What is the working space of the eccentric sleeve and the eccentric shaft of the cone crusher?
After the taper crusher, the eccentric shaft sleeve and the bevel gear are stably loaded into the frame, the meshing clearance of the gear is measured by means of a lead screw or a rotating shaft. The Bush and the frame of the eccentric shaft sleeve, a large gap, and the eccentric shaft sleeve by rotating the straight bushing in always, so the cone crusher cone gear center, with the gap of the eccentric shaft sleeve and rack bushing half radius of circular motion, so in the actual gap value is bigger. If the backlash of the gear meshing is small, additional load will be generated on the gear and transmission shaft.
Preparation before installation: load the adjusting pad onto the bottom cover, and then push the thrust bearing in the order of the screw on the adjusting pad. When the eccentric shaft is installed, the lower pad shall be stuck in the groove of the bottom cover so as to be reliable. The top pad of the taper crusher thrust bearing is fixed on the eccentric shaft sleeve by screw. Then use the special lug on the gear to fit it into the bush. In the installation process, you need to check the cone type crusher eccentric sleeve and carefully rack straight bushing clearance, and the clearance under the spindle sleeve size, because the gap is too large or too small will cause the machine is not operating properly, causing a certain degree of damage to the equipment. The eccentric sleeve is aligned with the gap of the liner bushing. The clearance between the spindle and the shaft sleeve should be satisfied, and the balance contact between the two can be ensured, so that the eccentric swing of the eccentric shaft can be carried out normally. These clearances should be strictly designed according to the design.
Cone crusher eccentric sleeve and the circular gear connected by oblique key, the eccentric shaft is sleeved on the bushing machine, in order to make the balance of inertia force crushing cone swing movement of the eccentric sleeve and the frame of the support material set along the length of contact, and the eccentric shaft sleeve webbing pressed in the rack bushing, often in the big bevel gear cast on balance block.
