This thesis discusses the following. First, we use the condition of inference and the concept of wildhabor cone to design the addendum circle. Second, we use TCA technique to obtain the relationship between the slip track and the angle of action, which then leads to the calculation of contact ratios. We can then design the tooth face width and the numbers of teeth based on contact ratios.

本文一开始先对空间渐开线齿轮之齿冠圆范围使用齿轮干涉条件与Phillips提出的Wildhabor Cone进行设定，再利用Litvin提出的齿面接触分析方法，得到空间渐开线齿轮对在啮合过程中作用角与滑动轨迹之间的关系，藉由此关系可以建立一套设计流程来调整齿面宽以及齿数等参数，使其能符合设计需求。

When the lock ring simultaneously with the question cone gear engagement ring gear, cone after contact friction moment in the role of the rapid speed of gear to reduce to synchronize with the speed equivalent to lock ring, the two synchronous rotation, relative to gear Central lock synchronization speed is zero, thus inertia torque also disappeared, then in force under the impetus of engagement sets unhindered and synchronization lock Gear engagement ring, and further engagement with the question of gear engagement ring gear and completed Shift process The topics mainly through the Pro / E synchronization software for the car to three-dimensional modeling structural design, and through the parameters of the design process to achieve its structure, and on this basis, the use of ANSYS FEM software structure of the typical synchronization And a finite element analysis, through structural analysis of its structural design is reasonable to assess and make recommendations to improve the design

当同步锁环内锥面与待接合齿轮齿圈外锥面接触后，在摩擦力矩的作用下齿轮转速迅速降低到与同步锁环转速相等，两者同步旋转，齿轮相对于同步锁环的转速为零，因而惯性力矩也同时消失，这时在作用力的推动下，接合套不受阻碍地与同步锁环齿圈接合，并进一步与待接合齿轮的齿圈接合而完成换档过程本课题主要是通过Pro/E软件对汽车同步器进行三维造型结构设计，并通过参数化实现其结构设计程序化，在此基础上，利用ANSYS有限元软件对典型同步器结构进行有限元计算与分析，通过结构分析对其结构设计的合理性作出评价并提出改进设计建议

Under this manufacturing condition, the pair of non-circular gears can mesh accurately.

证明了采用渐开线圆柱齿轮刀具在数控插齿机上加工的1对非圆齿轮副传动时，在其按设计的已知节曲线工作时，两非圆齿轮副的齿廓具有单一的接触点，即能保证正确的啮合关系，为深入分析非圆齿轮副的传动机理提供了前提。

Considering the problems of spurgear precise plastic forming, such as high deformation resistance, poor flowability and especial hardness to fill cant of gear, technological plan was developed based on precise plastic forming technique, successive control principle and consecutive local deformation theory. Moreover, structures of the rolling preform die and the die with up and down wellrounded forcer for stamping-extrusion and bulge-extrusion combining forming were designed too.
