Calculation method of non-Hertz contact flash temperature of herringbone gear tooth under crossed axe malposition
摘要
Abstract
Aiming at the problems of uneven load distribution caused by crossed axe malposition and lack of effec-tive flash temperature calculation method in the anti-gluing design of herringbone gear,a discrete non-Hertz contact analysis method for herringbone gear under crossed axe malposition is proposed using the influence coefficient meth-od,considering effects of geometric transmission and crossed axe malposition errors on the initial contact gap.The contact stress of the 2D distribution and the contact half-width along the tooth width are obtained.Moreover,an im-proved Blok flash temperature formula is improved,establishing a dynamic calculation model of non-Hertz contact flash temperature of herringbone gear under crossed axe malposition.The accuracy of the proposed method is veri-fied by comparison.The results indicate that,with the increase in staggering angle,the unbalanced load on the left and right tooth surfaces increases gradually.With an increase in rolling angle,the flash temperature of the tooth surface and the temperature difference on both sides decrease first and then increase.As rotational speed increases,the flash temperature difference also increases,except at the node.The closer the location is to the meshing-in and meshing-out points,the faster the rate of increase.These findings provide a theoretical foundation for the anti-glu-ing design of herringbone gears.关键词
