液压技术是当前的一门新技术。研究它的技术特点并把它应用于采矿工业,会使矿山生产技术发生全新的变化。本文试就低速大扭矩矿用液压马达的应用谈谈以下几个问题。一、矿山机械对驱动机构的要求冶金矿山机械长期在粉尘、潮湿、腐蚀、振动等复杂环境中工作,这就对其驱动机构提出了一系列的要求: (一)大扭矩和低转速。由于外负荷较大,机械的输出扭矩必定也大,但要求的输出转速不高。矿山机械的工作转速多在100(转/分)以内,如装载机的车轮、挖掘机履带的链轮、钻机的钻杆、运
Hydraulic technology is currently a new technology. Studying its technical characteristics and applying it to the mining industry will make a totally new change in the technology of mine production. This article tries to talk about the application of low speed high torque mining hydraulic motor to talk about the following questions. First, mining machinery on the drive mechanism requirements Metallurgical mining machinery in the dust, humidity, corrosion, vibration and other complex environment for a long time, which drives its institutions put forward a series of requirements: (A) high torque and low speed. Due to the larger external load, the mechanical output torque must also be large, but the required output speed is not high. Mining machinery working speed more than 100 (rev / min) less, such as the wheel loader, excavator crawler sprocket, drill pipe, transport
