The temperature of the sliding bearing of the mini cement plant increases. During the operation of the mini cement plant, the head base of the mini cement plant slides and the temperature of the bearing suddenly rises. This phenomenon is mostly due to the sinking of the head base and the overall advance of the grinding body. And inclined, the spherical shoulder of the mini cement plant and the flange root of the hollow shaft pass through extrusion contact and rotational friction, which generates heat and causes the temperature to rise rapidly. This situation may cause the mini cement plant to tilt, and the meshing of the large ring gear and the pinion will form an axial angle, and the teeth will be cut with each other, which will increase the difficulty of meshing, cause loud noise and aggravate vibration, and in severe cases will cause the mini cement plant to stop. After the phenomenon occurs, it is necessary to stop the machine for inspection, weld and lengthen the grounded foot bolts, wedge the pads, and raise the bearing seat, which can control the temperature of the sliding bearing and the sound of the transmission part.
