Description

可换钢套摇摆
技术领域
本发明涉及一种摇摆结构,具体涉及一种钢套可换式摇摆结构。
背景技术
在现有技术中,变量柱塞泵和马达,多采用活塞拔销球头插入活塞孔中拨动摇摆来完成变量,因此球形活塞与摇摆活塞孔是线接触,摇摆活塞孔磨损很快,且磨损后无法维修,只能更换新的,维护成本高。
发明内容
发明目的:本发明的目的是为了克服现有技术中的不足,提供一种结构简单,维护成本低的可换钢套摇摆。
技术方案:为了解决上述技术问题,本发明所述的可换钢套摇摆,它包括摇摆体和摇摆臂,在所述摇摆臂上设有摆向定位孔,在所述摆向定位孔内设有可换式钢套,所述可换式钢套的内径和其一侧的摆向定位孔内径相同,所述可换式钢套的壁厚在2.5-3mm之间,所述可换式钢套的高度与摆向定位孔的高度比为(3/5-7/10):1。
所述摇摆体和摇摆臂为一体式结构。
所述可换式钢套的高度与摆向定位孔的高度比为2/3:1。
有益效果:本发明与现有技术相比,其显著优点是:本发明结构设置合理,在摇摆活塞孔处设置一个可换式钢套,钢套可经过淬火处理来增加它的耐磨度和硬度,将加工好的钢套压入摇摆壁的摆向定位孔内即可,本结构简单实用,维护时只要换掉钢套即可,大大降低了维护成本,采用2.5-3mm壁厚的可换式钢套和高度比为(3/5-7/10):1的可换式钢套与摆向定位孔,使其压入到位,完全能满足使用要求。
附图说明
图1是本发明的结构示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步的说明。
如图1所示,本发明所述的可换钢套摇摆,它包括摇摆体1和摇摆臂2,在所述摇摆臂2上设有摆向定位孔3,在所述摆向定位孔3内设有可换式钢套4,所述可换式钢套4的内径和其一侧的摆向定位孔3内径相同,所述可换式钢套4的壁厚在2.5-3mm之间,所述可换式钢套4的高度与摆向定位孔3的高度比为(3/5-7/10):1;所述摇摆体1和摇摆臂2为一体式结构。本发明结构设置合理,在摇摆活塞孔处设置一个可换式钢套,钢套可经过淬火处理来增加它的耐磨度和硬度,将加工好的钢套压入摇摆壁的摆向定位孔内即可,本结构简单实用,维护时只要换掉钢套即可,大大降低了维护成本,采用2.5-3mm壁厚的可换式钢套和高度比为(3/5-7/10):1的可换式钢套与摆向定位孔,使其压入到位,完全能满足使用要求。
本发明提供了一种思路及方法,具体实现该技术方案的方法和途径很多,以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围,本实施例中未明确的各组成部分均可用现有技术加以实现。
