Fastener with anti-rotation clip
First Claim
1. A fastener comprising:
- an internally threaded nut having a front surface, a rear surface and a first lock structure that is disposed between the front and rear surfaces;
a clip having a body, a second lock structure and an engagement member, the body defining an internal aperture, the second lock structure being coupled to the body and engaged to the first lock structure to axially retain the clip to the internally threaded nut, the engagement member extending into the internal aperture in the body and being adapted to be received into a keyway in a shaft to inhibit rotation between the clip and the shaft;
a first engagement feature coupled to one of the internally threaded nut and the clip, the first engagement feature comprising at least one tooth; and
a second engagement feature associated with the other one of the internally threaded nut and the clip, the second engagement feature being engaged with the first engagement feature to thereby inhibit relative rotation between the internally threaded nut and the clip.

Abstract
A fastener with a threaded nut, a clip, a first engagement feature and a second engagement feature. The nut has front and rear surfaces and a first lock structure that is disposed between the front and rear surfaces. The clip has a body, which defines an aperture, a second lock structure and an engagement member. The second lock structure is coupled to the body and engages the first lock structure to axially retain the clip to the nut. The engagement member extends into the aperture in the body. The first engagement feature is coupled to either the nut or the clip and comprises at least one tooth. The second engagement feature is associated with the other one of the nut and the clip and is engaged with the first engagement feature to inhibit rotation between the nut and the clip.

13. A fastener comprising:
-
a first structure defining an internally threaded aperture, the first structure having a front surface, a rear surface, a frusto-conical surface, a lock structure and a plurality of teeth, the lock structure being disposed between the front and rear surfaces, the frusto-conical surface being disposed forwardly of the lock structure, the teeth being integrally formed with a remainder of the first structure, the teeth being located on the first structure on a side of the lock structure opposite the rear surface and extending in a direction away from the rear surface; and a second structure having a body, a plurality of spring tabs, an engagement member and an engagement feature, the body defining an internal aperture, the spring tabs being engaged to the lock structure to axially retain the second structure to the first structure, the engagement member extending into the internally threaded aperture and being adapted to be received into a keyway in a shaft to inhibit rotation between the clip and the shaft, the engagement feature being engaged with the teeth on the first structure to thereby inhibit relative rotation between the first and second structures; wherein the frusto-conical surface is configured to urge the plurality of spring tabs radially outwardly as the second structure is pushed onto the first structure; and wherein the first structure comprises a hub member and an internally threaded member. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
