Background technology
The resource of current land is day by day deficient due to long-term use, and many areas in the world there occurs " energy
Source crisis ".In order to solve this global problem, the mankind just turn to ocean sight, are devoted to the exploitation to marine resources.Sea
Ocean is the hope of mankind's 21 century, and ocean is richly endowed and the natural resourcess treasure-house of not fully exploitation, and exploitation marine resources become generation
The Major Strategic direction of various countries of boundary development, in order to preferably carry out the exploitation of marine resources and the maintenance of maritime rights and interests, ship work
The development of industry is that the important technology realizing ocean power strategy supports.In recent years, multiple countries such as Australia, Japan, Korea S
The strategic plan to marine resources development all in strengthening, increases the input of marine engineering equipment fund and the application of new and high technology,
With marine industries group beautiful, that the developed country as representative for the day has been set up huge structure, pay much attention to the exploitation of marine resources.
Ocean is the important substance basis of economic globalization, achieves 90% world commerce, ocean according to statistics by ocean
The lifting of development technique makes world economy and trade become increasingly dependent on marine resources.China's economy has developed into ocean height at present
The export-oriented economy that degree relies on, is greatly improved to the degree of dependence in marine resources and space, and therefore China proposes the war of ocean power
Slightly.For realizing ocean power strategy, propose with shipborne equipment, marine engineering equipment, high-tech in shipping industry development plan

The no key interference of rotation oar axle connects catastrophic failure and causes serious marine accident；If the magnitude of interference that propeller no key is installed is relatively
Greatly, the mating surface of propeller and propeller shaft can in conjunction with closely, suffered by propeller material, stress also improves therewith, may
The yield stress of material can be exceeded, when serious, propeller inner surface crackle and has to scrap, the reliable operation of propeller
Property and service life directly affect the life security of navigation safety and crewman and passenger, the therefore installation quality of propeller becomes
For the important step during shipbuilding.
The propeller of large-scale new ship adopts oil pressure no key to install mostly both at home and abroad at present, and it is by propeller boss
The oil groove of inner surface is passed through radial high-pressure oil, makes propeller boss produce expanded radially deformation in the elastic range of material, simultaneously
It is passed through axial hydraulic oil to hydraulic nut, the piston of hydraulic nut produces axial thrust to propeller boss, when propeller boss and spiral shell
The relative displacement of rotation oar axle reaches no key and installs release loading oil pressure, final propeller and propeller shaft shape during the required amount of pushing
