Elastomer components that can be pre-stressed by pressure means, and method for the production thereof

摘要

Elastomer components, which are to have an elastomer volume with a sufficiently large prestress, as is required, for example, for use in wind energy plants. The elastomer components are substantially based on the incorporation and integration of separating elements into the elastomer body of the component, the elements are disposed either individually or in structures. The body may be compressed by pressure supplied into the region, between the separating elements and the surrounding elastomer material, or directly into the separating elements, such that the elastomer components are prestressed in a dynamically adjustable manner.

主权项

1. A pre-stressable elastomer component comprising:
first and second plates being formed as one of cylindrical shells, conical shells, cylindrical half-shells, conical half-shells, cylindrical shell segments and conical shell segments, the first and the second plates being aligned and defining a central axis such that the elastomer component is in a form of at least one of a bush, a half-bush and a bush segment; at least one elastomer layer that is entirely formed between the first and the second plates and radially spaced from the central axis; at least one separating element is completely encased by the elastomer layer in an interior thereof; at least one pressure-resistant supply line with a valve, the supply line with the valve passes into the elastomer layer and communicates with the at least one separating element such that, on supplying a pressure media, via the supply line with the valve, chambers form in a region of the at least one separating element due to the surrounding elastomer layer being forced apart, when the chambers are filled with the pressure media and expanded, the surrounding elastomer layer is squashed, and the elastomer component is pre-stressed, and the chambers are entirely radially spaced from the central axis.
