In order to ensure the normal operation of the jaw crusher, not only the manufacturing quality and manufacturing technology of the bearings need to be strictly checked, but also the installation and disassembly must be carried out in strict accordance with the instructions. Specifically, the disassembly and assembly of the bearing of the jaw crusher needs to pay attention to the following matters:
Precautions for bearing disassembly
1. To protect the shaft head from being damaged, a sleeve with a bearing surface thickness of 40 mm can be made on the shaft head, so as to avoid the flywheel directly hitting the eccentric shaft and damaging the shaft head.
2. When hitting the eccentric shaft with a crane crane, the operation of the flywheel should be emphasized. The centerline of the flywheel and the centerline of the eccentric shaft should be kept on a straight line as much as possible.
3. The position of the impact bearing should be selected properly, so that the bearing is first disengaged from the moving jaw cavity, if the axis is offset, continue to strike after correcting until all leave the moving jaw cavity.
Precautions for bearing installation
1. To install the eccentric shaft and the bearing on it into the moving jaw, the process is more complicated. To put the moving jaw upright, use a flywheel under it to make it a certain height away from the ground, try to make the axis of the moving jaw cavity perpendicular to the horizontal plane, and then burn firewood under it to let the flame pass through the cavity, Red Star Heavy Industries recommends After heating the moving jaw cavity for about 1.5 hours, lift the eccentric shaft and drop it vertically into the cavity.
2. In order to ensure that the bearing is installed accurately, the oil seal, end cover and retaining ring of the bearing are installed in advance at the shaft end of the lifting end, and then the external bearing is installed. At this point, the end cover and bearing are installed in place.
3. After the eccentric shaft is ready for installation, keep the jaw stationary, and then install another flywheel, using three more suitable stud bolts, one end into the three screw holes of the shaft head, and then, hang the take-off wheel horizontally. Put the flywheel up and down slowly, the shaft hole passes through the three bolts, the flat key is aligned with the keyway, put the shaft end cover on the three bolts, add the backing plate, screw on the nut, and press the flywheel down, at the same time Hit the flywheel hard so that the flywheel is installed quickly.
