摘要
传统的煤矿坑道液压钻机的传动系统,只能通过改变动力头减速器配对传动齿轮,利用不同的传动比实现钻机工作转速的调节,整个系统几乎属于定量系统,这样钻机在工作时不能根据被钻进煤岩的硬度自动调节速度。现有传动系统已经采用变量泵和变量马达调节转速。在现有变量系统基础上进行传动系统的分析,从而对传动系统进行合理优化。
The traditional coal mine tunnel hydraulic drive system of drilling rig,only by changing the power head matching gear speed reducer,with different ratio can adjust speed of drilling rigs,the whole system almost belong to quantitative system,this drill will not be able to at work according to the hardness of the coal and rock drilling automatically adjust speed,transmission system be adopted for already existing variable pump and variable motor.Analyzes the transmission system on the basis of the existing variable system.
