摘要
随着机械设备日益重载化、高速化,给滑动轴承承载性能提出更高要求。通过使用FLUENT软件,构建轴承油膜润滑模型,并选定适合的参数进行计算,主要探究油膜厚度、油槽位置以及瓦块倾角不同时滑动轴承承载力的变化情况,找出内在规律。研究结果显示,油膜越小,轴承承载力越大;膜厚固定时,随着轴瓦倾角的增大,轴承承载力会先增大后减小;油槽位置外移程度越大,则轴承承载力提升越明显。
With the increasingly heavy load and high speed of mechanical equipment, higher requirements on the bearing capacity of sliding bearings are put forward. The oil film lubrication model of the bearing is built by using the FLUENT software, and suitable parameters are selected for calculation. The changes of bearing capacity of sliding bearing with different oil film thickness, oil groove position and tile inclination angle are studied mainly, and the internal laws are found out. Results show that the smaller the oil film is, the greater the bearing capacity;if the film thickness is fixed, the bearing capacity will first increase and then decrease with the increase of the inclination angle of the bearing bush;the further the oil groove moves outward, the more obvious the bearing capacity will become.
