According to design method of the present invention, the strip type water lubricating rubber stern bearing to traditional is axially being carried out to hardness subregion.Fig. 1 is traditional strip type water lubricating rubber stern bearing schematic diagram, and Fig. 2 is a kind of water lubricating rubber stern bearing schematic diagram carrying out after hardness subregion in the embodiment of the present invention.
Water lubricating rubber stern bearing is made up of stern bearing lining 1 and rubber bearing bush 2.Be different from other bearing, water lubricating rubber stern bearing normal length is longer, contacts and bear pressure with shaft part.Due to the cantilever action of propeller cavitation gravity, the pressure distribution of rubber bush bearing has edge effect, reaches maximum near stern end contact pressure, and distortion is also maximum, and successively decreases gradually to head end from maximum value, presents uneven distribution feature.The distinctive uneven distribution of this long stern bearing is for the working life of stern bearing, and contact performance has a great impact.Conventionally under situation, whole stern bearing rubber adopts a monodrome hardness, consider the uneven distribution characteristic of pressure, we creatively propose, according to its Pressure Distribution, the rubber bearing bush of whole long stern bearing 2 is divided into several regions that hardness is different, to adapt to actual loading, improve the contact performance of bearing.
The impact of the research in comprehensive early stage and processing, technique, cost, in the time that stern bearing is carried out to hardness zoning design, number of partitions and hardness value can be with reference to following schemes:
In reference scheme, partition length ratio and hardness value are determined in main consideration hardness subregion effect and the control of stern bearing integral rigidity.As hardness being divided into three regions, according to author's early-stage Study, get region one rubber hardness minimum, region three rubber hardness maximums (value while conventionally adopting unified hardness).Each region length is vertically also different, for controlling the integral rigidity of stern bearing, makes region three length maximums, and the overall length in restricted area one, region two is less than the half of bearing overall length.Normally, in the time that each region is divided, should guarantee the length maximum near the region of head end, for example, exceed the half of total length.
Correspondingly, the present invention also provides according to the water lubricating rubber stern bearing of said method design, described in it, the rubber bearing bush of water lubricating rubber stern bearing is divided into multiple regions from stern end vertically to head end, the rubber hardness of the regional from stern end to head end increases successively, and the length maximum in the region of close head end.This water lubricating rubber stern bearing adapts to actual loading, improves the contact performance of bearing.
The hardness subregion of this water lubricating rubber stern bearing can design according to the method described above.

4 result of calculation comparative analyses
Axle system-stern bearing system to original design and after improving is carried out FEM (finite element) calculation respectively, has contrasted bottom rubber bearing bush pressure stress, rubber bearing bush contact, the vertical distortion of stern tube shaft and the rubber bearing bush axial deformation of two models.
1) bottom rubber bearing bush contact pressure stress
Because axle is self structure, stern bearing pressure is very large, and the distribution of the compressive stress of rubber bearing bush is directly connected to the properties of axle system.In each rubber bearing bush, bottom bearing shell stressing conditions is the most severe.Extract the pressure stress of bottom bearing shell, and improvement project and original design are contrasted, as shown in Figure 8.
In original design, from stern end face, in the length of 0～0.07m, pressure stress rises to 1.68MPa from 0.15MPa vertically, then reduces gradually, is reduced to 0.017MPa to bow end face.
In improvement project, bearing shell maximum crushing stress appears at apart from stern end face 0.23m place, and maximum value is 1.25MPa.In the length of 0～0.07m, pressure stress rises to 1.21MPa from 0.099MPa.Between 0.07m～0.42m, pressure stress fluctuates between 1.05MPa～1.25MPa, and due to the change of rubber hardness, distribution of the compressive stress has produced three crests.From 0.42m to bow end face, pressure stress is decreased to 0.02MPa gradually.
Contrast is found, from stern end face, in the scope of 0.39m vertically, in improvement project, stern bearing stress is less than original design, maximum difference be 0.47MPa. from 0.39m to bow end face, in improvement project, stern bearing stress is greater than original design, maximum difference is 0.2MPa.Compared with original design, the maximum stress of improvement project has reduced 0.43MPa, has reduced 25.6% with respect to original design.Meanwhile, between 0.07m～0.42m, in improvement project, pressure stress maximum difference is 0.2MPa everywhere, and in original design, maximum difference is 0.46MPa, and the distribution of the compressive stress of improvement project is more even.Data show that improvement project obviously improved the distribution of the compressive stress situation of water lubricating rubber stern bearing.
