摘要
挤压机主缸导套主要功能为定位和支撑主柱塞,并在主柱塞运动过程中起到导滑作用。本文从导套的功能要求、润滑原理、泄压通道要求和泄荷槽形式等方面说明了导套设计要求,并在此基础上根据动压要求、导套水平度要求和载荷要求三方面分别对导套长度进行研究,建立了导套长度和导套直径的函数关系,最后归纳了主缸导套的结构设计步骤。
The design requirements of the guide sleeve have been discussed in the text from the aspects of the functional requirements, lubrication principle, pressure relief channel requirement and the discharge groove form. On the basis of this, the guide sleeve length has been studied according to the requirement of dynamic pressure, the guide sleeve levelness and the load. The function relation between the guide sleeve length and the diameter has been established. Finally, the structural design steps of the guide sleeve for main cylinder have been summarized.
