Research for the Bearing Grinding Temperature On-Line Monitoring System Based on the Infrared Technology

On-line monitoring to temperature of grinding arc is an important link absolutely necessarily in bearing grinding automation. This paper introduced a new method, which is to monitor grinding temperature via infrared ray, designed the engineering model of grinding arc temperature on-line monitoring system, and presented with components of grinding temperature automatic detection system and made analysis to workflow of the system. It brought forward the thought to establish factory grinder and central monitoring room to constitute local area network so as that the central monitoring room could transfer information as grinding dosage and finishing of grinding wheel to operators of each grinder. Through analysis to influential factors of measurement results of that system, the paper provides with solutions. Technical tests validate that relative measurement error of that system is less than 0.5degC, which could better achieve on-line monitoring and alarm of grinding temperature and promote surface quality and productivity of grinding parts significantly.
