Title
(EN) SWASH PLATE
(FR) PLATEAU OSCILLANT
(JA) 斜板
Abstract
(EN)
This swash plate (2) comprises a resin film layer (12) formed on the front surface (2A) and the back surface (2B), and said resin film layer acts as the sliding surface which slides on a shoe (4). The inner periphery (12A) of the resin film layer (12) is a slanted surface which a lubricant can easily cross over. In order words, angle θ1 is 10° or less and angle θ2 of the rising portion (12D) is set to 20° or less, and when the lubricant is supplied from the inner periphery side of the swash plate (2), said lubricant easily crosses over said inner periphery (12A) which is a slanted surface, and is quickly supplied to the surface (2A) (the sliding surface) outside of said inner periphery. Because the lubricant is quickly supplied to the front surface (2A) and the back surface (2B) (the sliding surface) of the swash plate (2), seizure of the swash plate (2) can be prevented.
(FR)
La présente invention concerne un plateau oscillant (2) qui comprend une couche (12) de film de résine formée sur la surface avant (2A) et la surface arrière (2B), ladite couche de film de résine servant de surface coulissante qui coulisse sur un patin (4). La périphérie interne (12A) de la couche (12) de film de résine est une surface inclinée qu'un lubrifiant peut aisément traverser. En d'autres termes, l'angle θ1 est inférieur ou égal à 10° et l'angle θ2 de la partie montante (12D) est défini pour être inférieur ou égal à 20°, et lorsque le lubrifiant est alimenté depuis le côté de périphérie interne du plateau oscillant (2), ledit lubrifiant traverse aisément ladite périphérie interne (12A) qui est une surface inclinée, et est rapidement alimenté vers la surface (2A) (la surface coulissante) à l'extérieur de ladite périphérie interne. Étant donné que le lubrifiant est rapidement alimenté vers la surface avant (2A) et la surface arrière (2B) (la surface coulissante) du plateau oscillant (2), le grippage du plateau oscillant (2) peut être évité.

 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、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。
