Abstract The no-spin design methodology of the traction continuously variable transmission (CVT) is the latest achievement in the field of CVT mechanism research. According to this methodology, four basic no-spin traction CVT mechanisms are acquired. In order to obtain more no-spin traction CVT mechanism topologies, a novel Configuration Factor Table (CFT) method for the configuration synthesis of basic no-spin traction CVT mechanisms is proposed, of which the main idea is from the basic law of separation and free combination of genes. Then the five main steps of configuration synthesis using this CFT method are described in detail. Based on this method, the configuration synthesis case studies of logarithmic CVT and conical CVT are carried out. The results show that 14 variant mechanisms of logarithmic CVT and 10 variant mechanisms of conical CVT are obtained. Among them, the swing-logarithmic CVT, rolling-logarithmic CVT, swing-conical CVT and rolling-conical CVT are considered to have the potential to become the new generation of high-power transmitting and high-efficiency traction CVTs.

一种新型无旋牵引无级变速器构型综合方法研究

摘要 牵引式无级变速器（CVT）的无旋转设计方法是CVT机构研究领域的最新成果。根据这种方法，获得了四种基本的无旋转牵引 CVT 机构。为了获得更多的无旋转牵引CVT机构拓扑结构，提出了一种用于基本无旋转牵引CVT机构构型综合的新型配置因子表（CFT）方法，其主要思想是从基本分离定律和基因的自由组合。然后详细描述了使用这种 CFT 方法进行配置合成的五个主要步骤。基于该方法，进行了对数CVT和锥形CVT的配置综合案例研究。结果表明，得到了14种对数CVT变型机构和10种锥形CVT变型机构。其中，摆动对数CVT、滚动对数CVT、摆动锥形CVT和滚动锥形CVT被认为具有成为新一代大功率传动和高效牵引CVT的潜力。
