In order to master the abrasion properties of composite sliding guideways of gear hobbing machines,based on the principle of crawl of vibration theory,Reynolds theory,and the working condition parameter of composite sliding guideway,a model of the stable attrition phase was established to calculate the attrition depth of changing with time,the experimental project for test the attrition depth of composite sliding guideway of the gear hobbing machine was proposed,and the corresponding experimental apparatus were developed successfully. The attrition depth were tested with the sample parts of composite sliding guideway of gear hobbing machine,the theoretical calculations were compared with the experimental values. It is shown that the relative error of the results is lower than 5%. The above analyses indicate the effectiveness and validity of the proposed method,which has beneficial reference value and instructive significance for optimum oil groove structure,geometry parameter,and oil film load-bearing capacity design,and type selection of composite sliding guideways on gear hobbing machines.
