Abstract

The invention relates to a marine bearing swing test device. The test device comprises a swing inclination test device. The swing inclination test device comprises a test bench. The marine bearing swing test device comprises a space loading inverted bearing experiment table. The space loading inverted bearing experiment table comprises a driving motor, a transmission shaft, an unloading mechanism,a test shaft, a flexible loading device and a bearing support group. The lifting mechanism comprises a flexible part, a first telescopic cylinder and a second telescopic cylinder, one end of the flexible part is connected with the driving end of the first telescopic cylinder, the other end of the flexible part is connected with the suspension assembly, and the driving end of the second telescopiccylinder is supported in the middle of the flexible part; the bearing support set comprises a left bearing support and a right bearing support, the right bearing support faces one side of the transmission shaft, bearings are arranged in the left bearing support and the right bearing support respectively, the bearing in the left bearing support is movably assembled, and the bearing in the right bearing support is fixedly assembled. According to the invention, the flexible change of the load applying direction is realized, and the accuracy of the test result is ensured.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship bearing swing test device. Background technique [0002] Sliding bearings can achieve high-speed operation with large loads, long life and high reliability, so they are commonly used in some large equipment, such as large marine motor sliding bearings, large steam turbine main shaft bearings, nuclear main pump bearings, etc. With the development of the national economy, the demand for this type of bearing is becoming more and more extensive. These bearings have common characteristics: large load, high speed, high reliability requirements, and belong to high-end sliding bearings. When researching and developing this type of bearing, it is necessary to carry out performance tests of all working conditions. For this reason, it is necessary to develop a performance test bench for all working conditions, and the performance test bench for all working conditions must meet the req...
