The sound of the cone crusher
is relatively loud, so if there is noise, it will be ignored. This requires our staff to pay more attention on a daily basis to prevent the noise from causing irreparable damage to the cone crusher. Let ’s see The reason caused the noise problem of the equipment.
1. The clearance of the main components of the cone crusher. The clearance between the main shaft of the cone crusher and the cone bush is more complex than that of a general sliding bearing. The clearance value is large and different, and the upper mouth is smaller and the lower mouth is larger. In this way, the size of the gap is very important. If it is not appropriate, noise will occur and it will easily generate heat, which will affect the operation of the cone crusher equipment. The other is the clearance between the eccentric shaft sleeve and the frame bushing. Here too, a large value is required, but the load is too large and noise is generated. Therefore, the clearance of key components must be set according to requirements.
2. Motion analysis of cone crusher. In the process of cone crusher operation, inertial force will be generated, causing shock vibration and noise. At present, it is generally balanced by adding a counterweight on the large gear to reduce shock and vibration and reduce noise to the degree of the hard *. However, when choosing the balance weight, it should be as small as possible, otherwise it will affect the normal work of the cone crusher.
3. The processing accuracy of the cone crusher components is not high. The design and processing of the cone crusher components are unqualified, or the accuracy is not high, which leads to the poor quality of the overall component. It can be imagined that the installation on the equipment will affect the overall operation of the cone crusher equipment. There will be constant friction, so that the noise of the equipment cannot be eliminated fundamentally. In general, the internal cause is not eliminated and the noise will continue to exist.
