  • Patent Document 1 focuses on the size of Si particles and improves fatigue resistance and wear resistance.
  • the bearings often deformed due to misalignment of the assembly and insufficient rigidity of the housing due to weight reduction and compactness.
  • the frequency of contact with the shaft increases, and heat generation reduces the strength of the bearing material, resulting in cracks and the occurrence of oil film breakage, which may eventually lead to seizure.
  • the present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide an aluminum alloy bearing that has good seizure resistance by preventing oil film breakage by preventing generation of cracks due to a decrease in material strength. It is to provide.
  • the invention according to claim 1 is an aluminum alloy bearing containing 1.0 to 10.0% by weight of Si and in which Si particles are dispersed.
  • the diffraction intensity ratio is 0.6 or more.
  • the invention according to claim 2 is the aluminum alloy bearing according to claim 1, wherein the aluminum alloy bearing has a bearing surface and a bearing interior at a position deeper than the bearing surface in the thickness direction.
  • the ratio Dr between the diffraction intensity of the (111) plane of the Si particles and the diffraction intensity of the (111) plane of the Si particles inside the bearing is 0.8 ⁇ Dr ⁇ 1.2. .
  • the invention according to claim 3 is the aluminum alloy bearing according to claim 1 or 2, characterized in that it contains any one or more of the following (a) to (c).
  • a total amount of at least one selected from Mn, V, Mo, Cr, Co, Fe, Ni, and W is 0.01 to 3.0% by weight.
  • C A total amount of at least one selected from B, Ti and Zr is 0.01 to 2.0% by weight.
  • good seizure resistance can be obtained by setting the diffraction intensity ratio of the (111) plane of the Si particles whose crystal orientation is represented by the Miller index to be 0.6 or more.
  • the friction coefficient can be reduced if the crystal grain orientation of the Si particles is optimized, that is, if the diffraction intensity ratio of the (111) plane of the Si particles is high, and heat is generated due to friction caused by contact between the Si particles and the shaft. This is because the occurrence of cracks due to a decrease in strength can be prevented by reducing the thickness, and the seizure resistance can be improved by avoiding the oil film breakage.
  • Other peak intensities [(400) plane, (511) plane, (440) plane, etc.] are not included because the peak intensity is low and overlaps with the background and has a large error.
  • the Si particles have a cleavage plane on the (111) plane. Therefore, it is considered that when the rolling is performed, the Si (111) plane efficiently increases when stress is applied to the Si particles.
  • the hardness of the Si particles themselves is very hard, about 1000 HV, and the cleaved surface roughness is smoother than the surface roughness of the product to be completed thereafter, so the friction coefficient is low. Heat is reduced, cracking due to a decrease in material strength can be prevented, and oil film breakage can be avoided.
  • the ratio Dr between the diffraction intensity of the (111) plane of Si particles on the bearing surface and the diffraction intensity of the (111) plane of Si particles inside the bearing is 0.8 ⁇ Dr. ⁇ 1.2.
  • Aluminum alloy bearings are repeatedly deformed by continuous use. If the difference in internal stress between the bearing surface and the inside of the bearing is large, a large relative internal stress is generated between them, and strain energy is concentrated. If strain energy due to deformation is added to the aluminum alloy bearing and exceeds the limit that the aluminum alloy bearing can withstand, it causes cracks in the aluminum alloy bearing. On the other hand, by rolling the aluminum alloy bearing to a state where the amount of change in length in the direction perpendicular to the thickness direction is as small as possible, the difference in internal stress between the bearing surface and the inside of the bearing is reduced.
  • the aluminum alloy bearing is rolled to a state where the difference in the amount of change is small between the bearing surface and the inside of the bearing, thereby preventing the occurrence of cracks and improving the durability against seizure.
  • the position inside the bearing can be set at a substantially central position in the thickness direction of the aluminum alloy bearing.
  • the ratio Dr of the diffraction intensity is 0.8 ⁇ Dr ⁇ 1.2, the difference in variation is reduced, and the difference in internal stress between the bearing surface and the bearing becomes small. . Therefore, by defining the ratio Dr of the diffraction intensity, durability against seizure, that is, seizure resistance can be improved.
  • Aluminum alloy bearings can be formed by laminating steel backing metal and, in some cases, other members in order to exhibit high bearing performance. In the case where the aluminum alloy bearing is made of such a composite material, the following manufacturing method is particularly effective.
  • diffraction intensity ratio Dr for example, different peripheral speed rolls having different speeds between the upper roll and the lower roll of the rolling roll can be used. Moreover, you may roll by controlling a friction coefficient by adjusting the roughness of the surface of the member used as an aluminum alloy bearing, or a roll. Thus, by using the different peripheral speed rolls or adjusting the surface roughness, the amount of change can be controlled to control the internal stress applied to the aluminum alloy bearing. Therefore, not only can the stress be applied appropriately to the Si particles by such rolling, but also the difference in internal stress between the bearing surface of the aluminum alloy bearing and the inside of the bearing can be reduced.
  • the strength and heat resistance of the Al matrix can be improved.
  • the aluminum alloy bearing 1 was manufactured by the procedure described below. First, the crystal grain size of the Al billet of the initial billet was manufactured to 30-50 ⁇ m by a continuous casting machine. Thereafter, rolling was repeated until a predetermined thickness was obtained, and the crystal grains were extinguished at least once in a rolling process in which the elongation ratio was 2 to 8 times to obtain an aluminum bearing alloy plate. Further, in the rolling process, the upper roll and the lower roll of the rolling roll are rolled at different speeds, for example, the lower roll is increased by 2% of the upper roll, and / or the material surface is roughened to increase the friction coefficient. By rolling, the aluminum bearing alloy plate was given more internal stress while reducing the difference in internal stress between the vicinity of the surface and the internal predetermined position. As a result, it was possible to give more internal strain to the aluminum bearing alloy plate and to eliminate the crystal grains more efficiently. In addition, you may perform the annealing process of distortion removal for crack suppression in the middle of a rolling process.
  • a bimetal is manufactured by pressing the aluminum bearing alloy plate rolled to a predetermined thickness as described above against a steel back metal. At this time, an aluminum plate serving as an adhesive layer may be interposed between the aluminum bearing alloy plate and the steel back metal and pressed. Then, after the pressure welding, an annealing treatment for increasing the adhesive force and strain removal may be performed, and a heat treatment such as a solution treatment for strengthening the aluminum bearing alloy plate may be performed as necessary. Further, the bimetal may be rolled. The bimetal produced as described above was processed into a semi-cylindrical shape to obtain a half bearing.
  • the peak intensity of Si particles was measured by X-ray diffraction using the manufactured half bearing. And the abrasion test was done on the test condition shown in FIG. 1 of the half bearing measured in this way, and the seizure test was done on the test condition shown in FIG.
  • the wear test the amount of wear ( ⁇ m) is measured by positively contacting the shaft by starting and stopping, and the wear resistance is evaluated.
  • the seizure test a load is applied to the inner surface of the bearing, and the maximum surface pressure (MPa) that does not seize in a predetermined test time is evaluated as seizure resistance.

From the comparison between Example Product 7 and Comparative Product 1, if the diffraction intensity ratio of the (111) plane of the Si particles is 0.6 or more in consideration of errors, both wear resistance and seizure resistance are obtained.
