定子和转子是液压转向机构及转子泵中的重要零件,它们属于针轮摆线啮合副。为了保证排量及额定压力的稳定,并保证最大的使用寿命,其偶配间隙原则上愈小愈好。从进口机件的偶配间隙来看,一般都在0.03毫米以下,转子在定子中能自如地做行星运动,这里除转子的外摆线等距曲线误差很小外,就是它保证了定子的制造精度了。定子的技术指标主要有以下几个方面: 1、针轮位置度在径向方向反映出来的齿
Stator and rotor are the important parts of the hydraulic steering mechanism and the rotor pump. They belong to the pin wheel cycloidal meshing pair. In order to ensure the displacement and pressure stability, and to ensure maximum service life, the even distribution of the gap in principle the smaller the better. From the point of view of even the mating parts of the imported parts, generally 0.03 mm or less, the rotor can freely move in the stator. Here the error of the equatorial curve of the outer cycloid of the rotor is very small, and it ensures that the stator Manufacturing accuracy. Stator technical indicators are the following aspects: 1, the position of the needle wheel position in the radial direction of the teeth reflected
