What is a smart bearing? Smart bearing what advantage is there?

What is a smart bearing? Bearing as the 'joint' machine, defining intelligent bearing before, to explain the 'smart' machine. The interpretation of the smart machines is also very much, most with color in the future. Definition of intelligent machines for: 'use sensors to monitor and adjust its running environment, in the uncertain and variable machine' of a particular task. Intelligent machine is a kind of mechanical system can realize self 'take care', but also not to say that the intelligent machine maintenance ( Future dream) , but instead USES its built-in intelligence programs to detect a potential problem and simplify maintenance intervals and procedures. Similarly, there are a variety of claims for definition of smart bearing, xi 'an jiaotong university research team to define it as: on the basis of traditional bearing integrate different USES of sensing device and control device, make its combined together to form a unique bearing structure unit, the use of information processing, automatic control technology such as bearing running status real-time online monitoring, fault detection and real-time control. Smart bearing what advantage is there? 1, self awareness: based on the micro sensor technology integrated rotation speed, vibration, temperature, load and lubrication condition served multi-source information gathering sensing device, sensor integration degree is high, it can realize external ring, inner ring, cage and even roller service information monitoring and identification, high degree of information coverage; Due to the sensor directly integrated in the bearing body, high signal-to-noise ratio of monitoring signal can be more sensitive, more early to detect and bearing status of the equipment. 2, since the decision: based on the massive bearing service data, combined with large data and deep learning technology, extract information service characteristics of bearing health condition, identify the current operation state and trend of bearing historical data, assess the health service of bearing, for possible abnormal conditions make warning of judgment. 3, since the regulation: serving in the bearing condition monitoring and evaluation on the basis of diagnosis, combining state of rolling bearing service mechanism research, through lubrication dose, cooling parameters, preloaded state and working, Such as speed, cutting the amount) Adjust the service state of rolling bearings, such as improving the safety and reliability of the major equipment service and maintenance can be unexpected. Since the 1980 s have brands research intelligent bearing ( Also known as a sensor bearing) And is mainly used for automobile ABS system. Through to the bearing rotating speed, temperature, vibration and load monitoring, analysis of data, to form a feedback. International famous bearing company has been in constant progress in the research of intelligent bearing. Human wisdom is infinite, with the emergence of intelligent bearing, means that industrial technology has increased a step, the era of high-tech intelligent is not a dream, also in actively undertake research in our country, the instructor of colleges and universities students have been exploring, for bearing, mainly is for embedded intelligent bearing signal acquisition, monitoring and analysis, etc. Trust, innovation, on constantly attempt, ready, when technological breakthrough, application demand, can really stand in the forefront of industry.
