Abstract

A method of making an axle sleeve includes forming a main body comprising a cylinder and forming an expansion member whereby a diameter of the main body may be varied. The method includes cutting an inner helical cutout comprising a first slit defined through the main body and extending helically from an inner edge of the main body, cutting an outer helical cutout comprising a second slit defined through the main body and extending helically from an outer edge of the main body, forming an inner edge remaining portion comprising an annular section of the main body unbroken by the inner helical cutout, and forming an outer edge remaining portion comprising an annular section of the main body unbroken by the outer helical cutout.

First claim

What is claimed is:

1. A method of making an axle sleeve comprising:
forming a main body comprising a cylinder; and
forming an expansion member whereby a diameter of the main body may be varied, wherein the forming the expansion member further comprises:
cutting an inner helical cutout comprising a first slit defined through the main body and extending helically from an inner edge of the main body;
cutting an outer helical cutout comprising a second slit defined through the main body and extending helically from an outer edge of the main body;
forming an inner edge remaining portion comprising an annular section of the main body unbroken by the inner helical cutout;
forming an outer edge remaining portion comprising an annular section of the main body unbroken by the outer helical cutout;
forming an inner chamfer comprising a portion of a radially innermost face of the main body progressively thinned toward an inner edge of the axle sleeve; and
forming an outer chamfer comprising a portion of a radially innermost face of the main body progressively thinned toward an outer edge of the axle sleeve.

2. The method of making the axle sleeve according to claim 1 , wherein the inner helical cutout extends at a first spiral angle relative to the axle sleeve.

3. The method of making the axle sleeve according to claim 2 , wherein the outer helical cutout extends at a second spiral angle relative to the axle sleeve.
