Spherical bearing and dynamic cone inspection before installation

Spherical bearings and spherical bearings are installed. Spherical bearings are also called bowl-shaped tiles. Spherical bearing blocks are also called bowl-shaped watts. The spherical bearing is cast from a copper alloy and is fixed on the bearing block with a round pin, in order to prevent loosening of the round pin and filling of the zinc alloy. Otherwise, during inspection and maintenance, when hanging the starting cone, due to the looseness of the pin, the spherical surface tile may be stuck on the spherical surface of the movable cone by the lubricant. In this way, during the process of lifting the cone of motion, the spherical tiles will drop at any time and cause accidents.

During maintenance, the oil hole of the bearing and the oil groove of the oil retaining ring must be cleaned. If the plug is blocked, not only the flow of the oil will be affected, but also the oil will overflow from the oil retaining ring to the water seal, wasting the oil. The spherical bearing seat is over-fitted and is tightly seated in the bore of the crusher frame, and the key is not skewed into the groove to prevent it from swaying in the recess of the bore, and the horizontal contact is checked with a feeler gauge. Face close. When installing, it must also pay attention to the water pipes, oil retaining rings, spherical tiles and external seals that are connected to it, so as not to be damaged. The pipes should be properly cleaned and cleaned to prevent clogging. After the installation is completed, it should be covered with a cover immediately to prevent dust from entering people.

Dynamic cones are a commonly used complete set of spare parts for mining equipment. Care should be taken to check if the center hole of the spindle is unblocked and clean the cone surface and the spindle before loading into the crusher. When loading, in order to avoid damaging the edge seal of the water seal and the slinger on the spherical bearing seat, the spindle should be slowly loaded along the point on the vertebral bush on the balance weight side. Prior to this, put the lead wire that measures the upper edge of the vertebral bushing on the point of the wound. After the moving cone has been seated on the spherical bearing, the starting cone is lifted again, the flattened lead wire is taken out, and the thickness thereof is measured to know how much the upper mouth gap of the vertebral bush is.
