一、前言 橡胶“O”形圈是一种通用密封件,可用于静密封结构和动密封结构,可密封来自任何方向上的介质压力。 А·С·Косенкова等人通过对密封件工作机理的研究,确定了接触压力是决定密封性能的主要参数。橡胶“O”形圈的密封能力取决于初始接触压力和对介质压力的传递以及橡胶可逆变形的恢复速度。
I. Introduction Rubber “O” ring is a universal seal, can be used for static seal structure and dynamic seal structure, can be sealed from any direction of medium pressure. А · С · Косенкова and others through the working mechanism of the seal to determine the contact pressure is to determine the sealing performance of the main parameters. The sealing ability of a rubber “O” ring depends on the initial contact pressure and on the pressure of the medium and on the recovery rate of the rubber reversibly deformable.
