Abstract
A bushing utilizes a fabric reinforced thermoset composite sleeve incorporated within an outer shell in a construction enabling the sleeve to be press-fitted within the shell and held therein by a constriction in the shell bore which is embraced by the bearing liner. Following installation of the bearing sleeve, the sleeve bore may be reamed to provide a uniform inside diameter.
Claims9
A bushing comprising, in combination:
- an outer shell having an inner cylindrical surface interrupted by a radially inwardly displaced wall portion;
- an inner bearing sleeve disposed within the shell in a press-fit relationship and overlying the inwardly displaced wall portion;
- that portion of the inner bearing sleeve overlying the inwardly displaced wall portion being of a sufficiently reduced wall thickness to provide a constant inside diameter for the inner bearing sleeve;
- and
- the inside diameter of the inner bearing sleeve sized to provide a smooth running fit between the inner sleeve and a shaft extending through and supported in the bushing.

The method of making a bushing comprising:
- providing a relatively rigid shell having a cylindrical bore interrupted by a radially inwardly displaced wall portion forming a constriction in such bore;
- providing a resilient bearing sleeve sized to be press fitted into said bore;
- pressing said sleeve axially into said sleeve bore and beyond said constriction and causing the sleeve to embrace the constriction;
- and
- reaming the sleeve bore to provide a uniform internal diameter.
