考虑可生产性的情况下,开发一种面向通用功能的方法来设计斜角的侧面修正

基本信息

项目摘要

A particular gear type which becomes more and more important is the beveloid gear, also known as conical involute gear. This is manly due to their ability to realize small crossing angles between shafts and they can be produced economically on conventional gear grinding machines. Beveloid gears have been used in marine applications, for example, for many years. In recent years the use of beveloid gears in the automotive sector has increased. Here the beveloid gear is used, for example in four wheel drives to transmit torque and rotation from the output of the gearbox to a front axle that may not be parallel.The running behavior of gears is generally characterized by load carrying capacity and noise vibration harshness (NVH). Conventional flank modifications, like crownings and angle modifications, can be used to optimize the running behavior. For beveloid gears this optimization reaches its limits. Due to the geometry and positioning of beveloid gears it is not possible to realize full line contact instead of point contact by using standard modifications. Line contact leads to a better load distribution on the tooth flanks which leads to decreased Hertzian stresses. In existing designs for realizing line contact the machinability of the flank modifications is not regarded. Furthermore there exist no methods to measure and tolerate these topological modifications.For spur and helical gears exist methods to manufacture topological flank modifications. But the process stability and profitability of this manufacturing method is low. Thus standard manufacturing processes like the continuous generating grinding are preferred to match economical and technical requirements. Additionally there exists no function oriented method to tolerate topological flank modifications. Ergo the full potential of topological flank modifications is not completely utilized.Hence, regarding the actual state of the art, the aim of this research project is to develop and verify a general function oriented method to design flank modifications of beveloids under consideration of producibility. The definition of existing flank modifications is extended in that way that topological modifications are defined locally for each point of the flank. The purpose of this method is the optimization of the beveloid gears running behavior (load carrying capacity and NVH), regarding the constraints of standard manufacturing processes.
一种特殊的齿轮类型,它变得越来越重要是锥面齿轮,也被称为圆锥渐开线齿轮。这主要是由于它们能够实现轴之间的小交叉角,并且它们可以在传统的齿轮磨床上经济地生产。例如,斜面齿轮已在船舶应用中使用多年。近年来,锥面齿轮在汽车行业的使用有所增加。在这里,斜面齿轮被使用,例如在四轮驱动中,从变速箱的输出传递扭矩和旋转到可能不平行的前桥。齿轮的运行特性通常由承载能力和噪声振动粗糙度(NVH)来表征。传统的侧面修改,如冠形和角度修改,可以用来优化运行行为。对于锥面齿轮,这种优化达到了极限。由于锥面齿轮的几何和定位,它是不可能实现全线接触,而不是使用标准修改点接触。线接触导致齿侧更好的载荷分布,从而降低赫兹应力。在现有的实现线接触的设计中,没有考虑到侧面修正的可加工性。此外,没有方法来测量和容忍这些拓扑变化。对于正齿轮和斜齿轮,存在制造拓扑齿面修形的方法。但这种制造方法的工艺稳定性和盈利能力较低。因此,为了符合经济和技术要求,首选标准制造工艺,如连续磨削。此外,不存在面向功能的方法来容忍拓扑侧翼的修改。因此,拓扑侧翼修饰的全部潜力没有得到充分利用。因此,考虑到目前的技术状况,本研究项目的目的是在考虑可生产性的情况下,开发和验证一种通用的面向功能的方法来设计斜面曲面的侧面修改。对现有翼面修改的定义进行了扩展,对翼面各点局部定义拓扑修改。该方法的目的是优化锥面齿轮运行行为(承载能力和NVH),考虑到标准制造工艺的约束。
