Description

一种齿轮泵的泵盖
技术领域
本实用新型涉及一种齿轮泵的泵盖,属于液压传动技术领域。 
背景技术
齿轮泵泵盖是齿轮泵的一个关键部件,目前的齿轮泵泵盖是由一个泵盖及一个止口盘组成,二者作为两个分体单独加工,骨架油封安装在止口盘中,止口盘的内孔与外形同心度要求较高,以保证密封,止口盘与泵盖之间需要加装O型密封圈,止口盘、泵盖与O型圈配合面要求较高的光洁度,以保证密封,止口盘与泵盖之间采用螺钉联接。由于需与发动机输出轴连接,要求较高的同心度,加工工艺复杂,效率低,废品率高,要浪费大量的贵重金属。
实用新型内容
本实用新型的目的在于提供一种直接在泵盖上加工止口盘,结构简单,易于生产加工,能显著提高泵盖配合精度的齿轮泵泵盖。
本实用新型是这样实现的:该齿轮泵泵盖上设有止口盘,泵盖与止口盘为一体,在泵盖内的轴伸处设有骨架油封安装孔及卡簧槽。
本装置在泵盖上集成了一个止口盘,将传统的齿轮泵的泵盖和止口盘合二为一,作为一个整体加工、使用,能一次装夹同时完成止口盘、骨架油封安装孔、卡簧槽的加工。 
本实用新型的优点在于:1、简化加工工艺,节省贵重金属,减少了毛坯重量,节约能耗,生产效率高,易于大批量生产。2、加工及安装精度高,密封好,使用寿命长,容易维护。3、大大降低了废品率,降低成本。 
附图说明
以下结合附图对本实用新型做进一步说明。 
附图为本实用新型的结构示意图。 
具体实施方式
附图中,泵盖1上设有止口盘2,泵盖的轴伸处设有骨架油封安装孔3、 卡簧槽4。本实用新型具有传统的泵盖和止口盘的所有功能。 
本装置在泵盖上集成了一个止口盘,将传统的齿轮泵的泵盖和止口盘合二为一,作为一个整体加工、使用,能一次装夹同时完成止口盘、骨架油封安装孔、卡簧槽的加工。
