齿轮组
When designing a gearset one cannot consider torque alone. 设计齿轮组时至考虑扭矩是不够的。
The cycloidal equidistant-curve worm gearset is the new type of worm and worm gear transmission equipment. 摆线等距曲线蜗轩是一种新型的蜗杆传动。
Traditional transmissions use a gearset that provides a given number of ratios (or speeds). 传统变速箱使用提供既定比率（或速度）的整套齿轮。
