挖掘阻力是斗式卸船机的主要参数之一,它关系到各部件结构和功率的选择。通过挖掘阻力的试验与研究还可以得知有关斗型、斗距、挖掘速度以及其它各参数之间的关系。然而,要想测试出符合实际工况的挖掘阻力是十分困难的。下面介绍一种简便的测定挖掘阻力的“空斗法”。“空斗法”是把扭矩传感器布置在驱动轴上,从整机中拆除一个或n个斗(n的值尽量
Mining resistance is one of the main parameters of bucket-type ship unloader, which is related to the choice of structure and power of each component. Through the excavation of the resistance of the test and research can also learn about the bucket, bucket distance, mining speed and the relationship between the other parameters. However, it is very difficult to test the digging resistance that meets the actual conditions. The following describes a simple determination of mining resistance “air bucket law.” “Empty bucket method” is the torque sensor is arranged on the drive shaft, removed from the machine one or n bucket (n value as much as possible
