Abstract

The invention discloses a water-lubricated bearing online monitoring test platform. The platform comprises a variable frequency motor, a torque tester, a rotating shaft, a main rotating shaft, a speedreducer, a permanent magnet generator and the like. The variable frequency motor is connected with an electric control cabinet, a rolling bearing support is arranged on the rotating shaft, and a bearing system support, a non-contact electromagnetic loading device a and a non-contact electromagnetic loading device b are arranged on the main rotating shaft. According to the present invention, different information fusion characteristics of multi-source parameters are considered, so that the characteristics of the water lubricated bearings can be researched more conveniently. The invention alsodiscloses a bearing characteristic test analysis method. The method comprises adjusting the water supply pressure, the variable frequency motor rotating speed and the shafting load; measuring variousparameters, analyzing the energy supply mechanism of an energy collection system of the rotating machinery wireless devices and the communication quality of the energy collection system of the rotating machinery wireless devices; and analyzing the bearing friction characteristics, the lubricating characteristics and the lubricating mechanism. According to the invention, various performance tests of the water-lubricated bearings are perfected, and test data and scientific basis are provided for the safe and stable operation of the bearings, the design and manufacture of the bearings and the like.

Description

technical field [0001] The invention belongs to the technical field of state monitoring of electromechanical equipment, relates to an online monitoring test platform for water-lubricated bearings, and also relates to a test and analysis method for bearing characteristics. Background technique [0002] As an important component of underwater power machinery, water-lubricated bearings have a wide range of sources because their lubricants are directly obtained from water. What is important is that compared with oil-lubricated bearings, they will not pollute the environment due to grease leakage, and do not require complicated The lubricant supply system simplifies the mechanical structure, greatly improves the operational reliability, stable performance, and safe use. Therefore, it has been more and more widely studied and used in recent years. [0003] Water-lubricated bearings use water as a lubricant. Under certain conditions, a water film will form between the bearing and t...
