Ⅰ球磨机联轴器的改进φ1500×3000球磨机采用减速器减速皮带联轴器周边传动。这种联接形式，半联轴器d1、d2与轴伸采用配合加平键联接，生产现场出现振动、噪声大，对中性差，往销折断，键槽被压溃，装卸、定位较难等问题。经反复研究，现改用内外雄中间套无键联接替代传统的 Ⅰ ball mill coupling φ1500 × 3000 ball mill reducer reducer belt coupling around the drive. This form of coupling, half couplings d1, d2 with the axis of the joint plus Plus flat key, the production site vibration, noise, poor neutral, to break the pin, the keyway crushed, handling, positioning difficult and so on. After repeated studies, is now replaced by male and female middle sets of keyless joints to replace the traditional
