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.
Claims5
An apparatus for bonding a bearing on an annular member comprising
- a cover plate having a single bore formed centrally therethrough,
- a support plate spaced axially downwardly from said cover plate,
- fastening means extending through said cover plate and releasably attached to said support plate for releasably attaching said cover and support plates together,
- single funnel means attached to said cover plate to extend through the bore formed centrally therethrough and communicating internally of said apparatus for communicating a meltable material therein, and
- a non-metallic core mounted on said support plate to extend upwardly therefrom in close proximity to and below a lower end of said funnel means to define a space therebetween which extends laterally beyond a lower end of said funnel means.
