Abstract

A bearing housing for use in a wind turbine is provided. Further, the bearing housing is axially coupled to a base support structure using plurality of fastening points on the bearing housing. The bearing housing may be coupled to the base support structure at multiple points so that the load is distributed evenly to the support structures such as base plate and the tower. The bearing housing is coupled to the base support structure using a fastener. The horizontal central axis of the bearing housing coincides with the horizontal central axis of the base support structure.

First claim

I claim:

1. A bearing housing for use in a wind turbine, wherein the bearing housing is adapted to accommodate a bearing assembly, the bearing assembly comprising an inner ring and an outer ring;
wherein the bearing housing is axially coupled to a base support structure at a plurality of fastening points on a rim of the bearing housing using a plurality of fasteners, wherein the base support structure has a cylindrical profile, wherein a horizontal central axis of the bearing housing coincides with a horizontal central axis of the base support structure.

2. The bearing housing in accordance with claim 1 , wherein the fasteners are at least one of a weld, a bolt and a magnet.

3. The bearing housing in accordance with claim 1 , wherein the bearing housing is a monolithic component.

4. The bearing housing in accordance with claim 1 , wherein the plurality of fastening points are selected such that the stress distribution to at least one underlying support structure is even.

5. The bearing housing in accordance with claim 4 , wherein the underlying support structure is at least one of a base and a tower portion of the wind turbine.

6. The bearing housing in accordance with claim 1 , wherein the bearing housing is composed of at least one of cast iron, an alloy and a composite material.

7. A wind turbine comprising the bearing housing in accordance with claim 1 .
