Definitions
- the invention relates to an elastomeric bearing for reducing vibrations in machines, which are mainly caused by externally applied forces. Due to its special design and construction symmetry, it can process the forces occurring in all spatial directions while optimally protecting the material.
- the bearing according to the invention is preferably suitable for a circular connection of rotor-gear units with the machine frame in wind turbines.
- the system allows a perfect power transmission, but still has the following disadvantage:
- a torsional moment about the rotor shaft axis which is transmitted from all camps each by a radial force in these camps - the radial force engages in the cone elements (10) in the middle of the respective cone bearing, so that the resulting radial force acts approximately in the middle between the two cones (8, 9).
- the transmission of this moment via the
- the invention thus provides an elastic machine or gearbox bearing for transmitting in all spatial directions, in particular axially and radially occurring forces and moments and for the reduction or isolation occurring vibrations, which an axially aligned elastomeric sandwich element (5) and mounted above or below it elastomeric cone element (3) whose axis is oriented perpendicular to the sandwich element (5) and whose tapered end is positioned opposite this sandwich element (5), the elements (3) and (5) being constituted by a cone piece (4) which differs from the cone element (4) Cone member (3) is centrally enclosed, and a cylindrical piece (4a), which is surrounded by the sandwich element (5) centrally, communicate with each other, and each of the elements (3), (5), (4) (4a) a have concentric axially aligned bore for receiving a clamping bolt or a clamping screw (7) for clamping one between the elastomeric Elements (3) and (5) introduced usually acting as a clamping flange machine part (2) with the mounted below the element (3) acting as a mounting f
- the elastic force transmission torque according to the invention now consists of an elastic cone element (3) and one with this axially strained elastic sandwich element (5). While the cone element (3) transmits axial forces and radial forces, the sandwich element (5) transmits almost exclusively axial forces.
- the resulting total force which acts on the bearing according to the invention, now engages in the region of the conical piece (4) with widened cross-section, so that the resulting bending moment no longer on the narrow Connecting piece (4a) or the clamping means (7) acts and leads to a loosening of the attachment or to a material fatigue.
- the stiffness of the sandwich element (5) according to the invention by about the factor 2 - 100, preferably 10 - 100, in particular 50 - 100 lower than the radial stiffness of the cone element (3).
- taper piece (4) and mounting flange (1) may also be integral components of a single component in one embodiment of the invention.
- cone piece (4) and the cylinder piece (4a) can be a single workpiece.
- Both elements are thus clamped together in the axial direction. Both elements can have the same rigidity in the axial direction, but this is not absolutely necessary. However, the cone element (3) has a significantly higher rigidity in the radial direction than the sandwich element (5).
- the biasing and the axial force transmission takes place in the sandwich element preferably via a pressure plate (6), which is provided with a bore which can receive the clamping bolt or the clamping screw (7).
- the invention thus relates to a corresponding bearing which has a pressure plate which rests directly or indirectly on the sandwich element (5). - -
- the pressure plate (6) and the sandwich element (5) form a structural unit.
- the distribution of forces on the entire bearing element is particularly advantageous if the solid inelastic conical cone piece (4) is not formed by a simple conical surface, but has a convex curvature.
- the effect can be further enhanced if, moreover, the elastomeric cone element (3) is correspondingly concavely curved on the inside and preferably also on the outside, so that its inner surface can fit precisely on the outer surface of the cone piece (4).
- the cone piece (4) can form a structural unit with the cylinder piece (4a).
- the subject of the invention is a corresponding bearing in which the cone piece (4) has a convexly curved surface on which the inner surface of the cone element (3) rests.
- the components (3) and (4) can be combined into a single structural unit according to the invention in a further embodiment.
- the subject matter of the invention is also a corresponding bearing in which the inner surface of the cone element (3) is concavely curved, and preferably also in addition the outer surface of the cone element (3) is concavely arched.
- the elastomer elements (3) and (5) have 1 or more elastomer layers. In general, they consist essentially of at least two elastomer layers, which are separated by a rigid intermediate layer, usually a metal plate. Preferably, the elements consist of three to five elastomeric layers with corresponding intermediate plates or layers. The elements are closed to the outside by also stiff layers / plates.
- the elastomeric materials used for the bearings of the invention consist essentially of a natural rubber, a natural rubber derivative or a suitable elastic polymeric plastic or plastic mixture.
- the elastomer layer according to the invention may have different hardness ("Shore hardness") and different damping properties, according to the desired requirements. Elastomers having a hardness of 20 to 100 Shore A, in particular 30 to 80 Shore A, are preferably used. The preparation of such elastomers of different hardness is known in the art and adequately described in the relevant literature.
- the rigid intermediate plates or layers are made according to the invention of materials with high rigidity, high strength and low compressibility.
- these are metal sheets, but other materials such as hard plastics, composites or carbon fiber-containing materials are used.
- the intermediate sheets and the elastomeric materials are usually bonded together during vulcanization.
- the cone element (3) of the bearing according to the invention should have a cone angle of 10 - 50 ° with respect to the machine axis (a) or to the axis of the clamping element (7) opposite or in the screwing. Preferably, it has a cone angle of 25-50 °.
- the bearing according to the invention can be used in many different ways. It is particularly suitable as a so-called flying storage for wind turbines, in particular to produce a circumferential elastic connection between the rotor shaft, the transmission or a rotor-gear unit and the machine frame.
- the bearing according to the invention can also be used as a turbine coupling in wind power plants, as described in EP 1 065 374 B1, which additionally leads to a simplification.
