Abstract
An improved stabilizer is disclosed. In the preferred and illustrated embodiment, a built-up spline is disclosed. The spline is made by drilling a set of holes in a blank of relatively soft metal and inserting hardened inserts into the metal. Typical inserts are made of tungsten carbide. They may be brazed on the back side to firmly affix the inserts in holes drilled in the metal strip. The metal strip is welded to the stabilizer body. It has the advantage in that it can be refaced or built up after wear.
Claims8
A method of fabricating a splined stabilizer comprising the steps of:
- (a) forming an opening completely through a metal spline body which opening extends from a front or outer face and intersects a back face of said body;
- (b) positioning an insert of material in said opening which insert is harder than the metal of said metal spline body;
- (c) joining said insert to said spline body at said back face by means of a brazing material;
- and
- (d) thereafter joining said spline body to a stabilizer body with the back face of said spline body against the stabilizer body.

A method of fabricating a splined stabilizer comprising the steps of:
- (a) forming a plurality of openings in a metal spline body which openings extend from a front or outer face to a back face of said body;
- (b) positioning inserts of material in each of said openings which inserts are harder than the metal of said metal spline body;
- (c) joining said inserts to said spline body by:
- (1) first positioning unjoined inserts in the openings wherein the openings extend fully through the spline body;
- (2) applying an unbonded braze material over the full back face of said spline body adjacent to the openings and inserts;
- and
- (3) heating said braze material to melt said braze material sufficiently to bond said inserts to said spline body;
- and
- (d) thereafter joining said spline body to a stabilizer body with the back face of said spline body against the stabilizer body.
