Description

technical field [0001] The invention relates to the field of marine counter-rotating full-turn thrusters, in particular to an oil injection lubrication and cooling system for high-power counter-rotating full-turn thrusters. Background technique [0002] At present, domestic marine counter-rotating azimuth propellers generally adopt the traditional oil immersion method to lubricate and cool the rotating mechanisms such as gears and bearings, that is, directly immerse the gears, bearings and other transmission mechanisms of the azimuth propeller in lubricating oil. Lubrication and cooling, the traditional oil immersion method for lubrication and cooling has the following disadvantages: [0003] 1. Using the traditional oil immersion method for lubricating and cooling, it is necessary to maintain a certain level of lubricating oil in the gearbox, so it is impossible to provide lubricating oil for each lubrication point according to actual needs; [0004] 2. The oil of oil-imme...
