Double crank four- ring- plate- type pin- cycloidal planetary reducer is a new type of cycloid - pin gear planetary reducer, and it has many metirs. This article is about the study of parameterization design of this type of reducer, the purpose is to improve the efficiency of its serialization design.

双曲柄四环板针摆行星减速器是具有多种传动优点的新型针摆行星传动，文章从提高其系列化设计效率的角度出发，研究该种减速器的参数化设计方法。

Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.

为大幅度提高其承载能力、传动效率和可靠性诸指标，我们创新研究出来的多种结构双曲柄环板式针摆行星传动，其特点是不仅保留着原摆线针轮行星减速器同时啮合齿数多，总法向力与总圆周力间夹角小，摆线轮与针轮齿均为硬齿面等本质上的优点；而且又具有环板式传动省去输出机构且输出轴刚性好，转臂轴承移至行星轮外，从而传递的转矩可以成倍提高的优点。
