| 摘 要： | 文章分析了牙轮钻头滑动轴承接触力学性质的影响因素。在Marshek和Chen提出的理论基础上,对接触问题中的系数矩阵和间隙函数进行修正,同时采用新的确定两体接触区域的方法,分析计算了牙轮钻头浮动套轴承在不对正情况下与牙轮(或牙爪)接触的应力,并推导了间隙—接触应力的一般表达式。 |
| 关 键 词： | 牙轮钻头 浮动套 轴承 接触应力 |

| Abstract: | This paper analyses the factors that affect the contact stress of rock bit journal bearing.Based on the theory of Marshek and Chen,the paper modifies the coefficient matrix and clearance function of the contact,uses a new method to ascertain the contact area of two bodies,analyses and calculates the contact stress between the floating journal bearing and the cone (or the leg) under disalignment,and comes up with the common expression of clearance-contact stress. |
| Keywords: | rock bit floating ring journal bearing contact stress |
