摘要
为研究过盈装配对圆弧齿轮加工的影响,文中建立了圆弧齿轮端面坐标的数学模型.通过圆弧齿形的端面坐标,获得圆弧齿轮螺旋面方程,并以此为基础,分析齿轮与轴过盈配合所产生的接触应力和接触变形,求解出接触面允许的最大过盈量和最大接触应力.通过齿轮的变形,研究过盈配合对圆弧齿轮加工的影响.通过模拟球头铣刀加工圆弧齿形的过程,分析过盈变形对齿形加工的影响,对今后圆弧齿轮的加工以及过盈量的选择提供理论支持.
In order to study the effect of interference fit on circular arc gear machining,a mathematical model of circular arc tooth profile was established based on the end face coordinates of circular arc gear.Also,the helical surface equation was obtained according to the end face coordinates.Based on the circular arc gear model,the stress and deformation of interference surface between gear and shaft were analyzed,and the allowable maximum deformation and contact stress of the interface were solved.The effect of interference fit on the machining process was studied based on the deformation of tooth profile.The machining process of circular arc profile by bulb milling cutter was simulated,and the influence of deformation on the machining of tooth profile was analyzed.The results show that,the calculation and analysis methods can provide a theoretical support for the machining and selection of the interference fit between gear and shaft.
