SENSOR ASSEMBLY AND SENSOR SYSTEM FOR COMBINED BEARING LOAD SENSING AND BEARING HEALTH MONITORING

摘要

The present invention relates to a sensor assembly for measuring a load on a bearing having at least one bearing ring , the at least one bearing ring has a cavity 12 for holding the sensor assembly . And the sensor assembly comprises a series of fixtures between the opposing sides (17 , 18) of the cavity (12) , said mounting fixture comprises a set of piezoelectric plate 16 and the spring stiffness k of the spring 13 . Alternatively, the sensor assembly is by further comprising a main body 14 disposed between the mass m of the piezoelectric plate 16 and the spring 13 , the load measurement can be carried out at the same time as the condition monitoring .
