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.
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)。
If either the number of sun or ring gear is not multiple of planet gear, system will run effectively, with lower impaction of tooth mesh in and out.
行星轮与内齿圈齿数不为行星轮个数的整数被时,轮齿的啮入、啮出对系统的冲击小,系统的效率高。
The approach presented to achieve the modification coefficient and the minimum tooth number is applicable to the silent chain mechanism with all kinds of pitches.
