随着各种机械装置的高速化、小型化,对机械密封又提出了新的要求。现有的机械密封型式,结构仍然比较复杂,加工工艺性差,生产成本高;其弹性元件采用圆柱或圆锥螺旋压缩弹簧,轴向占据空间位置太长,因而影响了机械密封应用范围的进一步扩大。下面介绍我们用波形片作弹性元件的新型机械密封的应用实例,以及对波形弹簧设计计算所作的力学分析。 With the high speed and miniaturization of various mechanical devices, new demands are placed on mechanical seals. The existing mechanical seal type and structure are still relatively complicated, the machining technology is poor, and the production cost is high. The elastic element adopts a cylindrical or conical helical compression spring, and the occupied space in the axial direction is too long, thereby affecting the further expansion of the application range of the mechanical seal. Here is an example of the application of a new type of mechanical seal with a wave-shaped spring element and a mechanical analysis of the wave spring design and calculation.
