Definitions

the invention relates to a Leitschaufelverstellvortechnische for a turbomachine and a turbomachine with a Leitschaufelverstellvortechnische.
Turbomachines known from practice have a rotor and a stator.
the rotor of a turbomachine comprises a shaft and a plurality of rotating together with the rotor blades, wherein the blades form at least one blade ring.
the stator of a turbomachine comprises a housing and a plurality of stationary vanes, wherein the vanes form at least one vane ring.
the known from practice vanes are made in one piece. From practice, it is already known to adjust the one-piece vanes of a shovel ring of a turbomachine via a Leitschaufelverstellvorraumraum such that the vanes are rotatable about an extending in the radial direction of the rotor vane rotary axis.
Leitschaufelverstellvorierien known from practice in this case have a drive shaft to which a drive motor can be coupled and which is drivable via the drive motor.
the rotation of the drive shaft via the drive motor with the aid of a control ring on all vanes of a vane ring is transferred, so therefore all vanes of a vane ring indirectly adjusted or rotated starting with the interposition of the control ring from the drive shaft.
a Leitschaufelverstellvortechnisch with a control ring is from the document GB 2398607 A known. In order to reduce flow pressure losses on a vane ring and to increase the efficiency, it is desirable to use multi-part vanes on vane rings.
each vane has in each case a front vane part and a rear vane part, which are each rotatable relative to one another about a common axis of rotation, namely the respective vane rotational axis.
the drive shaft is directly coupled to one of the vanes of the vane ring such that the vane parts of this vane ring vane are directly rotatable from the drive shaft without interposition of the control ring.
the drive shaft is indirectly coupled to the other vanes of the vane ring, such that the vane parts of the other vanes of the vane ring are indirectly rotatable from the drive shaft with the interposition of the control ring.
a drive lever engages in each case on a bearing journal of the front blade part and a bearing journal of the rear blade part of each guide blade, the drive levers of the blade parts of the guide blades being coupled to each other via a coupling device such that the blade parts of the guide blades can be rotated synchronously.
the vane adjusting device allows the rotation of multi-part vanes around radially extending guide vane rotation axes, namely, such that a front vane part and a rear vane part of each vane are respectively rotatable synchronously about a common axis of rotation.
the synchronous rotation of the blade parts of each vane to each other can be proportional or non-proportional. Blade parts of a vane are directly rotatable without the interposition of the control ring from the drive shaft, whereas the blade parts of the other vanes are rotatable indirectly with the interposition of the control ring of the drive shaft.
the control ring is preferably displaceable in the circumferential direction and in the axial direction and fixed exclusively in the radial direction. Blade parts of multi-part vanes of a vane ring can be rotated synchronously with the guide vane adjusting device according to the invention with the occurrence of low friction and torsional loading.
the respective coupling device in the region of each vane, is coupled to one of the drive levers about an axis parallel to the respective vane rotation axis, whereas the respective coupling device is coupled to the other drive lever via a pin in a guide groove of the respective other drive lever and is guided in a guide groove of a housing structure of the vane ring.
a single of the drive lever, which engage the bearing journal of the blade parts of the respective vane, is coupled to the control ring in the region of each vane. This allows a particularly advantageous displacement of the rotation initiated by the drive shaft rotation of the blade parts of the vanes on all vanes of the vane ring.
control ring is displaceable in the circumferential direction and in the axial direction, so that forces at coupling points between the control ring and the drive levers pivotally coupled to the control ring are perpendicular to the drive levers. Forces at the coupling points between the control ring and the drive levers coupled to the control ring are always perpendicular to the drive levers. In this way it can be ensured that bearings of the guide vanes or stator blade parts are not loaded by parasitic force components. Ultimately, this reduces the load on the vane parts and bearings, whereby the vane adjusting is exposed to lower loads and therefore can be dimensioned with less space requirement.
the turbomachine is defined in claim 11.
the present invention relates to a Leitschaufelverstellvortechnische for a turbomachine and a turbomachine with at least one such Leitschaufelverstellvortechnisch.
a turbomachine comprises a rotor with rotor-side rotor blades and a stator with stator-side stator blades.

the pin 32 engages with an opposite end in a guide groove 34 of the housing structure 26 of the vane ring.
the guide groove 33 of the respective drive lever 29 for the pin 32 is designed as a rectilinear slot and the guide groove 34 of the housing structure 26 designed as an arcuate slot.
the shape of the guide groove 34 in the housing structure 26 determines the ratio of the angles of rotation between the respective front blade portion 22 and the respective rear blade portion 23, thus determining, inter alia, whether the blade portions 22, 23 of each blade are rotated proportionally or non-proportionally to each other.
the drive lever 29 for the respective rear vane part 23 of the respective vane 21, which acts on the bearing journal 25 of this vane part 23, is coupled to the control ring 27.
