摘　　要：针对现有双渐开线齿轮温度场计算模型不考虑油膜润滑影响的问题,根据双渐开线齿轮啮合特点,提出采用"分段法"建立适合双渐开线齿轮的热弹流润滑模型,综合有限元法和热弹流润滑方法对其本体温度进行研究,并以润滑油膜为热源对其瞬时温升进行研究,最后分析了齿腰分阶参数对双渐开线齿轮温度场影响以及与普通渐开线齿轮温度场差异.结果表明:双渐开线齿轮本体温度沿齿宽方向呈非对称分布,主动轮最高本体温度偏向齿根啮入端,从动轮偏向齿顶啮出端;啮合齿面间的油膜瞬时温升明显高于两齿轮界面温升,且主动轮界面瞬时温升高于从动轮;齿腰分阶参数变化对双渐开线齿轮温度场影响较小;双渐开线齿轮与普通渐开线齿轮的本体温度及齿面瞬时温升区别不大.In view of the problem that the ignorance on the influence of oil film lubrication for current calculation model of temperature field of double involute gears,based on the meshing characteristics of double involute gears,the TEHL model suitable for double involute gearswas established by adopting the idea of"subsection".A comprehensive finite element method and a TEHL method were used to study the bulk temperature,and the instantaneous temperature rise was studied by using the lubricating oil film as the heat source.Finally,the influence of the tooth waist order parameters on the temperature field of double involute gears and the difference from the temperature field of ordinary involute gears were analyzed.The results showed that the bulktemperature of double involute gearswas asymmetrically distributed along the tooth width,the highest bulk temperature of the driving gearwas inclined to the starting engagement at the tooth root,while the driving gearwas inclined to the ending engagementat tooth top.The instantaneous temperature rise of the oil film between the meshing tooth surfaces was significantly higher than that of the two gear interfaces,and the instantaneous temperature rise of the driving gear interface was higher than that of the driven gear.The change of the tooth waist order parameters had a minor effect on the temperature field of double involute gears.In addition,there was little difference between the bulk temperature and instantaneous temperature rise of double involute gears and ordinary involute gears.
