挠性万向节(Flexible universal joint) :靠弹性零件传递动力,具有缓冲减振作用。
第二节 万向节结构方案分析 一、十字轴式万向节(Hooke's universal joint)
▪结构:
万向节叉(Yoke) 十字轴(Spider) 滚针(Needle roller) 、套筒(Sleeve) 、 油封(Oil seal) 、轴承盖(Bearing cap) 注油嘴(Injection nozzle)、 安全阀(溢流阀(Relief valve))
双十字轴万向节的等速传动条件(1=2)
Constant velocity requirements of double Hooke's universal joint
问题:汽车变速箱输出轴与驱动桥 主减速器输入轴的轴线相对位置是 否平行?(Is the gearbox output shaft parallel to the final drive input shaft?)
