考虑油膜动态承压与表面粗糙度的齿轮传动效率特性
Gear Transmission Efficiency Characteristics Considering Oil Film Dynamic Pressure and Surface Roughness
摘要
Abstract
Gear transmission efficiency is an important parameter to measure the mechanical transmission system performance,which is affected by the lubricating oil,structural characteristics and operating conditions.Considering the dynamic pressure-bearing of oil film and surface roughness,the load ratio function is introduced and the cylindrical gear prediction model of friction resistance loss is established based on the principle of minimum potential energy.The dynamic and static characteristics of transmission efficiency influenced by oil characteristics,load conditions and surface roughness are quantitatively analyzed.And the influence of technical state deterioration on transmission efficiency under multi-factor coupling are analyzed.The results show that the dynamic transmission efficiency in the junction area between roping in-out and single-double tooth meshing is greatly affected by the oil properties.The load torque and speed have the greatest adverse effect on average transmission efficiency,followed by the surface roughness and oil temperature.Multi-factor coupling deterioration worsens power transmission effectiveness.Different types of deterioration have different effects on transmission efficiency,which can be used as the basis for the analysis and identification of gear transmission performance deterioration.关键词
