The results indicate that, especially under a heavy load condition, the deflection of the stern shaft should be incorporated into the lubrication gap between the journal–rubber interface during the analysis of FSH performance of the JWR system. Welcome to the yard, and one of the first project of our season prep Ryan wanted to change the cutlass bearing, which was due for a replacement after 13 yea. In addition, to assess the effect of the force-driven deflection during FSH simulation, comparisons of the FSH predictions between the aligned journal case and the deflected journal case are carried out. To prove the correctness of the developed model, the predicted results are verified by comparisons with the experimental results given in the literature.
In the thermal analysis, the journal, water film, and rubber bushing are considered as an integrated system (JWR system) using the Euler method. In the FSH coupling model, the generalized average Reynolds equation and the Kogut–Etsion asperity contact model are used to determine the hydrodynamic and the elastic–plastic contact behaviors of WLRSB. Bronze rubber bearing, bronze rubber bush for water lubricant for marine industry.Naval brass rubber bush adapt equally well. The driveshaft is used to transfer torque between components that cannot be connected directly because of distance or the need to allow relative motion between them. These shafts as also known as driveshaft, driving shaft, tail shaft, or Cardan shaft. Made from specially formulated nitrile rubber bonded to Ultra High Molecular Weight Polyethylene (UHMW-PE) backing. The propeller shaft is a component used for transmitting mechanical power, torque, and rotation. Thordon RiverTough propeller shaft bearings operating in combination with hard coated nickel-chrome-boron sleeves are specially formulated to provide superior wear life in very abrasive water conditions and have proven their ability to last at least twice as long as rubber bearings. The novelty of the present study is that it investigates the effect of propeller shaft deflection, caused by the propeller self-weight and interfacial mixed forces, on the fluid–solid–heat (FSH) coupling performance of water lubricated rubber stern bearing (WLRSB). Tough, molded nitrile rubber bearing staves allow bearing change-out without shaft or propeller removal Bearing sizes available up to 36 inch shaft diameter over 2,000 installations operating worldwide ROMOR® I BEARING STAVES.
