轴承密封 meaning in English

bearing seal
seal of bearing

High speed journal seal of cone bit design and finite element method analyze
高速牙轮钻头轴承密封副设计与有限元分析
The recent development trend of cone bits is to realize their high speed . faster the speed of bit is , the more weak of common bearing seals worked under the rough environment is
牙轮钻头目前的发展趋势是实现高速化，随着钻头转速的不断提高，在恶劣环境下工作的普通轴承密封这一环节的薄弱性将显得越来越突出。
According to achievements in research , using face - radial sealing structures can adapt to the developing trend of increasing rotary speed of cone bit to a certain extent in lubricating system of bearing seal , which is cramp to bit service life
本文的研究表明，在伟l ]约钻头寿命的轴承密封润滑系统中，采用端面一径向组合密封结构能够在一定程度上适应牙轮钻头转速提高的发展趋
To enhance the reliability of bearing seal of cone bit , this paper plans to adopt face - radial combination sealing structures ; that is to say , end - face and radial seal are arranged in one bit simultaneously . the nonlinear finite element method is applied to analyze and optimize the design of sealing structures
为了提高牙轮钻头轴承密封的可靠性，本文设计采用端面-径向组合密封结构，即在一只钻头中同时布置端面和径向密封，采用非线性有限元方法对密封结构进行分析和优化。
