Description
Technical Field
The invention belongs to the technical field of ship propulsion mechanisms, and particularly relates to an injection-immersion combined lubrication system for a full-rotation rudder propeller.
Background
Along with the open sea development planning of naval vessels in China, the tonnage of naval vessels is continuously increased, the overall performance of the vessels is continuously improved, and higher requirements are put on the performance of the propeller, so that the propeller is required to be higher in efficiency and more energy-saving.
The full-rotation rudder propeller is used as one of main propulsion types of ships, and has the following functions: the power transmitted by the main engine is transmitted to the upper gear box through the shafting, is transmitted to the lower gear box through a pair of bevel gears in the upper gear box, is transmitted to the propeller shaft through a pair of bevel gears in the lower gear box, and is finally transmitted to the propeller through the propeller shaft. The free sailing and towing operation of the ship can be smoothly realized by being combined with a main machine-centralized control device. The navigation and steering of the ship are realized through the change of the rotating speed of the host machine and the steering oar direction.
The mechanical transmission of the full-rotation propeller is mainly completed by the spiral bevel gear, so the transmission efficiency of the spiral bevel gear pair and the bearing efficiency of the roller bearing determine the efficiency of the full-rotation propeller. The main factor affecting the transmission efficiency of gears and the efficiency of bearings is the lubrication mode. The lubrication system is used as a key technology in the production of full-rotation propeller equipment, and the performance of the lubrication system is also directly representative of the performance advancement of the propulsion system.
According to the specifications of American Gear Manufacturers Association (AGMA), the lubrication mode recommends several lubrication modes according to the tangential speed of gears, and when the tangential speed of the meshing part of the gears is more than 12m/s, the forced pressure lubrication mode, namely jet lubrication, is recommended, the mechanical transmission efficiency is high, the single-stage gear transmission efficiency can reach 99%, and the mechanical transmission efficiency of the whole set of propeller can reach 98%. Meanwhile, the rolling bearing also needs to be lubricated and radiated, and the lubricating system supplies lubricating oil to independent oil ways of all bearings at the upper gear box, so that the most reasonable and optimal lubrication of the roller bearing is achieved.
At present, several manufacturers engaged in full-rotation propellers at home adopt the following gear lubrication modes: a pair of bevel gears in the upper gear box body adopts oil drip lubrication, namely, lubricating oil drips onto a gear engagement surface through an oil hole formed above the gear, and a pair of bevel gears in the lower gear box body adopts immersion lubrication. The immersed lubrication, namely the gear is completely immersed in the lubricating oil, when the equipment is in operation, the mechanical transmission efficiency of the propeller can be influenced by a plurality of factors such as the heating of the gear and the bearing due to the viscosity, physical characteristics and the like of the lubricating oil, and according to technical parameters disclosed by domestic manufacturers, the single-stage mechanical transmission efficiency of the propeller adopting the immersed lubrication is about 96 percent and is far lower than the pressure type jet lubrication efficiency.
Therefore, a new lubrication system is needed to solve the above technical problems.
