Abstract: Aiming at the requirement of H-type hydrodynamic gas-lubricated bearing stiffness measurement, a bearing stiffness measurement system was established with high-precision capacitance sensor. A structural and temperature field analysis were given on the stiffness measurement equipment, and the stiffness measurement was improved. The self-weight method was used to measure the stiffness, and the results show that the improved measurement can meet the requirements of precision measurement of H-type hydrodynamic gas-lubricated bearing.

Key words: H-type hydrodynamic bearing, stiffness measurement, micro-motor
