Based on 170SD30-SY without inner ring ceramic spindle rotor has the excellent characteristics of light weight, wear resistance and high elastic modulus, simulating and analysing the vibration displacement of the front spindle under different pre-tightening force. Using ANSYS to solve the friction of the bearing temperature which is caused by pre-tightening force and import the temperature rise into the entire model in which to study the distribution of the whole temperature field. Calculating the service life of the bearing in different conditions with the pre-tightening force. Based on the above analysis and different conditions, choosing a reasonable pre-tightening force, at the same time, using this preload carried out to measure vibra-tion and temperature rise experiments, comparing the results with the simulations, thus proving the correct-ness of simulations and the selected preload.
