The Comparison of Straight Tooth Bevel Gear and Spiral Bevel Gear about the Stress of Gear Tooth
大型的数控龙门加工中心中,卧式主轴头通过一对直齿圆锥齿轮副来作为相交轴的传动部件。其加工中心在高速运转时,直齿圆锥齿轮副会发出大的噪声和冲击,导致加工中心的加工质量和精度下降。为了解决这一问题,提出采用弧齿圆锥轮副代替直齿圆锥齿轮副。基于ANSYS Workbench软件,分析直齿圆锥齿轮副与弧齿圆锥齿轮副的齿跟弯曲应力和齿面接触应力的状况,在此基础上,得出弧齿圆锥齿轮副在传动过程中其轮齿的综合力学性能要优越于直齿圆锥齿轮副相应的轮齿性能。这使得数控龙门加工中心可回转式卧式主轴头在更换前70分贝的噪声降至到60分贝,噪声得到了显著的降低。 In the large CNC gantry machining center, through a pair of straight bevel gear ...

Power losses in spiral bevel gears [PDF]
This dissertation describes a numerical modelling strategy for characterising the windage of a spiral bevel gear rotating within a static shroud. The techniques employed include the use of a parametric solid model, and flow field modelling using computational fluid dynamics (CFD) software.
