Screening machine vibrator bearing loading and unloading process

The vibrator of the screening machine is of different types and its bearing removal and assembly methods are also different.

For shaft eccentric vibrator bearing disassembly and assembly, due to shaft eccentric vibrator is one of the common vibrators, this type of vibrator is generally used spherical roller bearings. When disassembling such vibrator bearings, first remove the shaft end stop ring, counterweight flywheel and seal end cap, and open the fixing bolts of the bearing seat, and use the top screw (usually three) to push out the bearing seat. Due to the loose fit of the bearing inner ring and the shaft, the bearing moves outward with the bearing seat until it slides out of the shaft.

After removing the bearing seat, use the top screw to push the bearing outer ring out of the bearing seat. The assembly of such vibrator bearings in cement production lines is in the exact opposite order of disassembly. Before the bearing is assembled, the inner diameter of the bearing housing bore and the outer neck of the journal should be checked from several directions.

The assembly of bearings and housings requires the use of mounting sleeves or copper rods to mount the bearings in place within the housing. One of the bearing seats is first mounted on the screen box, the eccentric shaft is put on, and the other bearing seat is installed. Prior to installation, the bearings and all parts that are to be used with them must be cleaned.

Of course, the different types of vibrators can also make the installation order of the vibrators different. The commonly used shaft sleeve eccentric vibrator for fixing the vibrator assembly on the screen box by the taper sleeve needs the use of a mounting sleeve to simultaneously mount the bearing on the shaft and the sleeve holder, and then installs the sleeve cover and the labyrinth seal ring to form the sleeve. Vibrator assembly, reinstalled on the screen box. Regardless of the mounting method of the bearing, attention must be paid to the positioning of the bearing.
