三角皮带传动初定中心距是否合理,取决于对中心距系数K的选择是否合理。本文探讨了中心距系数K与其他有关参数的关系,并给出了合理选择中心距系数的封闭图,在该封闭图上选取K值可以大大减少返工的可能性。 本文还指出了某些设计规范中初定中心距计算方法的缺陷。本文作为良好的设计工具而有益于机械设计工作者。
Whether the initial center distance of the V-belt drive is reasonable depends on whether or not the center distance coefficient K is selected properly. This paper discusses the relationship between the center distance coefficient K and other related parameters, and gives a closed graph that reasonably selects the center distance coefficient. Selecting the K value on this closed graph can greatly reduce the possibility of rework. This article also points out the flaws of the initial center distance calculation method in some design specifications. This article serves as a good design tool for machine design workers.
