Abstract
The present invention provides a method of repairing a bearing bore defined by an inner surface of a bearing housing, for instance a bearing housing that is part of a wind turbine. The method includes applying a liquid resin to at least part of the inner surface of the bearing housing. The method includes mounting a bore insert in the bearing bore, where the bore insert includes an arcuate portion having an edge positioned along a line of required radius of the bearing bore, so that the liquid resin fills a gap between the inner surface of the bearing housing and the edge of the arcuate portion of the bore insert. The method includes removing the bore insert from the bearing bore after the liquid resin has solidified to repair the bearing bore to the required radius. Advantageously, the invention provides a relatively simple and inexpensive method for repairing a bearing bore that has suffered wear, that may be performed on-site and which obviates the need for potentially expensive component replacement of the bearing housing.
