Abstract
The utility model relates to a mechanical device for ship, in particular to an improvement on a neck bearing supporting the propeller shaft system of the ship in the middle. The utility model comprises a splint bearing shell frame and a gap block pedestal ring connected with the bearing shell frame; the inner hole wall of the gap block pedestal ring is a cylindrical hole surface; at least two strip macromolecular gap blocks with same shapes and sizes are arranged on the inner hole wall; the strip macromolecular gap blocks are mutually connected into a circle; and the contact surface between the neighboring strip macromolecular gap blocks is a plane. The large specific pressure neck bearing for ship has the advantages of easy manufacture, convenient maintenance and low maintenance cost.
Description
Technical field
The utility model relates to seaborne machinery, relates in particular to the improvement of the intermediate bearing of supporting marine propulsion shafting.
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 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, will be dismantled the upper bearing (metal) shell during maintenance, time-consuming 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 serious wear 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, and difficulty of processing causes the processing cost height greatly.
Chinese patent application 200820035985.1 has proposed the big specific pressure intermediate bearing of another kind of structure, the major technique feature of this structure is the macromolecule graphite liner that the tenon groove structure of sheet is installed on the axle supporting surface of bearing shell, and adjacent two macromolecule graphite liners link together by tenon and tongue-and-groove.The intermediate bearing of this structure has the following disadvantages: (1) this sheet macromolecule graphite material is thinner, fractures easily in the maintenance process, ftractures; (2) the tenon groove structure more complicated in course of working on the macromolecule graphite liner, conformity is not fine, occurs cooperating inexact phenomenon in the use easily; (3) processing cost of the macromolecule graphite sheet material of tenon groove structure is than higher.
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 peculiar to vessel makes easily, easy to maintenance, and maintenance cost is low.
The scheme of the utility model technical solution problem is: a kind of big specific pressure intermediate bearing peculiar to vessel, comprise divided bearing shell frame and the bearing shell seat ring that is connected with this cartridge housing frame, the inner hole wall of this bearing shell seat ring is the cylindrical hole face, at least be distributed with the two block-shaped bar polymer graphite bearing shells all identical on this inner hole wall with size, described bar polymer graphite bearing shell constitutes a circle mutually, and the surface of contact between the adjacent bar polymer graphite bearing shell is the plane.
Owing to adopt such scheme, make the arc length of axle supporting surface of single bar polymer graphite bearing shell less than the arc length of itself and bearing shell seat ring surface of contact, thereby be able to mutual support between the adjacent bar polymer graphite bearing shell, constraint mutually, need not screw, do not need to rely on the tenon groove structure on the macromolecule graphite bearing shell to retrain mutually and support yet, and owing to got rid of the formed curvecd surface type end face of tenon groove structure, make manufacturing process simpler, cost is lower, on the other hand because bar polymer graphite bearing shell is thicker, thereby can do narrowly, need only the bar polymer graphite bearing shell of changing serious wear during maintain and replace, mild wear or can not changing of wearing and tearing not are to save bar polymer graphite bearing shell.The phenomenon that bar polymer graphite bearing shell fractures, ftractures can not appear in maintenance process yet.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the plan view of the structural representation of a kind of specific embodiment of the utility model.
Fig. 2 is the left view of structure shown in Figure 1.
Fig. 3 is the plan view that bar polymer graphite bearing shell amplifies in the structure shown in Figure 1.
Fig. 4 is the plan view that bar polymer graphite bearing shell amplifies in the structure shown in Figure 1.
Embodiment
Fig. 1, Fig. 2, Fig. 3, among Fig. 4, in the divided bearing shell frame 1 bearing shell seat ring 2 is housed, the inner hole wall of this bearing shell seat ring 2 is the cylindrical hole face, its outer surface is protruding sphere, the part that contacts with bearing shell seat ring 2 on the cartridge housing frame 1 is a concave spherical surface, be to be the sphere sliding contact between bearing shell seat ring 2 and the cartridge housing frame 1, be evenly equipped with eight block sizes in the inner hole wall of bearing shell seat ring 2, the bar polymer graphite bearing shell 3 that shape is all identical, surface of contact between the adjacent bar polymer graphite bearing shell 3 is the plane, and constraint is supported mutually, their common looping bearing shells, the centre of bar polymer graphite bearing shell 3 has shaped like narrow through hole 4, the bearing shell seat ring 2 of following corresponding position is provided with oil groove 5, place the oil storage cup of eminence to be communicated with (oil storage cup by connecting tube and oil groove 5, connecting tube, do not draw among the figure), lubricant oil is through oil storage cup, connecting tube, oil groove 5, through hole 4 lubricated jack shafts on the macromolecule graphite bearing shell 3.Because macromolecule graphite lining material has good self-lubricating property, and can obtain lubricant oil from oil groove 6, thereby live axle can be in low speed or the state that runs up for a long time, and scuffing does not take place.The intermediate bearing of this structure has the self-aligning function.
Also be provided with water quench device and temperature sensor interface in the present embodiment, be respectively applied for the cooling and the thermometric (not drawing among water quench device and the temperature sensor interface figure) of bearing shell.
