Abstract
Temperature is one of the most important parameters affecting the service life and performance of rolling element bearings. Based on the temperature sensitive properties of quantum dots (QDs), a non-intrusive temperature measurement method is developed to monitor the temperature variation of the inner ring and cage during bearing operation. The CdTe QDs were synthesized in our laboratories and used in constructing of a sensor film by means of Layer-by-layer Electrostatic Self-assembly method. The fluorescence spectrum properties of the sensors were characterized. The experiment was performed to measure the inner ring and cage temperature of angular contact ball bearing in high speed running condition. Bearing inner ring and cage temperature rise curves were obtained in this paper by the CdTe QDs sensors and compared with the outer ring temperature gotten by platinum thermal resistance sensors.
