用超声波传感器检测诸如起重机、挖掘机等重型设备的大型滚动轴承时,无须将轴承拆下来,只要将传感器置于轴承圈内,便能“查看”轴承滚道(图1)。通常在每一个需要检测的表面都需装设一传感器。虽然在新轴承内设置此种传感器最易处理,但某些现有的轴承,若有适于装设传感器的空间,也可作适当改进 With ultrasonic sensors for detecting large rolling bearings such as cranes, excavators and other heavy equipment, there is no need to disassemble the bearings and “view” the bearing raceways (Figure 1) simply by placing the sensor in the bearing ring. Usually need to install a sensor on each surface to be tested. Although this type of sensor is most easily handled in a new bearing, some of the existing bearings may have suitable modifications if space is available for mounting the sensor
