Abstract

本实用新型的技术内容是这样实现的,一种内燃机活塞,包括活塞销孔,耐磨铜套过盈装配在活塞销孔内;由于本实用新型活塞销孔内装配有耐磨铜套,当活塞在缸体中运行时,活塞销不再与活塞本体直接接触,而是与耐磨铜套接触,大大增加了活塞销孔与活塞销的耐磨程度,从而极大地改善了发动机的性能,提高发动机的使用寿命。

Description

一种内燃机活塞
技术领域
本实用新型涉及一种内燃机部件,特别涉及一种内燃机活塞。
背景技术
发动机活塞是车床加工而成表面没有经过特殊处理,在发动机高转速的高温状态下活塞销直接与活塞接触,活塞销孔与活塞销的磨损大,易造成活塞开裂、腐蚀,降低发动机性能及寿命,甚至造成拉缸。
发明内容
本实用新型为了解决上述现有产品存在的不足,提出一种内燃机活塞,具有使用安全、坚固耐用、生产简易的特点。
本实用新型的技术内容是这样实现的,一种内燃机活塞,包括活塞销孔,耐磨铜套过盈装配在活塞销孔内。
由于本实用新型活塞销孔内装配有耐磨铜套,当活塞在缸体中运行时,活塞销不再与活塞本体直接接触,而是与耐磨铜套接触,大大增加了活塞销孔与活塞销的耐磨程度,从而极大地改善了发动机的性能,提高发动机的使用寿命。
附图说明
图1:本实用新型的结构示意图。
具体实施方式
下面结合附图对本实用新型的结构原理和工作原理做详细说明。
参照图1,本实用新型的技术内容是这样实现的:一种内燃机活塞1,包括活塞销孔2,耐磨铜套3过盈装配在活塞销孔2内。
活塞销孔内装配有耐磨铜套,当活塞在缸体中运行时,活塞销与耐磨铜套接触,大大增加了活塞销孔与活塞销的耐磨程度。
