Abstract

本实用新型公开子一种容易加工且使用寿命长的分瓣式活塞环,它包括瓣体,将瓣体的外搭接面BC与瓣体的弦AB的夹角设计为大于或等于85度,本实用新型具有结构简单、加工方便、气体泄漏少、使用寿命长等特点。

Description

一种活塞环
技术领域:
本实用新型涉及一种活塞环,具体地说是一种分瓣式活塞环。
背景技术:
分瓣式活塞环一般都与弹力环一同使用,目前正在使用的分瓣式活塞环最常见的是三瓣式搭口环,其在加工时加工难度大,原材料消耗多;在使用时,存在泄漏通道,且随着环的磨损逐渐加大。
发明内容:
本实用新型的目的是提供一种容易加工且使用寿命长的分瓣式活塞环。
本实用新型是采用如下技术方案实现其发明目的的,一种活塞环,它包括瓣体,瓣体的外搭接面BC与瓣体的弦AB的夹角为大于或等于85度。
由于采用上述技术方案,本实用新型较好的实现了发明目的,具有结构简单、加工方便、气体泄漏少、使用寿命长等特点。
附图说明:
图1是本实用新型的形状结构示意图;
图2是图1的俯视图;
图3是本实用新型为三瓣时的示意图;
图4是本实用新型为四瓣时的示意图。
具体实施方式:
下面结合附图对本实用新型作进一步说明。
实施例1:
如图1、图2、图3所示,本实用新型将活塞环分为三瓣,它包括瓣体,其瓣体的外搭接面BC与瓣体的弦AB的夹角设计为大于或等于85度(本实施例为90度)。当角度过大时,尖角易断;过小时,则不能有效补偿。
本实用新型在使用过程中,虽然有磨损,但磨损后的圆弧
Figure Y0322682900041
仍将保持与 等长,BC面也将一直保持紧贴在另一瓣的AD面上。
实施例2:
如图4所示,本实用新型将活塞环分为四瓣,余同实施例1。
