installed in the hub body 11. The respective second end of the second end, i.e. the so-called blade connection guide rod, is shown in particular (see the circular ring shape with the boreholes for the fastening screws for fastening the three blades).

(17) FIG. 2 shows in particular that the guide rod 1 with the swivel joints A and B is curved in the side view. It has the same radius of curvature as the spherical shell 10.2 of the adjusting body 10. This obviously applies to all three guide rod chains. The first guide rod 1 or articulated lever is curved in a spherical manner.

(18) The hub body 11 is driven during operation of the turbine. The torque generated by the turbine is transmitted via a shaft (not shown) to a power engine, e.g. a generator. The adjusting body 10 can be rotated about the rotating axis of the drive pin 10.1, even during operation. The rotating also simultaneously rotates all blades by the guide rod chains, e.g. by 180° or more.
