Abstract:During the process of high speed and heavy load,the high temperature and high contact stress generated in the gear friction interface are the major factors resulting in reduction of work efficiency,moving accuracy and the working life of gear drive mechanism.Surface texture can be applied to change the tribological properties of the friction interface of the gear pair,which offers a new way of friction reducing and antiwear for the gear.The main methods of friction reducing and antiwear on the gear surface of gear pair were introduced,and the feasibility of applying surface textured gear to antifriction was theoretically analyzed.The development and perspective of surface texturing technology in gear lubrication and improvement of interface tribological properties wee reviewed respectively.The problems in the friction reducing mechanism of gear surface texture,the research of characteristic parameters of surface texture and the design method of surface texture were analyzed.It is suggested that the following research should be focused on the mechanism of gear texture under extreme conditions,the relationship between characteristic parameters of gear texture and lubrication effects and the multivariate design method of surface texture gear.The significance and application prospect of the technology of gear surface texture to friction reducing on the gear surface were prospected.
