Miniature bearing special measuring instrument, friction torque and high precision measuring instrument, research and development success

Miniature bearing friction torque and high precision measuring instrument developed miniature bearing USES a wide range, suitable for high speed, low friction torque, low vibration, low noise environment products, such as all kinds of industrial machines, small rotation, etc. Because of the miniature bearing diameter of axle size is very small, so the friction torque test to bring very great difficulty. Traditional measurement methods are prone to interference in the test process, test result is not stable, the data cannot automatically record, need skilled workers to be successful on a operation for many times, this way of measuring the bearing has apparently couldn't keep up with the development of speed. Against the status quo, neighbours instrument developed bearing friction torque measuring instrument, innovation using electromagnetic analytical balance technology, realize the high precision of miniature bearing friction torque test. Test, by loading device makes the bearing inside and outside the circle of relative movement, and to measure movement when the friction torque between the inner and outer ring. Device can measure the start of the miniature bearing friction torque; Under the bearing 2 RPM speed, rotate within two weeks, the measured minimum friction torque, maximum bearing friction torque, the average friction torque, and draw moment - Time curve, moment - Corner curve, speed Time curve. Fully automated test process, test precision is high. Torque measurement range of 0 ~ 100 mu N, m, torque measurement error of 1 mu N, m; Speed setting range of 0 ~ 4 RPM, speed measuring precision is 0. 5%F. 年代。 。 Equipment has automatic test data analysis and storage, the function of the automatic generation of test reports, for later analysis. The other have data management function, can be carried out on the test data query, playback, and delete. Miniature bearing equipment scalability is very strong, after minor modifications, suitable for deep groove ball bearings, roller bearings, needle roller bearings, thrust bearings and so on various types of bearing friction torque performance tests, in addition, also suitable for high precision pure mirror surface friction coefficient test.
