三叉杆式万向联轴器的误差分析

The Error Analysis of the Tripod Universal Joint

在三叉杆式万向联轴器的运动分析的基础上,充分考虑到机构制造和安装的不精确性、运动副轴承的间隙、作用于连杆上力及温度变化引起的连杆变形等因素,进行了三叉杆式万向联轴器运动误差分析。结果表明,可通过合理选取各种结构参数,使运动精度控制在允许的范围之内。

The motion error of the tripod universal joint is analyzed on the basis of kinematic analysis. In the analysis process the manufacturing errors, as sembly error, bearing clearance and the deformation of the connecting rod are considered. The results show that the motion precision can be controlled in the allowable range by choosing the structural parameters correctly.
