Description
Technical field
The utility model relates to the middle shaft transmission device of marine propuision system, in particular for the intermediate bearing of supporting 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.In addition, design now and the boats and ships of building, it is that technology is carried out in the reasonable school that axle is adopted in the installation of axle system basically, each supporting point of axle system is placed stressed optimum position, this just requires axle system to install according to the reasonable stress curve of computational rules, so that axle is each bearing load reasonable distribution, reducing axle is loss, increases the service life, and the inevitable requirement intermediate bearing has the ability of aligning voluntarily like this, be that supporting surface is on the theoretical centerline all the time, also have hull after navigation a period of time, since the deformation of hull, reasons such as bearing wear, feasible axle is that variation has taken place state in the former school, and this also requires intermediate bearing can have to a certain degree compensate function.
At present, the common structure that is used to support the intermediate bearing of jack shaft in China's shipbuilding industry is opposite opened intermediate bearing or sliding type intermediate bearing, Chinese patent ZL200520112789.6 discloses a kind of rolling intermediate shaft bearing, and this intermediate bearing in use exists following deficiency: the one, and no follow-up adjustment between the bearing housing of intermediate bearing and the bearing; The 2nd, in the roller type intermediate bearing, roller is the line contact with contacting of Internal and external cycle, and this makes that the bearing capacity of intermediate bearing can not be very high; The 3rd, because lubrication system is relevant with the rotating speed of transmission shaft, thereby transmission shaft is when being in low speed state, and the greasy property of bearing shell is bad, even appearance " Bearing score " phenomenon; The 4th, though there is one deck Babbitt (claiming white metal again) on the surface of bearing shell, its wear-resisting property still can not satisfy the large-diameter transmission shaft and work long hours.
The model utility content
In order to solve the above-mentioned deficiency of prior art, technical problem to be solved in the utility model provides a kind of sphere from the big specific pressure intermediate bearing of aligning, it can effectively improve the bearing capacity of intermediate bearing, has certain ability of aligning voluntarily and good lubricating property again.
At above-mentioned technical problem, the scheme of the utility model technical solution problem is: a kind of sphere is from the big specific pressure intermediate bearing of aligning, comprise the divided bearing involucrum and be fixedly mounted on this bearing involucrum inside and supporting surface is the split-type shaft bearing of interior concave spherical surface, be placed with the split bushing that outer surface is the evagination sphere on the concave sphere supporting surface of described bearing support, the inwall of this bearing shell is provided with macromolecule graphite liner and the Babbitt liner that distributes alternately.
Owing to adopt technique scheme, contact for sphere between bearing shell and the bearing support, increased area of contact, improved the bearing capacity of intermediate bearing from the bearing structure greatly, and the inwall of bearing shell is provided with Babbitt liner and the macromolecule graphite liner that distributes alternately, macromolecule graphite lining strength, wear-resisting property, resistance to high temperature and self-lubricating property all are better than Babbitt, improve the mechanical strength of bearing shell, high temperature resistant, wear-resistant and self-lubricating property from material, compensated the deficiency of single Babbitt liner.Change the ratio of macromolecule graphite liner inner wall area and Babbitt liner inner wall area when manufacturing and designing, can change the bearing capacity of intermediate bearing,, avoid cost high, improve the product competition advantage to adapt to the performance need of various intermediate bearings.On the other hand since between bearing shell and the bearing support for sphere contact, form spherical bearing, thereby bearing shell can swing flexibly in the bearing support certain limit, the trace variation of center line when moving to adapt to axle system.Comprehensive above-mentioned three aspects, it is big that a kind of sphere of this model utility can support the diameter of axle from the big specific pressure intermediate bearing of aligning, the transmission shaft that axle body is heavy, and stable operation for a long time.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model sphere is described in further detail from the big specific pressure intermediate bearing of aligning.
Fig. 1 is the structural front view of the utility model sphere from a kind of embodiment of the big specific pressure intermediate bearing of aligning.
Fig. 2 is the left view of structure shown in Figure 1.
Embodiment
In Fig. 1, Fig. 2, it is split-type shaft bearing 2-1, the 2-2 of interior concave spherical surface that supporting surface is installed in the divided bearing involucrum 1, be placed with split bushing 3-1,3-2 on the supporting surface of bearing support 2-1,2-2, the one side that bearing shell 3-1,3-2 contact with bearing support 2-1,2-2 is the sphere of evagination, and and the supporting surface of bearing support 2-1,2-2 fit and sliding contact i.e. sphere contact.Distributed alternately on the inwall of bearing shell 3-1,3-2 Babbitt liner 4-1 and macromolecule graphite liner 4-2, wherein the quantity of macromolecule graphite liner 4-2 is 4, by screw and be evenly distributed on the inwall of bearing shell 3-1,3-2.The axle supporting surface that the inwall of the inwall of Babbitt liner 4-1 and macromolecule graphite liner 4-2 fences up and forms a cylindrical shape.Leave gap 5 between adjacent macromolecule graphite liner 4-2 and the Babbitt liner 4-1, be positioned at following bearing shell 3-2 and be provided with oil groove 6, be positioned at following bearing support 2-2 and be provided with oil groove 8, place the oil storage cup of eminence to be communicated with (oil storage cup, connecting tube, figure do not draw) by connecting tube and oil groove 6, oil groove 8, lubricant oil is through oil storage cup, connecting tube, oil groove 6, gap 5 lubricated jack shafts.Because macromolecule graphite lining material has excellent mechanical intensity, abrasion resistance properties, heat resistance, and self-lubricating property, on bearing structure, can from oil groove 6, obtain lubricant oil again, thereby intermediate bearing can support the jack shaft of the big quality of large-diameter, and the lubricating condition when improving the jack shaft low-speed running, effectively prevent " Bearing score " phenomenon.
Also be provided with water quench device and temperature sensor interface in the present embodiment, be respectively applied for the cooling and the thermometric of bearing shell.Do not draw among water quench device and the temperature sensor interface figure.
