ZLM50B型轮式装载机转向液压缸的旧式缸盖(见图1)主要有以下缺陷:一是不便于油封4和导向套3的安装。由于安装孔的内径(45mm)小于油封的外径(60mm)和导向套的外径(50mm),安装油封和导向套时,需要用热水把油封和导向套加热软化后折叠,让其通过安装孔,有时甚至需要把导向套锯开才能安装,使用寿命大受影响。二是定位环5易破裂。由于定位环5的厚度仅3mm,使用过程中
ZLM50B wheel loader steering cylinder hydraulic cylinder head (see Figure 1) has the following major drawbacks: First, it is not easy to install the oil seal 4 and the guide sleeve 3. Because the inner diameter of the mounting hole (45mm) is less than the outer diameter (60mm) of the oil seal and the outer diameter of the guide sleeve (50mm), when installing the oil seal and the guide sleeve, the oil seal and the guide sleeve need to be softened and folded with hot water to let it pass Mounting holes, and sometimes even need to guide the sawing saw to be installed, the service life greatly affected. Second, the positioning ring 5 is easy to break. As the thickness of the positioning ring 5 is only 3mm, during use
