A mounting method that uses thermal expansion to convert a tight fit into a loose fit by heating the bearing or housing. It is a common and labor-saving installation method. This method is suitable for the installation of cylindrical roller bearings with large interference. Before hot-loading, put the bearing or separable bearing ring into the oil tank and evenly heat it at 80-100°C, then take it out of the oil and install it on the shaft as soon as possible. In order to prevent the end face of the inner ring and the shaft shoulder from not fitting tightly after cooling, the bearing can be axially tightened after cooling. When the outer ring of the bearing is tightly fitted with the bearing seat made of light metal, the hot-fitting method of heating the bearing seat can be used to avoid the mating surface from being scratched. When heating the bearing with the oil tank, there should be a mesh grid at a certain distance from the bottom of the box, or hang the bearing with a hook. The skf bearing cannot be placed on the bottom of the box to prevent heavy impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank. , Strictly control the oil temperature not to exceed 100 ℃ to prevent the tempering effect and reduce the hardness of the ferrule. 1. Before installing the bearing on the shaft, the fixing pin of the bearing jacket must be pulled out, and the surface of the journal must be polished and cleaned, and the journal should be oiled to prevent rust and lubricate (allow the bearing to rotate slightly on the shaft). 2. Apply lubricating oil on the mating surface of the bearing seat and the cylindrical roller bearing, and install the skf bearing into the bearing seat. Then put the assembled bearing on the shaft together with the nsk bearing seat. Push to the desired location for installation. 3. Do not tighten the bolts that fix the bearing seat first, so that the bearing shell can rotate in the bearing seat. Also install the bearing and seat on the other end of the same shaft, turn the shaft a few times, and let the bearing itself find the correct position automatically. Re-tighten the bearing housing bolts. 4. Install eccentric sleeves. First put the eccentric sleeve on the eccentric step of the inner sleeve of the bearing, and tighten it by hand along the rotation direction of the shaft. Then insert the small iron rod into or against the countersunk hole on the eccentric sleeve. Hit the small iron rod with a hammer in the direction of rotation of the shaft. Make the eccentric sleeve firmly installed, and finally lock the hexagon socket head screw on the eccentric sleeve. The bearing is a precision component, and the cylindrical roller bearing and grease are polluted and will not run. In addition, all of the bearings that have been sealed with grease maintenance-free, at least 14% of the contamination is only significantly caused by the use of skf bearings in a small proportion of all bearings that fail early. Bearings have excellent manufacturing and design capabilities to provide a variety of harsh working conditions sealing solutions.
