Roots fan gear replacement has a lot of people have consulted us, today Huadong fan to share with you, about this knowledge:

All used old gears should be assembled according to the orientation marks made during disassembly and in accordance with the original wear marks to avoid poor tooth meshing. If a new gear, should be replaced at the same time the master and slave wheel. Otherwise, the old and new gear pairing is bound to cause poor contact.

In operation, the main gear is generally installed first, followed by the driven gear. In the gear and shaft using flat key connection occasions, the first flat key installed on the shaft, and in the side of the key coated with molybdenum disulfide or high-viscosity oil, and then the gear shaft holes and shaft relative to the hole, so that the keyway on the hole aligned with the flat key to install the gear on the shaft, the commonly used method of installation of the following two kinds of: Roots blower

1, when the gear and shaft taper fit, the first active gear set on the active shaft, gear locking part of the round nut, and then use a copper rod to knock the gear end face, tighten the round nut. After it is sufficiently locked, the round nut is backed off, and a thrust washer is added to formally lock the gear. Next, set the driven gear to the driven wheel, rotate the sub according to the specified running direction disk, check the clearance between the two impellers. And by changing the circumferential position between the follower gear ring and the hub, the impeller orientation is adjusted, after confirming the amount of impeller clearance sign requirements, the follower gear is locked.

2. In the case of a cylindrical fit, it is necessary to use greater pressure to fit the gear onto the shaft because of the tighter fit. Usually, a metal sleeve is placed against the gear end face, and then the sleeve is struck with a hand hammer, or the gear end face is struck directly with a brass rod to push the gear toward the shaft, and the gear is locked in place after it is pushed up against the shoulder of the shaft.
