AI Technical Summary

Problems solved by technology

This is difficult or impossible for many fastener arrangements
Security wires can be used in more situations, but are impractical for very large, high-load fasteners
Additionally, proper installation of the safety wire requires considerable skill and can be difficult to perform with hard-to-reach fasteners

Embodiment Construction

[0041] The examples described below involve locking the rotational position of a fastener component that can rotate about an axis relative to a structural member. In each of the examples described, the locking is facilitated by a locking device that includes a rigid locking member. The exemplary locking members described herein each have a first end and a second end, the first end being configured to engage a fastener component such that the fastener component is substantially prevented from being relative to the first end The second end is configured to engage with the structural member such that rotation of the locking member relative to the structural member is substantially prevented. In some instances, it may be considered that the first end is fixedly attached to the fastener component when the first end is engaged with the fastener component, and it may be considered that when the second end is engaged with the structural member The second end is fixedly attached to the...

Abstract

The invention provides a locking apparatus for locking the rotational position of a fastener component which is rotatable about an axis relative to a structure. The locking apparatus includes a rigidlocking member having a first end configured to engage with the fastener component such that rotation of the fastener component relative to the first end is substantially prevented, and a second end configured to engage with the structure such that rotation of the locking member relative to the structure is substantially prevented. The invention also provides an assembly comprising a fastener anda locking apparatus, and a method for locking the rotational position of a rotatable fastener component.

Description

Technical field [0001] The invention relates to a locking device for locking the rotational position of a fastener component that can rotate about an axis relative to a structural member, relates to an assembly including a fastener and a locking device, and also relates to a locking device The method of the rotation position of the firmware component. Background technique [0002] Rotatable fastener components such as nuts and bolts may loosen when subjected to vibration. Fasteners on vehicles, such as aircraft, may experience significant vibration during operation of the vehicle, so it is desirable to provide a mechanism for locking the rotational position of such fasteners. The known locking mechanism includes a cotter pin and a safety wire. The cotter pin is suitable for locking two relatively rotatable parts of a fastener (such as a nut and a bolt) together. The safety wire is attached at one end. Attached to one rotatable fastener part and to another part of the fastener o...
