Some general aspects of the invention provide a foundation fixing unit (202, 204, 400) for fixing a tower (108) of a wind energy converter (100) onto a foundation (110). The unit comprises a fixation plate (202) fixable to the foundation (110), walls forming at least one tower fixation hole (300) in the intermediate plate (202) for passing a tower fixation bolt (220) through the fixation plate (202) in order to fix the tower (108) to the fixation plate (202), a tower fixation nut (400) arranged below the at least one tower fixation hole (300) for receiving a threaded portion of the tower fixation bolt (220) and a nut cage (204) holding the tower fixation nut (400), the nut cage (204) being attached to a bottom surface (222) of the fixation plate (202). Under further aspects, the invention provides a wind energy converter tower comprising the foundation fixing unit (202, 204, 400) and a method for fixing a wind energy converter tower onto a foundation.

A method for adjusting a pivotally mounted rotor blade of a wind energy converter includes controlling a first drive and a second drive to collectively turn the rotor blade into an operating position; detecting whether a failure of the first drive has occurred; activating, when the failure of the first drive has occurred, a first activatable lockout connected to the rotor blade, which prevents turning of the rotor blade into the operating position while allowing turning of the rotor blade into a feathered position; and controlling, when the failure of the first drive has occurred, the second drive to turn the rotor blade into the feathered position.

The invention relates to a silencer (1) for noise-laden gas pipes, especially for a suction pipe and/or an exhaust pipe of an internal combustion engine, comprising an outer pipe (2) with an inlet side (3) and an outlet side (4), a plurality of diaphragm rings (9, 9′, 9″, ′″, 9″″) each with an outer surface connected (5) to the inner surface of the outer pipe (2), at least one insert (6) with an outer surface connected (7) to the inner surface of the outer pipe (2) and/or the diaphragm rings (9, 9′, 9″, 9′″, 9″″) and with a plurality of openings (8) which are closed on one side. Said insert (6) forms sub-pipes for the gas flow in the silencer, and the openings (8), which are closed on one side, open into the sub-pipes, the depth thereof being /4 in relation to the wavelength of a frequency to be silenced. At least one perforated wall (10, 10′, 11, 11′), extends between at least two diaphragm rings (9, 9′, 9″, 9′″, 9″″) whereby an outer surface is connected (7) to at least one inner surface of the two diaphragm rings (9, 9′, 9′″, 9″″, wherein at least one resonance cell is fixed between the two diaphragm rings (9, 9′, 9″, 9′″, 9″″) of the perforated wall (10, 10′, 11, 11′) and the outer pipe (2).
摘要:
In the drive train of a combustion engine an auxiliary arrangement is arranged which is to be coupled with an axial flow machine including a stator and a rotor, in order to perform an actuating movement. The stator has a coil arrangement, and the rotor has an essentially cup-shaped support for permanent magnet elements. The coil arrangement of the stator has at least one cylindrical winding and is at least partially enclosed by two essentially pot-shaped magnetic flux yokes. Each of the pot-shaped magnetic flux yokes has side areas with magnetic flux poles whose outsides are oriented towards the permanent magnet elements of the rotor. The magnetic flux poles of the stator are arranged spaced apart from the permanent magnet elements of the rotor. The magnetic orientation of neighboring permanent magnet elements towards the air gap alternates.

This invention provides a nacelle of a wind energy converter and a corresponding mounting method of a nacelle of a wind energy converter and a generator for a wind energy converter. The nacelle includes a main frame; a generator including a stator and a rotor; a generator housing attached to the main frame and at least partially enclosing the stator and a rotor space; wherein the generator housing (20; 20′) has a first and second side face (S1, S2); wherein the first side face (S1) of the generator housing (20; 20′) exposes the rotor space (21); and a flange rotatably supported on the main frame and having a first end which is connected to the rotor; wherein the rotor extends into the rotor space (25) from the first side face (S1) without being supported in the generator housing.

A power unit bearing, in particular for motor vehicles, is characterized by mechanically integrally joining a conventional bearing, in particular a hydraulic bearing, to a connectable or disengageable hydraulic switching module for the purpose of matching the power unit characteristics to changing operational conditions of this power unit. The switching module is inserted between a chassis-side base plate of the conventional bearing body and a chassis-side adapter of the power unit bearing.
摘要:
An intake silencer is designed as a broadband silencer for noises causes by intake of combustion air into internal combustion engines. To achieve the broadband effect, an axial sequence of resonator chambers with different volumes is formed by partitions which extend transversely to the intake pipe in a resonator that surrounds the intake pipe Each resonator chamber communicates through openings in the wall of the intake pipe with the air sucked through the intake pipe. By matching the open surface area of the openings, the thickness of the wall of the intake pipe in the area of the openings and the volume of the resonator chambers, a continuous broadband silencing may be set even over a wide frequency range, the range of practical interest in the present application extending combustion from to 1 to 10 kHz. In motor vehicles with an internal combustion engine, a supercharger and an air charge cooler, the intake silencer is advantageously arranged in the pressure pipe joint of the supercharger, directly behind it or integrated therein, but in any case at a certain distance upstream of the air charge cooler.

A fluid guideline with at least two structural elements made of substantially soundproof material has at least one opening for sound damping. An impedance change (in particular in the form of an impedance discontinuity) of the flow resistance of the fluid flowing through the fluid guideline is present between two adjacent structural elements, and the at least one opening is arranged in the region of the impedance change between two adjacent structural elements.

The invention provides oil-in-water emulsions comprising recombinant collagen-like polymer in an amount sufficient to act as stabiliser of the emulsion. The polymer is especially a polypeptide which is free of helix structure, has an isoelectric point at least 0.5 pH units removed from the pH of the oil-in-water emulsion. Furthermore, amphiphilic recombinant collagen-like polymers are provided for use in oil-in-water emulsions. The amphiphilic polymers are polar at one end as a result of a relative abundance of polar amino acids, and apolar at the other end as a result of a relative abundance of apolar amino acids.
