项目摘要
Beveloid gears can be used with parallel, crossing and skewed axes. Industrial applications, especially in the automobile industry, use beveloid gears with crossing or skewed axes. Today, calculation methods of the tooth root carrying capacity of beveloid gears exist. The state of the art also includes calculation methods for the tooth root stress of beveloid gears with crossing or skewed axes. Up till today, no validated calculation method exists for the tooth root load carrying capacity of beveloid gears with crossing or skewed axes with consideration of the local material and strain properties, the gear flank geometry as well as the manufacturing deviations and tolerances. Therefore, the results of the preceding DFG-project "Development and Verification of a method for calculation the tooth root load carrying capacity of beveloid gears" should be transferred to an industrial application with crossing axes and made applicable for crossing and skewed axes. Thus, unused design potential for beveloid gears can be used in order to improve the operational behavior and reduce the manufacturing costs. Based on the local approach necessary tolerance fields for the gear geometry can be defined.The objective of the research project is to develop and apply a validated, industry applicable method for optimizing the gear geometry and manufacturing tolerances for beveloid gears with crossing axes in order to enhance the tooth root load carrying capacity. The method is able to predict the tooth root load carrying capacity with consideration of manufacturing deviations (twist). The result of the research project is a method which helps the design engineer in the gear industry to find the optimal gear geometry of beveloid gears regarding the tooth root load carrying capacity. The method should imply all the significant effects, e.g. manufacturing deviations, onto the tooth root load carrying capacity. Based on the method an optimization of the tooth root load carrying capacity with consideration of all manufacturing deviations is possible. The results of the local calculation approach and the experiments can be used to enhance the standard reference and therefore, improve the industrial design process and help finding the optimal gear design regarding the tooth root load carrying capacity. Thus, over-engineering and failed design regard the tooth root load carrying capacity can be avoided.
锥齿轮可用于平行轴、交叉轴和斜轴。在工业应用中,特别是在汽车工业中,使用具有交叉或偏斜轴线的斜齿轮。目前,存在计算锥齿轮齿根承载能力的方法。现有技术还包括具有交叉或偏斜轴线的变厚齿轮的齿根应力的计算方法。到目前为止,没有有效的计算方法存在的齿根承载能力的斜交或斜轴斜齿轮考虑当地的材料和应变特性,齿轮齿面几何形状以及制造偏差和公差。因此,先前DFG项目“计算锥齿轮齿根承载能力的方法的开发和验证”的结果应转移到具有交叉轴的工业应用中,并适用于交叉和斜轴。因此,可以使用用于斜齿轮的未使用的设计潜力,以便改善操作行为并降低制造成本。该研究项目的目的是开发和应用一种经过验证的、工业上适用的方法,用于优化具有交叉轴的斜齿轮的齿轮几何形状和制造公差,以提高齿根承载能力。该方法能够预测齿根承载能力与考虑制造偏差(扭曲)。本研究计画之结果,为齿轮工业中之设计工程师,提供一种依据齿根承载能力,找出最佳变厚齿轮几何形状之方法。该方法应包含对齿根承载能力的所有显著影响,例如制造偏差。基于该方法,考虑所有制造偏差的齿根承载能力的优化是可能的。局部计算方法和实验的结果可用于增强标准参考,从而改进工业设计过程,并帮助找到关于齿根承载能力的最佳齿轮设计。因此,可以避免过度工程和失败的设计方面的齿根承载能力。
