我们常用的圆柱齿轮传动比小,体积大、结构笨重。
We have used the CYLINDRICAL gear transmission ratio of small, large, heavy structure.
有些车的转向系角传动比是可变的,这种转向器采用齿轮齿条式,它在中间而不是外部,有不同的齿密度(每寸齿数)。
Some cars have variable-ratio steering, which uses a rack-and-pinion gear set that has a different tooth pitch (number of teeth per inch) in the center than it has on the outside.
例如,两个齿轮的传动机构中,如果一齿轮的尺寸是另一齿轮的两倍,那么传动比就是2:1。
For instance, in a device with two gears, if one gear is twice the size of the other, the ratio would be 2:1.
