摘　　要：以ANSYS为平台,利用有限元方法对矿用牙轮钻头牙轮齿孔过盈配合进行了有限元计算,并分析了牙齿和齿孔应力分布规律及过盈量对其的影响。所得到的结论与武汉冶金设备制造公司钻头厂实验所用的参数数据基本一致,因而是科学、可行的。The over - fixation of mine - used rotary drill bit tooth hole was calculated by the finite element method on ANSYS, also analyzed the distribution laws of tooth hole and tooth stress field and influence of the over - fixation. This method is scientific, useful due to the result according with the experiment data of Wuhan Metallurgical Equipment Manufacture Works.
