摘 要

齿轮传动是机械传动中应用最广泛的一种传动，具有承载能力大，效率高，传动比准确，结构紧凑，工作可靠等优点。该系统主要用在直齿锥齿轮传动参数化设计。在实际设计过程中，知道几个已知参数，如传动功率、传动比、齿轮每天工作时间等，通过这些已知条件计算出齿轮的主要参数：大端模数m、锥距R、齿宽b、分度圆直径d等。设计过程中有一些设计参数需要从图表中查取，在选择完毕后，经过设计程序计算，最终显示出制造者所需要的参数值。本次设计简化了设计计算工作，提高了工作效率，比较方便、实用。

Abstract The gear transmission is the most widely used in mechanical transmission, a transmission, with a large carrying capacity, high efficiency, transmission than accurate, compact, reliable, etc.. The system is mainly used in the straight bevel gear drive parametric design. In the actual design process, several known parameters, such as transmission power, transmission, gear daily working hours and other known conditions to calculate the main parameters of the gear: big endian modulus m, the cone distance R, the tooth width b, pitch circle diameter d. Some design parameters in the design process need to find out from the chart, select After, after the calculation of the design process. In the end, showing the values of the parameters needed by the manufacturer. This design simplifies the design calculations to improve work efficiency, more convenient and practical.

Key words: Visual Basic; gear; design
