Abstract
A drive arrangement for a wind turbine includes a main shaft, a housing, and a nacelle-mounted support structure. The main shaft of the drive arrangement for the wind turbine is completely supported in the housing. The housing of the drive arrangement for the wind turbine is at least partially resiliently mounted in the support structure.
Claims15
A drive arrangement for a wind turbine, comprising:
- a main shaft;
- a housing;
- a nacelle-mounted support structure;
- and
- a first elastomer and a second elastomer of different hardness,
- wherein the main shaft is fully supported in the housing,
- wherein the housing is fully resiliently mounted in the support structure,
- wherein the first elastomer is disposed in a radial intermediate space between the housing and the support structure, and
- wherein the second elastomer is disposed in an axial intermediate space between the housing and the support structure.
6 more elements
A drive arrangement, comprising:
- a main shaft;
- a housing structure with housing structure eye openings,
- wherein the housing structure surrounds the main shaft, and
- wherein the main shaft is supported in bearings arranged within the housing structure;
- a nacelle-mounted support structure with support structure eye openings;
- one or more bolts configured to extend through one or more of the housing structure eye openings, respectively, and one or more pairs of the support structure eye openings, respectively, such that the housing structure is mounted to the support structure via the one or more bolts;
- and
- at least two spring elements arranged such that:
- the at least two spring elements are in at least two of the housing structure eye openings, respectively, such that each spring element is between a corresponding bolt of the one or more bolts and the housing structure, or
- the at least two spring elements are in at least two of the support structure eye openings, respectively, such that each spring element is between a corresponding bolt of the one or more bolts and the nacelle-mounted support structure,
