| 摘 要： | 对航空螺旋锥齿轮断油工况进行分析,根据断油工况计算润滑油的初始啮合温度并建立螺旋锥齿轮断油润滑分析数学模型;通过编程得到断油情况下不同载荷、不同速度的接触区油膜厚度、压力和温度分布情况;分析油箱油量、断油时间、齿轮转速3个主要因素对断油润滑状态特别是中心油膜温度的影响。结果表明:航空螺旋锥齿轮在断油情况下,啮合产生的热量使油箱润滑油温度提高,在数值计算时需要对初始温度进行修正;随着油箱内润滑油量的增加,接触区润滑油温度降低;随着断油时间和齿轮转速的增加,润滑油温度逐渐升高,但升高速度逐渐减慢;齿轮转速和断油时间对接触区温度的影响大于润滑油量的影响。

| Abstract: | The oil-off work condition of aero spiral gears was analyzed.Based on the work condition the initial mesh temperature of the lubricating oil was figured out and the mathematical model of aero spiral gear under the oil-break off work condition was established.The thickness,pressure and temperature of the oil film under oil-break off work condition with different load and velocity were obtained by program.Through the computing of several samples,the influence of the three main factors,capacity of oil box,oil-... |
