Stresses in a bimetal strip of white metal bonded to steel, to simulate a journal bearing shell or a thrust bearing ring, have been calculated for various loading conditions. The stresses arose from: fluid pressure loading on the bearing surface whilst the back was supported on a complete rigid surface; locating and holding forces, e.g. compression due to nipping-up the bearing; elastic deformation of the bearing housing; differential thermal expansion and temperature gradients, and incomplete support of the bearing shell when subjected to fluid pressure on its bearing surface. Points at which fatigue damage is likely to originate are apparent. The stresses were calculated numerically from displacements which were found, by an iterative method, to satisfy a finite difference analogue of the governing differential equations.

In this paper thin-walled part deformation during finishing turning process caused by gripping force of hydraulic lathe chuck was investigated. Bearing ring was taken as an example of thin-walled part undergo finishing turning operation. Finite Element Method (FEM) was used to define the deformation of examined part. The aim of presented research was to compare the deformation of bearing ring caused by gripping force of hydraulic 3-jaw chuck and 6-jaw chuck for different values of total gripping force. The data obtained from conducted simulations allowed to evaluate the influence of gripping force on machining part deformation which is directly related with its geometrical accuracy.

The Impact

In this paper, six sigma methods were used in bearing ring grinding process improvement. In the improvement, bearing outer ring roundness error was selected as the assessment index, and exsiting problems in grinding process were defined, roundness error of bearing outer ring was measured.One-way analysis of variance was applied to analyze the test results, it indicates that workpiece center height, guide wheel tilt angle and grinding wheel balance are the three main factors that affecting roundness error.According to this analysis, orthogonal experiment was designed. The results show that grinding wheel balance, guide wheel tilt angle and workpiece center height on the impact of roundness error are in descending order. On this basis, a series of measures were carried out to control these three parameters. Uitimately, the grinding process capability index is increased from 0.88 to 1.43, and the target of improvement are achieved.
