中文摘要：

齿轮齿条在现代机械中应用广泛,但传动过程中易产生噪声、磨损、齿面胶合等,通过对机构润滑理论的研究,降低传动过程中齿面磨损及胶合机率。在现有的弹性流体动力润滑理论的基础上,利用多重网格法,得到了齿轮齿条传动过程中等温稳态弹流润滑数值解,讨论了齿轮齿条传动机构在不同啮合点、变位系数、线角传动比和模数下的无量纲压力和膜厚图,计算结果表明：啮合点位置、变位系数、线角传动比、模数等都会对油膜压力与膜厚产生影响。最终得出结论：在传动过程中,啮入点为啮合过程中的危险点;正变位能够使油膜变厚,负变位使油膜变薄;线角传动比、模数越大,油膜压力越小、膜厚越厚。

英文摘要：

The Gear rack is widely used in modern machinery,but it is easy to produce noise,wear and tooth surface scoring etc during the transmission process. Through research of the theory of mechanism lubrication to reduce the probability of tooth wear and tooth scoring during the transmission process. On the basis of the existing EHL theory,the EHL numerical solution of gear rack is obtained by utilizing the multi- grid method and the distribution of dimensionless pressure and film thickness under the effect of different mesh point,different modification coefficient,different ratio of line to angel and different modulus of the gear rack transmission mechanism are discussed. The results show that the position of mesh point,modification coefficient,ratio of line to angle and modulus are all have impacts on the oil pressure and film thickness. Eventually come to the conclusion that the meshing point is the dangerous point during the transmission process,the positive shift makes the oil film thicker while the negative shift makes the oil film thinner,the more ratio of line to angle and modulus,the smaller pressure and the thicker the film thickness.
