Abstract：
In order to improve the carrying capacity and the stability, a new structure of journal bearing with deep transition cavity is put forward. By using differential method with fractionized grid considering the boundary condition of the bearing, the characteristic analysis and optimization design are carried out. Serial characteristic data and structure parameters of the bearing are obtained. The bearing is provided with the performance of large load capacity and high stability. Comparing with general journal bearing, the load capacity of the new bearing can be increased by 18%-98%, the attitude angle is decreased from 43° to 14° and the stable rotate speed can be increased by 10%-75% under general work condition. The pressure distribution and eccentricity ratio of the bearing is measured on the HZS-1 bearing test-bed. Experiment results is well coincided with theory results.
