crank axle

through mesh generation it sets up the finite element analysis model of major components to achieve the modal neutral files of its crank axle, body and head.

通过网格划分建立主要零部件的有限元分析模型，由有限元模型得到曲轴、机体与气缸盖等的模态中性文件。

As a result, it can decrease production routine and reduce production casts, which will lay foundations for practical research on parts such as crank axle.

本研究为曲轴等非调质钢零件的实用性研究提供参考。

on the basis of kinematic analysis, the power equations of kinetic energy theorem are introduced to calculate the influence of each part of the beam pumping unit on the output axle torque of crank respectively, and the expressions for solving the crank output axle torque are derived.

在此运动分析的基础上，应用动能定理的功率方程，分别考虑游梁式抽油机各部件对曲柄输出轴扭矩的影响，得到求解曲柄输出轴扭矩的表达式。

the utility model has the advantages of increasing the mechanical strength of the crank of the bent axle so that the utility model will not break even being overloaded.

优点是增强了曲轴曲柄的机械强度，使其在超负荷的情况下运行也不易折断。
