不带分配机构的球笼式等角速万向节由四个零件组成,即球形亮、保持架、星形球,钢球,其结构形式见图1。从结构原理上看,球笼万向节的特点为:球形壳钢球滚道曲率中心a和星形球钢球轨道曲率中心b不重合,它们的中心a,b分别对称地位于万向节中心o的两侧,且oa=ob,当万向节轴间夹角为O°时,钢球靠内外子午滚道的交叉而确定在正确的位置上,见图1A-O-A剖面。
The cage-type isocenter with no distribution mechanism consists of four parts, namely a spherical light, a cage, a star ball and a steel ball. The structure of the ball cage is shown in Fig.1. From the structural principle point of view, the features of the cage joint are: the curvature center a of the spherical shell ball raceway and the curvature center b of the ball of the star ball do not coincide, and their centers a and b are symmetrically located at the universal joint Center o on both sides, and oa = ob, when the universal joint axis angle of O °, the ball by the intersection of the inner and outer radial track to determine the correct position, see Figure 1A-OA section.
