摘要
行星轮系结构紧凑、传动效率高,在工业制造领域中运用广泛;对于具有自锁特性的机构,行星轮系存在广阔的运用空间。基于传动比法分析了3K(Ⅲ)型行星轮系的功率流向及效率公式,通过对该种行星轮系自锁时的效率进行优化处理,改善其运行性能,从而得到提高传动效率后的行星齿轮组反向自锁的传动比设置以及相应的效率大小。首先,利用基本公式求解周转轮系的传动比;其次,针对不同的情况分析周转轮系的功率流向;然后,综合上述条件绘制出效率曲线,并结合实例分析轮系自锁时的传动比状况;最后,通过具体案例验证了该方案的准确性和有效性。该方法能够得出存在反向自锁现象、行星轮系效率最大化时的传动比参数。
The planetary gear train has compact structure,high transmission efficiency,and is widely used in industrial manufacturing.There is a wide application space for the planetary gear train of the self-locking mechanism.In this study,the power flow direction and efficiency formula of the 3K(Ⅲ)type planetary gear train are analyzed,and the operation performance is improved by optimizing the efficiency of this kind of planetary gear train when it is self-locking.Thus,the setting of the transmission ratio and the corresponding efficiency of the reverse self-locking planetary gear set with higher transmission efficiency can be obtained.Firstly,the transmission ratio of the epicyclic gear train is solved by using the basic formula.Secondly,the power flow direction of epicyclic gear trains is analyzed according to different conditions.Thirdly,the efficiency curve is drawn based on the above conditions and the transmission ratio of the self-locking gear train is analyzed with an example.Finally,through detailed case studies,the accuracy and efficacy of this approach are verified,providing the transmission ratio setting for maximizing the efficiency of the planetary gear train during reverse self-locking scenarios.
