Abstract: There is provided a turbine including a hub body including a shaft for transmitting the torque generated by the turbine to a driven machine, a plurality of turbine blades carried by the hub body and rotatable about their longitudinal axes, an adjusting body in an interior of the hub body, arranged as a spherical link chain extending coaxially to the shaft and rotatable about a shaft axis of the shaft, and a guide rod chain for each of the plurality of turbine blades, including a smooth spherical shell having a uniform surface and two guide rods, including a first guide rod having a first end linked to the adjusting body via a swivel joint and a second guide rod having a first end linked to a second end of the first guide rod via the swivel joint.

Abstract: The invention relates to a turbine, especially for a flow power plant, comprising the following features: a hub body which comprises a shaft for transmitting the torque generated by the turbine to a driven machine; a plurality of turbine blades which are carried by the hub body and are twistable about their longitudinal axes; an adjusting body is provided in the interior of the hub body, arranged in the manner of a spherical link chain which extends coaxially to the shaft and is twistable about the shaft axis; a guide rod chain for each blade, comprising two guide rods, namely a first guide rod whose first end is linked to the adjusting body via a swivel joint, and a second guide rod whose first end is linked to the second end of the first guide rod via a swivel joint, and whose second end is twistably mounted on the hub body about the longitudinal axis of the respective blade; wherein the adjusting body comprises a drive pin and a spherical shell, and at least the first guide rod is spherically arranged a

Abstract: A rotor assembly includes a drive shaft; a rotor having rotor blades, which each comprise a profiled rotor blade section and a blade fastening section; wherein each blade fastening section comprises a first contact region and a second contact region, the first contact region being at least indirectly supported on the blade fastening section of a first adjacent rotor blade, the second contact region being at least indirectly supported on the blade fastening section of a second adjacent rotor blade; the blade fastening sections are fastened in a formfitting manner and/or by a screw connection on the drive shaft, so that there is a connection between rotor blade and drive shaft on an axial end face of the blade fastening section. Intermediate elements having an elastic intermediate layer are between the blade fastening sections of adjacent rotor blades.

Abstract: This invention relates to a method for web tear monitoring on a machine used for the production and/or treatment of a fiber material web, in particular a paper web or paperboard web, said machine being in particular a paper machine or coating machine on which the fiber material web is conveyed at a defined speed in its longitudinal direction along a defined path, wherein a web tear is detected by way of a light-emitting component and a light-receiving sensor in that light is emitted from the light-emitting component in the direction of the fiber material web to a defined target point and, given the presence of the fiber material web, is reflected and/or let through and/or directed in the target point to the light-receiving sensor.
