MG463-WD型电牵引采煤机油缸的改进设计

Improved design for the cylinder of MG463-WD type electrical haulage shearer

油缸是采煤机液压系统的重要组成部分。因此 ,它的结构是否合理、参数是否匹配 ,对于整机的参数及使用性能均有重大影响。本文叙述了油缸的组成及工作原理 。

Cylinder is an important part of the shearer hydraulic pressure system.therefore, its structure is whether or not reasonable,its parameters are wether matchina, which have great influence in the parameters and useful capability of the shearer.This paper introduces the cylinder composition and working principle,analyses the shortcomings of the structure and puts forward corresponding solving measures.
