Abstract

本实用新型公开了一种拉毛珩磨活塞环,它包括与缸套接触的支撑面,所说支撑面表层上布满油穴,该油穴呈网状交错分布。本实用新型无机械加工痕迹,支撑面无尖峰,因此,它具有耐磨性高;磨合期短;耐热性高,同时减小了工作面磨耗;贮油性好;密封性好等特点。适用于高速、高负荷柴油机发动机。

Description

拉毛珩磨活塞环
(一)、技术领域:
本实用新型涉及一种活塞环,具体涉及拉毛珩磨活塞环。
(二)、背景技术:
现有活塞环表面镀铬、氮化及喷砂处理,有明显的加工痕迹,易出现拉缸等情况。普通珩磨虽表面光亮,但也有明显的加工痕迹。
(三)、发明内容:
本实用新型所要解决的技术问题是提供一种提高发动机的整体性能,不会出现拉缸等情况的拉毛珩磨活塞环。
为了解决上述技术问题,本实用新型的拉毛珩磨活塞环,包括与缸套接触的支撑面,所说支撑面表层上布满油穴,该油穴呈网状交错分布。
由于上述技术方案中的活塞环与缸套接触的支撑面经拉毛珩磨处理后,其表面呈暗灰色,无机械加工痕迹,SEM照片显示支撑面无尖峰,布满油穴,该油穴呈网状交错分布。因此,本实用新型具有耐磨性高;磨合期短;耐热性高,同时减小了工作面磨耗;贮油性好;密封性好等特点。适用于高速、高负荷柴油机发动机。
(四)、附图说明:
图1是本实用新型拉毛珩磨活塞环结构示意图;
图2是图1所示实施方式中支撑面表层SEM照片。
(五)、具体实施方式:
由图1、图2可见,本实用新型拉毛珩磨活塞环与缸套接触的支撑面表层1上布满油穴2,该油穴2呈网状交错分布。本实用新型拉毛珩磨活塞环的支撑面表层结构先经普通珩磨再经抛光珩磨而获得。

Claims (1)
