Abstract
A self-locking nut includes a main-nut body and a deformable-nut body. The main-nut body has a recess leading into an interior threaded bore forming x turns of an internal thread therein. The deformable-nut body has an outer flange and an interior threaded bore forming y turns of an internal thread therein. The outer flange of the deformable-nut body is fixed to the main-nut body such that a relief space is formed between the deformable-nut body and the recess. A ratio of x:y is about 2:1.
Claims23
A self-locking nut comprising:
- a main-nut body having a recess leading into an interior threaded bore forming more than three turns of an internal thread therein;
- and
- a deformable-nut body having an outer flange and an interior threaded bore forming less than three turns of an internal thread therein,
- wherein the outer flange of the deformable-nut body is fixed to the main-nut body such that a relief space is formed between the deformable-nut body and the recess.

A self-locking nut comprising:
- a main-nut body having (i) a front surface, (ii) an opposing back surface, (iii) an outer surface configured to be engaged by a tool to rotate the self-locking nut about a threaded bolt shaft thereby causing the main-nut body to move axially in a first direction towards an object, (iv) an interior threaded bore forming a plurality of turns of an internal thread therein, and (v) a recess in the front surface extending into the main-nut body;
- and
- a deformable-nut body having (i) a front surface configured to engage the object thereby limiting axial movement of the deformable-nut body, (ii) an opposing back surface, (iii) an outer surface, (iv) an interior threaded bore forming at least a portion of a turn of an internal thread therein, and (v) an outer flange;
- wherein the outer flange of the deformable-nut body is attached to the front surface of the main-nut body such that a relief space is formed between a portion of the opposing back surface of the deformable-nut body and the recess, the relief space providing an area for the deformable-nut body to deform into during installation of the self-locking nut on the threaded bolt shaft.

A self-locking nut comprising:
- a main-nut body having a recess leading into an interior threaded bore forming x turns of an internal thread therein;
- and
- a deformable-nut body having an outer flange and an interior threaded bore forming y turns of an internal thread therein,
- wherein the outer flange of the deformable-nut body is fixed to the main-nut body such that a relief space is formed between the deformable-nut body and the recess, and wherein x is greater than y.
