Description
Technical field
The utility model relates to device for ships, relates in particular to the improvement of the intermediate bearing structure that is used to support the marine propulsion shafting jack shaft.
Background technique
In recent years, the boats and ships The Enlargement Tendency is remarkable day by day, and main engine power also increases thereupon, used main frame on the oversized container ship for example, and its power has reached 60,000～100,000 kilowatts, and this makes the diameter of axle of marine propulsion shafting significantly increase; On the other hand, propeller cavitation will obtain high efficiency, its rotating speed is more and more lower, diameter of propeller blade is tending towards increasing, corresponding propeller cavitation weight is tending towards more and more heavier, and also causing cardan shaft is that the diameter of axle increases, and these all make the weight of axle increase along with the increase of the diameter of axle, the corresponding raising of bearing capacity that this just requires bearing promptly needs to use big specific pressure intermediate bearing.
Chinese patent application (application number 200820032898.0) has proposed the big specific pressure intermediate bearing of a kind of sphere self-alignment formula, and the major technique feature of this patent application is on the axle supporting surface of bearing shell macromolecule graphite liner to be installed.On bearing shell, the intermediate bearing of this structure has the following disadvantages this liner by screw: (1) is because the graphite liner by screw, repairs inconvenience; (2) because the axle supporting surface screwing of bearing can not be a lot, thereby the graphite liner is divided into several is fixed on the bearing shell, also will be changed when the graphite liner that this has in causing keeping in repair has only the small part wearing and tearing and cause waste by full wafer.(3) concentricity requirement of hole on the graphite liner and the screw on the bearing shell is higher, and the perpendicularity requirement of screw is also higher on the bearing shell, causes the processing cost height.
The model utility content
Technical problem to be solved in the utility model provides a kind of big specific pressure intermediate bearing peculiar to vessel, and this big specific pressure intermediate bearing is easy to maintenance, user cost is low.
The scheme of the utility model technical solution problem is: this big specific pressure intermediate bearing peculiar to vessel, comprise divided bearing shell frame and the bearing shell that is installed in this cartridge housing frame, be distributed with the macromolecule graphite liner of sheet on the axle supporting surface of this bearing shell, adjacent two macromolecule graphite liners interconnect by tenon and tongue-and-groove.
After adopting such scheme,, save the screw procedure, lay easily and fast because adjacent two macromolecule graphite liners link together by tenon, tenon groove structure.And can do the macromolecule graphite liner of monolithic narrowly, during maintain and replace as long as change the macromolecule graphite liner sheet material of serious wear, mild wear or can not changing of wearing and tearing not, saving macromolecule graphite liner sheet material.And the macromolecule graphite material of bearing shell liner, because of it has the intensity height, the characteristics that wear-resisting property, resistance to high temperature, decay resistance and self-lubricating property are good have improved high temperature resistant, the wear-resistant and self-lubricating property of bearing shell from material.
In sum, the transmission shaft that this model utility can support that the diameter of axle is big, axle body is heavy, and manufacturing, easy to maintenance, user cost is low.
