三阶非圆齿轮泵的流量脉动及可滚齿性研究
|
摘要
随着齿轮泵向高压大流量低噪声方向发展,提出了一种低困油、少脉动的非圆齿轮泵,并建立相应的节曲线模型。通过2个三阶椭圆齿轮作为工作齿轮的情形(称为3-3组合)、3个三阶椭圆齿轮作为工作齿轮的情形(称为3-3-3组合)在流量和流量脉动率方面的对比,确定3-3-3组合作为非圆齿轮泵的主要结构。非圆齿轮轮齿都有特定的啮合位置,利用坐标变换法分析了非圆齿轮的齿廓方程,为CAD建模和仿真分析提供了理论依据。用图形形式直观地反映出不同阶数非圆齿轮的凸性判别,得到三阶非圆齿轮能用滚齿法加工的条件,为非圆齿轮的加工工艺路线明确了方向。
With the development of gear pumps towards the direction of high pressure,high flow,and low noise,the paper presents a kind of non-circular gear pumps with low trapped oil and pulsation,and establishes the corresponding pitch-curve mode.By contrasting 3-3combination with 3-3-3combination in terms of flow and flow pulsation rate,the 3-3-3combination is used as the main structure of non-circular gear pump.Coordinate transformation method is used to analyze the non-circular gear tooth profile equation,which provides a theoretical basis for establishing CAD modeling and simulation analysis.A graph is used to directly reflect the different order number convexity judging of non-circular gear,and obtain the conditions for the processing of three-order non-circular gears through the gear hobbing method,thus pointing out the direction for the technical route of non-circular gear processing.
