Abstract

The design of the main shaft type universal joint preliminary design.
In this paper, the cross axis of universal joint development survey of the comprehensive elaboration, several universal joint of the classified introduction, the universal shaft structure of the system is analyzed, and the in a car and carried out on the basis of the universal shaft type of simple design, transfer torque according to preliminary selection the axis of the of size, according to  the basic structure to determine the size of the other structure and the preliminary check, the last of the shaft with ug software of the universal joint drawing, finally it is also introduced the shaft type of universal joint technical requirements and maintenance, etc.
 Key words: Universal joint; Design; Transmission shaft
