直径2.6、3.0米大直径管振动芯模目前采用的是四台电机分别驱动四串偏心子振动组的结构形式。四台电机和偏心子组沿芯模内壁作等分布置,它们之间由十字支架连接。通过使用,发现有以下两个问题: (1)电机间的十字支架。固定振动子轴承座的槽钢与简体的焊缝等,经常出现开裂(开裂后,电机负荷过大); (2)成型时,四台电机一般采用成对方式启动(即1、3和2、4,见图1)。在启动第一对电机后再启动第二对电机时,往往有电
The large-diameter tube vibration mandrel with diameter of 2.6 and 3.0 meters currently adopts the structure form that four motors drive four series of eccentric vibration groups. Four motors and eccentric subgroups are equally spaced along the inner wall of the mandrel, and they are connected by a cross bracket. Through the use, found the following two problems: (1) cross bracket between the motor. Frequently cracking occurs in the channel steel that holds the vibrator bearing housing and the simplified weld seam (after the cracking, the motor load is too large); (2) Four motors are generally started in pairs (that is, 1, 3, and 2) during molding. , 4, see Figure 1). When starting the first pair of motors and then starting the second pair of motors, there is often electricity
