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）。
A rack-and-pinion gear set is enclosed in a metal tube, with each end of the rack protruding from the tube.
整个齿轮齿条式转向器装载金属壳内，其齿条从转向器伸出来与转向摇臂连接。
Rack and pinion: Mechanical device consisting of a Bar of rectangular cross section (the rack), having teeth on one side that mesh with teeth on a small gear (the pinion).
齿条和小齿轮：一种机械装置，由一条矩形截面的杆(齿条)和一个与齿条上的齿相啮合的小齿轮组成。
In this paper, the meshing theory of rack and pinion steering gear with variable ratio is studied systematically.
对汽车变速比齿轮齿条式转向器的啮合原理进行了系统研究。
As one of the individual variable vanes is rotated by an actuation source, the other variable vanes of the variable vane array are rotated a like amount by the rack and pinion gear interface.
当其中一个可变叶片由一驱动源转动时，可变叶片阵列上的其他可变叶片通过齿条和小齿轮的相互作用而转动一个相同的量。
