Description

弹性联轴节和用于弹性联轴节的弹性体元件
技术领域
本发明涉及一种具有权利要求1前序部分特征的可插接的弹性联轴节以及一种按权利要求4的弹性体元件。
背景技术
这种可插接的联轴节广泛应用于工业和不同的用途中,如泵的传动。这些联轴节在发生轴偏移(不对心)的同时传递要连接的机器的扭矩。在有些应用中优选无防冲击装置的弹性联轴节(“冲击式结构类型”),它们的特征在于,当弹性体元件过载或磨损亦即破坏时,保证联轴节各部分相互不接触地自由旋转。
例如按DE 3910502C2具有弹性体元件的弹性联轴节通过周向力传递扭矩,周向力最初在弹性体元件上作用弯和压负荷。为了在规定的结构尺寸下传递尽可能大的扭矩,应将弹性体元件设计得尽可能硬。另一方面要连接的机器的轴的偏移会导致弹性体元件变形。对于小的复位力并因而对于要连接的机器小的附加轴承力的要求同样期望尽可能软的弹性体元件。此外,弹性体元件的硬度关键性地决定了联轴节的扭转弹性。在这方面往往也要求具有相应的高缓冲的软性设计。
目前采用具有基本上性质均匀的弹性联轴节的弹性体元件,其中往往不能充分覆盖上面说明的矛盾的要求。要么弹性体元件设计得比较硬,缺点是只允许有小量的轴的偏移,要么采用比较软的弹性体元件,从而必须限制在规定的结构尺寸下能传递的扭矩。
发明内容
本发明的目的是设计按此类型无防冲击的弹性联轴节的弹性体元件,使之不仅能满足传递大扭矩的要求,而且满足复位力小和能补偿轴偏移的要求。
在按此类型无防冲击装置的弹性联轴节中,按本发明此目的通过权利要求1特征部分所述特征达到。本发明有利的设计是从属权利要求2和3的内容,以及从属权利要求5至9针对弹性体元件。
按本发明的无防冲击装置的弹性联轴节的弹性体元件采取下列措施满足所提出的互相矛盾的目标要求,即,组成弹性体元件的两个区域的每一个分别按要求之一设计。其中,弹性体元件第一个最初通过周向力受弯曲负荷的区域设计得比较硬,而第二个最初受压应力的应承受比较大的变形部分的区域设计得比较软。迄今采用的弹性体元件的外部尺寸可以保持不变,所以按本发明的弹性体元件可以在不改变弹性联轴节连接构件的情况下使用。
附图说明
附图表示本发明的实施例并在下面进一步说明。其中:
图1通过弹性联轴节的纵剖面;以及
图2按图1的弹性联轴节中一个弹性体元件的放大纵剖面。
具体实施方式
图示的无防冲击装置的可插接弹性联轴节由一个第一半截联轴节1和一个第二半截联轴节2组成,它们装在要连接的机器的轴上。在第一半截联轴节1中在一圆弧上制有多个彼此有间距的窝3。在每个窝3内装入一个弹性体元件4,此弹性体元件4沿径向向内和沿径向向外定向的端部8压入第一半截联轴节1内。第二半截联轴节2设有凸块5,它们分别插入第一个半截联轴节中弹性体元件4之间的空隙内。通过凸块5,实现以一个作用在弹性体元件4沿径向在内部和沿径向在外部的端部8上的周向力形式的扭矩传递。如果弹性体元件4破坏,这两个半截联轴节1、2可不直接接触地自由旋转。
图2放大表示的弹性体元件4有一个第一区域6和一个第二区域7。第一区域6基本上沿联轴节径向延伸并有渐成锥形的端部8,弹性体元件4通过端部8压紧在第一半截联轴节1内。第二区域7有两个隆凸的形式,在联轴节压合的情况下,隆凸在凸块5所在高度侧向成形在弹性体元件4的第一区域6上。在隆凸的内侧制有倒截的型面9,隆凸借助型面9按一种嵌接的方式啮合在第一区域6内。弹性体元件4的这两个区域6、7通过硫化互相牢固连接。除通过硫化材料封闭地连接外,通过倒截型面9的嵌接构成形封闭的连接。
弹性体元件4的两个区域6、7设计成不同的性质。第一区域6与第二区域7相比设计成形状更稳定和较硬,并受压和弯的组合负荷。由两个隆凸组成的第二区域7与第一区域6相比设计成较软和更富弹性。此第二区域7最初受压应力,并基于从外部给定的变形的特殊设计可没有较大复位力地下沉。此外有利的是,基于与一种硬的橡胶元件相比有较大的摩擦系数,避免了在凸块5与弹性体元件4第二区域7的隆凸之间在较软的表面上的相对运动。由此抑制了在弹性体元件4上的磨损。
