鼓形齿联轴器的改进设计与分析

摘要

以一台门式起重机的起升机构为例,首先介绍了鼓形齿联轴器的计算方法,然后以鼓形齿作为分析对象,对其中一对啮合齿进行三维建模.再将鼓形齿模型导入有限元分析软件,对鼓形齿啮合副的载荷接触状态进行应力分析.将公式算法结果与有限元分析结果进行比较,对该类型卷筒联轴器的设计分析具有一定的指导意义.%Taking the hoisting mechanism of a gantry crane as an example, the calculation method of the crown gear coupling is introduced. Three-dimensional modeling of one pair of meshing teeth on crown gear is built and introduced into the finite element analysis software. The stress contact state of the crown gear meshing pair is analyzed. Results comparison between formula algorithm and finite element analysis has certain guiding significance to the design analysis of this type of reel coupling.
