Abstract
一种轴向振动减振器,可以隔离内、外元件之间的振动,上述内、外元件之间具有空间,其中设有片状弹簧和内部流体空间,以及使液压油在上述片状弹簧两侧面间流动,以便在上述内、外元件之间减振的液压油通路。
Description
本发明涉及使用片状弹簧的轴向振动减振器,用它作为支撑结构的支架,例如支撑大型引擎,建筑物的空调设备,印刷机械,桥梁,还有其它多种用途。本发明的轴向振动减振器具有高负载量,刚度和减振力易于控制,而且耐久性长。因此,本发明的振动减振器与常规的橡胶减振器相比,在长时期内能够更有效更经济地对轴向振动进行减振。
橡胶减振器非常便宜,并广泛用于弹性支架。但是,当将它用于高温环境,并经过长时间后,其弹性消失,由此,它的静力学和动力学特征产生变化。换句话说,其存在着耐久性问题。橡胶的刚度小于钢材,因此橡胶减振器不适于用来支撑高负载。近来,提出采用流体支架,即在橡胶减振器中设置填充油料的空间的修改方案增大减振力。而且,橡胶弹性支架且有非线性动力学特征,因此不容易控制这种支架的刚度和减振力。所以,很难设计出最佳的减振系统。
本发明的轴向减振器的目的是要克服上述橡胶型减振器的缺陷,其具有高负载量,很容易控制其刚度和减振力,并且其减振力高于橡胶型减振器。因此,这种减振器能够非常有效地减弱振动传递。而且,本发明的减振器不需要任何辅助部件或系统,因此可以大规模生产和实行标准化。由于这种减振器的尺寸小,所以很容易进行结构件和设备安装。而且,这种减振器能够用于高温环境。
在二次大战期间,由澳大利亚人,Geislinger博士发明的使用片状弹簧的振动减振器被用来控制扭转振动。 使用片状弹簧的扭振减振器被用于扭振阻尼器和内燃机引擎的联轴节。在此第一次发明以来,通过35年在世界范围内的广泛应用,这种减振器具有良好的性能,并且得到证实。
图1是本发明的内部截面的视图。
图2是本发明的侧剖面的视图。
图3是表示另一种类型的片状弹簧板垛的视图。
图1~3中用代号表示的部件如下所述:
1:片弹簧 4:油槽
2:外运动元件 5:密封元件
3:内固定元件 6:内部流体空间
如图1和2所示, 本发明的轴向振动减振器由若干片弹簧的板垛和内部流体空间组成。由片弹簧弹性支撑着外运动元件。所述片弹簧沿径向安装在内固定元件上。由片弹簧的数量、几何尺寸(即,厚度、宽度和长度)及材料,还有片弹簧板垛的数量决定支撑力。因为可以控制片弹簧板垛的弹性支撑力,安装在本发明的振动减振器上的机械的固有频率很容易得到控制。当固有频率得到控制时,使固有频率远离驱动频率就能大大加强机械的稳定性。
如图2所述,由片弹簧板垛1将内部流体空间6分为上、下空间。油通过槽4流动,所述槽4位于片弹簧板垛1的两侧。外运动元件2和内固定元件3之间的相对运动导致内部流体空间6的体积变化。当空间6的体积变化时,上、下空间出现压力差。此压力差迫使油流动,因此由槽4的不同尺寸和油粘度控制减振力。
理论分析结果表明,本发明减振器的减振力大于橡胶减振器,而且本发明减振器的动力学特征呈线性特性。因此, 很容易设计出最佳减振系统。
