Abstract
A grommet assembly for mounting to a component of a turbine engine is provided. In one exemplary aspect, the grommet assembly includes a grommet that is removably mounted within a pass-through opening defined by the component. The component may be formed of a composite material. A locking member may be mounted to a body of the grommet. A flange projects from the body. When the grommet is mounted to the component and the locking member is mounted to the body, the body is received by the pass-through opening of the component and the locking member is mounted to the body such that the locking member and the flange clamp the component to secure the grommet to the component. An interface member, such as a pin, may be received by a hole defined by the grommet.
Claims20
A grommet assembly, comprising:
- a grommet removably mounted to a component defining a pass-through opening, the grommet having a body extending between a first end and a second end and defining a hole, a flange projecting from the body at or proximate the first end and extending circumferentially around at least a portion of the hole;
- and
- a locking member removably mounted to the body;
- wherein when the grommet is mounted to the component and the locking member is mounted to the body, the body of the grommet is received within the pass-through opening of the component and the locking member is mounted to the body such that the locking member and the flange clamp the grommet to the component;
- wherein the flange extends circumferentially less than three hundred sixty degrees around the hole.
An interface assembly, comprising:
- a component having a first surface and a second surface spaced from the first surface, the component defining a pass-through opening extending between the first surface and the second surface;
- a grommet assembly, comprising:
- a grommet having a body extending between a first end and a second end and defining a hole for receiving an interface member, the body having an interface portion and a threaded portion, the grommet further having a flange projecting from the interface portion of the body at or proximate the first end, the flange extending circumferentially less than three hundred sixty degrees around the hole;
- and
- a locking member removably mounted to the threaded portion of the body.
An interface assembly, comprising:
- a component formed of a ceramic matrix composite (CMC) material and having a first surface and a second surface spaced from the first surface, the component defining a pass-through opening extending between the first surface and the second surface;
- an interface member formed of a metallic material;
- and
- a grommet assembly, comprising:
- a grommet formed of a metallic material and having a body extending between a first end and a second end, the body having an interface portion defining a hole for receiving the interface member, the body also having a threaded portion extending from the second end to the interface portion, the grommet further having a flange projecting radially from the interface portion of the body at or proximate the first end, the flange extending circumferentially less than three hundred sixty degrees around the hole;
- and
- a locking member removably mounted to the threaded portion of the body;
- wherein when the interface portion of the body is received within the pass-through opening of the component and the locking member is threaded onto the threaded portion of the body, the locking member and the flange clamp the grommet to the component.
