Rotating part axial force loading system comprising rotor and stator difference axis fault-tolerant ability

Abstract

The invention relates to a rotating part axial force loading system comprising a rotor and stator difference axis fault-tolerant ability. A rotor is arranged on a rotor test device, a test bearing sleeves on outside of the rotor, and is arranged in a bearing pedestal. The system comprises an actuator cylinder, a forcemeter, a rotor and stator convertor, a first universal ball joint connecting rod, a coupling, a second universal ball joint connecting rod, a convert bolt and a load-bearing frame. The actuator cylinder brings an acting force to transmit the acting force to the rotor and stator convertor, the first universal ball joint connecting rod, the coupling, the second universal ball joint connecting rod and the convert bolt in order, and finally, the acting force is transmitted to the rotor and the test bearing. The loading system has simple structure and stable load, and the load system can realize the shaft rotation with the difference axis fault-tolerant ability through the rotor and stator convertor.

Description

technical field [0001] The invention belongs to the technical field of aero-engine testing, and in particular relates to an axial force loading system for a rotating part with the ability to tolerate misalignment of the rotor and stator. Background technique [0002] In the aero-engine rotor test, due to the aerodynamic load can generate a large axial force, acting on the thrust bearing, even up to tens of tons, far beyond the bearing range of the thrust bearing, it is necessary to balance this axial force, so that Thrust bearing force is within a reasonable range. In the bearing characteristic test (such as the radial dynamic compliance of the thrust bearing), it is necessary to apply a certain axial force to the thrust bearing to eliminate the axial clearance of the thrust bearing and to approach the real working state. These tests require a Axial force loading system. [0003] The current loading system is: install the rotor and the bearing on the rotor tester, use a sy...
