Abstract
A locking plate for restricting rotation of a fastener connecting a first component of a gas turbine engine and a second component of a gas turbine engine includes a base having a planar surface receivable in overlapping arrangement with a head of the fastener. A locking portion extends from the base. Engagement between the locking portion and the first component restricts rotation of the locking portion. A key extends from the base and is connectable to the fastener such that the fastener is not rotatable relative to the key when the locking portion has engaged the first component.
Claims9
An interface comprising:
- a first component including a bracket having a first hole formed therein;
- a second component including a link coupled to a spherical bearing, the spherical bearing having a second hole formed therein, the second component being positioned adjacent the first component such that the first hole and the second hole are axially aligned;
- a fastener positioned within the first hole and the second hole to couple the first component to the second component, the fastener including a head having a wrenching feature formed therein;
- and
- a locking plate receivable in overlapping arrangement with the fastener, the locking plate including a first portion connectable to the fastener and a second portion configured to cooperate with the first component to restrict rotation of the locking plate about the longitudinal axis of the fastener, wherein the first portion of the locking plate includes a key, the key being receivable within the wrenching feature to rotatably couple the locking plate to the fastener.
