Abstract
In one embodiment, a system includes a stator mounting kit that includes multiple radial adjustment shims having different thicknesses from one another. The stator mounting kit also includes multiple stator alignment adapters having different circumferential alignments between a keybar mount and a spring bar mount. The stator mounting kit is configured to enable radial and circumferential alignment between each spring bar and respective keybar in a stator framework via selection of one of the stator alignment adapters and selection of one or more of the radial adjustment shims.
Claims14
A system, comprising:
- a generator, comprising:
- a rotor having a rotational axis;
- a stator disposed about the rotor;
- and
- a framework disposed about the stator, wherein the framework comprises:
- an outer annular support;
- a spring bar coupled to the outer annular support, wherein the spring bar is aligned with the rotational axis;
- a keybar coupled to the stator, wherein the keybar is aligned with the rotational axis;
- an alignment adapter disposed radially between the spring bar and the keybar, wherein the alignment adapter comprises outer and inner recesses disposed radially opposite from one another relative to the rotational axis, the outer recess is configured to hold the spring bar, the inner recess is configured to hold the keybar, and the alignment adapter is configured to align the keybar to the stator in a circumferential direction via a circumferential position of the outer recess relative to the inner recess;
- wherein the inner recess is circumferentially off-center relative to the outer recess by a circumferential offset.

A system, comprising:
- a stator mounting system, comprising:
- a plurality of spring bars configured to mount to an annular frame in a first circumferentially spaced arrangement about a longitudinal axis of the annular frame;
- a plurality of keybars configured to mount to a stator in a second circumferentially spaced arrangement about the longitudinal axis;
- and
- an H-beam positioned radially between each spring bar and each keybar, each H-beam is configured to block circumferential movement of the respective keybar relative to the respective spring bar, and each H-beam is selectable from a plurality of H-beams having different alignment dimensions configured to facilitate circumferential alignment of the respective keybar relative to the respective spring bar;
- wherein each H-beam comprises a first cavity on a radially inward surface and a second cavity on a radially outward surface, the first cavity is configured to hold a respective keybar in a circumferential direction, the second cavity is configured to secure a respective spring bar in the circumferential direction, wherein the first cavity is circumferentially offset from the second cavity by an offset distance.
