3.冲击旋转机构—螺纹连接系统的参数对冲击旋转机构载荷和拧紧螺纹连接所需冲击循环个数的影响 在研究条件下,拧紧螺纹连接过程中嵌牙与套筒上的力矩可由比例因子M_(ΚΠ)与A_K及A_(Κπ)之乘积来确定,后两个量是在螺纹连接具有加强的硬塑性特性条件下,用电子计算机解方程式(1)～(4)的结果。 在计算嵌牙与套筒上的力矩时曾经假定:在模拟拧紧螺纹连接的过程中K_(ΚΠ)的值是不会改变的,也就是说I_6、C_K和ω均为常数。应当看到,在冲击扳手的冲击旋转机构中,I_6和C_K的值在拧紧螺纹连接的过程中是
3. Impact rotation mechanism - the parameters of the threaded connection system on the impact of the rotating mechanism load and tighten the screw connection required number of impact cycles under the conditions of research, tightening the torque on the crochet and the sleeve can be screwed by the scale factor M_ (ΚΠ) and A_K and A_ (Κπ), the latter two quantities are obtained by solving the equations (1) - (4) with the computer under the condition that the screw connection has enhanced hard plastic property. When calculating moments on the fillet and sleeve, it is assumed that the value of K_ (KΠ) does not change during the simulation of the tightening of the screw connection, that is, I_6, C_K and ω are constant. It should be noted that in the impact wrench impact rotation mechanism, the values of I_6 and C_K during screwing are
