  • Patent number: 9021901
    Abstract: A hemispherical shoe 4 is equipped with a sliding surface 4A which slides with a swash plate 3, and a hemispherical convex 4B. Hardening is performed by radiating a laser so that minute circles 6 may be drawn on the sliding surface 4A. Then, lapping is given to the sliding surface 4A and, finally, buffing is given thereto. Thereby, the annular swelling portions 7? and concavities 8? are formed in positions of the circles 6 and, further, lubricating oil passages 10? which include net-like concavities are formed in the sliding surface 4A. A hardening part is formed of the above-mentioned annular swelling portions 7?. The above-mentioned annular swelling portions 7? are formed so that a ratio of an area of a total of all the above-described annular swelling portions 7? occupying an area of the sliding surface 4A which is a hardening object domain may become 0.3 to 0.8. It is possible to provide a shoe 4 which is good in seizure resistance in comparison with the past.
