(EN) SWASH PLATE
(FR) PLATEAU OSCILLANT
Abstract
(EN)
This swash plate (2) comprises a resin film layer (12) formed on the front surface (2A) and the rear surface (2B), and said resin film layer serves as the sliding surface which slides on a shoe (4). The inner periphery (12A) of the resin film layer (12) is a tilted surface which a lubricant can easily cross over. In other words, angle ¸1 is 10° or less and angle ¸2 of the rising part (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 tilted 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 rear 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.
