Title
(EN) SWASH PLATE

Abstract
(EN)

PROBLEM TO BE SOLVED: To excellently prevent seizure of a swash plate 2 since lubrication oil easily gets over an inner peripheral part 12A being a slope to be quickly supplied to a surface 2A (sliding face) which is outward of it so that the lubrication oil is quickly supplied on the surface 2A of the swash plate 2, and a backside 2B (sliding face) when the lubrication oil is supplied from a side of the inner peripheral part of the swash plate 2.

SOLUTION: A swash plate 2 forms a resin overlay 12 on a surface 2A and a backside 2B, and is a sliding face slid on a shoe 4 there. The inner peripheral part 12A on the resin overlay 12 is a slope on which the lubrication oil easily gets over. In other words, an angle θ1 is 10 degrees or less, and an angle θ2 of a rise part 12D is set at 20 degrees or less.

【解決手段】 斜板2は、その表面2A,裏面2Bに樹脂被膜層12が形成されており、そこがシュー4と摺動する摺動面となる。樹脂被膜層12における内周部12Aは、潤滑油が乗り越えやすい傾斜面となっている。つまり、角度θ1は10°以下であって、立上り部12Dの角度θ2は20°以下に設定されている。
【効果】 斜板2の内周部側から潤滑油が供給されると、該潤滑油は傾斜面となっている上記内周部12Aを容易に乗り越えて、その外方となる表面2A(摺動面)に速やかに供給される。斜板2の表面2A、裏面2B(摺動面)に潤滑油が速やかに供給されるので、斜板2の焼付きを良好に防止することができる。
