Ore crusher is a mechanical equipment used for the crushing and processing of ore in the process of sand and stone production. The common ore crusher has jaw crusher, counterattack crusher, hammer crusher, cone crusher and so on. The performance of different ore crusher is very different. Shanghai zhuya mining machinery is mainly to remind the vast majority of the ore crusher. The users pay attention to the bearing of the ore crusher, and the bearing is the weak point of the ore crusher.

The bearing clearance of the ore crusher is too small, which causes the bearing temperature to rise too high; the grade of the lubricating oil of the ore crusher is not chosen properly, the viscosity is too large or the viscosity is too small to form the oil film, which can cause the bearing temperature to rise too high. Especially when the viscosity of the lubricating oil is large, it not only increases the internal friction between the lubricating oil molecules, but also increases the friction between the oil and the metal, so the heat is too much. The rubber plate of the rubber plate coupling is too thick, the rubber plate is too thick and the deflection is insufficient, resulting in the bearing rivalry, the friction intensifies and the heat is too much.

The cause of heating of the bearing of the ore crusher is known. The user can solve the heating problem of the bearing of the ore crusher according to the reason. The user can adjust the bearing clearance to meet the requirements. The coaxiality of the positive motor and the rotor of the crusher is found to be less than 0.5mm. The level of the motor rotor and the rotor of the crusher are found on the shaft neck of the two bearings of the motor, the flywheel of the crusher rotor and the outer ring of the bearing respectively, and then rechecked with a connected pipe, and the straightness of the center line of the motor and the crusher is checked with the method of drawing the wire of the wire crane to meet the requirements.
