Spindle bearing relevant study

• Bearing stiffness analysis and measurement, application of Hertz contact theory, establish the formulations for calculating the stiffness of precision spindle bearings, bearing stiffness characteristic analysis and example calculation, measurement and processing computer system of vibration, vibration feature extraction of signals, the measurement of the stiffness of the bearing.

• Dynamics analysis of spindle units,according to the theory of vibration, the application of the finite difference method and the finite element method, the dynamic characteristics of spindle slewing drives is analyzed, and an example of calculation.

• To calculate the minimum preload, put forward the minimum preload bearing calculation criteria, and an example of calculation.

• Bearing speed experimental study, effects of test to bearing structure and lubrication parameters on the performance of speed.
