摘要为了提高V型带传动设计效率及可靠性,通过分析传统设计中图表数据的特点,提出了V带传动设计中有关数据、表格和线图的程序化方法及较实用的可靠模型。并采用Visual Basic完成了计算机辅助设计的编程。
V带计算机辅助设计的内容包括V带的设计计算,小带轮二维图绘制及三维图建模等。在V带设计计算过程中,除了要查取许多标准外,还要对照大量的设计图表取得设计参数。对于复杂的图表的处理,例如V带单根带的基本额定功率和额定功率增量的查询,单纯的用VB 语言来处理,不仅会增加很大的工作量,而且还会是编织出来的程序很繁琐。为了编程方便,我们采用拟合公式对这些参数进行处理。调用Autocad 绘制小带轮的二维、三维图是本次设计的重点。本论文将实现利用VB 在外面调用Autocad 实现自动绘图。50610
但是,由于编程时使用拟合公式和简化了某些设计步骤,使得设计的结果有一定误差,而且该系统只是用于普遍使用的V带设计,所以,要想得到更广泛、更高精度的V带设计结果,必须对系统进一步完善并对设计结果进行优化处理,才能达到真正实用高效的效果。

ABSTRACT To enhance efficiency and reliability of V-belt drive design, with analysis of the characteristics of chart data in the traditional design, a practical reliability model and a procedure method of the data, tables and charts in the design of V-belt are proposed. The programming of computer aided design based on Visual Basic is realized.
Computer-aided design of V-belt includes V belt calculations, drawed Autocad and complated modles automaticly . In the process of V-belt design , there are many standard checked, and a large number of design parameters controlled. For complex diagrams, such as basic rated power of a single V-belt and its incremental queries , dealing with simple VB language will not be completed but increaseing the quantity of the work . To programming convenience , we use the fitting formula of these parameters . It is an important content to draw 2D and 3D map of small pulley . The thesis will achieve automaticly calling Autocad .
However, due to the use of programming fitting formula and simplify some of the design process, making the results of the design has some errors, and the system is limited . In order to get a broader and more accurate results of V belt design , the system must be designed to optimize the results and achieve real practical and efficient results.
