In order to enhance the load carrying capacity of oil film,improve lubrication effect and the tribological performance of textured surface,the lubrication performance of reticular texture under the lubricating oils with different viscosity were studied.Four kinds of reticular textures with different groove widths were designed.By measuring the contact angle,oil film load capacity and friction coefficient,the change rules of the oil film load capacity and friction coefficient of four kinds of reticular textures under the lubricating oil with different speed and different viscosity were obtained.The experimental results show that among the four textures,the reticular texture with groove width of 0.4 mm presents the best lubrication performance,the maximum oil film load carrying capacity is 0.52 N and the minimum friction coefficient is 0.019 under the set experimental conditions.In addition,the contact angle measurement results show that the reticular texture surface with groove width of 0.4 mm has the best hydrophobic performance and film forming ability,the dynamic pressure load capacity on the texture surface is improved,and the friction coefficient is also much smaller.By comparing lubrication performances of reticular texture surfaces lubricating oils with different viscosity under different speed,the higher the viscosity is,the greater the oil film load capacity is,which might be conductive to excellent lubrication.At the same time,the oil film load capacity increases with the increase of the speed,which is more significant when the lubricating oil viscosity is higher.
