Strength design from considering the tooth surface pressure lubrication condition and dedendum intensity of two aspects. 强度设计是从考虑润滑条件的齿面压力和齿根强度两个方面进行的。
The test results show that the X-joint has distinctly stress con centration,which should be considered seriously in design. 试验结果表明，该节点有明显的应力集中现象，应在强度设计中留有余地。
