Problems solved by technology

The method approach described is less suitable for engineering plants or installations in which the dismantling of components or component connections is not only associated with high costs, but is also already engineering-intensive for the operation of the engineering plant or installation or possibly even disadvantageous
This applies in particular to support members for rotating parts or to rotating members; especially in support members on the basis that said support members are smooth in operation and that dismounting and subsequent reinstallation are more likely to be difficult for equipment or detrimental to the continued operation of the plant

Embodiment Construction

[0028] figure 1 A wind energy installation 1000 is shown with a tower 1 , a nacelle 2 and a rotor 3 ; the rotor has three rotor blades 3 . 1 , 3 . 2 , 3 . 3 . The rotor blades are connected to the figure 1 The details are shown on the hub 5, which drives a generator 7 to generate electricity. Exemplarily, figure 1 Detail (A) shows the mounting of the rotor blade 3 . 1 on the hub 5 . The rotor blade 3 . 1 is connected via a blade carrier 8 to a hub adapter 9 . An embodiment of the connection is in the following Figure 2 to Figure 12 explained in detail.

[0029] figure 2For this purpose, illustration (B) shows, by way of example, a blade flange 30 for the first blade 3 . 1 , which according to this refinement forms the holder as the first component. Furthermore, a row of connections 20 in the form of a plurality of bolts can be seen on the blade flange. The connectors 20 are arranged in concentric circumferential rows along the blade flange 30 . figure 2 Detail in A...

Abstract

The invention relates to a monitored component connection with a first component forming a retaining part, a second component forming a mating part, a connection part that retains the second component on the first component in the connected state, wherein the connection part engages in a connecting recess in said mating part. According to the invention, in order to monitor for inadvertent weakening of the component connection in the connected state, a test pressure can be applied to the connecting recess, and said test pressure can be monitored for a fault deviation that is sufficient for indicating a connection weakening of the component connection in the connected state.

Description

technical field [0001] The invention relates to a monitored component connection according to the preamble of claim 1 and to a wind energy installation. Furthermore, the invention relates to a method for monitoring a component connection for an undesired connection weakness in the connected state of the component connection. Background technique [0002] In principle, it is known to inspect and test components or component connections subjected to special loads separately after they have been disassembled. If the component or the component connection is functional, it is reinstalled in the plant or other engineering installation after such a test or inspection. The method approach described is less suitable for engineering plants or installations in which the dismantling of components or component connections is not only associated with high costs, but is also already engineering-intensive for the operation of the engineering plant or installation Or possibly even disadvan...
