用常规方法设计链传动时,要确定的基本参数有链节距P,链列数G及小链轮齿数Z_1。设计时一般是先选定G及Z_1,通过相应计算确定链节距P。若G、Z_1选择不合适,其设计结果往往不理想。由于计算过程繁杂,手算难于实现多方案比较。本文介绍的程序设计方法,则可根据设计者意图,迅速提供不同节距,不同列数的传动方案供选择。使用该程序时,设计者可以完全脱离手册资料,除设计任务书规定的设计条件外,一切参数都由程序产生。在输入的数据中,程序将检查小链轮转速n_1,小链轮齿数Z_1及初始中心距Ao是否合理,如遇有不合理的输入,则指出其错误,如参数n_1和Ao不合理,程序将提供允许选取的范围,由设计者
When designing the chain drive by the conventional method, the basic parameters to be determined are the chain pitch P, the number of chain columns G and the number of small chain teeth Z_1. Design time is generally first selected G and Z_1, through the corresponding calculation to determine the chain pitch P. If G, Z_1 choose inappropriate, the design results are often not ideal. Due to the complexity of the calculation process, it is difficult to achieve multiple program comparison. This article describes the programming method, you can quickly according to the designer’s intention to provide different pitches, different columns of the transmission options to choose from. The use of the program, the designer can completely divorced from manual information, in addition to the design requirements specified in the design task, all parameters are generated by the program. In the input data, the program will check the small sprocket speed n_1, small sprocket number Z_1 and the initial center distance Ao is reasonable, in case of unjustified input, then pointed out that the error, such as parameters n_1 and Ao unreasonable, the program The range of allowable picks will be provided by the designer
