How to lower the rise of temperature of the machine tool spindle bearings, not watch knowledge!

As we all know, the market in recent years more and more high to the requirement of machine tool spindle, and improve performance of each component and the individual components in the configuration of machine tool is the key to lifting machine itself characteristic, therefore, the spindle properties, such as high speed, low temperature rise has become a key, low temperature rise is an important technology of the spindle bearing should have, then how can we do to reduce the rise of temperature of the machine tool spindle bearing? Below, you can with the author to get to know it. One, bearing the internal temperature field visualization 1, despite the low temperature rise for machine tool spindle bearings or plain bearing is a key technology, but for the bearing in the process of rotating the understanding of internal temperature is not too much. 2, bearing the hot zone including the inner ring with roller and cage with outer ring and cage with sliding contact part between the roller and outer race and rolling body each rolling contact between parts of the sliding contact, measure these areas would be very difficult. 3, usually used to measure such as bearing temperature of measuring device. Use slip rings and brush contact transmission thermocouple signal, therefore can use the speed limited. In addition, although can measure temperature of the inner ring, but cannot measure the bearing temperature of the internal parts, such as cage and rolling body. 4, as measured in the use of infrared thermometer in cage and rolling elements such as narrow set of points in the area, so the temperature is measured in these areas is a challenge. Second, reduce internal heat 1, in order to find the ceramic ball bearing as a rolling element bearing the influence factors of internal heat production, with gao min thermal imaging system measuring the internal temperature of bearing. Using constant pressure preloading method, it is a kind of similar to the structure of machine tool spindle. In addition, there is a large opening in the end of the spindle, in order to look inside the bearing. 2, measuring the intensity of infrared thermal imaging technology, and transformed into temperature. If there are similar to the reflection of the interference, is difficult to get accurate temperature measurement, therefore, design a variety of methods to eliminate the influence of bearing, to realize the precise measurement of temperature. 3, is the temperature of bearing roller components, outer ring and cage and rolling element on the measurement result as a typical data, speed setting for the parameter, the bearing internal temperature measurement result of each point in all speed rolling body temperature, and increased with the increase of rotational speed. 4, in order to confirm the standard bearing, the internal temperature of the heating forecast system, optimize the design of the cage and the corresponding clearance after less as compared to the measured results of warm color, confirmed that the internal temperature of the bearing has fallen, in other words, based on heat prediction optimization of bearing, bearing temperature rise reduced, proved that is applied to the analysis of heating technology effectively. Above is the author explain for everybody about how to reduce the whole content of the rise of temperature of the machine tool spindle bearings, hope you have read will help, to sum up, the development of low temperature rise to improve the machining accuracy of machine tool spindle bearings and high speed performance, more help to improve the precision, processing quality and efficiency of the host, jiaxing bearing note in the machine tool spindle bearing and other series of bearings for many years, has a perfect after-sales service team, in a timely manner to solve customer's questions, in order to avoid the trouble back at home, welcome to call the advisory.
