文章对BC500GY固井压裂车变速箱的液控湿式盘式摩擦离合器的设计计算、设计参数和摩擦片材料的选择作了比较详细的阐述。该型变速箱离合器通过500小时台架试验、180小时型式试验以及油田多井次的作业表明,传动平稳、效率高,动力换档准确、可靠,使用寿命较高、耐用。文后又对使用中应注意的几个问题作了介绍,供参考。 This article elaborates the design and calculation, design parameters and the selection of friction lining materials for the liquid-controlled wet disc friction clutch of the BC500GY cementing fracturing truck gearbox. This type of gearbox clutch passed 500 hours of bench test, 180 hours of type test and multi-well operation of the oilfield shows that the transmission is stable and efficient. The power shift is accurate and reliable, and the service life is high and durable. After the article also should pay attention to the use of several issues were introduced for reference.
