SWASH PLATE AND PRODUCTION METHOD OF THE SAME

摘要

A swash plate 3 includes a substrate 11 made of an iron-based material, a hard first resin layer 12 provided to coat an end surface of the substrate 11, and a soft second resin layer 13 provided to coat the first resin layer 12. A spiral annular groove 12A is formed in a surface of the first resin layer 12, and the second resin layer 13 is provided to match the sectional shape of the first resin layer 12. With the soft second resin layer 13 on a sliding surface 3A of the swash plate 3, a swash plate 3 having a good fit in an initial stage of sliding can be provided. When the second resin layer 13 partially wears, a protrusion 12 of the first resin layer 12 of the hard resin is exposed to provide good wear resistance and good sliding properties.

主权项

1. A method of producing a swash plate having a sliding surface that slides with respect to a shoe, comprising the steps of:
providing a substrate comprising an iron-, aluminum- or copper-based material; applying a resin paint for a first resin layer composed of hard resin to an end surface of the substrate to provide the first resin layer; drying and/or baking the first resin layer and then forming a minute annular groove in a surface of the first resin layer; applying a resin paint for a second resin layer composed of soft resin to the first resin layer provided with the annular groove; rotating the substrate at a high speed to remove unnecessary parts of the resin paint for the second resin layer; and forming the second resin layer to match a sectional shape of the surface of the first resin layer.
