Parametric and controllable shape model of the water-lubricated rubber journal bearing Xiaoping Pang , Jin Chen, Jiaxu Wang, and Yi Hou The State Key Laboratory of Mechanical Transmission,Chongqing University, Chongqing, 400030, P.R.
The special bearing profile is decided by its material and work properties and has great advantages: It is easy to form water films because the transitions between water grooves and load curve are soft arc curves.
Here, the effects of the material and the multi-disciplinary coupling are ignored and the only thing to be done is to show the importance of the shape function.

Experimental The raw materials used in this study were the commercial pure aluminum (≥99.85%), magnesium ingots (≥99.75%), zinc ingots (≥99.75%), Al-20%Cu, Al-10%Mn and Al-5%Cr master alloy.

The method of finding the center of steam turbine shaft coupling based on multiple practice Jing Liu1, a, Yong-Sheng Kuang2,b 1Changsha university of science and technology, Energy and Power engineering national laboratory , Changsha, Hunan province, China. 2NingXiang town by the open area development road, Changsha, Hunan province，China.
Generally,according to the lack of a precise systematic, streamline processes, this process is time-consuming and waste of energy.This paper deduces the a simplified calculation method based on center adjustment, among them, clearly adjust center calculation is divided into several specific part, and clearly describe the key processes of it , and applied to other analogous process of finding center. 1 Center adjustment method of the application 1.1 Initial parameters In this example,the diameter of coupling of two rod plane table is referred to,which is D 603.00 mm, the distance of circular table to 2 # bearing center is 327.00 mm, center distance of2# bearing is 2220.00 mm,the angle of bearing adjustment block center and the shim the centerline named a=75 °, and cosa =0.28, sina= 0.92.Coupling circumference value and openings deviation as shown in Fig. 1, Fig. 1, Numerical coupling center before and after the adjustment 1.2 Calculation process and results Using formula
Each of the shim under the adjusting shim shoulds not be more than three pieces.To adjust gasket sheet steel should be adopted and phosphor copper, unfavorable use copper skin soft material such as Single chip thickness is not less than 0.02 mm, the aperture should be bigger than shim aperture of 1 ~ 2 mm; Gasket assembly, should be carefully cleaned its burring and rough edge.
