introduction：For grease，Especially the action mechanism of soap-based grease lubrication，Many scholars have done a lot of research work，however，There is no consensus yet，It needs to be solved by further research in the future。 Generally speaking，Most scholars believe that，Soap-based grease is a three-dimensional network structure system composed of metal soap and base oil sucked in the soap。Soap press-The oil gel particle dispersion concept can be considered，Soap based grease is a dispersing medium with oil and soap-The oil gel particles are a structural dispersion system of dispersed phase。therefore，The following views are obtained on the mechanism of grease lubrication。 It is commonly believed that，Due to metal soap
