Abstract: With the growing requirement of high reliability of the intershaft bearing of aircraft-engine, the fundamental research of this kind of product life is needed. A test rig has been developed to simulate behavior of this kind inner shat bearing. The test rig has the functional features of automatic controls of oil temperature, rotational rate and load, and automatic alarming. The structure and functions of the test rig are introduced, and its high-speed performance is tested. Results show that the test rig can meet the requirements to test the performance of the intershaft bearing of aircraft-engine working in real and complex conditions, the test process can be automatically controlled, the procedure parameters can monitored and stored in real-time. This test rig can be used as a basic testing platform of inner shat bearing of aircraft.

Key words: mechanical design, aircraft-engine intershaft bearing, test rig, condition monitoring
