Abstract

本发明的能密封汽缸的活塞环,就是在制作活塞环时,把活塞环加长1-1.4厘米。即每端加长了0.5-0.7厘米,在活塞环的两端的加长的部分上,分别加工成一正一反的台阶状,台阶的长度为0.5-0.7厘米。台阶的厚度为活塞环应有厚度的一半,要求活塞环放入汽缸后,活塞环正反台阶刚好合上,成为一个活塞环的厚度,各自的开口间隙通过加工一定要保持1-2毫米。由于活塞环的上下台阶互相封闭,而无直通的开口间隙,从而达到不漏气的目的。

Description

能密封汽缸的活塞环
技术领域:这是内燃机上的活塞环,尤其是一种能密封汽缸的活塞环。
背景技术;传统的活塞环,均有开口间隙,当压缩空气时,压缩空气或油气混合气会从活塞环的开口间隙处跑掉,影响内燃机的动力性能和增加耗油量。有人设计了双活塞环,就是在一个较大的活塞环槽内安上两个互相错开的活塞环,解决活塞环开口漏气问题,虽然解决了漏气问题,但要增加生产成本,增加加工工时和多费原材料。
发明内容:本发明的能密封汽缸的活塞环,就是在制作活塞环时,把活塞环加长1-1.4厘米。即每端加长了0.5-0.7厘米,在活塞环的两端的加长的部分上,分别加工成一正一反的台阶状,台阶的长度为0.5-0.7厘米。台阶的厚度为活塞环应有厚度的一半,要求活塞环放入汽缸后,活塞环正反台阶刚好合上,成为一个活塞环的厚度,各自的开口间隙通过加工一定要保持1-2毫米。由于活塞环的上下台阶互相封闭,而无直通的开口间隙,从而达到不漏气的目的。
具体实施方法:在制作活塞环时,把活塞环加长1-1.4厘米,在活塞环的两端各占加长的部分,加工成一正一反的台阶状。台阶的厚度为活塞环应有厚度的一半,要求活塞环放入汽缸后,活塞环正反台阶刚好合上,成为一个活塞环的厚度,各自的开口间隙通过加工一定要保持1-2毫米,由于活塞环的上下台阶互相封闭,而无直通的开口间隙,从而达到不漏气的目的。
附图说明:
图1为能密封汽缸的活塞环的活塞前视图,图2为活塞环两端台阶的互相闭合时的放大图;
图中1为活塞环一端的正台阶,图中2为活塞环另一端的反台阶,图中3为活塞环的不直通的开口间隙。
