- Abstract
Through the establishment of hot rolling model of spiral bevel gear, the numerical analysis of hot rolling process was carried out, the distribution characteristics of strain field during the process of hot rolling were studied and the influence mechanism of initial rolling temperature, addition of lubricant, gear blank rotational speed, mould feeding speed and other technical parameters on metal streamline was also explored. In addition, the rolling test on the spiral bevel pinion was carried out on the hot rolling test bed. The internal micro structures of the gear teeth and the morphological features of the metal streamlines after hot rolling were observed by an electron microscope. The research reveals that the surface layer of the metal streamline gear teeth obtained by hot rolling is almost parallel to the tooth profile, and the distribution state is beneficial to the improvement of bending fatigue and contact fatigue strength of spiral bevel gears.
