一种新密封结构的设计及应用

Design and Application of a New Sealing Structure

在液压流体传动系统中,ISO 6149内锥面密封结构因其密封效果好而被广泛应用,但这种密封结构存在锥面孔较难加工,安装时易切密封圈等不足,提出一种新密封结构的设计方法。通过对比ISO 6149内锥面密封结构,对密封原理、特点及优越性做了详细分析,并给出密封参数确定方法,通过实际运用和仿真进行了验证。

In hydraulic fluid transmission systems,ISO 6149 inner cone sealing structure is widely used because of its good sealing effect,but this sealing structure has some shortcomings,such as cone hole is difficult to process,easy to cut the seal ring during installation,so a new sealing structure design method is proposed in this paper,through the comparison of ISO 6149 inner cone sealing structure,the sealing principle,characteristics and advantages of this type of sealing structure and method to determine the sealing parameters is given,the application is verified by practical application and simulation.
