三片组合钢带油环应用:三组元钢带组合油环,由于它具有良好 的圆周密封和侧面密封性能而被广泛 应用于高真空内燃机中。说明:三组元钢带组合油环由一片复合撑簧 及两片刮片组成。刮片的侧面与撑簧 环轴向支撑肩接触,其内圆面与衬簧 的径向支撑凸台接触。组合环压入气 缸内壁以后,撑簧的经向支撑凸台与 刮片受压对缸壁产生径向密封作用; 由于凸台具有一定的斜度,刮片与环 槽的上下侧壁之间也将产生一个分 力,保持侧向密封。
Three-piece combination of steel ring oil ring application: Three sets of steel band combination of oil ring, because of its good circumferential seal and side sealing performance has been widely used in high-vacuum internal combustion engine. Description: Three sets of steel band combination oil ring consists of a composite support spring and two scraper. The side of the blade is in contact with the axial support shoulder of the stay ring and the inner circular surface of the blade is in contact with the radial support bosses of the spring. After the combination ring is pressed into the inner wall of the cylinder, the meridional support boss of the stay spring and the blade are pressed to exert a radial sealing effect on the cylinder wall. Since the boss has a certain slope, the scraping sheet and the upper and lower side walls of the ring groove There will also be a component of force to keep the seal sideways.
