The testing platform for axial direction preload of automobile hub bearing

    • The testing platform for axial direction preload of automobile hub bearing performance


      The axial preload test platform for axial preload of automobile hub bearing get the resonant frequency and damping coefficient between the inner circle and outer circle of the hub bearing unit by using resonance method, according to the hertzian contact theory. It determines the pre-load of automobile hub bearing by calculating and analyzing of the software program.

      Main technical parameters:

      Testing type: bearing unit of automobile hub
      The maximum shape of testing bearing (Φ×H):200×150 mm
      The maximum mass of testing bearing: 5kg
      The range of excitation frequency: 200~3000Hz(resolution 1Hz)
      Maximum amplitude: ±5mm
      Maximum excitation force: 15kg
      Test parameters: resonant frequency and damping coefficient
