哪位英语大神能帮我把下面两句中文翻译成英文，不要机译，要准确，谢谢

齿轮传动是应用非常广泛的机械传动形式，但普通齿轮传动机构的承载能力有限，传动比太大时体积也会变得很大，所以出现了行星齿轮传动机构。本次设计是对一个二级行星齿轮减速器进行结构设计并使用UG进行三维建模。

Answer 1

Gear transmission is widely used form of mechanical transmission, but the capacity of general gear transmission is limited, while the transmission ratio is too large, the volume become very large, so the planetary gear transmission mechanism appeared. This design is about a structure design of a double planetary gear reducer and three-dimensional modeling by UG.

Answer 2

But most people would be chaste
