Taking gear without tooth face invalidation such as agglutination and abrasion as a precondition, and according to the relation between minimal oil film thickness and tooth face roughness of elastic liquid dynamic pressure lubrication theory, viscosity of gear lubrication oil was educed by reliability method in this paper, and the calculation formula has been elicited and applied
摘要以齒輪傳動不發生膠合、磨損等齒面失效為前提，根據彈性流體動壓潤滑理論的最小油膜厚度與齒面粗糙度的關系，用可靠性方法確定齒輪潤滑油的粘度，給出計算公式並進行了實例計算。 -
The threshold speed and the typical characteristics of the oil whip of the system are simulated under the nonlinear model of oil film force, and the state of motion and type of the bifurcation are analyzed by floquet multiplicators which is computed by the shooting method. secondly, the the nonlinear dynamical model of the low - pressure rotor - bearing system by column bearing with reduced dimensions is presented. the numerical results show the rule of the amplitude with the eccentricity of rotor, the length - to - diameter ratio, oil viscosity and the clearance - to - radius ratio of the bearing under the definite speed
