本文介绍以重量最轻为原则配置滚子链传动的方案,同时提供一组较优方案供选择。对于所提供的各方案,除给出表征相对重量的目标函数值外,还给出各自的过载能力指标及同时考虑重量和过载能力的统一目标函数值。上述三种指标从不同角度反映设计方案的优劣程度,它们所得到的结论往往是不统一的,这就为设计者在选择方案时提供了更广泛的依据。 This article describes the weight of the principle of the principle of configuration roller chain drive program, while providing a set of more options to choose from. For each solution provided, in addition to the objective function values ​​that characterize the relative weights, we also give their respective indicators of overload capacity and the unified objective function values ​​that consider both weight and overload capacity. The above three indicators reflect the strengths and weaknesses of the design schemes from different angles. The conclusions they draw often are not uniform, which provides the designer with a broader basis for choosing a scheme.
