Claims21
A bi-metallic bearing assembly for an associated pump, the bearing assembly comprising:
- a sleeve formed of a first metal, and having at least one opening therein;
- and
- an insert formed of a different, second metal, and received in the sleeve opening;
- wherein the first metal is lighter weight than the second metal.
A method of forming a bi-metallic bearing assembly for an associated pump, the method comprising:
- forming a sleeve formed of a first metal, and having at least one opening therein;
- separately forming an insert formed of a different, second metal, and dimensioning the insert for receipt in the sleeve opening, the first metal being lighter weight than the second metal;
- inserting the insert into the opening of the sleeve;
- and
- mechanically joining the insert to the sleeve.
A bi-metallic bearing assembly comprising:
- a one-piece sleeve having an inner cylindrical opening extending therethrough, the sleeve formed from an aluminum or titanium alloy;
- a liner formed from a leaded bronze or bismuth bronze configured and dimensioned for selectively removable receipt in the sleeve opening;
- a first recess in an outer surface of the liner;
