本文论及的自主式机械面密封件已在НИИСУ(俄罗斯航空标准化统一化研究所 )进行了设计和试验 ,并指定用于航空技术产品。在已往所开展工作的基础上 ,系列标准ОСТ1 1 3792 -80～ОСТ1 1 380 1 -80开始在航空行业内实施。这些标准包含了机械面密封结构及其零组件的典型结构和尺寸。本文还给出了机械面密封结构的计算方法 ,示出了压力和作用力型谱 ,因而人们可以了解作用在上述密封结构的零组件 ,如碳圈、波形弹簧、橡胶圈上的力。本文给出的数学公式可用于计算波形弹簧的主要特性、确定橡胶圈和滑动表面之间的摩擦力、确定接触部分的作用力、确定参数PcV、计算碳圈的强度及其由工作液压力引起的变形。本文给出了安装在直径为 2 5、35和 45mm轴上的机械面密封结构的计算示例
The autonomous mechanical face seals covered in this article have been designed and tested at НИИСУ (Russian Aviation Institute for Standardization and Unification) and are designated for use in aeronautical technology products. Based on the work done in the past, the series of standards ОСТ1 1 3792 -80 ~ ОСТ1 1 380 1 -80 started to be implemented in the aviation industry. These standards include the typical structure and dimensions of the mechanical face seal structure and its components. This paper also gives a calculation method of the mechanical surface seal structure, showing the pressure and force profiles so that one can understand the forces acting on the components of the seal structure described above, such as the carbon ring, the wave spring, and the rubber ring. The mathematical formulas given in this paper can be used to calculate the main characteristics of a wave spring, to determine the friction between the rubber ring and the sliding surface, to determine the force at the contact, to determine the parameter PcV, to calculate the strength of the carbon ring and its pressure caused by the working fluid The deformation. This article gives an example of the calculation of a mechanical face seal mounted on shafts with diameters of 25, 35 and 45 mm
