How to install the gear of Roots blower?

The used old gear should be assembled according to the direction mark of the disassembly position to avoid poor meshing of the tooth surface. If a new gear is replaced, the main wheel and driven wheel should be replaced at the same time. Otherwise, the fitting of new and old gears will cause poor contact.

During operation, the driving gear is usually installed first, and then the driven gear. When the gear and shaft are connected with the flat key, first install the flat key on the shaft, coat the side of the key with molybdenum disulfide or high viscosity oil, and then the gear shaft hole is opposite to the shaft, so that the keyway on the hole is aligned with the flat key, and the gear is installed on the shaft. Roots blower manufacturers usually use the following two installation methods:

When the taper fits with the gear and shaft, first put the driving gear on the driving shaft, and install the nut on the locking part of the gear. Then, knock the end face of the gear with a copper bar and tighten the nut. After locking, take out the round nut and lock it with the thrust washer. Then install the driven gear on the driven wheel, rotate the rotor according to the specified running direction, and check the clearance between the two impellers. Adjust the orientation of the impeller by changing the circumferential position between the driven ring and the hub, and lock the driven gear according to the volume requirements of the impeller clearance.

2. In the case of cylindrical fit, the gear is installed on the high-pressure shaft due to close fit. The metal sleeve is usually installed on the surface of the gear, and then directly hit the end face of the sleeve or gear with a copper bar to push the gear to the shaft, and then push the gear to the shoulder to lock it.
