【摘要】：平面二次包络环面蜗杆是传动领域中的一种重要的传动形式,其多齿啮合、瞬时多接触线的特性赋予了平面二次包络环面蜗杆承载能力大、传动效率高、加工工艺性好等优点。越来越多的学者和企业表现出对它的兴趣,也越来越广泛的应用于各行各业的生产实践中。平面二次包络环面蜗杆齿面复杂,齿形、齿厚的测量比较困难,传统的检测方法存在很多困难和缺陷。新型的检测技术还不成熟,有待进一步研究和发展。本文在对非接触式检测技术进行分析和研究的基础上,简要分析了采用面阵CCD对蜗杆进行非接触式检测方法的可行性和正确性,分析了平面二次包络环面蜗杆的成形原理,获得了蜗杆齿面方程,建立了蜗杆理论接触线的离散模型。结合图像处理、DSP、CCD等技术设计了检测系统的总体方案,阐述了系统检测原理与检测过程,并在前期理论研究的基础上对图像处理的算法等进行了分析与优化,对实验中CCD基准定位进行了理论分析与研究,完成了通过采用图像数字处理对CCD进行精确定位的方法,进行了实验研究和验证,并且将被测蜗杆与数控磨床进行联动检测,对所采集的图像进行数字分析并得出相关误差。
[Abstract]:Two plane enveloping worm is an important transmission form in the field of transmission, the multi tooth meshing characteristics, instantaneous contact line with two planar enveloping worm bearing capacity, high transmission efficiency, has the advantages of good processing technology. More and more scholars and enterprises showed interest in it also, the production practice is more and more widely used in all walks of life.
Planar two enveloping hourglass worm faces are complex, and the measurement of tooth profile and tooth thickness is rather difficult. The traditional detection methods have many difficulties and defects. The new detection technology is not yet mature, and needs further research and development.
Based on the analysis and research of non-contact detection technology, a brief analysis of the feasibility of using array CCD non-contact detection method of worm and correct, analyzed the forming principle of two plane enveloping worm, the worm tooth surface equation, a discrete model of worm theory of contact line the combination of image processing, DSP, CCD and other technical design the overall scheme of the detection system, describes the system test principle and test process, analysis and optimization of image processing algorithm based on the preliminary research, the experiment of CCD positioning are analyzed and the research theory, completed by using digital image processing method for precise positioning of CCD, was investigated and verified, and will be measured and worm CNC grinder for linkage detection in the image digital The relative error is obtained.
