基于对纳米ZrO_2、SiC、SiO_2、Al_2O_3的物化特性分析,探究含有纳米ZrO_2、SiC、SiO_2、Al_2O_3添加剂的润滑油对斜齿圆柱齿轮润滑的振动和噪声特性。对运行的20CrMnTi斜齿圆柱齿轮进行常规润滑油润滑和含纳米添加剂润滑油润滑试验,通过对斜齿圆柱齿轮施加不同的载荷和转速,分析不同工况和不同润滑方式下斜齿圆柱齿轮的振动及噪声特性,从试验的方面分析纳米添加剂润滑油对齿轮振动和噪声的影响。结果表明,纳米添加剂润滑油可在较短的时间内有效降低斜齿圆柱齿轮在不同工况下的振动及噪声值,特别是对于轴向的降振作用较径向的更加明显;同时,在此基础上进一步分析纳米添加剂润滑油润滑方式下,齿轮降振效果对载荷和转速的敏感性,发现纳米添加剂润滑油对齿轮的降振作用对转速更具敏感性。

Based on the analysis of the physicochemical characteristics of nano-ZrO2,SiC,SiO2,and Al2O3,the vibration and noise characteristics of lubricating oils containing ZrO2,SiC,SiO2,and Al2O3 additives on helical gears are investigated.The current 20CrMnTi helical spur gears are tested.Routine lubrication and lubricity with nano additive lubricants are applied.By applying different loads and speeds to helical gears,the vibration and noise characteristics of helical gears under different working conditions and different lubrication methods are analyzed.Effect of nano additive lubricant on gear vibration and noise is analyzed.The results show that the nano additive lubricant can effectively reduce the vibration and noise values of the helical gear under different working conditions in a relatively short period of time,especially for the axial vibration reduction effect is more obvious than the radial direction.On the basis of this,the sensitivity of the gear damping effect to the load and rotation speed under the lubricant additive method of nano additive is further analyzed,and it is found that the nano additive lubricant oil has more sensitivity to the rotation speed of the gear.
