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.
Claims9
A self-locking nut comprising:
- a main-nut body having a front surface leading into an interior threaded bore forming x turns of an internal thread therein and a recess in the front surface, the front surface extending along an outer perimeter of the main-nut body, the recess leading into the interior threaded bore;
- and
- a deformable-nut body having a central body portion defining an interior threaded bore forming y turns of an internal thread therein and an outer flange extending outwardly from the central body portion, wherein the deformable nut body includes an inclined front face and an inclined rear face such that the central body portion is thicker than the outer flange,
- wherein the outer flange of the deformable-nut body is fixed to the front surface of the main-nut body such that a relief space is formed between the deformable-nut body and the main-nut body,
- wherein a first portion of the deformable-nut body is contained in the recess prior to installation of the self-locking nut on a threaded bolt shaft, and a second portion of the deformable-nut body is adapted to be contained in the recess after the installation, the second portion having a larger volume than the first portion.
