锥套联接是利用锥面的楔形作用实现轴和轮毂的联接，它适用于三角带轮、平皮带轮、同步齿形带轮、链轮、联轴器等部件与轴之间的联接。

Finally, based on the theory of Timoshenko beam, a beam model of this crankshaft is built, which is compared with solid model. The results indicate that this beam model can meet the needs of calculation precision and calculation efficiency. With this beam model, the condition in which real loads are put on the crankshaft is simulated. The displacement curves、velocity curves、acceleration curves of the main journals and the pulley of this crankshaft and torsion vibration curve of the pulley are then gained. With these curves, the dynamic characteristic of the crankshaft is analyzed. The conclusion indicates that this crankshaft has good dynamic characteristic.

最后利用Timoshenko梁理论建立了曲轴的梁单元模型，将此梁单元模型与体单元模型进行了比较，结果表明梁单元模型能够满足精确度和计算效率的要求；利用该梁单元模型，模拟了实际条件下的载荷作用时曲轴的响应，得到了曲轴各主轴颈和皮带轮端的位移、速度、加速度曲线以及皮带轮端的扭转振动曲线，分析了曲轴的动态特性，结论表明该型曲轴具有良好的动态特性。

After test and analysis of internal and external used tightening pulley made of different materials on compositions of material quality,metallographic structure,and hard and worn surface morphology,it showed that the service life of the import-tightening pulley made of 20CrNiMo steel was longer than that of the domestic product.

By using dynamics analysis software RecurDyn to establish a model for the prototype of a belt conveyor, this essay reaches through simulation research the conclusion that during the initial startup phase, it is necessary to maintain a lag between the speed of the tail pulley and that of the head pulley, mainly because it takes a certain amount of time for the elastic wave to travel through the belt to reach the tail of the conveyor.

应用动力学分析软件RecurDyn建立了带式输送机的样机模型，通过仿真研究，得出在起动初始阶段，尾部滚筒速度要滞后于头部滚筒速度一定时间，这主要是由于弹性波在输送带中进行传播到达尾部需要一定的时间；并且在起动阶段，输送带的张力比稳定运行时变化大，起动时间越长，输送带出现的最大张力越小。
