Bearing installation method: changan new leopard bridge bearings how to change

In the knowledge of the relevant data of the enterprise sauvy solution center will be a good hours will be the tooling ready to use; Use sauvy carbon nano polymer materials to repair equipment. Do we have to take into account the shaft rotating at time of thermal material itself, so the greater the bearing, is a -, ~ clearance fit, big and not more than, clearance fit, the standard of GB/T to cooperate with rolling bearing journal provides common tolerance zone, common tolerance zone is defined for the shell hole, as shown in figure. Surface hardness and carburized layer depth of the raceway normal type BUEHLERMICROMET microhardness meter testing and white spot in the hardness of sample and hardness gradient, determine the two sample surface hardness and carburized layer depth. How electric cars bearing replacement: introduction to add up the rear wheels level, has a screw face downwards, mat board on the shaft, with a hammer percussion rear axle, unload motor cover, replace the bearing. Its advantage is good cohesive force, good pressure resistance, abrasion resistance and have metal comprehensive mechanics performance of elastic deformation and so on to realize online repair, machine repair, repair efficiency is high, don't need a large number of disassembly, to equipment hours - a situation Hours to complete. Gear end leakage % ~ % of total leakage, therefore, quickly determine the cause of the malfunction, take proper measures to solve, is the equipment for safe operation of the guarantee. With quiet operation, low cost, can carry on the radial load and axial load, the advantages of low friction, low calorific value, high speed turn; The drawback is that unable to bear impact load or radial and axial load. After we for bearing the corresponding protective measures, can obviously feel bearing wear greatly reduced, of course, we must not only pay attention to the protection timber mill bearing part, the inside of the lumber mill other vulnerable parts also need to pay attention to regular maintenance. Bearing temperature is mainly by the rolling friction between the roller and the inner and outer ring raceway, the sliding friction between the roller and cage, roller end and sliding friction between the inner and outer ring guard, the quantity of heat of the friction between the roller and lubrication oil. Centrifugal fan bearing lubricating oil during normal use, half a year time should be changed, at least for the first time, when using about operation hours later, the first oil change time in ~ months, should check the oil times a week later, such as lubricating oil without metamorphism, the oil change working time can be extended to ~ months, provisions must be used when the brand lubricating oil ( On the general regulations) And the old oil within the tank after put clean and clean thoroughly to insert the new oil. With anhydrous ethanol clean and repair parts, until boiled away; With nylon cage bearing can in - °- ° under long-term continuous stable work, work should not be more than hours when °, transient temperature peak of °. Oils have impurities; , N and NU type cylindrical roller bearings will datum in the direction of the spindle shaft shoulder installation, shall ensure that in the process of testing ring does not produce axial displacement.
