Abstract
A bearing bush for movably holding a generator-side component and a foundation-side component of a wind turbine may include an elastomer body having a cavity for receiving a foundation-side or generator-side bearing bolt defining a longitudinal direction, and a tensioning assembly adapted to compress the elastomer body on both sides in the longitudinal direction in such a way that it exerts a pretensioning force directed in the longitudinal direction on both sides of the elastomer body when compressing the elastomer body.
Claims21
A bearing bush adapted to movably hold a generator-side component and a foundation-side component of a wind turbine, the bearing bush comprising:
- an elastomer body having a cavity adapted to receive a foundation-side or generator-side bearing bolt defining a longitudinal direction;
- and
- a tensioning assembly adapted to compress the elastomer body on both sides in the longitudinal direction such that, in response to a compressing of the elastomer body, the tensioning assembly is adapted to exert a pretensioning force directed in the longitudinal direction on both sides of the elastomer body.
A bearing bush adapted to movably hold a generator-side component and a foundation-side component of a wind turbine, the bearing bush comprising:
- an inner elastomer body adapted to be support on a foundation-side or generator-side bearing bolt defining a longitudinal direction;
- an outer elastomer body adapted to be supported on the foundation-side or generator-side component;
- and
- a tensioning assembly with a support bush arranged between the inner elastomer body and the outer elastomer body and supported on both the inner elastomer body and the outer elastomer body, wherein the tensioning assembly is adapted to compress at least one of the inner elastomer body and the outer elastomer body in the longitudinal direction.
A bearing bush adapted to movably hold a generator-side component and a foundation-side component of a wind turbine, the bearing bush comprising:
- an elastomer body with a cavity adapted to receive a foundation-side bearing bolt or a generator-side bearing bolt, defining a longitudinal direction;
- and
- a tensioning assembly adapted to compress the elastomer body in the longitudinal direction, wherein the elastomer body has a stiffness which varies in the longitudinal direction.
