... stiffness (TVMS) characteristics. Therefore, this article proposes a novel analytical model for the TVMS of helical gears that considers these factors. In this model, the thermal deformation of the gear foundation under a bulk temperature field is first determined using the displacement method. Blok's...

...Siyu Wang; Rupeng Zhu Based on “slice method,” the improved time-varying mesh stiffness (TVMS) calculation model of helical gear pair with tooth surface wear is proposed, in which the effect of friction force that obtained under mixed elastohydrodynamic lubrication (EHL) is considered in the model...

...Mingyong Liu; Yang Qu; Chenglong Hu; Enxi Deng The tribological properties of gear interface have been widely concerned in the past decades. In this study, based on the local involute profile and crown modification, a thermal elastohydrodynamic lubrication model is proposed for a helical gear pair...

... January 20, 2014. Assoc. Editor: Dong Zhu. 17 04 2013 16 11 2013 A thermal elastohydrodynamic lubrication (TEHL) finite line contact model is developed for a helical gear pair lubricated with an Eyring fluid or a power-law fluid in order to investigate the effects of the working...

...R. I. Raja Hamzah; Khamis R. Al-Balushi; D. Mba This paper presents experimental findings on the generation of acoustic emission (AE) from operational spur and helical gears as a function of specific film thickness ( λ ) . The latter was varied while the gears were operating by spraying liquid...
