AI Technical Summary
When conducting rotor dynamics tests in a vacuum environment, the rotor rotation does not generate axial force, causing the rolling bearings to slip due to insufficient axial force, thus failing to simulate actual working conditions.
An axial force adjustment device was designed. By using a support box and an axial force adjustment assembly, and by employing components such as hydraulic cylinders and angular contact ball bearings, a forward or backward axial thrust is applied to make the test rotor obtain an axial force consistent with the actual situation.
This ensured that the axial force on the rotor was consistent with the actual situation, solved the slippage problem of rolling bearings caused by insufficient axial force, and ensured the accuracy of the test results.
