Numerical Analysis of Hydrodynamic Lubrication on Water-lubricated Rubber Bearings
2015Co-Authors: You-qiang WangAbstract:friction coefficient. Abstract. Water lubricated rubber Bearings are one of the most appropriate Bearings for underwater use. The most popular design used widely today is the straight fluted rubber Bearing. The special configuration leads to partial hydrodynamic lubrication and low load capacity. A new Bearing Bush structure which is favorable for constructing continuous hydrodynamic lubrication was designed and produced for experiment in the paper. The eccentricity ratio of the new structure rubber Bearing was measured under different loads in experiment. Used the measured eccentricity ratios, the load capacity was calculated by numerical simulation and compared with the given test values. The calculated values were in good agreement with the given test results. The results show that complete hydrodynamic lubrication can be formed in the new designed rubber Bearing. The experimental results also indicate that there is an appropriate Bearing clearance which the load capacity is up to the maximum

Experimental and numerical study on water-lubricated rubber Bearings
Industrial Lubrication and Tribology, 2014Co-Authors: You-qiang Wang, Xiu-jiang Shi, Li-jing ZhangAbstract:Purpose – Water-lubricated rubber Bearing is one of the most appropriate Bearings for underwater use. The most popular design used widely today is the straight fluted rubber Bearing. The special configuration leads to partial hydrodynamic lubrication and low load capacity. A new Bearing Bush structure with two cavities which is favorable for constructing continuous hydrodynamic lubrication was designed and studied. The paper aims to discuss these issues. Design/methodology/approach – A new Bearing Bush structure with two cavities which is favorable for constructing continuous hydrodynamic lubrication was designed. The apparatus for studying the tribological behaviors of the two types of water-lubricated rubber Bearings has been devised and established in the paper. The experimental studies on the tribological properties of the rubber Bearings have been conducted under different loads and velocities. The eccentricity ratio of the new structure rubber Bearing with two cavities was measured in experiment and...

Optimization of a water cooled Submersible motor journal Bearing length using CFD
2014Co-Authors: A. Gundale, M. Ingale, Vidyadhar M. DAbstract:The journal in case of a water cooled Submersible motor is the Bearing surface of the rotor which consists of hard chromed stainless steel material. The Bearing consists of a Leaded bronze material (Bronze grade LTB 2,3 or 4 of IS 318 or Nitrile / cutless rubber) which is the softer part out these two. The failures of the Bearing Bush accounts for 90 % of the failures in a submersible motor. The implication of this failure is the complete breakdown of the Motor i.e. the windings will get damaged and expensive repairs would be required to be carried out. This clearly suggests that the design of such a journal should be properly investigated. A CFD approach would assist in establishing the dimension (length) of the Bearing. This paper presents step by step application of CFD to optimize the Bearing length and is an outcome of around 3 years of extensive research in an attempt to solve a manufacturer’s long standing problem.

A Simplified working procedure in designing the Bearing Bush for a 6" water-cooled submersible motor
International Journal of Engineering Trends and Technology, 2015Co-Authors: Patankar Rohit C, Mirza M.m, Gundale V.aAbstract:This paper presents a simple, working and verified design procedure for the Bearing Bush for a 6" water-cooled submersible motor. The paper shows the relation between eccentricity ratios, the limit for stable operation of a Bearing Bush system. Once the fluid film pressure is found out then load carrying capacity will have to be calculated. The power rating, speed, and weight of rotor must be known in order to estimate the torque and finally, we will get calculated diameter of the journal. From the electrical consideration, the paper shows how the useful torque and useful force can be referred in order to establish journal diameter. This simplified procedure presented in this paper will help the manufacturers in designing correct size of Bearing Bush for a specific motor. The resulting dimensions of Bearing Bush can be considered for the to generate a 3D cad model in order to conduct the FSI (Fluid Structure interaction) analysis.
