Abstract

The gas-lubricated thrust bearing is widely used in agriculture mechanical systems, and the groove shape plays an important role on the hydrodynamic behavior of spiral-grooved thrust bearing (SGTB). Although the groove shape may change smaller, it is clear that the hydrodynamic response is very sensitive to the groove parameters. This paper proposes a computational method for the analysis of SGTB with gas lubricant, considering the effects of groove parameters. With the compressibility taken into account, the evaluation of lubrication performance for SGTB is obtained by the CFD technology. Also, the simulation results are compared with the published data, which indicates that the presented model of SGTB is able to obtain more realistic results of hydrodynamic characteristics of SGTB. Moreover, the mapping relationship between groove parameter and hydrodynamic behavior of SGTB is represented.

槽参数对气体润滑螺旋槽推力轴承流体力学性能的影响研究

气体润滑推力轴承在农业机械系统中有着广泛的应用，槽形对螺旋槽推力轴承的流体力学性能有着重要的影响。尽管凹槽形状可能变化较小，但很明显，流体动力学响应对凹槽参数非常敏感。本文提出了一种考虑槽参数影响的气体润滑SGTB的计算方法。在考虑压缩性的情况下，利用CFD技术对SGTB的润滑性能进行了评价。仿真结果与已发表的数据进行了比较，表明所提出的SGTB模型能够获得更真实的SGTB水动力特性结果。此外，还表示了槽参数与SGTB流体动力学行为之间的映射关系。

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