2) the circumferential distribution curve of bearing shell contact
The total some slat gum bearing shells of stern bearing that the embodiment of the present invention is analyzed, its sectional shape as shown in Figure 1.Due to along circumferential present position difference, apart from the same distance of stern end face, each bearing shell pressure also has larger difference.As shown in Figure 5, apart from stern end face 0.23m place, the bearing shell pressure stress of improvement project reaches maximum value.Extract all bearing shells at the Surface Contact pressure apart from stern end face 0.23m place, take the center of bottom bearing shell as initial point, each bearing shell contact is depicted as to curve, as shown in Figure 6.
In original design and improvement project, stern end contact pressure is along circumferentially distribution trend is more consistent.Bottom bearing shell pressure maximum, and successively decrease gradually to both sides.Due to the impact of tank, the contactless pressure in tank position.
Compared with original design, apart from stern end face 0.23m place, improvement project contact maximum value is 1.29MPa, is less than the maximum value 1.43MPa of original design.
In original design, the contact of rubber bearing bush stern end face is mainly distributed within the scope of circumferentially-43.6o～43.6o.In improvement project, contact is mainly distributed within the scope of circumferentially-46.5o～46.5o, and compared to original design, stern end contact region is along circumferentially having increased 5.8o.The increase of contact area, is conducive to reduce the specific pressure of stern bearing.
3) the vertical distortion of stern tube shaft
The stern bearing rubber hardness improvement project that the present invention proposes, has reduced the rubber hardness of rubber bearing bush regional area, and stern bearing rigidity is had to certain influence.The distortion that reduces to increase stern tube shaft of stern bearing rigidity, affects the performance that axle is.Extract the vertical deviation of stern tube shaft, curve plotting, as shown in Figure 7.
In original design and improvement project, the vertical deformation tendency of stern tube shaft is basically identical.Due to the cantilever action of propeller cavitation, axle is that stern end is sagging, deformation values maximum.Due to the supporting effect of stern bearing, middle stern bearing, there is upper arch in stern tube shaft middle part.Stern bearing place in the middle of approaching, stern tube shaft is without vertical distortion.
In original design, the maximum sag of chain of stern tube shaft stern end is 0.93mm, and maximum arch value is 0.145mm.According to each point slope on stern tube shaft vertical deviation curve, obtain stern tube shaft hard-over 0.000608o, much smaller than " CB/2338-2005 "
[11]the 0.02o of middle requirement.
In improvement project, the maximum sag of chain of stern tube shaft stern end is 1.08mm, and maximum arch value is 0.192m.Stern tube shaft hard-over 0.00069o, has increased 0.000082o than original design, still much smaller than " CB/Z338-2005 " the middle 0.02o requiring.
4) rubber bearing bush compressive deformation
Stern bearing rubber bearing bush bar is under Action of Gravity Field at propeller cavitation and axle, produces extrusion-deformation, chooses the most violent bottom bearing shell of compressive deformation, draws the axial displacement curve after its compressive deformation, as shown in Figure 8.
In original design and improvement project, bottom bearing shell axial deformation trend is basically identical.The distortion of stern end face axial is maximum, is reducing rapidly vertically within the scope of about 0.07m.Because improvement project has reduced the hardness of rubber bearing bush part area, rubber bearing bush maximum axial displacement is increased to 1.14mm by the 0.9mm of original design.Meanwhile, each region intersection in improvement project, because rubber hardness changes, causes axial displacement to increase herein, is about 0.02mm.
From above-mentioned practical application, can see, apply hardness partition type design method provided by the present invention, guarantee under the prerequisite that stern bearing rigidity is enough, can improve well the contact performance of stern bearing, meanwhile, also also uncomplicated in processing technology, be simple and easy to realize.In addition, the present invention has good ductility, can be according to practical situations, and zoning flexibly, arranges hardness, thereby reaches the object of optimization, with a wide range of applications.
