Abstract

本实用新型公开了一种活塞顶结构,所述活塞顶上设有气环凹槽、螺柱孔和销孔。本实用新型的一种活塞顶结构,现在高强度、低温胀的材料已用于此结构形式活塞上,目前此类活塞结构从160-400mm缸径不等,此种活塞能够替代组合活塞,使成本更加的低廉,并且能够在烧重油、高爆压等恶劣的工况下,持续不断的工作。

Description

活塞顶结构
技术领域
本实用新型涉及一种活塞顶结构。
背景技术
现有技术中,活塞顶结构上的气环凹槽过于集中,间隙过大,致使活塞顶结构精度不够。
发明内容
本实用新型的目的是提供一种活塞顶结构。
本实用新型为实现上述目的所采用的技术方案是:一种活塞顶结构,所述活塞顶上设有气环凹槽、螺柱孔和销孔。
所述气环凹槽宽度为5-5.1mm。
所述螺柱孔的深度为19mm。
所述销孔的深度为7mm。
本实用新型的一种活塞顶结构,现在高强度、低温胀的材料已用于此结构形式活塞上,使成本更加的低廉,并且能够在烧重油、高爆压等恶劣的工况下,持续不断的工作。
附图说明
下面结合附图和具体实施方式对本实用新型作进一步说明。
图1是本实用新型一种活塞顶结构的结构示意图。
具体实施方式
如图1所示,本实用新型活塞顶结构,活塞顶上设有气环凹槽1、螺柱孔2和销孔3,气环凹槽宽度为5-5.1mm,螺柱孔的深度L2为19mm,销孔的深度L1为7mm,销孔3直径?为6mm,环槽外边缘倒角C0.2±0.1。

Claims (4)
