【摘要】：随着科学技术的快速发展和市场竞争的日益激烈,企业的技术创新能力、新产品的开发能力和开发速度正成为企业核心竞争力的重要体现。低成本高效率地开发出新产品,成为赢得市场竞争的首要因素。本文针对中小民营企业技术开发力量不足的现状,以南通XX罗茨鼓风机有限公司新产品的开发为例,首先介绍了一种基于数控程序的产品反求设计方法。该方法分为：零件近似几何图形的获取、高次曲线的反求和优化设计三个阶段。在此基础上,以3L4系列罗茨风机转子反求设计为例,详细介绍了从数控程序到转子近似几何图形的获得、从圆弧拟合图形到真实渐开线方程的生成以及转子线型的最终优化设计,为中小企业反求设计提供技术指导和支持；其次,提出了一种基于均半径圆弧拟合和误差抵消的转子刨削加工方法。针对普通牛头刨床刀架系统刚性不足的问题,提出采用误差抵消的方法在数控程序中进行补偿。以3L5系列罗茨风机转子为例,详细介绍了均半径圆弧拟合转子渐开线的过程；在此基础上,对产生误差区域进行局部偏移进行二次修正,以保证转子最终加工精度；最后,开发了基于Solid works的罗茨风机参数化设计系统,以便中小企业能够进行系列化快速设计,满足客户的多样化和快速需求。
[Abstract]:With the rapid development of science and technology and the increasingly fierce market competition, the technological innovation ability, new product development ability and development speed of enterprises are becoming an important embodiment of the core competitiveness of enterprises. Low-cost and high-efficiency development of new products has become the first factor to win market competition. In view of the lack of technical development power in small and medium-sized private enterprises, taking the new product development of Nantong XX Roots Blower Co., Ltd as an example, this paper first introduces a reverse design method of product based on numerical control program. The method can be divided into three stages: obtaining approximate geometry of parts, reverse seeking of high order curve and optimizing design. On this basis, taking the rotor reverse design of 3L4 series Roots fan as an example, the acquisition of approximate geometry from numerical control program to rotor is introduced in detail. From the arc fitting figure to the generation of real involute equation and the final optimal design of rotor profile, it provides technical guidance and support for the reverse design of small and medium-sized enterprises. In this paper, a rotor planing method based on mean radius arc fitting and error canceling is proposed. Aiming at the shortage of rigidity of the tool holder system of ordinary oxhead planer, an error offset method is proposed to compensate in numerical control program. Taking the rotor of 3L5 series Roots fan as an example, the process of fitting the involute of rotor with mean radius arc is introduced in detail, on the basis of which, the local offset of producing error region is modified twice to ensure the final machining accuracy of rotor. A parameterized design system for Roots fan based on Solid works is developed so that SMEs can carry out serial and rapid design to meet the diverse and rapid needs of customers.
