After analyzing the structure of the Iron Ore Impact Crusher, it can be found that there are 4 sets of bearings inside, and the distribution is mainly as follows: two sets of bearings are connected between the eccentric shaft and the movable shaft, and two between the eccentric shaft and the frame are used. The bearing connection, as can be seen from this description, the bearing has a very important influence on the construction and working process of the equipment, but the bearing life is limited, when it is damaged, there will be a phenomenon of "boring car". In order to reduce the occurrence of this phenomenon, it is necessary to ensure the quality of the bearing, so it is very important for the selection of the bearing. Here is to introduce the problem that the Iron Ore Impact Crusher bearing needs to pay attention to when selecting the type.
First, because the equipment is in operation, the bearing should adapt to the high-speed and high-strength working pressure, and the rolling bearing can meet the requirements of the external load, and should exert the load capacity of the bearing itself as much as possible. The radial load is greater than the axial load. Spherical bearings should be used in the case of large span of fulcrum and large deformation of the shaft. Therefore, spherical roller bearings can be selected in the Iron Ore Impact Crusher;
Second, in the accuracy selection, first the bearing inner and outer ring tolerance is ±0.05mm, the general accuracy is ordinary level, to reduce the damage of the Iron Ore Impact Crusher bearing, the bearing accuracy can be changed from ordinary level to C3 level , higher precision;
Three, the clearance of the rolling bearing is divided into radial clearance and axial clearance, which respectively indicate that one ferrule is fixed, and the other circle is radially and axially from one extreme position to the other. The amount of movement. Experimental analysis shows that the working clearance value that makes the bearing life larger is a negative value slightly smaller than zero. Considering the changes caused by the temperature difference between the inner and outer rings and the load factor, it is possible to select better dimensional tolerances and radial clearance tolerances for the bearings. In the assembly process of the Iron Ore Impact Crusher, the bearings are matched, and the bearing is matched according to the machining tolerances of the inner bore and the eccentric shaft, so that the tolerances are in a better state.
