At the same time , the system vibration also made the paired gears enter into meshing in advance or and seceding of a couple of laggingly 同时,系统振动还使啮合齿对提前或迟后进入啮合、提前或迟后退出啮合。
When bears enough loading , actual contact tooth number will exceed theoretic contact tooth number , which makes the loading capacity of the gears increased dramatically 三环传动在足够大的载荷作用下,实际啮合齿数会大于理论啮合齿数,使得三环减速器中齿轮副的承载能力大大提高。
By considering the contact between the teeth and utilizing the face to face contact model with contact element and coulomb friction model , the author have developed a computing method for plastic load of tooth - locked quick actuating pressure vessel based on finite element stress analysis and stress categorization 摘要通过接触单元来数值模拟啮合齿的接触过程,建立了基于整体有限元分析的齿啮式快开压力容器塑性载荷计算方法。
Aimed to the two deficiencies of three - ring gear transmission , the dissertation will analyze these two aspects . the first , according to the finite element model of gear pair of three - ring gear reducer , the dissertation is aimed to analyze the multi - tooth meshing effect of three - ring gear reducer using finite element method , and the number of teeth contacted simultaneously , their load distribution characteristics and the von mises stress change are gained 针对三环减速器以上两点的不足之处,本文将对以下两方面进行分析:首先,本文以三环减速器齿轮副有限元模型为研究对象,利用有限单元法对三环减速器多齿啮合效应进行分析,得到三环减速器传动时的实际接触齿数、啮合齿载荷分配以及vonmises应力变化规律。
The main research results are as follows : the friction contact between teeth in the tooth - locked quick closure device is studied , and the simulation is made to the contact conduct between the teeth utilizing the face to face contact model with contact element and coulomb friction model , the whole finite element model of tooth - locked quick closure device is created 本文主要有以下成果: ( 1 )对齿啮式快开装置中啮合齿间存在的摩擦接触现象进行了研究,利用接触单元法采用面-面接触模型和库仑摩擦模型对齿间的接触行为进行数值模拟,建立了齿啮式快开装置的整体有限元模型。
