摘要

针对喷油润滑喷嘴无偏置和倾斜布置时,传动比大于1的齿轮传动润滑效果不良的问题,从齿轮啮合运转及喷油润滑的几何关系出发,采用解析法建立航空直齿轮啮出侧喷油润滑冲击深度计算数学模型;仿真验证数学模型的正确性,完成齿轮参数、传动参数和喷嘴位置等对直齿轮冲击深度的影响分析。研究表明,冲击深度随齿轮齿数和转速的增大而减小,随喷油速度的增大而增大;小齿轮冲击深度和大齿轮冲击深度随射流偏置和喷射倾角的变化呈负相关关系。研究结果可为喷油润滑设计提供理论依据。

Abstract

When the nozzle is decorated without offset and incline,gears with transmission ratios above 1 won’t be efficiently lubricated. In order to solve this problem,analytic method is adopted to establish mathematical model,basing on the geometric relationship between running gears and the jet flow. The mathematical model is used to calculate the impingement depth on aviation spur gears lubricated on the disengaging side. The correctness of the mathematical model is verified by simulation. The effects of gear parameters,transmission parameters and nozzle position on impingement depth of spur gear are analyzed. The results show that,the impingement depth decreases with the increasing of teeth number and rotating speed,while it increases with the increasing of jet velocity. The impingement depth on pinion is negatively correlated with that on gear as the change of jet flow offset and inclination angle. The research results provide theoretical bases for oil lubrication design.
