万向联轴器有多种类型 ,球笼等速万向节只能产生轴间角而没有轴向滑移 ,也称为固定端 ,笔者仅阐述它的运动特性、等速性及偏心量等问题。1　固定端的工作原理1 .1　固定端的结构固定端的结构见图 1 ,ｅ1是星形套的偏心量 ,即星形套球面中心线与沟道中心线的距离。ｅ2为钟形壳的 Universal coupling There are many types of ball cage constant velocity universal joint can only produce axial without axial slip, also known as the fixed end, I only describe its movement characteristics, constant velocity and eccentricity And other issues. 1 fixed end of the working principle 1.1 fixed structure of the fixed end of the structure shown in Figure 1, e1 is the amount of eccentricity of the star-shaped sleeve, that is, the center line of the radial spherical sleeve and the centerline of the channel distance. e2 bell-shaped shell
