Abstract

一种组合密封环，包括一个第一密封元件和一个第二密封元件。第一密封元件比第二密封元件容易变形。密封件的并列表面被形成，以减少第一密封元件的挤压传递至第二密封元件。

Description

在美国专利证书3，848，880号中公开了型号的油压缸，通常采用一种组合密封环在活塞上，以防止液体漏泄流经活塞。正如上述专利所谈到的，用于这种油缸的单一包含的组合密封环，包括了一个相对硬些的合成橡胶的U型杯，和一个相对软些的合成橡胶的密封环，后者塞进U型杯的中心凹坑内。密封环可机械地保留或粘结在U型杯内。
本发明提供一经过改进的组合密封环，适用于低温条件下高压系统的密封。
组合密封环包括一个环形的第一密封元件和一个环形的第二密封元件。第一密封元件是由相对较易变形材料制造，并且机械地陷进保留在第二密封元件内。
第二密封元件是由相对坚固的材料例如硬的热塑性塑料制成的，它有倒锥形的面，其作用是对第一密封元件起着推挤压的支承。还有，第二密封元件含有第二密封唇缘，其作用好似装置上多余的密封，而且它随后当第一密封件移动时受力。
超越类似装置提供的优点是，不要求像现行密封环对第二密封元件施加压力，而产生优越的最初密封，并且在遇到液体高粘度和温度低时，在低压力使用时，有使油膜分开的作用。第二密封元件，当压力增大时，随后受到用力，因而在系统的受压力的整个范围内，对第一密封元件起着好似多余密封的作用。第一和第二密封件之间相互作用的结构，可阻止在第二密封元件和油缸壁之间的相对较软的第一密封元件的挤压。
图1本发明的组合密封环的立体图，部分已剖开;
图2组合密封环的剖视图，处于自由或未装配状态;
图3组合密封环的剖视图，处于已装配在油缸和活塞之间的状态;
依照本发明最理想的实例，一个组合密封环包括一个第一密封元件，接合于U型的第二密封元件，第一密封元件10是由相对较软的和可变形弹性体例如合成橡胶或合成弹性体，或者由热固性或热塑性塑料制造的。第一密封元件10，在肖氏硬度计A档刻度有60至90的硬度值。
第二密封元件12，通常是U型的横断面，是由相对坚固稍有可变性和可弯曲性的材料制造的，包括可弯曲的或相对坚固的弹性体，相对硬些的橡胶，或者热固性的或热塑性的塑料，例如聚胺脂或聚酰胺塑料，按肖氏硬度计A挡刻度有95至125的硬度值。在所有场合下，第二密封元件的材料是比第一密封元件的材料硬些和稍不易变形。
在图2和图3中看得最清楚，第二密封元件12有一个环状T型的凹坑14，其内用来接受悬挂的通常是T型的圆柱16，它在第一密封元件10上，将元件10和12机械地联锁。
依据本发明一性能，第二密封元件有一对方向相反的支臂18和20，在整个时间都分别地和油缸23的壁22和活塞26的壁24相啮合。相似地，第一密封元件10有一对环形唇缘28和30，其分别与油缸23的壁22和活塞26的壁24啮合。元件10有一凹槽32，位于唇缘28和30之间，当组合密封环8承受加压液体时，它增加元件10的横向弯曲。
依照本发明的另一性能。元件10配有会聚的斜面34和36，分别地从唇缘28和30轴向地和径向地延伸，以阻止唇缘28和30的挤压传递到元件12的支臂18和20。这种抗挤压性能由元件12支臂18和20上的斜端面38和40得到补充，端面38和40分别补充地支承在元件10上的斜面42和44，因而更进一步地阻止元件10的挤压传递到元件12上的支臂18和20。
如图3所示的装配状态中，元件10的位于唇缘28和30之间的中央凹坑，由如图2所显示的最初状态变形而来，使唇缘28和30容易弯曲，因此在油缸壁22和活塞壁24上保持一斜面，甚至虽然在油缸22无显著的液体压力时也如此。换句话说，元件12的唇缘18和20，以及元件10的唇缘28和30，装配时都变形，致使和油缸23的壁22和油塞26的壁24保持最初的密封接触。
本发明的理想实例公开的同时，可以看到本发明容许有其变型，并且不脱离下述权利要求的范围。

Claims (2)

1、一种组合密封环，用来安置在具有中心轴线的圆形元件，上述密封环的特征是其包括有：
一个环状第一密封元件，有肖氏硬度计A档刻度有60至90的硬度值；
一个环状第二密封元件，在肖氏硬度计A档刻度有95至125的硬度值；
上述第二元件通常是U型的径向剖切面，限定于由径向延伸的弯曲部分连结的径向间隔轴向延伸的支臂；
上述第二密封元件的支臂，通常是分别和上述圆形元件与支承元件的壁相啮合；
上述第二元件上的支臂，有轴向锥形端面，分别向着其弯曲部分轴向和径向地倾斜；
上述第一元件有一对径向间隔的唇缘，以轴向地和径向地的斜面，补充地和以并列关系至上述第二元件的端面，以阻止上述第一元件的挤压传递至上述第二元件的支臂上。
2、根据权利要求1的密封环，其特征是上述第一密封元件上的唇缘，径向地倾斜向着上述第二密封元件的弯曲部分，由此上述第一密封元件的斜面和上述第二密封件上锥形端面之间的接合面，比锥形端面的径向尺寸小。
