Abstract
This article takes the hydromechanics as a foundation, carries on the three dimensional model and grid division for the belt bearing with ear oil cavity by the GAMBIT software, and carries on the solution computation using the FLUENT software. Through this simulation software numerical, simulates the lubricant film pressure distribution, temperature distribution, supporting capacity condition and bearing rigidity of belt bearing with ear flow field under different parameters’ influence, and their changing rules and so on. As the oil contains air inevitably, and the presence of air affects the bearing characteristics ,so we study the effect of different parameters on oil film pressure distribution, gas distribution, the bearing capacity under gas model., their changing rules and so on as well. And carries on the quite comprehensive comparative analysis on this foundation, discusses the effect of the gap, the length to diameter ratio, entering oil pressure, eccentricity, rotational speed changes on bearing supporting capacity and lubricant film pressure. Meanwhile, carries on the comparative analysis of the different models, aiming to providing help for people to understand the influence of different parameter on bearing dynamic performance and providing reference for sliding bearing's optimization design and the shaping.
