Abstract
An annular bronze bearing is bonded to a cylindrical inner surface of a metallic member by positioning the member in a fixture to define an annular chamber therein, communicating a charge of bronze alloy particles to the chamber via an open end thereof, melting the alloy and cooling the member and alloy to form the bearing. The apparatus comprises a pair of plates adapted to clamp the metallic member therebetween to define the annular chamber between the member and a cylindrical core. A ceramic funnel is secured on the upper one of the plates to communicate the melted bronze alloy particles to the annular chamber via the open end thereof.
Claims8
A method for bonding an annular bearing on a cylindrical surface of a metallic member comprising the steps of
- positioning said metallic member in a fixture to define an annular chamber closed at a first end and open at a second end thereof,
- placing a charge of a metallic bearing alloy in particle form adjacent to and in communication with the open end of said annular chamber in a predetermined quantity sufficient to at least substantially fill said chamber,
- melting said bearing alloy and at least substantially filling said annular chamber therewith by gravity flow, and
- cooling said metallic member and said melted bearing alloy to ambient temperature to form a solidified annular bearing, conforming to the shape of said annular chamber, bonded to said metallic member.
