Definitions
- the present invention is made of a Cu-Ni-based sintered alloy having excellent wear and corrosion resistance and high strength, and is therefore particularly suitable for downsizing and lightening of a motor type fuel pump. Is related to bearings that exhibit excellent wear resistance over a long period of time. Background art
- a rotating shaft fixed to both ends of a motor is supported by bearings in a casing, an impeller is inserted into one end of the rotating shaft, and A structure in which a gasoline flow passage having a narrow gap is formed along an outer peripheral surface of the impeller, a motor, and a gap (not shown) between the bearing and the rotating shaft;
- the impeller rotates, and gasoline is taken into the casing by the rotation of the impeller, and the taken gasoline is formed along the impeller, the outer peripheral surface of the motor, and the gap (not shown) between the bearing and the rotating shaft.
- the gas is sent out through the gasoline flow passage and then fed into a separate gasoline engine.
- a small amount of fuel passes through the outer periphery of the two bearings, and gasoline pressurized by the impeller passes through a fuel passage of a casing (not shown).
- Patent Document 1 Through the armature to the outer surface.
- various high-strength Cu Sintered alloys are used (see, for example, Patent Documents 1, 2, and 3).
- the Cu-based sintered alloy bearing used in the motor-type fuel pump with the above structure is required. Although both have high strength, they do not have sufficient abrasion resistance, so wear progresses quickly, and the wear progress is caused by the fact that the liquid fuel contains sulfur and its compounds as impurities. In some cases, this will be further accelerated, and as a result, the service life will be short in a relatively short time.
- the present inventors have conducted research to develop a bearing suitable for use in a motor-type fuel pump that is reduced in size and operated at a high speed.
- the mass of the bearing of the fuel pump is expressed by mass% (hereinafter,% means mass%), graphite: 1 to 5%, Cu—P alloy containing 5 to 10% P: 2 to 9%, Ni Cu—Ni alloy containing 21 to 26% by weight: a sintered compact of a compact having the following composition: As shown in the schematic view of the micrograph of the microstructure, the porosity is dispersed and distributed at a rate of 8 to 18% in the matrix of the Cu—Ni alloy grains, and the Cu—Ni alloy grains are dispersed.
- the resulting bearing made of a Cu—Ni-based sintered alloy enables its size and thickness to be reduced, and has excellent wear resistance under the environment exposed to the high-pressure, high-speed flow of liquid fuel.
- the research results showed that it exhibited excellent corrosion resistance and also exhibited excellent corrosion resistance against liquid fuels containing sulfur and its compounds as impurities. Disclosure of the invention
- the present invention has been made based on the above research results, and has a graphite of 1 to 5%,
- the present invention has a feature in a wear-resistant bearing of a motor-type fuel pump made of a Cu—Ni-based sintered alloy having a P component and a structure in which free graphite is distributed in pores.
- the Cu-Ni alloy has excellent wear resistance and corrosion resistance as described above. After sintering, it forms a base made of Cu-Ni alloy grains, and the bearing itself has excellent wear and corrosion resistance. However, if the content of Ni in the total amount with Cu is less than 21%, it is not possible to ensure excellent wear resistance and corrosion resistance of the bearing. Similarly, when the content exceeds 26%, the sinterability rapidly decreases, and a reduction in strength cannot be avoided. Therefore, the content ratio is set to Ni: 21 to 26%.
- the P component of the Cu-P alloy is located between the Cu-Ni alloys during sintering and improves the sinterability between them, and is thus composed of Cu-Ni alloy grains.
- the Cu—P alloy accounts for less than 2% of the total, it is not possible to secure sufficient bonding strength between Cu—Ni alloy grains, causing a drop in strength. If the content exceeds 9%, it is inevitable that the strength of the grain boundary of the Cu—Ni alloy is reduced, so the total ratio is set to 2 to 9%.
- Graphite is present as free graphite mainly in pores dispersed and distributed in the base material, imparts excellent lubricity to bearings, and thus contributes to improving the wear resistance of bearings, but its content is less than 1% In this case, the desired improvement effect cannot be obtained in the above-mentioned action.
- the content ratio exceeds 5%, the strength rapidly decreases. Therefore, the content ratio is set to 1 to 5%.
- the pores dispersed and distributed in the matrix of the Cu-Ni alloy grains reduce the strong friction and high surface pressure that the bearing receives under high-pressure, high-speed flow of liquid fuel, and thus significantly reduce bearing wear.
- the porosity is less than 8%, the proportion of porosity distributed in the base material is so small that the effect cannot be sufficiently exerted, while the porosity is 18%. Beyond that, the strength of the bearing suddenly decreases, so the porosity was set to 8 to 18%.
- FIG. 1 is a schematic view of a micrograph (magnification: 200) of the bearing 3 of the present invention by an optical microscope.
- FIG. 2 is a schematic cross-sectional view of a motor fuel pump for a gasoline engine.
- a Cu—Ni alloy having a predetermined average particle size in the range of 30 to 100 im ( ⁇ : 1 content ratio is shown in Tables 1 and 2)
- Powder, graphite powder, Sn powder, Co powder, Fe powder, and Cu powder are prepared, and these raw material powders are shown in Tables 1 and 2.
- each is composed of a Cu—Ni-based sintered alloy or a Cu-based sintered alloy having the porosity shown in Tables 1 and 2, respectively, and both have an outer diameter of 9 mm X Diameter: 5 mm X Height: Bearing of the present invention having dimensions of 6 mm 1 ⁇ 15 and conventional bearings 1 to 3 were manufactured.
- the bearings of the present invention 1 to 15 showed that Also, the pores are dispersed and distributed at a rate of 8 to 18% in the matrix of the Cu—Ni alloy grains, and the P component is present in the grain boundaries of the Cu—Ni alloy grains, and in the pores.
- the conventional bearings 1 to 3 each had a structure in which free graphite was dispersed and distributed on a Cu alloy base material.
- FIG. 1 is a schematic view of a micrograph of the bearing 3 of the present invention taken by an optical microscope.
- Impeller rotation speed 500 000 (minimum rotation speed) to 150 000 (maximum rotation speed) r.pm
- gasoline flow rate 50 litre torque (minimum flow) to 250 litre torque ( (Maximum flow rate)
- Pressure received by the bearing from the high-speed rotating shaft Max. 50 O KPa
- Test time 500 hours, that is, gasoline flows through a narrow gap at a high speed, and the motor's high speed causes this.
- Tables 1 and 2 show the crushing strength of each bearing for the purpose of evaluating the strength.
- the bearings 1 to 15 of the present invention composed of a CU-Ni-based sintered alloy were all superior due to the Cu-Ni alloy grains constituting the base material.
- Abrasion resistance and corrosion resistance, high strength due to the effect of improving the sinterability of the P component distributed at the intergranular portion of the Cu-Ni alloy grains, and the effect of pores to form a fluid lubricating film and free graphite In combination with the effect of improving wear resistance by the action, especially when used as a bearing for a motor-type fuel pump, it exhibits more excellent wear resistance under high-pressure and high-speed gasoline circulation, whereas Cu-based Conventional bearings 1 to 3 made of sintered alloys have the same high strength, but wear progresses relatively quickly, and it is clear that the service life can be reached in a relatively short time.
- the bearing of the present invention can be used not only for a motor-type fuel pump for an engine using ordinary liquid fuel, but also for a motor-type fuel pump which is higher in height from a rotating shaft in accordance with miniaturization and higher driving.
