Definitions

  • ABSTRACT Bimetallic bearing material comprising aluminum alloys consisting of silicon, cadmium, copper, magnesium, and the balance aluminum, bonded directly on steel backings, are heat treated to efi'ect improved hardness and fatigue resistance.
  • the heat treatment comprises solution heating said bearing material at temperatures ranging from 900 F. to 975 F. for at least 15 seconds but not exceeding 80 seconds, after which it is rapidly quenched in a fluid medium having a maximum temperature of 100 F., followed by precipitation heat treatment at about 350 F. for ten hours.
  • the present invention relates to a bearing comprising aluminum alloy directly bonded on a steel backing. More specifibearings comprising aluminum alloys directly bonded onto steel supports or backings.
  • the aluminum alloy consists of aluminum having small amounts of silicon, cadmium, copper, and magnesium.
  • the steel backing can be any of a number of low carbon steels.
  • solution heat treatments in the order of five minutes and longer are not necessary. in fact, solution heat treatment in the order of 15 seconds is quite satisfactory for obtaining the desired properties of fatigue resistance and strength. Furthermore, heat treatment of finished bearings may be undesirable because of damage to the finely finished bearing surfaces.
  • Another object of the invention is to provide a heat treatment for hearing material, in strip, blank, or semifinished bearing form, thereby improving the strength and fatigue resistance of the finished bearings.
  • a further object of the invention is to provide high quality bearings suitable for use under high loadings and speed conditrons.
  • steel of the type commercially known as SAE 1010 or 1008 may be used as the material for the backing support, though other steel types may be used.
  • Low carbon steel is preferred because it endures a greater rolling reduction which results in an improved bond. Also, it has lower initial hardness and is less subject to cold working during cladding and forming.
  • the aluminum alloy As to the aluminum alloy, it is directly bonded onto the steel backing to form the bearing material in accordance with the method disclosed in U.S. Pat. No.- 3,300,838, assigned to the same assignee of the present invention.
  • the heat-treatment response of the aluminum alloy is related to the copper and magnesium content, as well as the silicon content.
  • Aluminum alloys having silicon 2-8 percent, cadmium 0.5-4 percent, copper 0.05-15 percent, magnesium 0.1-0.2 percent, and the balance aluminum, have proven very satisfactory and the invention contemplates only alloys having the above compositions.
  • the thickness of the layer of aluminum alloy and/or the overall thickness of the composite structure, i.e., the bearing material depend on the intended use of the finished bearing.
  • the bimetallic bearing material can be treated in strip, blank, or semi-finished bearing form.
  • the steel backed clad aluminum strip is attached to a pulling unit leading into a molten lead bath maintained at temperature ranging from 900 to 975 F., preferably about 950 F.
  • the strip is then pulled out at a speed permitting it to be heated at said temperature range for a minimum time of 15 seconds. Heat-up time takes usually about a minute. Thus, total immersion in the lead bath may take about seconds.
  • a fluid medium such as water or oil having a maximum temperature of l00 F preferably about 75 F.
  • the time between removal from the lead bath to quenching should be such that the temperature of the strip is not allowed to drop below 850 F. Intervals in the order of 30 seconds are usually satisfactory. It should be emphasized that the drop in temperature prior to quenching is of important consideration. The short heating cycle is sufficient to cause the copper, magnesium, and a portion of the silicon to go into solid solution with the aluminum under equilibrium conditions and rapid quenching is necessary to preserve a condition of super saturation.
  • the strip After quenching, the strip is air dried and hardened by precipitation heat treatment at 350 F. for about ten hours in a recirculating air furnace, or other heating means. A minimum hardness of 62 on the Rockwell l5 T-scale is obtained for 0.010 inch thick aluminum alloy liner.
  • the strip is then fabricated into bearings and the bearing surface is machined and plated at the bearing surface with an overlay having thickness of 0.0004 to 0.0006 inches.
  • the overlay comprises generally a high lead alloy having copper and tin.
  • the bimetallic strip may be heat treated in the molten lead bath as described above. After quenching, the bearing strip is cut into bearing blanks which are channelled, and roll-formed into shells. The formed bearings are then hardened by precipitation heat treatment in a recirculating air furnace at about 350 F. for 10 hours to a minimum R T 62 hardness for a 0.010 inch thick alloy liner.
  • molten salt baths Other media for solution heat treatment can be utilized such as molten salt baths.
  • the bimetallic strip can be cut into bearing blanks which are then placed in convenient means such as metal baskets which can be lowered into the molten salt bath having a temperature ranging from 900-975 F.
  • the blanks are then maintained at said temperature for a minimum of 15 seconds excluding heat-up time which is usually about one minute.
  • the blanks are then quenched in a fluid medium such as water (maximum temperature F.). Again, keeping in mind that the interval between removing from the molten salt bath and the quenching is such that the temperature of the blanks does not drop below 850 F. Normally, a delay time of up to 30 seconds is satisfactory.
  • the blanks are then dried and precipitation hardened at about 350 F. for ten hours in a recirculating air furnace.
  • Bearings are then fabricated from the hardened blanks as described hereinbefore.
  • the blanks are channelled and rollformed into shells after the solution heat treatment, then they are precipitation hardened at 350 F., as described.
  • the bimetallic strip is annealed at 650 F. for 30 minutes prior to solution heat treatment.
  • EXAMPLE I DIESEL ROD BEARlNG An aluminum alloy having a composition of 3.94 percent silicon, 1.0 percent cadmium, 0.13 percent copper, 0.14 percent magnesium, and the balance aluminum, was directly bonded onto a steel backing (SAE 1010) having a thickness of 0.085 inches to form a bimetallic strip having a thickness of 0.100 inch.
  • SAE 1010 steel backing
  • the strip was cut into blanks which were heated in a neutral molten salt bath at 950 F. for 65 seconds, 50 seconds were required for heat-up time.

  • DIESEL MAIN BEARING An aluminum alloy having the composition 3.70 percent silicon, 1.l percent cadmium, 0.15 percent magnesium, 0.10 percent copper, and the balance aluminum, was directly bonded onto an SAE 1010 steel backing (0.139 inch thick) to form a bimetallic bearing strip of 0.166 inch thickness.
  • the strip was cut into blanks which were solution heat treated in a neutral molten salt bath at 950 F as done in Example 1. After precipitation hardening at 350 F. for hours, the average hardness of the aluminum alloy layer measured 69 on R T scale. The blanks were then fabricated into bearings having 0.156 inch wall thickness. Hardness of the aluminum alloy liner had an average of 70 on R ,,T scale. Similar to Example I, the bearing was plated with an over-lay (0.0005 inch thick) having the same composition.
  • EXAMPLE III DIESEL FLANGE MAIN BEARING An aluminum alloy having the same composition of Example II was directly bonded on an SAE 1010 steel backing (0.089 inch thick) to form a bimetallic bearing strip having 0.1 19 inch thickness. The strip was cut into blanks which were solution heat-treated, similar to Examples I and II. The quenched blanks were then formed into flange bearing halfshells which were precipitation hardened, as described in the previous examples. The aluminum alloy layer, was found to have an average hardness of 69 on R T scale. The formed shells were then machined to a wall thickness of 0.102 inch, after which an over-lay of about 0.0005 inch was plated on the bearing surface.
