【摘要】 近年来，随着加工制造、工艺、材料冶炼及热处理等技术的进步和迅速发展，作为精密线性传动的首选部件之一的滚珠丝杠副越来越受到国内、国际制造业的重视，其综合性能也有了很大的提高，因此本文在此基础上对滚珠丝杠副额定动载荷加以探讨和研究。 本文的工作可以概括为以下几个方面： 第一章，回顾了滚珠丝杠副的发展简史，概述了其国内、外的发展现状及动态，总结了一些滚珠丝杠副的国内外研究成果，然后提出了课题的研究背景、意义及可行性，最后对本文所研究的内容、期望达到的目标作了阐述，并概括了本文的总体框架。 第二章，首先说明了滚珠丝杠副额定动载荷的理论来源和计算公式，之后对影响滚珠丝杠副额定动载荷的几何制造尺寸，如滚动体直径、导程等及材料因素作了分析。 第三章，本章首先对滚珠丝杠副额定动载荷计算值的材料影响因素进行了分析，之后结合原计算公式对额定动载荷计算的简化提出了滚珠丝杠副额定动载荷的计算修正公式。最后将修正公式的计算数据与某企业样本值及新计算值相对比说明了修正公式的优越性。 第四章，滚珠丝杠副设计计算、校核及选型系统是一个综合运用滚珠丝杠副设计理论、计算机技术、数据库技术综合开发出的软件系统。本章给出了具体的滚珠丝杠副设计计算、校核及选型的实例，并且将修正计算公式集成到该系统。 第五章，对全文所作的研究内容进行了总结与回顾，重点介绍了论文的创新点和特色，并对今后的工作前景做了展望。更多还原

【Abstract】 With the development of the technology of machenical manufacture, technics, material smelting and heat treatment in the recent years, more and more domestic and foreign manufacturing have attached importance to the ball screw,which is one of the preferred parts of precision linear drive. So on the basis this dissertation is to discuss and research the dynamic load rating of the ball screw.This dissertation is composed of the following parts:The first chapter reviews the history of ball screw,summarizes its current status,developing trend and some research results of this field domestic and aboard. After that this paper brings forward the subject’s research background,significance, feasibility and the research content and the expecting targets. Finally it shows the whole frame of this article.The second chapter narrates the ball screw’s theory sources and formulas,and then analyses the impacting factors on the geometry manufacture dimension for its dynamic load rating,such as the diameter of the ball,the lead and so on.Material factor of the ball screw is analysed at first,afterwards the helix angle to the dynamic load rating,and then the correction formular is given out.At last contrasting the datum among the correction values,the stylebook values and the new account values it shows for the advantages of the correction formula.In the fourth chapter,the design,calculation and check system for ball screw as a whole was a software system,based on the design theory of ball screw,computer technology and database. It also gives an example of the system and integrates the correction formula into the system.Finally,this dissertation summarizes the research work,emphasizes the paper’s innovation and trait,and gives us the future work of this research.更多还原
