Ball mill is based on the main gear

　　The ball mill is grounded, installs and adjusted the transmission part with a main gear. Make the pinion width of the pinion evenly even uniformly in both sides of the tooth surface of the large gear. The tooth surface of the pinion is parallel to the tooth surface of the large gear, and the tooth side gap remains 0.25 mm (about hard box cigarette packaging paper). From the contact marks of the size gear, the contact marks should account for more than 60% of the full length, and the height of the contact marks accounts for about 40%. If the contact marks are biased toward the end of the width of the tooth surface, that is, the tooth surface is not parallel. If the transmission large gear has a case where there is a case, it means that the gear gap is too small, and the pinion should be left out of the large gear. The axis of the ball mill should be horizontally, measured at both ends of the hollow axis in the upper end, the height should be consistent, and the feed end is allowed to be higher than the discharge end of 1 mm. At the outer space shaft, the bearing seat cover The gap around the hollow shaft and the bearing pressure cover should be substantially consistent, and the inner and outer blocks should be substantially consistent.
