ZYS The testing platform for axial direction pre-loading of TAUh30-50 automobile hub bearing
The testing platform for axial direction pre-loading 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
