This paper is mainly devoted to: (1) the description of the special features of the equations of pressure, equations of flow and resistance and the calculations of the performances of the journal bearings under turbulent conditions; (2) the comparison between the performances of the elliptic bearings under turbulent conditions and those under laminar conditions. The comparison shows that with the same eccentricity the load capacities for the turbulent operation are larger, the stiffness and damping of the oil film are greater and stability conditions are basically the same. With the same coefficients of load capacities, the oil flow for the turbulent operation will be a little greater or smaller, the power losses and temperature rises will be about thrice larger and the regions of stability will be slightly narrower. Thus the data for laminar operation may be used to estimate the stability performances for turbulent operation in case of lack of the turbulent data; (3) a comparison among several theories of the turbulent lubrication developed abroad more recently by Constantinescu, Ng and Pan, Aoki and Harada and Hirs. These theories have been examined and analysed. The result shows that the theory put forward by Aoki and Harada is the best of all. On the other hand the Hirs Theory is obviously unreasonable when it is used with large eccentricities; (4) suggestions and recommendations made to the manufacturer concerned: recommending the length diameter ratio should be chosen as 0.75, the elliptic ratios should be chosen between 0.5 and 2/3 and some kinds of grooves for oil outflow should be made in the region of the oil film rupture to reduce power losses; (5) a preliminary disoussion on the rational criteria for determining the flow regime in the oil film of an elliptio bearing. The materials in the paper may prove helpful in designing, calculating and experimenting with bearings for turbulent operation.

本文主要介绍:(1)紊流工况下椭圆轴承的方程(雷诺、流量和阻力方程),计算框图以及计算中的几点考虑:紊流系数的选取;油膜破裂区阻力的考虑;紊流系数中的局部雷诺数R_h值;紊流流道中出现层流段的考虑等。(2)紊流工况和层流工况轴承性能差异分析。(3)紊流工况椭圆轴承的性能曲线和分析。(4)对某机组用椭圆轴承结构、参数的建议。

The static and dynamic characteristics as well as the stability data of elliptical bearings are presented in considerable detail. The influence of main design parameters of the bearing such as clearance ratio, ellipticity and length diameter ratio on bearing characteristics and stability are analyzed and discussed. Some recommendations for the selection of these parameters are contributed.
