How to solve the shake of the main shaft of the wood pellet machine
1. Tighten the locking screw on the main gland, and then turn on the machine to check whether the main shaft is still shaking. If the main shaft is still shaking at this time, then remove the main gland, pad the main shaft with a copper rod, and use a sledge hammer The spindle is driven in the direction of the ring mold, and then the spindle seal cover is removed to check whether the spindle bearing is intact. Generally, if the gap is too large, the bearing should be removed and replaced with a new bearing, and then the spindle should be locked in order. 2. In the process of installing the main shaft, pay attention to the squareness of the inner ring of the main shaft bearing so that the main shaft can be assembled in place. The distance between the end faces of the two sides of the main shaft and the end face of the rotating wheel should be kept at about 10 cm. If it is found that the gap is too large, the key slot fit gap is large, the safety pin fit gap is large, etc., the above parts should be replaced. Then check again whether the main shaft of the wood pellet machine shakes. 3. After the main shaft of the granulator is normal, the distance between the pressure roller and the die should be adjusted correctly, and the distance should not be adjusted. 4. Check whether the main shaft of the granulator is tightened. First remove the oiling system, remove the main shaft gland, and check whether the disc spring is deformed. If the disc spring is flat, then it is time to replace it.
