Abstract

The invention relates to a test device for simulating a rotor rubbing fault, belonging to the technical field of rotor rubbing tests. The test device aims to solve the problems that an existing test device cannot adjust the contact depth between a rubbing contact part and a rotor, cannot simulate a rubbing fault weak to be serious and cannot perform one-way simulation of the rubbing fault. A motorand a rubbing device are fixed on a working platform, center lines of the motor and the rubbing device are located on the same straight line, the output end of the motor is connected with one end ofa rotating shaft through a coupler, the other end of the rotating shaft sequentially passes through a first bearing block, the rubbing device, a disc and a second bearing block, and the first bearingblock and the second bearing block are fixedly mounted on the working platform. The test device for simulating the rotor rubbing fault can adjust the rubbing contact part through a plurality of adjusting bolts, so that rotor rubbing faults of different depths in multi-local face contact are simulated precisely.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for simulating a rotor rubbing failure, and belongs to the technical field of rotor rubbing tests. Background technique [0002] In actual engineering, rotor rubbing is a common typical failure of rotating machinery such as gas turbines, aeroengines, and steam turbines, which will cause large vibrations in the entire machine, reduce its reliability and stability, and cause huge economic losses. Therefore, the establishment of a rotor system friction rubbing fault test simulator to study the internal mechanism of typical rotor rubbing faults has great engineering practical significance and guiding role. However, the existing test devices cannot achieve partial surface contact, which is somewhat different from the actual situation. The impact of the test data is very large, and at the same time, it cannot realize the contact from single surface to multiple surfaces, and cannot provide...
