Detachable lath type water lubrication stern bearing performance test bench

Abstract

The invention discloses a detachable lath type water-lubricated stern bearing performance test bench, and relates to the field of test equipment. The test bench comprises a water-lubricated bearing base and a water-lubricated bearing, wherein a stern shaft is arranged in the water-lubricated bearing in a penetrating manner, one end of the stern shaft is arranged on a loading mechanism in a penetrating manner, and the other end of the stern shaft is connected with an intermediate shaft through a coupling; the end, away from the stern shaft, of the intermediate shaft is connected with a motor which is fixedly arranged on a motor support; an intermediate bearing is arranged on the intermediate shaft in a penetrating mode and installed on an intermediate bearing support. The bottom and one side of the loading mechanism are respectively connected with a hydraulic cylinder through a loading bracket; the water-lubricated bearing is uniformly drilled at different positions in the axial direction and different angles in the circumferential direction and provided with a plurality of water film pressure sensors, and eddy current displacement sensors perpendicular to one another are installedon the same section of the water-lubricated bearing. The water lubricated bearing is installed in a bearing sleeve, and the end of the bearing sleeve is connected with a circulating water system. Thetest bench can truly simulate the complex working conditions of the water-lubricated bearing, and is convenient to disassemble.

Description

technical field [0001] The invention relates to the field of test equipment, in particular to a detachable slat-type water-lubricated stern bearing performance test bench. Background technique [0002] At present, bearing friction pairs are usually lubricated by oil in mechanical transmissions and made of metal components. Therefore, this not only consumes a large amount of important strategic resources such as precious metals and mineral oil, but also fundamentally causes oil leakage pollution, etc. serious environmental problem. [0003] Water has the advantages of large specific heat, low viscosity, small frictional resistance and low friction coefficient. The cooling efficiency of the bearing will be higher and the temperature rise will be more stable. Using water as a lubricating medium to lubricate sliding bearings is not only environmentally friendly, The damage to the ecological environment can be well avoided, the structure of the rotor system can be simplified, an...

Problems solved by technology

[0004] However, the current technology has many imperfections in the design and testing of water-lubricated bearing test benches

For example, the invention patent named water-lubricated rubber bearing performance test bench (application number: 201820282719.2, application date: 2018.02.28) discloses a water-lubricated bearing test bench. The size of the water-lubricated bearing test bench is too small, and the load It is not big enough to truly and completely simulate the actual operating conditions of water-lubricated bearings, and it cannot be disassembled. Water-lubricated bearings cannot be replaced after they are worn out. Therefore, it is necessary to design a large-scale water-lubricated bearing test bench that is close to the size of the actual ship and is easy to disassemble.
