Abstract
In one embodiment, a system includes a generator frame that includes a spring ring configured to mount removably between an outer annular support and a stator. The spring ring includes a first guide configured to circumferentially align the spring ring to the outer annular support, and a second guide configured to circumferentially align the spring ring to the stator.
Claims20
A system, comprising:
- a generator, comprising:
- a rotor;
- a stator disposed about the rotor;
- and
- a framework disposed about the stator, wherein the framework comprises:
- an outer annular support;
- an outer axial bar coupled to the outer annular support;
- an inner axial bar coupled to the stator;
- a spring ring disposed radially between the outer axial bar and the inner axial bar, wherein the spring ring is removably coupled to the outer axial bar via a first guide configured to align the spring ring to the outer annular support, the spring ring is removably coupled to the inner axial bar via a second guide configured to align the inner axial bar with the stator, and the second guide comprises first removable fasteners configured to engage the inner axial bar to removably couple the inner axial bar to the spring ring.
