Definitions
- the present invention relates to a sliding surface of a sliding member such as a hemispherical shoe, for example, and relates to a sliding surface of the sliding member having improved seizure resistance by improving the sliding surface.
- a hemispherical shear used for a swash plate compressor is known as a sliding member used under severe conditions.
- This hemispherical shroud has a hemispherical hemispherical surface and a smooth end surface, the hemispherical surface is in sliding contact with the hemispherical concave portion of the piston constituting the swash plate compressor, and the end surface is provided on the rotating shaft. It comes in sliding contact with the swash plate. That is, in the hemispherical shoe, the hemispherical surface is a sliding surface with respect to the piston, and the end surface is a sliding surface with respect to the swash plate.
- the sliding contact surface of the hemispherical shoe is usually manufactured smoothly with a roughness less than a required value (Patent Document 1).
- Patent Document 1 Japanese Patent Laid-Open No. 2001-153039
- the present invention has further improved the seizure resistance of the sliding surface of a sliding member such as a hemispherical shoe, which requires high seizure resistance, as compared with the conventional one.
- a sliding surface of the sliding member is provided.
- the sliding surface of the sliding member is directly hardened linearly or in a dot shape to form a convex portion, and a concave portion is formed in a non-directly hardened portion adjacent to the directly hardened portion.
- the present invention provides a sliding surface of a sliding member characterized in that an uneven surface is formed on the sliding surface between the direct quenching portion and the non-direct quenching portion.
- a hemispherical shroud 1 as a sliding member is used in a conventionally known swash plate type compressor, which is not shown but is inclined to a rotating shaft.
- the piston is reciprocally driven with the rotation of the swash plate, and is interposed between the swash plate provided on the piston and the hemispherical recess provided on the piston.
- the hemispherical shroud 1 includes a hemispherical hemispherical surface 2 and a smooth end surface 3.
- the hemispherical surface 2 is in sliding contact with the hemispherical concave portion of the piston, and the end surface 3 is in sliding contact with the swash plate. It has become.
- an oil sump 4 including a concave portion is formed at the center of the end surface 3.
- convex portions 3a are formed in a lattice shape on the end surface 3, and the portions other than the convex portions 3a are relatively concave portions 3b, so that the end surface 3 An uneven surface is formed.
- the convex portion 3a is formed by irradiating the end surface 3 with a laser and directly quenching the end surface 3 by the irradiation. That is, as shown in FIG. 3, the irradiated portion irradiated with the laser is in a state where the base material surface 3c that originally formed the surface of the end face 3 is directly quenched. It bulges out from the surface, so that the convex part 3a is formed.
- the indirect quenching portion is recessed relative to the convex portion 3a to form a concave portion 3b.
- the recess 3b which is a non-hardened part, is not hardened.
- the quenching range by laser irradiation is semicircular in cross section with the laser irradiation position as the center, as shown by the imaginary line 5 in FIG. 3, for example. Even in the recess 3b of the non-directly quenched portion, it can be quenched. Whether or not to quench the recess 3b, which is the indirect quenching portion, can be set by the laser irradiation interval. Then, if the recess 3b, which is an indirect quenching portion, is quenched, the portion bulges out from the base material surface 3c, if not as much as the projection 3a.
- YAG laser was irradiated on the end face 3 of the hemispherical shoe 1 manufactured by SUJ2 in a straight line and at a parallel interval of 0.2 mm, and parallel to the direction perpendicular to this also at a 0.2 mm interval.
- This interval is preferably in the range of 0.1 to 0.3 mm.
- the output of the YAG laser is 50 W, and the condenser lens is adjusted so that the YAG laser is focused at a position 2 mm deep with respect to the surface of the end surface 3. In some cases, YAG laser was irradiated in a defocused state.
- the surface of the convex portion 3a which is a directly quenched portion irradiated with the laser, has a hardness increased by about HvlOO with respect to Hv750, which is the hardness of the base material, and the surface of the concave portion 3b increased by about Hv50. It was.
- the portion 6 (see Fig. 3) that is slightly deeper than the directly quenched portion is annealed and has a hardness that is about HvlOO lower than that of the base metal, and the directly quenched portions are convex portions 3a and 3a.
- the crossing point that is, the part where the laser irradiated part intersects, was also annealed, and the hardness was still about HvlOO lower than the base metal. However, since quenching by laser is rapid cooling, the hardness of the base metal was not recognized at a deeper position than the slightly deeper portion 6.
- the end surface 3 of the hemispherical shroud 1 is completed by sequentially performing lapping and puffing after laser irradiation as described above.
- the height of the convex portion 3a relative to the concave portion 3b is determined by laser processing. Immediately after it is 0.1 to about LO / zm, it is desirable that the finished product after lapping and puffing should be in the range of 0.1 to 1 ⁇ m.
- the rotational speed of the swash plate is increased under the above conditions with the end face of the product of the present invention pressed against the swash plate.
- the surface pressure when the product of the present invention was pressed against the swash plate was increased under the above conditions, and it was determined that seizure occurred when the axial torque applied to the swash plate exceeded 4. ON ⁇ ⁇ .
- the product of the present invention has much better seizure resistance than the comparative product.
- FIG. 5 to FIG. 8 show other embodiments of the present invention, respectively.
- FIG. 5 shows that the direct quenching portion is formed in a parallel straight line to form the convex portion 3a, and the direct quenching portion.
- a concave portion 3b is formed in a non-directly quenched portion adjacent to the surface, and an uneven surface is formed on the sliding surface between the directly quenched portion and the non-directly quenched portion.
- FIG. 6 shows a concentric convex portion 3a
- FIG. 7 shows a spiral convex portion 3a
- FIG. 8 shows a case where a laser beam is radiated to the lattice-like intersections, and the convex portions 3a are formed on the sliding surface in the form of dots.
- the force using the hemispherical shoe 1 as the sliding member is not limited to this, and the present invention can of course be applied to various sliding surfaces.
- a force for forming a convex portion by directly quenching the sliding surface with a laser can use a plasma beam or the like that is not limited to this.
- FIG. 1 is a front view showing a first embodiment of the present invention.
- FIG. 2 is a bottom view of FIG.
- FIG. 3 is an enlarged cross-sectional view showing an essential part of FIG. 2 in an exaggerated manner.
- FIG. 5 is a bottom view showing a second embodiment of the present invention.
