一、引言近年来国内外生产的外啮合齿轮泵工作压力都有了较大的提高,从70—140kgf/cm~2提高到160～250kgf/cm~2,结构设计上也有了许多新发展,其中常采用的扩大高压区的结构,就是为了降低轴承负荷,改善轴向平衡条件,从而提高泵工作压力的一种方法。由于这种结构简单易行,因而在实际设计中已被应用。如何计算扩大高压区的齿轮泵的轴承负荷,就是本文所讨论的内容。
I. INTRODUCTION In recent years, the working pressure of external gear pump produced at home and abroad has been greatly improved, from 70-140kgf / cm ~ 2 to 160 ~ 250kgf / cm ~ 2, there have been many new developments in structural design, Often used to expand the structure of the high pressure zone, is to reduce the bearing load, improve the axial balance conditions, thereby increasing the working pressure of a pump. Because of this structure is simple and easy, so in the actual design has been applied. How to calculate the expansion of the high-pressure zone gear pump bearing load, is the content of this article.
