12CM15型连续采煤机截割齿轮箱内部结构缺陷及改造

12CM15 Type Continuous Miner Cutting Gear Defects and Transformation of Internal Structure

在连续采煤机大修过程中,发现截割齿轮箱内部齿轮磨损严重,不能重复使用,经过分析发现,截割齿轮箱内部的齿轮轴及固定部分存在设计缺陷,使内部齿轮磨损严重,故对12CM15型连采机截割齿轮箱内部结构缺陷进行分析并提出改造方案。

In the process of overhauling continuous miner was found within the gear cutting gear wear serious,can not be reused,after analysis found that cutting the long axis of the internal gear box and fixed some design flaws,so that a serious internal gear wear,so on 12CM15 cutting type continuous miner defects of the internal structure of gear box analysis and transformation programs.
