Abstract

本实用新型属于改进的内燃机的活塞。特征是 这种活塞的活塞环是无开口环,由活塞筒、活塞顶盖, 活塞环槽用固定螺钉组合成整体。这种活塞的活塞 环与汽缸进行无隙配合,提高装配精度,解决了缩小 内燃机活塞与汽缸的配合间隙问题,带来增强动力、 延长寿命、节省燃料、减少烟尘等一系列优越性。

Description

本实用新型属于改进的内燃机的活塞。
常用的内燃机活塞是将活塞筒、活塞顶盖制成一个整体,而活塞环是开口环,活塞与内燃机的气缸配合总是有一定开口间隙,并且活塞环与气缸之间的配合形状为椭圆形。如何缩小内燃机活塞与气缸的配合间隙。这是活塞设计制造上有待解决的问题。
针对上述问题,本实用新型的目的是提供一种活塞环是无开口的新型内燃机活塞。这种活塞的活塞环与气缸进行无隙配合,提高装配精度。
这种内燃机活塞具有活塞筒1,在活塞筒1上部有活塞顶盖3和活塞环,特征是活塞筒1和活塞顶盖3之间有活塞环槽2,是用固定螺钉4将活塞筒1、活塞环槽2和活塞顶盖3组合成整体,并且活塞环槽2上的凹槽5上装有活塞环,该活塞环是无开口的活塞环。
本实用新型由于装配的是无开口活塞环,因而活塞环与气缸配合精度高,是无隙的圆形状配合。能增强动力,延长使用寿命;节省燃料,机油不上冒;能减少烟尘,减小振动,改善启动性能,取消走合期,根除敲缸,消除噪音;不仅适于内燃机,还适于空压机和氢、氧、氮压缩机。
图1、图2是本实用新型结构示意图,其中图1是主视图,图2是俯视图。
图3是活塞筒1结构示意图;
图4、图5是活塞环槽2结构示意图,其中图4是主视图,图5是俯视图。
本实用新型关键在于活塞环是无开口形状的,采取组合装配结构,或无开口活塞环和开口活塞环的混合同槽装配,效果最好。这样在运动中缩小了内燃机活塞与气缸的配合间隙,由于是无隙配合,使用后各种技术指标明显优于常用活塞。
