Experimental study on dynamic characteristics of Spur Planetary Gear

The sealed rotor system considering gear meshing characteristics is a complex mechanical system composed of gear pairs, rotors, seals and bearings, etc. its dynamic characteristics are very complex in operation. Due to the influence of many nonlinear excitation factors such as backlash, time-varying meshing stiffness and error, the dynamic phase characteristics of the system show strong nonlinearity. Therefore, based on the theoretical analysis of the system, corresponding experimental support is needed.

On the one hand, the rationality of the theoretical model can be verified; on the other hand, some problems reflected in the test can be expressed by using the theoretical model and the theoretical model can be modified, which is very beneficial to better research and improve the system performance.

Based on the theoretical analysis of the system, the dynamic model of the sealed rotor system considering the gear meshing characteristics is established, and the dynamic characteristics of the system are solved. The experimental results are compared with the theoretical results to verify the rationality of the theoretical model.
