Cone crusher engine drive system design is not reasonable or in unreasonable conditions of use, the drive system will occur in the strange noise failure. The noise failure is due to excessive vibration of the transmission system, the collision between mechanical parts, resulting in a variety of noise. If the mechanical transmission system occurs gears hitting teeth, gear teeth off and other faults, will seriously affect the normal work of the cone crusher. Therefore, the transmission system needs to be monitored in real time.
Secondly, the phenomenon that the upper and lower frame of the cone crusher moves can also cause strange noises, which is mainly caused by broken bolts, and the solution is to replace or tighten the loose bolts.
crusher troubleshooting:
1.Solder the three thread heads on the crusher separately with solder. The surface of the welding head is required to be smooth and free of burrs and false welding. If the welding is not firm or not smooth, perform welding again.
2.A small amount of scratches or slight large-area wear or shedding of the journal can be repaired by hand grinding or grinding with emery; it can also be repaired by brush plating on site. Severe wear can be repaired by the following three methods.
3. When the crusher is jammed by a large piece of gangue or other debris, it must not be lifted by hand or other tools, and it must be stopped before processing.
4. Use manual arc welding to surfacing on the surface of the journal, and then perform cutting to reach the original design journal size. When surfacing, the surfacing process should be selected correctly to prevent bending and deformation of the traction shaft. When surfacing welding, the electrode should be selected reasonably, the diameter of the electrode should be small, and the current intensity should not be too high. After surfacing welding, a reasonable centering reference should be selected to ensure the accuracy of the operation of the crusher after assembly. Put on the journal, complete the worn journal, and make another steel sleeve. The inner hole and journal of the steel sleeve should be an interference fit (S7/h6), and the outer diameter should be processed according to the original design dimensions and tolerances. The steel sleeve should be hot mounted on the journal.
5. Rotate the worn-out crusher's journal, and perform a small amount of processing on the premise of ensuring the designed surface roughness. Then, the bearing is prepared according to the processed journal size and its deviation and the matching performance of the original design.
