The traditional pin-cycloid planetary drive has a series of essential advantages such as small volume, light weight, wide range of speed ratio, high efficiency, and quiet operating as well. On the other hand, it has a natural weak point that the tumbler bearing, which supports the cycloidal gear on the arm is placed inside the cycloidal gear, therefore the size of the bearing is restricted due to the geometry of the gear.

摆线针轮行星传动具有体积小，重量轻，传动比范围大，传动效率高，传动平稳且可靠等一系列优点，但它也有一薄弱环节，即转臂轴承处于摆线轮上输出机构的内部，径向尺寸受到限制，从而限制了摆线针轮行星传动更充分地发挥其承载能力。

The results are as follow:The diploid chromosome number of Taihe Silkies was 2n=78,the basic number of chromosome arms was AF=90 and the sex chromosome type was ZZ/ZW.According to the measured relative length,arm ratio and centromeric index,the first 10 pairs of macro-chromosomes are described as follows:No.1 ,9 and Z,W chromosomes were metacentrics,No.2,4,7 were submetacentrics,and No.3,6,8,10 were telocentrics.Studies on Taihe Silkies′ G-band showed that the first 10 pairs of macro-chromosomes can be divided into 29 zones and 190 bands.
