挡圈的类型:定义、用途、优点和缺点:

挡圈,也被广泛认为是弹性挡圈或卡环,是由金属制成的紧固件,安装在轴上或孔中的凹槽中或外壳以保留组件。这些装置采用轻巧、紧凑的设计将零件固定在适当的位置,与其他紧固技术相比,这种设计不需要大量的加工操作。 ( 紧固件种类 )

工程师通常根据其应用来区分挡圈:

  • 安装和拆卸要求

  • 环上的预期力载荷

  • 条件和操作环境

  • 成本

  • 转速

固定环的尺寸可以从直径 1mm 到 1m 不等。形状、样式、尺寸和材料的各种组合甚至可能导致设计在各种应用和行业中高效运行。以一辆标准汽车为例,在由转向、安全设备、动力总成等组成的系统中,可以有多达 50 个挡圈。

固定环还可以用于其他一些用途,例如风力涡轮机、健身器材、轴承固定装置、门把手、自行车、加油站、办公家具等等。

使用挡圈的主要原因是提供一个底座或简单地提供一个肩部,以阻止组件或子组件从外壳孔或轴上脱落。
