Abstract

The invention discloses a processing method for a textured surface of a gear, which relates to the field of gear friction and lubrication. A machining method for gear textured surface that can analyze and evaluate the contact and lubrication performance of gear textured surface completely, accurately and efficiently is proposed. The processing is carried out according to the following steps: S1, sampling; S2, data acquisition; S2.1, residual stress measurement; S2.2, three-dimensional shape measurement; S3, calculation; S4, evaluation; S5, processing. This method can reflect the proportion of various evaluation indicators in the comprehensive effect, and can accurately express the quantitative relationship between various evaluation indicators. Finally, the surface of the gear is processed according to the ideal gear texture surface in the subsequent processing, so as to effectively delay the oil film rupture during the use of the gear and prolong the actual service life of the gear.

Description

technical field [0001] The invention relates to the field of gear friction and lubrication, and mainly relates to a method for analyzing and evaluating the lubrication characteristics of a gear texture surface. Background technique [0002] During the gear transmission process, the failure of lubrication, that is, the rupture of the oil film will lead to direct contact with the gear surface, resulting in failures such as tooth surface wear and tooth surface gluing, and shorten the working life of the gear. Surface texture technology is obtained by processing micro-nano-level textures through surface processing methods such as laser processing, shot peening, electrical discharge processing, vibration turning, electrochemical processing, electron beam deformation, photolithography, reactive ion etching, and abrasive etching. The textured surface with certain micro-morphological characteristics can be used to enhance the sealing, enhance the bearing capacity of the surface oil ...
